A. allowed VLAN list
B. VTP pruning
C. VACL
D. L2P tunneling
Answer: A
Q9. Refer to the exhibit.
The users in an engineering department that connect to the same access switch cannot access the network. The network engineer found that the engineering VLAN is missing from the database. Which action resolves this problem?
A. Disable VTP pruning and disable 802.1q.
B. Update the VTP revision number.
C. Change VTP mode to server and enable 802.1q.
D. Enable VTP pruning and disable 802.1q.
Answer: C
Q10. Refer to the exhibit.
What is the result of the configuration?
A. The EtherChannels would not form because the load-balancing method must match on the devices.
B. The EtherChannels would form and function properly even though the load-balancing and EtherChannel modes do not match.
C. The EtherChannels would form, but network loops would occur because the load- balancing methods do not match.
D. The EtherChannels would form and both devices would use the dst-ip load-balancing method because Switch1 is configured with EtherChannel mode active.
Answer: B
Q11. Which statement describes what happens if all VSL connections between the virtual switch
members are lost?
A. Both virtual switch members cease to forward traffic.
B. The VSS transitions to the dual active recovery mode, and both virtual switch members continue to forward traffic independently.
C. The virtual switch members reload.
D. The VSS transitions to the dual active recovery mode, and only the new active virtual switch continues to forward traffic.
Answer: D
Q12. RSPAN has been configured on a Cisco Catalyst switch; however, traffic is not being replicated to the remote switch. Which type of misconfiguration is a cause?
A. The RSPAN designated VLAN is missing the remote span command.
B. The local and remote RSPAN switches are configured using different session IDs.
C. The local RSPAN switch is replicating only Rx traffic to the remote switch.
D. The local switch is overloaded with the amount of sourced traffic that must be replicated to the remote switch.
Answer: A
Q13. Which SDM template is the most appropriate for a Layer 2 switch that provides connectivity to a large number of clients?
A. VLAN
B. default
C. access
D. routing
Answer: A
Q14. The network manager has requested that several new VLANs (VLAN 10, 20, and 30) are allowed to traverse the switch trunk interface. After the command switchport trunk allowed vlan 10,20,30 is issued, all other existing VLANs no longer pass traffic over the trunk. What is the root cause of the problem?
A. The command effectively removed all other working VLANs and replaced them with the new VLANs.
B. VTP pruning removed all unused VLANs.
C. ISL was unable to encapsulate more than the already permitted VLANs across the trunk.
D. Allowing additional VLANs across the trunk introduced a loop in the network.
Answer: A

C. spanning-tree portfast bpdufilter default
D. no spanning-tree link-type shared
Answer: C
Q16. After an EtherChannel is configured between two Cisco switches, interface port channel 1 is in the down/down state. Switch A is configured with channel-group 1 mode active, while Switch B is configured with channel-group 1 mode desirable. Why is the EtherChannel bundle not working?
A. The switches are using mismatched EtherChannel negotiation modes.
B. The switch ports are not configured in trunking mode.
C. LACP priority must be configured on both switches.
D. The channel group identifier must be different for Switch A and Switch B.
Answer: A
Q17. After implementing VTP, the extended VLANs are not being propagated to other VTP switches. What should be configured for extended VLANs?

B. Enable VTP version 3, which supports extended VLAN propagation.
C. VTP authentication is required when using extended VLANs because of their ability to cause network instability.
D. Ensure that all switches run the same Cisco IOS version. Extended VLANs will not propagate to different IOS versions when extended VLANs are in use.
Answer: B
