C. Configure a SPAN session to monitor the received traffic on interface g0/5 only for VLAN 3.

D. Configure a SPAN session to monitor the received traffic on interface g0/5 for all VLANs except VLAN 3.

Answer: A

Q2. Refer to the exhibit.

How can the traffic that is mirrored out the GigabitEthernet0/48 port be limited to only traffic that is received or transmitted in VLAN 10 on the GigabitEthernet0/1 port?

A. Change the configuration for GigabitEthernet0/48 so that it is a member of VLAN 10.

B. Add an access list to GigabitEthernet0/48 to filter out traffic that is not in VLAN 10.

C. Apply the monitor session filter globally to allow only traffic from VLAN 10.

Answer: C

Q3. Which VRRP router is responsible for forwarding packets that are sent to the IP addresses of the virtual router?

A. virtual router master

B. virtual router backup

C. virtual router active

D. virtual router standby

Answer: A

Q4. Refer to the exhibit.

A network engineer investigates a recent network failure and notices that one of the interfaces on the switch is still down. What is causing the line protocol on this interface to be shown as down?

A. There is a layer 1 physical issue.

B. There is a speed mismatch on the interface.

C. The interface is configured as the target of the SPAN session.

D. The interface is configured as the source of the SPAN session.

E. There is a duplex mismatch on the interface.

Answer: C

Q5. A network engineer must improve bandwidth and resource utilization on the switches by stopping the inefficient flooding of frames on trunk ports where the frames are not needed. Which Cisco IOS feature can be used to achieve this task?

A. VTP pruning

B. access list

C. switchport trunk allowed VLAN

D. VLAN access-map

Answer: A

Q6. After implementing VTP, the extended VLANs are not being propagated to other VTP switches. What should be configured for extended VLANs?

A. VTP does not support extended VLANs and should be manually added to all switches.

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
