Question 1 of 417

1. Question
Which technology supports the stateless assignment of IPv6 addresses?
- DNS
- DHCPv6
- DHCP
- autoconfiguration
Correct

Incorrect

Hint
DHCPv6 Technology Overview IPv6 Internet Address Assignment Overview IPv6 has been developed with Internet Address assignment dynamics in mind. Being aware that IPv6 Internet addresses are 128 bits in length and written in hexadecimals makes automation of address- assignment an important aspect within network design. These attributes make it inconvenient for a user to manually assign IPv6 addresses, as the format is not naturally intuitive to the human eye. To facilitate address assignment with little or no human intervention, several methods and technologies have been developed to automate the process of address and configuration parameter assignment to IPv6 hosts. The various IPv6 address assignment methods are as follows: 1. Manual Assignment An IPv6 address can be statically configured by a human operator. However, manual assignment is quite open to errors and operational overhead due to the 128 bit length and hexadecimal attributes of the addresses, although for router interfaces and static network elements and resources this can be an appropriate solution. 2. Stateless Address Autoconfiguration (RFC2462) Stateless Address Autoconfiguration (SLAAC) is one of the most convenient methods to assign Internet addresses to IPv6 nodes. This method does not require any human intervention at all from an IPv6 user. If one wants to use IPv6 SLAAC on an IPv6 node, it is important that this IPv6 node is connected to a network with at least one IPv6 router connected. This router is configured by the network administrator and sends out Router Advertisement announcements onto the link. These announcements can allow the on-link connected IPv6 nodes to configure themselves with IPv6 address and routing parameters, as specified in RFC2462, without further human intervention. 3. Stateful DHCPv6 The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) has been standardized by the IETF through RFC3315. DHCPv6 enables DHCP servers to pass configuration parameters, such as IPv6 network addresses, to IPv6 nodes. It offers the capability of automatic allocation of reusable network addresses and additional configuration flexibility. This protocol is a stateful counterpart to "IPv6 Stateless Address Autoconfiguration" (RFC 2462), and can be used separately, or in addition to the stateless autoconfiguration to obtain configuration parameters. 4. DHCPv6-PD DHCPv6 Prefix Delegation (DHCPv6-PD) is an extension to DHCPv6, and is specified in RFC3633. Classical DHCPv6 is typically focused upon parameter assignment from a DHCPv6 server to an IPv6 host running a DHCPv6 protocol stack. A practical example would be the stateful address assignment of "2001:db8::1" from a DHCPv6 server to a DHCPv6 client. DHCPv6-PD however is aimed at assigning complete subnets and other network and interface parameters from a DHCPv6-PD server to a DHCPv6-PD client. This means that instead of a single address assignment, DHCPv6-PD will assign a set of IPv6 "subnets". An example could be the assignment of "2001:db8::/60" from a DHCPv6-PD server to a DHCPv6-PD client. This will allow the DHCPv6-PD client (often a CPE device) to segment the received address IPv6 address space, and assign it dynamically to its IPv6 enabled interfaces. 5. Stateless DHCPv6 Stateless DHCPv6 is a combination of "stateless Address Autoconfiguration" and "Dynamic Host Configuration Protocol for IPv6" and is specified by RFC3736. When using stateless-DHCPv6, a device will use Stateless Address Auto-Configuration (SLAAC) to assign one or more IPv6 addresses to an interface, while it utilizes DHCPv6 to receive "additional parameters" which may not be available through SLAAC. For example, additional parameters could include information such as DNS or NTP server addresses, and are provided in a stateless manner by DHCPv6. Using stateless DHCPv6 means that the DHCPv6 server does not need to keep track of any state of assigned IPv6 addresses, and there is no need for state refreshment as result. On network media supporting a large number of hosts associated to a single DHCPv6 server, this could mean a significant reduction in DHCPv6 messages due to the reduced need for address state refreshments. From Cisco IOS 12.4(15)T onwards the client can also receive timing information, in addition to the "additional parameters" through DHCPv6. This timing information provides an indication to a host when it should refresh its DHCPv6 configuration data. This behavior (RFC4242) is particularly useful in unstable environments where changes are likely to occur.
Question 2 of 417

2. Question
What are two requirements for an HSRP group? (Choose two.)
- exactly one active router
- one or more standby routers
- one or more backup virtual routers
- exactly one standby active router
- exactly one backup virtual router
Correct

Incorrect

Hint
http://www.cisco.com/c/en/us/support/docs/ip/hot-standby-router-protocol-hsrp/9234-hsrpguidetoc.html#multihsrp Using HSRP, a set of routers works in concert to present the illusion of a single virtual router to the hosts on the LAN. This set is known as an HSRP group or a standby group. A single router elected from the group is responsible for forwarding the packets that hosts send to the virtual router. This router is known as the Active router. Another router is elected as the Standby router. In the event that the Active router fails, the Standby assumes the packet-forwarding duties of the Active router. Although an arbitrary number of routers may run HSRP, only the Active router forwards the packets sent to the virtual router. To minimize network traffic, only the Active and Standby routers send periodic HSRP messages once the protocol has completed the election process. If the Active router fails, the Standby router takes over as the Active router. If the Standby router fails or becomes the Active router, then another router is elected as the Standby router. On a particular LAN, multiple hot standby groups may coexist and overlap. Each standby group emulates a single virtual router. The individual routers may participate in multiple groups. In this case, the router maintains separate state and timers for each group. Each standby group has a single, well-known MAC address, as well as an IP address.

Hint
http://www.cisco.com/c/dam/en_us/about/ciscoitatwork/downloads/ciscoitatwork/pdf/cisco_it_case_study_multicast.pdf Cisco IOS IP Multicast in the Cisco Network “IP Multicast as defined in RFC1112, the standard for IP Multicast across networks and the Internet, supports one-to-many content needs by delivering application-source traffic to multiple users without burdening the source or the network, using a minimum amount of network bandwidth. At the point where paths diverge, Cisco routers replace IP Multicast packets in the network, resulting in the most efficient delivery of data to multiple receivers.” Even low-bandwidth applications can benefit fro IP Multicast when there are thousands of receivers. High-bandwidth applications, such as MPEG video, may need a large portion of the available network bandwidth for a single stream. In these applications, IP Multicast is the only way to efficiently send the same content to more than one receiver simultaneously, because it makes sure that only one copy of the data stream is sent across any one network link. It relies on each router in the stream to intelligently copy the data stream whenever it needs to deliver it to multiple receivers.

Which two statements about using leased lines for your WAN infrastructure are true? (Choose two.)
- Leased lines provide inexpensive WAN access.
- Leased lines with sufficient bandwidth can avoid latency between endpoints.
- Leased lines require little installation and maintenance expertise.
- Leased lines provide highly flexible bandwidth scaling.
- Multiple leased lines can share a router interface.
- Leased lines support up to T1 link speeds.
Correct

Incorrect

Hint
from W.Odom Official Cert Guide for ICND1 v3 Telcos offer a wide variety of speeds for leased lines. However, you cannot pick the exact speed you want; instead, you must pick from a long list of predefined speeds. Slower-speed links run at multiples of 64 kbps (kilobits per second), while faster links run at multiples of about 1.5 Mbps (megabits per second). Leased lines have many benefits that have led to their relatively long life in the WAN mar- ketplace. These lines are simple for the customer, are widely available, are of high quality, and are private. However, they do have some negatives as well compared to newer WAN technologies, including a higher cost and typically longer lead times to get the service installed.

Hint
Explanation from http://www.9tut.com/trunking-questions Maybe this question wanted to ask “if the other end is configured with trunk/access/desirable mode” then which mode is compatible so that the link can work. In that case both “dynamic auto” and “dynamic desirable” mode are correct. The difference between these two modes is “dynamic auto” is passively waiting for the other end to request to form a trunk while “dynamic desirable” will actively attempt to negotiate to convert the link into a trunk.

What routing protocol use first-hand information from peers?
- link-state
- distance-vector
- path-vector
- other
Correct

Incorrect

Hint
http://www.ciscopress.com/articles/article.asp?p=24090&seqNum=4 The reason is that unlike the routing-by-rumor approach of distance vector, link state routers have firsthand information from all their peer routers. Each router originates information about itself, its directly connected links, and the state of those links (hence the name). This information is passed around from router to router, each router making a copy of it, but never changing it. The ultimate objective is that every router has identical information about the internetwork, and each router will independently calculate its own best paths.

Under normal operations, cisco recommends that you configure switch ports on which vlan?
- on the default vlan
- on the management vlan
- on the native vlan
- on any vlan except the default vlan
Correct

Incorrect

Hint
http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-series-switches/24330-185.html Note: There is a potential security consideration with dot1q that the implicit tagging of the native VLAN causes. The transmission of frames from one VLAN to another without a router can be possible. Refer to the Intrusion Detection FAQ leavingcisco.com for further details. The workaround is to use a VLAN ID for the native VLAN of the trunk that is not used for end-user access. In order to achieve this, the majority of Cisco customers simply leave VLAN 1 as the native VLAN on a trunk and assign access ports to VLANs other than VLAN 1.

As soon as native VLAN is converted back to «1» on SW1, consistency is restored:

Question 230 of 417

At the end of an RSTP election process, which access layer switch port will assume the discarding role?
- Switch3, port fa0/1
- Switch3, port fa0/12
- Switch4, port fa0/11
- Switch4, port fa0/2
- Switch3, port Gi0/1
- Switch3, port Gi0/2
Correct

Incorrect

Hint
In this question, we only care about the Access Layer switches (Switch3 & 4). Switch 3 has a lower bridge ID than Switch 4 (because the MAC of Switch3 is smaller than that of Switch4) so both ports of Switch3 will be in forwarding state. The alternative port will surely belong to Switch4. Switch4 will need to block one of its ports to avoid a bridging loop between the two switches. But how does Switch4 select its blocked port? Well, the answer is based on the BPDUs it receives from Switch3. A BPDU is superior to another if it has: 1. A lower Root Bridge ID 2. A lower path cost to the Root 3. A lower Sending Bridge ID 4. A lower Sending Port ID These four parameters are examined in order. In this specific case, all the BPDUs sent by Switch3 have the same Root Bridge ID, the same path cost to the Root and the same Sending Bridge ID. The only parameter left to select the best one is the Sending Port ID (Port ID = port priority + port index). In this case the port priorities are equal because they use the default value, so Switch4 will compare port index values, which are unique to each port on the switch, and because Fa0/12 is inferior to Fa0/1, Switch4 will select the port connected with Fa0/1 (of Switch3) as its root port and block the other port -> Port fa0/11 of Switch4 will be blocked (discarding role).

Incorrect
Question 236 of 417

236. Question
If router R1 knows a static route to a destination network and then learns about the same destination network through a dynamic routing protocol, how does R1 respond?
- It refuses to advertise the dynamic route to other neighbors
- It sends a withdrawal signal to the neighboring router
- It disables the routing protocol
- It prefers the static route
Correct

Incorrect

Hint
By default the administrative distance of a static route is 1, meaning it will be preferred over all dynamic routing protocols. If you want to have the dynamic routing protocol used and have the static route be used only as a backup, you need to increase the AD of the static route so that it is higher than the dynamic routing protocol.

Question 240 of 417

240. Question
How does a DHCP server dynamically assign IP addresses to hosts?
- Addresses are permanently assigned so that the host uses the same address at all times.
- Addresses are assigned for a fixed period of time.
- Addresses are leased to hosts. A host will usually keep the same address by periodically contacting the DHCP server to renew the lease.
- Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.
Correct

Incorrect

Hint
The DHCP lifecycle consists of the following: Release: The client may decide at any time that it no longer wishes to use the IP address it was assigned, and may terminate the lease, releasing the IP address.

Question 247 of 417

247. Question
When you enable PortFast on a switch port, the port immediately transitions to which state?
- Blocking
- Forwarding
- Learning
- Listening
Correct

Incorrect

Hint
PortFast causes a switch or trunk port to enter the spanning tree forwarding state immediately, bypassing the listening and learning states. You can use PortFast on switch or trunk ports that are connected to a single workstation, switch, or server to allow those devices to connect to the network immediately, instead of waiting for the port to transition from the listening and learning states to the forwarding state.

Question 260 of 417

260. Question
Configuration of which option is required on a Cisco switch for the Cisco IP phone to work?
- PortFast on the interface
- the interface as an access port to allow the voice VLAN ID
- a voice VLAN ID in interface and global configuration mode
- Cisco Discovery Protocol in global configuration mode
Correct

Incorrect

Hint
Configure the Switch Port to Carry Both Voice and Data TrafficWhen you connect an IP phone to a switch using a trunk link, it can cause high CPU utilization in the switches. As all the VLANs for a particular interface are trunked to the phone, it increases the number of STP instances the switch has to manage. This increases the CPU utilization. Trunking also causes unnecessary broadcast / multicast / unknown unicast traffic to hit the phone link. In order to avoid this, remove the trunk configuration and keep the voice and access VLAN configured along with Quality of Service (QoS). Technically, it is still a trunk, but it is called a Multi-VLAN Access Port (MVAP). Because voice and data traffic can travel through the same port, you should specify a different VLAN for each type of traffic. You can configure a switch port to forward voice and data traffic on different VLANs. Configure IP phone ports with a voice VLAN configuration. This configuration creates a pseudo trunk, but does not require you to manually prune the unnecessary VLANs. The voice VLAN feature enables access ports to carry IP voice traffic from an IP phone. The voice VLAN feature is disabled by default. The Port Fast feature is automatically enabled when voice VLAN is configured. When you disable voice VLAN, the Port Fast feature is not automatically disabled

Question 269 of 417

269. Question
When enabled, which feature prevents routing protocols from sending hello messages on an interface?
- virtual links
- passive-interface
- directed neighbors
- OSPF areas
Correct

Incorrect

Hint
You can use the passive-interface command in order to control the advertisement of routing information. The command enables the suppression of routing updates over some interfaces while it allows updates to be exchanged normally over other interfaces. With most routing protocols, the passive-interface command restricts outgoing advertisements only. But, when used with Enhanced Interior Gateway Routing Protocol (EIGRP), the effect is slightly different. This document demonstrates that use of the passive-interface command in EIGRP suppresses the exchange of hello packets between two routers, which results in the loss of their neighbor relationship. This stops not only routing updates from being advertised, but it also suppresses incoming routing updates. This document also discusses the configuration required in order to allow the suppression of outgoing routing updates, while it also allows incoming routing updates to be learned normally from the neighbor

Question 307 of 417

307. Question
What is one benefit of PVST+?
- PVST+ supports Layer 3 load balancing without loops.
- PVST+ reduces the CPU cycles for all the switches in the network.
- PVST+ allows the root switch location to be optimized per VLAN.
- PVST+ automatically selects the root bridge location, to provide optimized bandwidth usage.
Correct

Incorrect

Hint
The PVST+ provides Layer 2 load-balancing for the VLAN on which it runs. You can create different logical topologies by using the VLANs on your network to ensure that all of your links are used but that no one link is oversubscribed. Each instance of PVST+ on a VLAN has a single root switch. This root switch propagates the spanning-tree information associated with that VLAN to all other switches in the network. Because each switch has the same information about the network, this process ensures that the network topology is maintained and optimized per VLAN.
Question 308 of 417

308. Question
Which statement about VLAN operation on Cisco Catalyst switches is true?
- When a packet is received from an 802.1Q trunk, the VLAN ID can be determined from the source MAC address and the MAC address table.
- Unknown unicast frames are retransmitted only to the ports that belong to the same VLAN.
- Broadcast and multicast frames are retransmitted to ports that are configured on different VLAN.
- Ports between switches should be configured in access mode so that VLANs can span across the ports.
Correct

Incorrect

Hint
Each VLAN resides in its own broadcast domain, so incoming frames with unknown destinations are only transmitted to ports that reside in the same VLAN as the incoming frame.
Question 309 of 417

309. Question
Three switches are connected to one another via trunk ports. Assuming the default switch configuration, which switch is elected as the root bridge for the spanning-tree instance of VLAN 1?
- the switch with the highest MAC address
- the switch with the lowest MAC address
- the switch with the highest IP address
- the switch with the lowest IP address
Correct

Incorrect

Hint
Each switch in your network will have a Bridge ID Priority value, more commonly referred to as a BID. This BID is a combination of a default priority value and the switch’s MAC address, with the priority value listed first. The lowest BID will win the election process. For example, if a Cisco switch has the default priority value of 32,768 and a MAC address of 11-22-33- 44-55-66, the BID would be 32768:11-22-33-44-55-66. Therefore, if the switch priority is left at the default, the MAC address is the deciding factor in the root bridge election.

Question 311 of 417

311. Question
Which command can be used from a PC to verify the connectivity between hosts that connect through a switch in the same LAN?
- ping address
- tracert address
- traceroute address
- arp address
Correct

Incorrect

Hint
ICMP pings are used to verify connectivity between two IP hosts. Traceroute is used to verify the router hop path traffic will take but in this case since the hosts are in the same LAN there will be no router hops involved.
Question 312 of 417

312. Question
Refer to the exhibit. Which two statements are true about interVLAN routing in the topology that is shown in the exhibit? (Choose two.)
- Host E and host F use the same IP gateway address.
- Router1 and Switch2 should be connected via a crossover cable.
- Router1 will not play a role in communications between host A and host D.
- The FastEthernet 0/0 interface on Router1 must be configured with subinterfaces.
- Router1 needs more LAN interfaces to accommodate the VLANs that are shown in the exhibit.
- The FastEthernet 0/0 interface on Router1 and the FastEthernet 0/1 interface on Switch2 trunk ports must be configured using the same encapsulation type.
Correct

Incorrect

Hint
In order for multiple VLANs to connect to a single physical interface on a Cisco router, subinterfaces must be used, one for each VLAN. This is known as the router on a stick configuration. Also, for any trunk to be formed, both ends of the trunk must agree on the encapsulation type, so each one must be configured for 802.1q or ISL.
Question 313 of 417

313. Question
What value is primarily used to determine which port becomes the root port on each nonroot switch in a spanning-tree topology?
- path cost
- lowest port MAC address
- VTP revision number
- highest port priority number
- port priority number and MAC address
Correct

Incorrect

Hint
The path cost to the root bridge is the most important value to determine which port will become the root port on each non-root switch. In particular, the port with lowest cost to the root bridge will become root port (on non-root switch).

- IP address utilization will be more efficient.
- More bandwidth will be required than was needed previously.
- An additional broadcast domain will be created.
Correct

Incorrect
Question 318 of 417

318. Question
VLAN 3 is not yet configured on your switch. What happens if you set the switchport access vlan 3 command in interface configuration mode?
- The command is rejected.
- The port turns amber.
- The command is accepted and the respective VLAN is added to vlan.dat.
- The command is accepted and you must configure the VLAN manually.
Correct

Incorrect

Hint
The “switchport access vlan 3″will put that interface as belonging to VLAN 3 while also updated the VLAN database automatically to include VLAN 3.
Question 319 of 417

319. Question
Cisco Catalyst switches CAT1 and CAT2 have a connection between them using ports FA0/13. An 802.1Q trunk is configured between the two switches. On CAT1, VLAN 10 is chosen as native, but on CAT2 the native VLAN is not specified. What will happen in this scenario?
- 802.1Q giants frames could saturate the link.
- VLAN 10 on CAT1 and VLAN 1 on CAT2 will send untagged frames.
- A native VLAN mismatch error message will appear.
- VLAN 10 on CAT1 and VLAN 1 on CAT2 will send tagged frames.
Correct

Incorrect

Hint
A “native VLAN mismatch” error will appear by CDP if there is a native VLAN mismatch on an 802.1Q link. “VLAN mismatch” can cause traffic from one vlan to leak into another vlan.
Question 320 of 417

320. Question
Refer to the exhibit All switch ports are assigned to the correct VLANs, but none of the hosts connected to SwitchA can communicate with hosts in the same VLAN connected to SwitchB. Based on the output shown, what is the most likely problem?
- The access link needs to be configured in multiple VLANs.
- The link between the switches is configured in the wrong VLAN.
- The link between the switches needs to be configured as a trunk.
- VTP is not configured to carry VLAN information between the switches.
- Switch IP addresses must be configured in order for traffic to be forwarded between the switches.
Correct

Incorrect

Hint
In order to pass traffic from VLANs on different switches, the connections between the switches must be configured as trunk ports.
Question 321 of 417

321. Question
What is the function of the command switchport trunk native vlan 999 on a Cisco Catalyst switch?
- It creates a VLAN 999 interface.
- It designates VLAN 999 for untagged traffic.
- It blocks VLAN 999 traffic from passing on the trunk.
- It designates VLAN 999 as the default for all unknown tagged traffic.
Correct

Incorrect

Hint
Configuring the Native VLAN for Untagged Traffic A trunk port configured with 802.1Q tagging can receive both tagged and untagged traffic. By default, the switch forwards untagged traffic in the native VLAN configured for the port. The native VLAN is VLAN 1 by default.
Question 322 of 417

322. Question
Which parameter or parameters are used to calculate OSPF cost in Cisco routers?
- Bandwidth
- Bandwidth and Delay
- Bandwidth, Delay, and MTU
- Bandwidth, MTU, Reliability, Delay, and Load
Correct

Incorrect

Hint
http://www.cisco.com/c/en/us/support/docs/ip/open-shortest-path-first-ospf/7039-1.html#t6 OSPF Cost The cost (also called metric) of an interface in OSPF is an indication of the overhead required to send packets across a certain interface. The cost of an interface is inversely proportional to the bandwidth of that interface. A higher bandwidth indicates a lower cost. There is more overhead (higher cost) and time delays involved in crossing a 56k serial line than crossing a 10M ethernet line. The formula used to calculate the cost is: cost= 10000 0000/bandwith in bps For example, it will cost 10 EXP8/10 EXP7 = 10 to cross a 10M Ethernet line and will cost 10 EXP8/1544000 = 64 to cross a T1 line. By default, the cost of an interface is calculated based on the bandwidth; you can force the cost of an interface with the ip ospf cost interface subconfiguration mode command.

Question 329 of 417

329. Question
Which component of a routing table entry represents the subnet mask?
- Routing protocol code
- Prefix
- metric
- Network mask
Correct

Incorrect

Hint
IP Routing Table Entry Types An entry in the IP routing table contains the following information in the order presented: Network ID. The network ID or destination corresponding to the route. The network ID can be class- based, subnet, or supernet network ID, or an IP address for a host route. Network Mask. The mask that is used to match a destination IP address to the network ID. Next Hop. The IP address of the next hop. Interface. An indication of which network interface is used to forward the IP packet. Metric. A number used to indicate the cost of the route so the best route among possible multiple routes to the same destination can be selected. A common use of the metric is to indicate the number of hops (routers crossed) to the network ID. Routing table entries can be used to store the following types of routes: Directly Attached Network IDs. Routes for network IDs that are directly attached. For directly attached networks, the Next Hop field can be blank or contain the IP address of the interface on that network. Remote Network IDs. Routes for network IDs that are not directly attached but are available across other routers. For remote networks, the Next Hop field is the IP address of a local router in between the forwarding node and the remote network. Host Routes. A route to a specific IP address. Host routes allow routing to occur on a per-IP address ba- sis. For host routes, the network ID is the IP address of the specified host and the network mask is 255.255.255.255. Default Route. The default route is designed to be used when a more specific network ID or host route is not found. The default route network ID is 0.0.0.0 with the network mask of 0.0.0.0.

Incorrect
Question 338 of 417

338. Question
Which two are advantages of static routing when compared to dynamic routing? (Choose two.)
- Configuration complexity decreases as network size increases.
- Security increases because only the network administrator may change the routing table.
- Routing tables adapt automatically to topology changes.
- An efficient algorithm is used to build routing tables, using automatic updates.
- Routing updates are automatically sent to neighbors.
- Routing traffic load is reduced when used in stub network links.
- Route summarization is computed automatically by the router.
Correct

Incorrect

Hint
Explanation: Since static routing is a manual process, it can be argued that it is more secure (and more prone to human errors) since the network administrator will need to make changes to the routing table directly. Also, in stub networks where there is only a single uplink connection, the load is reduced as stub routers just need a single static default route, instead of many routes that all have the same next hop IP address.
Question 339 of 417

339. Question
Refer to the exhibit. Which rule does the DHCP server use when there is an IP address conflict?
- The address is removed from the pool until the conflict is resolved.
- The address remains in the pool until the conflict is resolved.
- Only the IP detected by Gratuitous ARP is removed from the pool.
- Only the IP detected by Ping is removed from the pool.
- The IP will be shown, even after the conflict is resolved.
Correct

Incorrect

Hint
Explanation: An address conflict occurs when two hosts use the same IP address. During address assignment, DHCP checks for conflicts using ping and gratuitous ARP. If a conflict is detected, the address is removed from the pool. The address will not be assigned until the administrator resolves the conflict.
Question 340 of 417

340. Question
Which two tasks does the Dynamic Host Configuration Protocol perform? (Choose two.)
- Set the IP gateway to be used by the network.
- Perform host discovery used DHCPDISCOVER message.
- Configure IP address parameters from DHCP server to a host.
- Provide an easy management of layer 3 devices.
- Monitor IP performance using the DHCP server.
- Assign and renew IP address from the default pool.
Correct

Incorrect

Hint
Explanation: The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP). It involves clients and a server operating in a client-server model. DHCP servers assigns IP addresses from a pool of addresses and also assigns other parameters such as DNS and default gateways to hosts.
