It is meant to disable any host that is configured to be in VLAN 3.
It is meant to disable any rogue DHCP servers that are attached to VLAN 3.
It is meant to monitor VLAN 3 for DHCP attacks that will deplete the DHCP pool.
It is meant to monitor VLAN 3 and disable any hosts that are using static IP addresses rather than DHCP addresses.

What IOS feature is executed with the traceroute mac command?

Layer 2 traceroute

Embedded Event Manager
Switched Port Analyzer

3. Question

1 points

Which countermeasure can be implemented to determine the validity of an ARP packet, based on the valid MACaddresstoIP address bindings stored in a DHCP snooping database?

DHCP spoofing
dynamic ARP inspection
CAM table inspection
MAC snooping

4. Question

1 points

A network administrator is tasked with protecting a server farm by implementing private VLANs. Each server should only be allowed to communicate with the default gateway. Which type of pVLAN should be configured on the switch port that connects to a server?

isolated
promiscuous
community
secondary VLAN

5. Question

1 points

What can be used to mitigate MAC table flooding attacks?

DHCP snooping
private VLANs
port security
root guard

6. Question

1 points

How does MAC address flooding cause a vulnerability in the network?

The CAM table will be full, causing legitimate frames to be forwarded out all ports within the VLAN and allowing unauthorized users to capture data.
An attacking device can send or receive packets on various VLANs and bypass Layer 3 security measures.
An attacking device can exhaust the address space available to the DHCP servers for a period of time or establish itself as a DHCP server in maninthemiddle attacks.
Information that is sent through CDP is transmitted in clear text and is unauthenticated, allowing it to be captured and to divulge network topology information.

7. Question

1 points

Which type of output would be produced on a switch after entering the command, Switch# show ip dhcp snooping binding?

DHCP servers on the snooped network
DHCP clients on all DHCP snooped switches on the network
DHCP clients that are connected to DHCP snooped ports on the switch
all active protocols on all DHCP clients that are connected to DHCP snooped ports on the switch

8. Question

1 points

What are two purposes for an attacker launching a MAC table flood? (Choose two.)

to initiate a maninthemiddle attack
to initiate a denial of service (DoS) attack
to capture data from the network
to gather network topology information
to exhaust the address space available to the DHCP

9. Question

1 points

How does VLAN hopping cause a vulnerability in the network?

The CAM table will be full, causing legitimate frames to be forwarded out all ports and allowing unauthorized users to capture data.
An attacking device can send or receive packets on various VLANs and bypass Layer 3 security measures.
An attacking device can exhaust the address space available to the DHCP servers for a period of time or establish itself as a DHCP server in maninthemiddle attacks.
Information sent through CDP is transmitted in clear text and is unauthenticated, allowing it to be captured and to divulge network topology information.

10. Question

1 points

What switchport portsecurity keyword causes MAC addresses to be added to the running configuration?

aging
mac-address sticky
maximum
violation

11. Question

1 points

In which location or situation is a private VLAN appropriate?

a DMZ segment
ISP SOHO connections
a web hosting environment at an ISP
two recently merged companies that have overlapping IP addressing schemes

12. Question

1 points

A network administrator is tasked with protecting a server farm by implementing private VLANs (PVLANs). A server is only allowed to communicate with its default gateway and other related servers. Which type of PVLAN should be configured on the switch ports that connect to the servers?

isolated
promiscuous
secondary VLAN
community

13. Question

1 points

Which statement best describes how traffic is handled between different port types within a primary pVLAN?

The traffic is forwarded from promiscuous ports to promiscuous ports in the same primary VLAN.
The traffic is forwarded from promiscuous ports to community and promiscuous ports in the same primary VLAN.
The traffic is forwarded from promiscuous ports to isolated and community ports in the same primary VLAN.
The traffic is forwarded from promiscuous ports to isolated, community, and other promiscuous ports in the same primary VLAN.

14. Question

1 points

What is one way to mitigate spanningtree compromises?

Statically configure the primary and backup root bridge.
Implement private VLANs.
Place all unused ports into a common VLAN (not VLAN 1).
Configure MAC address VLAN access maps.

15. Question

1 points

How should unused ports on a switch be configured in order to prevent VLAN hopping attacks?

Configure them with the UDLD feature.
Configure them with the PAgP protocol.
Configure them as trunk ports for the native VLAN 1.
Configure them as access ports and associate them with an unused VLAN.

16. Question

1 points

What technology can be used to help mitigate MAC address flooding attacks?

root guard
Private VLANs
DHCP snooping
VLAN access maps
Dynamic ARP Inspection

17. Question

1 points

Which configuration guideline applies to using the capture option in VACL?

Capture ports transmit traffic that belongs to all VLANs.
The capture port captures all packets that are received on the port.
The switch has a restriction on the number of capture ports.
The capture port needs to be in the spanningtree forwarding state for the VLAN.

18. Question

1 points

All access ports on a switch are configured with the administrative mode of dynamic auto. An attacker, connected to one of the ports, sends a malicious DTP frame. What is the intent of the attacker?

VLAN hopping
DHCP spoofing attack
MAC flooding attack
ARP poisoning attack

19. Question

1 points

Refer to the exhibit. After the configuration has been applied to ACSw22, frames that are bound for the node on port FastEthernet 0/1 are periodically being dropped. What should be done to correct the issue?

Add the switchport portsecurity mac-address sticky command to the interface configuration.
Change the port speed to speed auto with the interface configuration mode.
Use the switchport mode trunk command in the interface configuration.
Remove the switchport command from the interface configuration.

20. Question

1 points

What is one way to mitigate ARP spoofing?

Enable dynamic ARP inspection.
Configure MAC address VLAN access maps.
Enable root guard.
Implement private VLANs.
