Enterprise Networking, Security, and Automation ( Version 7.00) – CCNA (200-301) Certification Practice Exam

1. An instructor is reviewing student answers on a previous term exam to prepare for a lecture on IPv6. What would be a good point for the instructor to make when explaining an IPv6 GUA (global unicast address)?

  • It is considered a best practice to use the IPV6 GUA address of the router as the default gateway address for Windows hosts.
  • It can be configured statically or assigned dynamically on a router.
  • It can only be configured statically on a host interface by using the ipv6 address command.
  • It is routable on the IPv6 internet.

2. An administrator needs to implement a 2.4GHz WLAN that requires multiple APs. Which two are characteristics of the 2.4GHz channels? (Choose two.)

  • They can provide faster data transmission for wireless clients in heavily populated wireless networks than 5GHz channels.
  • Each channel is separated from the next channel by 20 MHz.
  • There are 11 channels for North America identified by the 802.11b standard.
  • If three adjacent APs are required, the non-overlapping channels 1, 21, and 41 are recommended.
  • Each channel is allotted 22 MHz bandwidth.

3. A technician must accommodate at least 500 subnets from address 172.16.0.0/16. What is an appropriate subnet mask and corresponding number of available host IP addresses per subnet to meet the requirement?

  • 255.255.255.128 and 126 hosts
  • 255.255.255.0 and 128 hosts
  • 255.255.255.192 and 126 hosts
  • 255.255.255.224 and 128 hosts

Explanation: The network address 172.16.0.0 has a default mask of 255.255.0.0 (/16). This address has 16 bits in the network portion and 16 bits in the host portion. To have at least 500 subnets, you need to borrow 9 bits (subnets) from the host portion (2^9 = 512 subnets), leaving 7 bits to create hosts. Thus the resulting netmask is 255.255.255.128, and the number of hosts per subnet is 2^7 = 128 – 2 = 126 hosts.

4. Refer to the exhibit. A PC with the MAC address of 0800.069d.3841 attached to port Fa0/8 is sending data to a device that has the MAC address of 6400.6a5a.6821. What will the switch do first to handle the data transfer?

CCNA (200-301) Certification Practice Exam Answers (ENSA v7.0) 1

  • The switch will add the address 0800.069d.3841 to the MAC address table.
  • The switch will send the frame to ports Fa0/4 and Fa0/6.
  • The switch will flood the frame out all ports except port Fa0/8.
  • The switch will send the frame to port Fa0/6.
  • The switch will add the address 6400.6151.6821 to the MAC address table.

Explanation: Every frame that enters a switch is checked for new information to learn. It does this by examining the source MAC address of the frame and port number where the frame entered the switch:

If the source MAC address does not exist in the MAC address table, the MAC address and incoming port number are added to the table.

5. A network engineer is giving a tour of the company network operations center to a college class. The engineer is trying to describe how a WAN and connectivity to the internet relate to the network infrastructure. Which statement correctly describes network infrastructure and network communication?

  • Communication across the internet requires application of recognized technologies and standards.
  • LANs are used to connect WANs around the world.
  • A LAN connects small networks to large global networks.
  • The internet is a worldwide collection of interconnected networks owned by an organization.

Explanation:The internet is not owned by any individual or group. Ensuring effective communication across this diverse infrastructure requires the application of consistent and commonly recognized technologies and standards as well as the cooperation of many network administration agencies.

6. A network engineer is designing a borderless switched network in a hierarchical fashion. Which guideline might cause the engineer to implement a three-tier layer model?

  • Fault isolation is one of the primary purposes of the distribution layer.
  • Access layer L2 switches connect to distribution layer L3 switches, which implement routing, quality of service, and security.
  • The core layer provides differentiated services to various classes of service applications at the edge of the network.
  • The access layer provides aggregation of Layer 2 broadcast domains.

Explanation:The access layer represents the network edge, where traffic enters or exits the campus network. Traditionally, the primary function of an access layer switch is to provide network access to the user. Access layer switches connect to distribution layer switches, which implement network foundation technologies such as routing, quality of service, and security.

7. Two students are discussing routers and one statement that is said between them is accurate. Which statement is that?

  • A directly-connected network is automatically added to the routing table of an adjacency neighbor if both routers are Cisco routers.
  • A gateway of last resort is added to the routing table when the router boots up.
  • Remote networks can only be added after they are learned by routers through dynamic routing protocols.
  • A default route provides a way for packets that do not match a specific route in the routing table to be forwarded.

8. What are two benefits of using virtualization? (Choose two.)

  • The operating system of the virtual machine does not require licensing when it is virtualized.
  • The virtual machine is no longer dependent on a specific hardware platform.
  • Because all virtual operating systems are contained within a single virtual network, networking connections are simplified.
  • The performance of a virtual machine is faster than the performance of the operating system running on physical hardware.
  • Multiple virtual machines can be running simultaneously on a single physical device.

9. Students in a data networking class are reviewing materials in preparation for a quiz. Which statement describes the operation of an access control method for shared network media?

  • The controlled-based access method, used on legacy bus-topology Ethernet LANs, decided the order of each device to transmit.
  • In the CSMA/CD method, when two devices transmit at the same time, a collision is detected and data is resent immediately.
  • The CSMA/CA method attempts to avoid collisions by having each device informing others how long the media will be unavailable.
  • In a contention-based multiaccess network, each node has its own time to use the medium.

Explanation:CMSA/CA does not detect collisions but attempts to avoid them by waiting before transmitting. Each device that transmits includes the time duration that it needs for the transmission. All other wireless devices receive this information and know how long the medium will be unavailable.

10. A network administrator is designing an IPv4 addressing scheme and requires these subnets.

1 subnet of 100 hosts
2 subnets of 80 hosts
2 subnets of 30 hosts
4 subnets of 20 hosts

Which combination of subnets and masks will provide the best addressing plan for these requirements?

  • 9 subnets of 126 hosts with a 255.255.255.128 mask
  • 3 subnets of 126 hosts with a 255.255.255.192 mask
    6 subnets of 30 hosts with a 255.255.255.240 mask
  • 3 subnets of 126 hosts with a 255.255.255.128 mask
    6 subnets of 30 hosts with a 255.255.255.224 mask
  • 1 subnet of 126 hosts with a 255.255.255.192 mask
    2 subnets of 80 hosts with a 255.255.255.224 mask
    6 subnets of 30 hosts with a 255.255.255.240 mask

Reference: VLSM Calculator Online
CCNA (200-301) Certification Practice Exam Answers (ENSA v7.0) 2

IPv4 subnets that require 100 and 80 hosts are provided by creating subnets of 126 usable addresses, each of which requires 7 host bits. The resulting mask is 255.255.255.128.

Subnets that require 30 and 20 hosts are provided by creating subnets of 30 usable addresses, each of which requires 5 host bits. The resulting mask is 255.255.255.224.

Creating nine subnets, each consisting of 126 usable addresses, would waste large numbers of addresses in the six smaller subnets.

11. A group of network technicians is discussing IPv6 multicast processes. What is a feature of one type of IPv6 multicast address that should be discussed?

  • A solicited-node multicast address is similar to the all-routers multicast address.
  • It can be a source or a destination address.
  • It has the prefix fe00::/8.
  • The all-nodes multicast group has the same effect as an IPv4 broadcast address.

12. Which LAN attack allows for identification of connected Cisco devices which are sending unencrypted broadcasts?

  • STP attack
  • CDP reconnaissance
  • ARP attack
  • address spoofing attack

13. What is a characteristic of the REST API?

  • evolved into what became SOAP
  • most widely used API for web services
  • used for exchanging XML structured information over HTTP or SMTP
  • considered slow, complex, and rigid

14. A network administrator is using the Cisco DNA Center to monitor network health and to troubleshoot network issues. Which area should the administrator use to perform these tasks?

  • ASSURANCE
  • PROVISION
  • PLATFORM
  • POLICY

15. Which term describes the process of managing configuration changes of network devices in an orderly fashion?

  • version control
  • orchestration
  • automation
  • provisioning

Explanation: Configuration management tools typically include automation and orchestration. Automation is automatically performing a task on a system. Arranging the automated tasks into a coordinated process or workflow is called orchestration.

16. Which function of the Cisco intent-based networking system (IBNS) enables network operators to express the expected networking behavior that will best support the business intent?

  • ACL analysis
  • assurance
  • activation
  • translation

Explanation: The translation feature of Cisco IBNS enables network operators to express the expected network behavior that will best support the business intent.

17. Which type of API would be used to allow authorized salespeople of an organization access to internal sales data from their mobile devices?

  • private
  • partner
  • public
  • open

18. Refer to the exhibit. In the displayed JSON data representation, which symbol should be used to replace the question mark in lines 2 and 15?

CCNA (200-301) Certification Practice Exam Answers (ENSA v7.0) 3

  • square brackets [ ]
  • commas ,
  • double quotation marks ” “
  • braces { }

19. What action takes place when a frame entering a switch has a multicast destination MAC address?

  • The switch will forward the frame out all ports except the incoming port.
  • The switch forwards the frame out of the specified port.
  • The switch adds a MAC address table entry mapping for the destination MAC address and the ingress port.
  • The switch replaces the old entry and uses the more current port.

Explanation: If the destination MAC address is a broadcast or a multicast, the frame is also flooded out all ports except the incoming port.


20. A network engineer is configuring secure remote access to a Cisco router. Which two commands would be issued in the line configuration mode of the router to implement SSH? (Choose two.)

  • login local
  • crypto key generate rsa
  • transport input ssh
  • username admin secret ccna
  • ip ssh version 2

21. When an end device requests services from a DHCPv4 server it receives a host IPv4 address and a subnet mask. Which two other IPv4 addresses are also typically provided to a DCHPv4 client? (Choose two.)

  • DNS server address
  • local HTTP web server address
  • LAN default gateway address
  • LAN NTP server address
  • automatic private IPv4 address

Explanation: LAN NTP server and local HTTP web server addresses are not provided by DHCP. Automatic private IPv4 addresses (APIPA) are used by DHCP clients when the clients fail to connect to a DHCPv4 server.

22. A network engineer wants to synchronize the time of a router with an NTP server at the IPv4 address 209.165.200.225. The exit interface of the router is configured with an IPv4 address of 192.168.212.11. Which global configuration command should be used to configure the NTP server as the time source for this router?

  • ntp peer 209.165.200.225
  • ntp server 192.168.212.11
  • ntp server 209.165.200.225
  • ntp peer 192.168.212.11

23. When testing a new web server, a network administrator cannot access the home page when the server name is entered into a web browser on a PC. Pings to both the IPv4 and IPv6 addresses of the server are successful. What could be the problem?

  • DNS is not resolving the server name to an IPv4 or IPv6 address.
  • ARP is not discovering the MAC address of the server.
  • DHCP has not assigned an IPv4 or IPv6 address to the server.
  • An FTP client must be installed on the PC.

24. A network engineer is using SNMP manager software to monitor and manage network performance. In addition to polling network devices at regular time intervals, the engineer is configuring the devices to generate messages that inform the SNMP manager of specified events. What message type is configured on those devices that allows them to send unsolicited messages?

  • set request
  • get-response
  • trap
  • get-bulk-request

Explanation: A network device stores information for SNMP in the MIB. This information can be sent to the SNMP manager when specifically requested with a get message. Unsolicited messages that are sent when pre-configured specified events occur are trap messages.

25. A wireless network engineer is implementing updated wireless equipment within the company. Which statement describes a wireless security protocol?

  • WPA secures the data using the Rivest Cipher 4 encryption method with a static key.
  • WPA3-Personal uses 802.1X/EAP authentication that requires the use of a 192-bit cryptographic suite.
  • WPA2-Personal is intended for home or small office networks and uses 802.1X/EAP authentication.
  • WPA2-Enterprise is intended for enterprise networks and users must authenticate using 802.1X standard.

26. Refer to the exhibit. Which access list configuration on router R1 will prevent traffic from the 192.168.2.0 LAN from reaching the Restricted LAN while permitting traffic from any other LAN?

CCNA (200-301) Certification Practice Exam Answers (ENSA v7.0) 4

  • R1(config-std-nacl)# permit any
    R1(config-std-nacl)# deny 192.168.2.0
    R1(config)# interface G0/2
    R1(config-if)# ip access-group BLOCK_LAN2 out
  • R1(config-std-nacl)# deny 192.168.2.0
    R1(config-std-nacl)# permit any
    R1(config)# interface G0/2
    R1(config-if)# ip access-group BLOCK_LAN2 out
  • R1(config-std-nacl)# permit any
    R1(config-std-nacl)# deny 192.168.3.0
    R1(config)# interface G0/2
    R1(config-if)# ip access-group BLOCK-LAN2 in
  • R1(config-std-nacl)# deny 192.168.3.0
    R1(config-std-nacl)# permit any
    R1(config)# interface G0/2
    R1(config-if)# ip access-group BLOCK_LAN2 in

Explanation: The correct access list syntax requires that the deny source IP address (192.168.2.0) statement come before the permit statement so that only traffic sourced from the 192.168.2.0 LAN is denied. Then the access list must be applied on interface G0/2 in the outbound direction.

27. An administrator who is troubleshooting connectivity issues on a switch notices that a switch port configured for port security is in the err-disabled state. After verifying the cause of the violation, how should the administrator re-enable the port without disrupting network operation?

  • Reboot the switch.
  • Issue the no switchport port-security violation shutdown command on the interface.
  • Issue the no switchport port-security command, then re-enable port security.
  • Issue the shutdown command followed by the no shutdown command on the interface.

Explanation:To re-enable the port, use the shutdown interface configuration mode command (Figure 3). Then, use the no shutdown interface configuration command to make the port operational.

28. An IT security specialist enables port security on a switch port of a Cisco switch. What is the default violation mode in use until the switch port is configured to use a different violation mode?

  • disabled
  • shutdown
  • protect
  • restrict

Explanation:If no violation mode is specified when port security is enabled on a switch port, then the security violation mode defaults to shutdown.

29. Refer to the exhibit. Which interface on switch S1 should be configured as a DHCP snooping trusted port to help mitigate DHCP spoofing attacks?

Refer to the exhibit. Which interface on switch S1 should be configured as a DHCP snooping trusted

  • G0/23
  • G0/1
  • G0/22
  • G0/24

Explanation:When DHCP snooping is configured, the interface that connects to the DHCP server is configured as a trusted port. Trusted ports can source DHCP requests and acknowledgments. All ports not specifically configured as trusted are considered untrusted by the switch and can only source DHCP requests.

30. Which statement is an accurate description of a VPN type?

  • Site-to-site VPNs are typically created and secured using SSL.
  • In a Clientless VPN the connection is secured using a web browser IPsec connection.
  • In a Client-based VPN, users initiate a connection using VPN client software and the VPN gateway does the data encryption.
  • In a site-to-site VPN internal hosts have no knowledge that a VPN is being used.

31. A network administrator of a college is configuring WLAN security with WPA2 Enterprise authentication. Which server is required when deploying this type of authentication?

  • AAA
  • DHCP
  • RADIUS
  • SNMP

Explanation:WAP2 Enterprise provides stronger secure user authentication than WPA2 PSK does. Instead of using a pre-shared key for all users to access a WLAN, WPA2 Enterprise requires that users enter their own username and password credentials to be authenticated before they can access the WLAN. The RADIUS server is required for deploying WPA2 Enterprise authentication.

32. When configuring a switch for SSH access, what other command that is associated with the login local command is required to be entered on the switch?

  • enable secret password
  • login block-for seconds attempts number within seconds
  • username username secret secret
  • password password

Explanation: The login local command designates that the local username database is used to authenticate interfaces such as console or vty.

33. What term describes a process where a router simply discards any packet that arrives at the end of a queue that has completely used up its packet-holding resources?

  • weighted random early detection (WRED)
  • low latency queuing (LLQ)
  • traffic shaping
  • weighted fair queuing (WFQ)
  • tail drop

34. In an OSPF network when are DR and BDR elections required?

  • when the two adjacent neighbors are interconnected over a point-to-point link
  • when all the routers in an OSPF area cannot form adjacencies
  • when the routers are interconnected over a common Ethernet network
  • when the two adjacent neighbors are in two different networks

Explanation:When the routers are interconnected over a common Ethernet network, then a designated router (DR) and a backup DR (BDR) must be elected.

35. A network engineer has been asked to prepare a router and to ensure that it can route IPv6 packets. Which command should the network engineer ensure has been entered on the router?

  • ipv6 enable
  • ipv6 unicast-routing
  • ipv6 address
  • ipv6 route

36. Refer to the exhibit. Match the packets with their destination IP address to the exiting interfaces on the router. (Not all targets are used.)

Match the packets with their destination IP address to the exiting interfaces on the router

CCNA (200-301) Certification Practice Exam Answers (ENSA v7.0) 5

Explanation: Packets with a destination of 172.17.6.15 are forwarded through Fa0/0. Packets with a destination of 172.17.10.5 are forwarded through Fa1/1. Packets with a destination of 172.17.12.10 are forwarded through Fa1/0. Packets with a destination of 172.17.14.8 are forwarded through Fa0/1. Because network 172.17.8.0 has no entry in the routing table, it will take the gateway of last resort, which means that packets with a destination of 172.17.8.20 are forwarded through Serial0/0/0. Because a gateway of last resort exists, no packets will be dropped.

37. Consider the following static route configured on a Cisco router:

ipv6 route 2001:db8:acad:4::/64 2001:db8:acad:3::2

What remote network is specified in this route?

  • 2001:db8:acad:4::/64
  • 2001:db8:acad:0::/64
  • 2001:db8:acad:3::/64
  • 2001:db8:acad:2::0/64

38. A network administrator configures a router with the ipv6 route ::/0 Serial2/0 command. What is the purpose of this command?

  • to add a dynamic route for the destination network ::/0 to the routing table
  • to enable a router to forward packets for which there is no route in the routing table
  • to forward packets destined for the network ::/0 to the serial 2/0 interface
  • to forward all packets to the serial 2/0 interface

39. What is the purpose of a First Hop Redundancy Protocol?

  • to provide two or more routers working together, sharing an IP and MAC address of a virtual default gateway
  • to provide a physical link to a new default router to replace the unreachable default gateway
  • to provide a dynamic method by which devices on a LAN can determine the address of a new default gateway
  • to provide a list of IP addresses of devices that can assume the role of the forwarding router

40. A network engineer examining the configuration of a Cisco router sees a network entry in a routing table listed with a code O. Which kind of route is this?

  • a route used for the default gateway
  • a route for a network directly connected to the local router interface
  • a route dynamically learned through the OSPF routing protocol
  • a static route

41. What defines a host route on a Cisco router?

  • An IPv4 static host route configuration uses a destination IP address of a specific device and a /32 subnet mask.
  • A static IPv6 host route must include the interface type and the interface number of the next hop router.
  • A host route is designated with a C in the routing table.
  • The link-local address is added automatically to the routing table as an IPv6 host route.

42. Refer to the exhibit. Packets destined to which two networks will require the router to perform a recursive lookup? (Choose two.)
Packets destined to which two networks will require the router to perform a recursive lookup

  • 10.0.0.0/8
  • 128.107.0.0/16
  • 192.168.2.0/24
  • 192.168.1.0/24
  • 172.16.40.0/24
  • 64.100.0.0/16

43. The routing table of a Cisco router has four static routes for network 10.0.0.0. Which route is the best match for a packet entering the router with a destination of 10.16.0.10?

  • S 10.0.0.0/16 is directly connected, GigabitEthernet 0/1
  • S 10.16.0.0/24 [1/0] via 202.16.0.2
  • S 10.16.0.0/16 is directly connected, GigabitEthernet 0/0
  • S 10.0.0.0/8 [1/0] via 202.16.0.2

44. Match the FHRP protocols to the appropriate description. (Not all options are used.)
Match the FHRP protocols to the appropriate description

45. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.
CCNA (200-301) Certification Practice Exam Answers (ENSA v7.0) 6
Which task has to be performed on Router 1 for it to establish an OSPF adjacency with Router 2?

  • Issue the clear ip ospf process command.
  • Change the subnet mask of interface FastEthernet 0/0 to 255.255.255.0.
  • Remove the passive interface command from interface FastEthernet 0/0.
  • Add the network 10.0.1.0 0.0.0.255 area 0 command to the OSPF process.

Explanation: Each interface on the link connecting the OSPF routers must be in the same subnet for an adjacency to be established. The IP address subnet mask on FastEthernet interface 0/0 must be changed to 255.255.255.0. The FastEthernet interface 0/0 is not passive. The 10.0.1.0/24 network is only connected to Router2 so should not be advertised by Router1. The clear ip ospf process command will start the OPSF process on Router1 but will not cause an adjacency to be established if the subnet mask mismatch on the connecting interfaces still exists.

46. What is the recommended Cisco best practice for configuring an OSPF-enabled router so that each router can be easily identified when troubleshooting routing issues?

  • Use the highest IP address assigned to an active interface participating in the routing process.
  • Use a loopback interface configured with the highest IP address on the router.
  • Use the highest active interface IP address that is configured on the router.
  • Configure a value using the router-id command.

Explanation: A Cisco router is assigned a router ID to uniquely identify it. It can be automatically assigned and take the value of the highest configured IP address on any interface, the value of a specifically-configured loopback address, or the value assigned (which is in the exact form of an IP address) using the router-id command. Cisco recommends using the router-id command.

47. In FHRP terminology, what represents a set of routers that present the illusion of a single router to hosts?

  • standby router
  • forwarding router
  • default gateway
  • virtual router

Explanation: In FHRP multiple routers are configured to work together to present to hosts a single gateway router. This single gateway router is a virtual router which has a virtual IP address that is used by hosts as a default gateway.

48. A network administrator is configuring the SNMP function on a Cisco 3500 series WLC. The task is to add an SNMP trap server to which this WLC will forward SNMP log messages. Which tab should the administrator use to add the SNMP trap server information?

  • COMMANDS
  • MONITOR
  • MANAGEMENT
  • CONTROLLER

49. Match the STP port state with the appropriate description. (Not all options are used.)

CCNA (200-301) Certification Practice Exam Answers (ENSA v7.0) 7

Explanation: The details of each port state are shown in the table.

Port State Description
Blocking The port is an alternate port and does not participate in frame forwarding. The port receives BPDU frames to determine the location and root ID of the root bridge. BPDU frames also determine which port roles each switch port should assume in the final active STP topology. With a Max Age timer of 20 seconds, a switch port that has not received an expected BPDU from a neighbor switch will go into the blocking state.
Listening After the blocking state, a port will move to the listening state. The port receives BPDUs to determine the path to the root. The switch port also transmits its own BPDU frames and informs adjacent switches that the switch port is preparing to participate in the active topology.
Learning A switch port transitions to the learning state after the listening state. During the learning state, the switch port receives and processes BPDUs and prepares to participate in frame forwarding. It also begins to populate the MAC address table. However, in the learning state, user frames are not forwarded to the destination.
Forwarding In the forwarding state, a switch port is considered part of the active topology. The switch port forwards user traffic and sends and receives BPDU frames.
Disabled A switch port in the disabled state does not participate in spanning tree and does not forward frames. The disabled state is set when the switch port is administratively disabled.

50. Refer to the exhibit. All the displayed switches are Cisco 2960 switches with the same default priority and operating at the same bandwidth. Which three ports will be STP designated ports? (Choose three.)

CCNA (200-301) Certification Practice Exam Answers (ENSA v7.0) 8

  • fa0/9
  • fa0/21
  • fa0/11
  • fa0/10
  • fa0/20
  • fa0/13

51. Refer to the exhibit. A network technician issues the command show vlan to verify the VLAN configuration. Based on the output, which port should be assigned with native VLAN?

Refer to the exhibit. A network technician issues the command show vlan to verify the VLAN configuration

  • Fa0/12
  • Fa0/20
  • Fa0/24
  • Gig0/1

52. What is the purpose of setting the native VLAN separate from data VLANs?

  • The native VLAN is for routers and switches to exchange their management information, so it should be different from data VLANs.
  • A separate VLAN should be used to carry uncommon untagged frames to avoid bandwidth contention on data VLANs.
  • The native VLAN is for carrying VLAN management traffic only.
  • The security of management frames that are carried in the native VLAN can be enhanced.

Explanation: When a Cisco switch trunk port receives untagged frames (unusual in well-designed networks), it forwards these frames to the native VLAN. When the native VLAN is moved away from data VLANs, those untagged frames will not compete for bandwidth in the data VLANs. The native VLAN is not designed for carrying management traffic, but rather it is for backward compatibility with legacy LAN scenarios.

53. Which is a characteristic of EtherChannel?

  • EtherChannel uses physical ports that have been upgraded to provide a faster connection.
  • EtherChannel configuration is applied to each physical port.
  • STP treats all interfaces in an EtherChannel bundle as a single logical link.
  • STP will not block redundant EtherChannel bundles between two switches.

54. What characteristic describes how data or voice VLANs are configured on a network?

  • WIRELESS
  • SECURITY
  • WLANs
  • MANAGEMENT

57. An administrator issues the show vlan brief command on a Cisco switch and the output shows that all ports are currently assigned to the default VLAN. What conclusion can be drawn?

  • Layer 2 control traffic is not associated with any VLAN.
  • The switch cannot be remotely managed using Telnet or SSH until a management VLAN has been created.
  • All user data traffic will be separated and secured from other users.
  • There is a security risk because the management VLAN and the native VLAN are the same.

  • highest IP address
  • lowest IP address
  • lowest MAC address
  • highest MAC address

Explanation: Only one switch can be the root bridge for a VLAN. The root bridge is the switch with the lowest BID. The BID is determined by priority and the MAC address. If no priority is configured then all switches use the default priority and the election of the root bridge will be based on the lowest MAC address.

  • An AP is easier to configure and to set up than Wi-Fi range extenders.
  • A wireless device has to be associated to an AP in order to have access to network resources.

71. A network engineer is designing a borderless switched network in a hierarchical fashion. Why might the engineer consider using a two-tier layer model?

  • The access layer in this model has different functions from the access layer in the three-tier layer model.
  • It is recommended in smaller campus locations where there are fewer users accessing the network.
  • It consists of a collapsed layer composed of the access and the distribution layer, and a second layer composed of the core layer.
  • The primary function of the collapsed layer is to provide network access to the user.

72. A technician is troubleshooting a network device and suspects there might be a duplex mismatch. What could cause a duplex mismatch?

  • data corruption
  • interconnection of unlike devices
  • interface misconfiguration
  • auto-MDIX detection failure

Explanation: Duplex mismatches are typically caused by a misconfigured interface or, in rare instances, by a failed autonegotiation. Duplex mismatches may be difficult to troubleshoot because the communication between devices still occurs.

73. A pharmaceutical company wants to contract the services of a cloud provider to store employee data and company-specific applications with strict access security. Which type of cloud would be the most appropriate for this scenario?

  • public cloud
  • private cloud
  • hybrid cloud
  • community cloud

Explanation: Private clouds – Cloud-based applications and services offered in a private cloud are intended for a specific organization or entity, such as the government. A private cloud can be set up using the organization’s private network, though this can be expensive to build and maintain. A private cloud can also be managed by an outside organization with strict access security.

What is the significance of the Serial0/0/0?

  • It is the interface on the next-hop router that is directly connected to the 10.2.2.0/30 network
  • It is the interface on the next-hop router that is directly connected to the 10.1.1.0/24 network.
  • It is the R4 interface through which the OSPF update was learned.
  • It is the interface R4 uses to send data that is destined for 10.2.2.0/30.

78. When creating an IPv6 static route, when must a next-hop IPv6 address and an exit interface both be specified?

  • when the static route is a default route
  • when the next hop is a link-local address
  • when the exit interface is a point-to-point interface
  • when CEF is enabled

Explanation: Link-local addresses are only unique on a given link, and the same address could exist out multiple interfaces. For that reason, any time a static route specifies a link-local address as the next hop, it must also specify the exit interface. This is called a fully specified static route.

79. What characterizes a floating static route?

  • It is a less trustworthy route than the primary route.
  • It provides load balancing with another static route to the same destination.
  • It is configured with a lower administrative distance than the primary router
  • It serves as a backup to an OSPF-learned route as long as it is configured with an administrative distance of 105.

80. Which feature on a Cisco router permits the forwarding of traffic for which there is no specific route?

  • next-hop
  • gateway of last resort
  • outgoing interface
  • route source

Explanation: A default static route is used as a gateway of last resort to forward unknown destination traffic to a next hop/exit interface. The next-hop or exit interface is the destination to send traffic to on a network after the traffic is matched in a router. The route source is the location a route was learned from.

  • identity theft
  • adware
  • data interception and theft
  • spyware

107. What is the purpose of the overload keyword in the ip nat inside source list 1 pool NAT_POOL overload command?

  • It allows many inside hosts to share one or a few inside global addresses.
  • It allows a list of internal hosts to communicate with a specific group of external hosts.
  • It allows external hosts to initiate sessions with internal hosts.
  • It allows a pool of inside global addresses to be used by internal hosts.

Explanation: Dynamic NAT uses a pool of inside global addresses that are assigned to outgoing sessions. If there are more internal hosts than public addresses in the pool, then an administrator can enable port address translation with the addition of the overload keyword. With port address translation, many internal hosts can share a single inside global address because the NAT device will track the individual sessions by Layer 4 port number.

  • The switch replaces the old entry and uses the more current port.

111. A technician is reviewing a report of slowness during peak traffic periods and is looking at performance on a particular switch. What should the technician be aware of about memory buffering on a switch?

  • The port-based memory method is more appropriate to asymmetric switching.
  • If shared memory is used, a single frame can delay the transmission of all others in memory because of a busy destination port.
  • The amount of buffer memory required by a port is dynamically allocated when port-based memory is used.
  • Shared memory allows traffic received on one port to be transmitted to another port without moving the data to a different queue.

  • They are configured as trunk interfaces.
  • They are administratively shut down.
  • There is no media connected to the interfaces.
  • There is a native VLAN mismatch between the switches.

Explanation: Interfaces that are configured as trunks do not belong to a VLAN and therefore will not show in the output of the show vlan brief commands.

120. Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)

  • The source port field identifies the running application or service that will handle data returning to the PC.
  • The TCP process running on the PC randomly selects the destination port when establishing a session with the server.
  • UDP segments are encapsulated within IP packets for transport across the network.
  • The UDP destination port number identifies the application or service on the server which will handle the data.
  • TCP is the preferred protocol when a function requires lower network overhead.
  • The TCP source port number identifies the sending host on the network.

Explanation: Layer 4 port numbers identify the application or service which will handle the data. The source port number is added by the sending device and will be the destination port number when the requested information is returned. Layer 4 segments are encapsulated within IP packets. UDP, not TCP, is used when low overhead is needed. A source IP address, not a TCP source port number, identifies the sending host on the network. Destination port numbers are specific ports that a server application or service monitors for requests.

Explanation: Static NAT is a one-to-one mapping between an inside local address and an inside global address. By using static NAT, external devices can initiate connections to internal devices by using the inside global addresses. The NAT devices will translate the inside global address to the inside local address of the target host.

130. In computer network communications which data transfer process does the application layer protocol FTP use?

  • client-server
  • server message block
  • peer-to-peer
  • Gnutella

131. What action takes place when a frame entering a switch has a broadcast destination MAC address?

  • The switch adds a MAC address table entry mapping for the destination MAC address and the ingress port.
  • The switch replaces the old entry and uses the more current port.
  • The switch will forward the frame out all ports except the incoming port.
  • The switch forwards the frame out of the specified port.

132. Which LAN attack involves sending unsolicited ARP replies, with the MAC Address of the threat actor and the IP address of the default gateway, to other hosts on a subnet?

  • ARP attack
  • address spoofing attack
  • DHCP starvation attack
  • DHCP spoofing attack

133. A network engineer is examining the configuration of a router and notices that interface Gi0/0 has been configured with the ip address dhcp command. Which statement describes the IP address condition of this interface?

  • The router interface is configured as a DHCPv4 client.
  • The router is configured as a DHCPv4 server.
  • No IP address is required for this interface to operate.
  • The interface will use an IPv6 address instead of an IPv4 address.

134. What term describes holding packets in memory until resources become available to transmit them?

  • playout delay
  • queuing
  • queuing delay
  • low latency queuing (LLQ)
  • weighted fair queuing (WFQ)

135. What defines a two-tier spine-leaf topology?

  • Everything is two hops from everything else.
  • The spine tier can be implemented with Cisco Nexus 9500 switches connected to each other and to the leaf switches.
  • The APIC controller manipulates the data path directly.
  • The Cisco APICs and all other devices in the network physically attach to leaf switches.

Explanation: In this two-tier topology, everything is one hop from everything else. The leaf switches (Cisco Nexus 9300) always attach to the spines (Cisco Nexus 9500), but never to each other. Similarly, the spine switches only attach to the leaf and core switches. The Cisco APICs and all other devices in the network physically attach to leaf switches. When compared to SDN, the APIC controller does not manipulate the data path directly.

  • DHCP spoofing attack

Case 2:

  • DHCP starvation attack
  • ARP attack
  • address spoofing attack
  • STP attack

138. What term describes a process where a router simply discards any packet that arrives at the end of a queue that has completely used up its packet-holding resources?

  • latency
  • bandwidth
  • tail drop
  • jitter
  • congestion

139. What term describes adding a value to the packet header, as close to the source as possible, so that the packet matches a defined policy?

  • policing
  • traffic marking
  • weighted random early detection (WRED)
  • traffic shaping
  • tail drop

140. What action takes place when the source MAC address of a frame entering a switch is in the MAC address table?

  • The switch forwards the frame out of the specified port.
  • The switch updates the refresh timer for the entry.
  • The switch replaces the old entry and uses the more current port.
  • The switch adds a MAC address table entry for the destination MAC address and the egress port.

141. What action takes place when a frame entering a switch has a unicast destination MAC address that is not in the MAC address table?

  • The switch updates the refresh timer for the entry.
  • The switch resets the refresh timer on all MAC address table entries.
  • The switch replaces the old entry and uses the more current port.
  • The switch will forward the frame out all ports except the incoming port.

142. Which LAN attack prevents hosts from obtaining dynamically assigned IP addresses?

  • DHCP spoofing attack
  • DHCP starvation attack
  • ARP attack
  • VLAN double-tagging attack

Question 50, can someone explain why the DP is 10,13,21?
Because I really think it should be 9,11,20.

The lowest bridge ID will be the root bridge, since all switches are the default priority, S2 should be the root bridge in this case(lowest MAC)(means fa0/9,f0/20 will be DP)

The same mechanism in S1&S3, therefore f0/11 will be DP as well.

Am I misunderstand STP T_T..

38) A network administrator configures a router with the
ipv6 route ::/0 Serial2/0 command. What is the purpose of this command?

  • to add a dynamic route for the destination network ::/0 to the routing table
  • to enable a router to forward packets for which there is no route in the routing table
  • to forward packets destined for the network ::/0 to the serial 2/0 interface
  • to forward all packets to the serial 2/0 interface

Thats not correct.

Right answer: The IPv6 default route (::/0) is a static route used for all traffic that has a destination network not reachable through any other IPv6 route in the routing table.

19. Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)
The source port field identifies the running application or service that will handle data returning to the PC.*
The TCP process running on the PC randomly selects the destination port when establishing a session with the server.
UDP segments are encapsulated within IP packets for transport across the network.*
The UDP destination port number identifies the application or service on the server which will handle the data.*
TCP is the preferred protocol when a function requires lower network overhead.
The TCP source port number identifies the sending host on the network.

Explanation: Layer 4 port numbers identify the application or service which will handle the data. The source port number is added by the sending device and will be the destination port number when the requested information is returned. Layer 4 segments are encapsulated within IP packets. UDP, not TCP, is used when low overhead is needed. A source IP address, not a TCP source port number, identifies the sending host on the network. Destination port numbers are specific ports that a server application or service monitors for requests.
