CCNA v4 - E3 - Module 4 (100%)

1. Which statement is true when VTP is configured on a switched network that incorporates VLANs?

VTP dynamically communicates VLAN changes to all switches in the same VTP domain.

What are two features of VTP client mode operation? (Choose two.)

unable to add VLANs
can forward VLAN information to other switches in the same VTP domain

3. Which three VTP parameters must be identical on all switches to participate in the same VTP domain? (Choose three.)

domain name
domain password
version number

4. What does a client mode switch in a VTP management domain do when it receives a summary advertisement with a revision number higher than its current revision number?

It issues an advertisement request for new VLAN information.

5. Refer to the exhibit. The switches in the exhibit are connected with trunks within the same VTP management domain. Each switch is labeled with its VTP mode. A new VLAN is added to Switch3. This VLAN does not show up on the other switches. What is the reason for this?

VLANs created on transparent mode switches are not included in VTP advertisements.

6. Refer to the exhibit. S2 was previously used in a lab environment and has been added to the production network in server mode. The lab and production networks use the same VTP domain name, so the network administrator made no configuration changes to S2 before adding it to the production network. The lab domain has a higher revision number. After S2 was added to the production network, many computers lost network connectivity. What will solve the problem?

Re-enter all appropriate VLANs, except VLAN 1, manually on Switch1 so that they propagate throughout the network.

7. Which two statements describe VTP transparent mode operation? (Choose two.)

Transparent mode switches can add VLANs of local significance only.
Transparent mode switches pass any VLAN management information that they receive to other switches.

8. What causes a VTP configured switch to issue a summary advertisement?

A five-minute update timer has elapsed.

9. What statement describes the default propagation of VLANs on a trunked link?

all VLANs

10. Refer to the exhibit. All switches in the VTP domain are new. Switch SW1 is configured as a VTP server, switches SW2 and SW4 are configured as VTP clients, and switch SW3 is configured in VTP transparent mode. Which switch or switches receive VTP updates and synchronize their VLAN configuration based on those updates?

SW3 and SW4 receive updates, but only switch SW4 synchronizes VLAN information.

11. Refer to the exhibit. All switches in the network participate in the same VTP domain. What happens when the new switch SW2 with a default configuration and revision number of 0 is inserted in the existing VTP domain Lab_Network?

The switch operates as a VTP server, but does not impact the existing VLAN configuration in the domain.

12. Refer to the exhibit. Switches SW1 and SW2 are interconnected via a trunk link but failed to exchange VLAN information. The network administrator issued the show vtp status command to troubleshoot the problem. On the basis of the provided command output, what could be done to correct the problem?

The switches must be configured with the same VTP domain name.

13. Refer to the exhibit. Switch1 is not participating in the VTP management process with the other switches that are shown in the exhibit. What are two possible explanations for this? (Choose two.)

Switch1 is in a different management domain.
Switch1 is using VTP version 1, and Switch2 is using VTP version 2.

14. How are VTP messages sent between switches in a domain?

Layer 2 multicast

15. Refer to the exhibit. Which two facts can be confirmed by this output? (Choose two.)

If this switch is added to an established network, the other VTP-enabled switches in the same VTP domain will consider their own VLAN information to be more recent than the VLAN information advertised by this switch.
This switch is configured to advertise its VLAN configuration to other VTP-enabled switches in the same VTP domain.

16. Which two statements are true about VTP pruning? (Choose two.)

Pruning can only be configured on VTP servers.
Pruning will prevent unnecessary flooding of broadcasts across trunks.

17. Refer to the exhibit. What information can be learned from the output provided?

It verifies VTP advertisements are being exchanged.

18. A network administrator is replacing a failed switch with a switch that was previously on the network. What precautionary step should the administrator take on the replacement switch to avoid incorrect VLAN information from propagating through the network?

Change the VTP domain name.

19. Which two statements are true about the implementation of VTP? (Choose two.)

Switches must be connected via trunks.
The VTP domain name is case sensitive.

20. Refer to the exhibit. Switch S1 is in VTP server mode. Switches S2 and S3 are in client mode. An administrator accidentally disconnects the cable from F0/1 on S2. What will the effect be on S2?

S2 will retain the VLANs as of the latest known revision, but will lose the VLANs if it is reloaded.
