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

1 VTP is only compatible with the 802.1Q standard.
2 VTP adds to the complexity of managing a switched network.
3 VTP allows a switch to be configured to belong to more than one VTP domain.
4 VTP dynamically communicates VLAN changes to all switches in the same VTP domain.

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

1 unable to add VLANs
2 can add VLANs of local significance
3 forward broadcasts out all ports with no respect to VLAN information
4 can only pass VLAN management information without adopting changes

* 4.1.1 What is VTP?

3

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?
1 S2 will retain the VLANs as of the latest known revision.
2 S2 will automatically transition to VTP transparent mode.
3 S2 will remove all VLANs from the VLAN database until the cable is reconnected.
4 S2 will automatically send a VTP request advertisement to 172.17.99.11 when the cable is
reconnected.

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?

1 All switches receive updates and synchronize VLAN information.
2 Only switch SW2 receives updates and synchronizes VLAN information.
3 Only switches SW3 and SW4 receive updates and synchronize VLAN information.
4 SW3 and SW4 receive updates, but only switch SW4 synchronizes VLAN information.

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?

1 VLANs cannot be created on transparent mode switches.
2 Transparent mode switches do not forward VTP advertisements.
3 VLANs created on transparent mode switches are not included in VTP advertisements.
4 Server mode switches neither listen to nor forward VTP messages from transparent mode
switches.

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?

1 Reset the revision number on S2 with either the delete VTP command or by changing the domain
name and then changing it back.
2 Re-enter all appropriate VLANs, except VLAN 1, manually on Switch1 so that they propagate
throughout the network.
3 Change S1 to transparent VTP mode to reclaim all VLANs in vlan.dat and change back to server
mode.
4 Change S2 to client mode so the VLANs will automatically propagate.

7 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?
1 It suspends forwarding until a subset advertisement update arrives.
2 It issues an advertisement request for new VLAN information.
3 It increments the revision number and forwards it to other switches.
4 It deletes the VLANs not included in the summary advertisement.
5 It issues summary advertisements to advise other switches of status changes.

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

1 A five-minute update timer has elapsed.
2 A port on the switch has been shutdown.
3 The switch is changed to the transparent mode.
4 A new host has been attached to a switch in the management domain.

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

1 Pruning is enabled by default.
2 Pruning can only be configured on VTP servers.
3 Pruning must be configured on all VTP servers in the domain.
4 VLANs on VTP client-mode switches will not be pruned.
5 Pruning will prevent unnecessary flooding of broadcasts across trunks.

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

2 domain name
3 pruning

6 version number

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?

1 The switch operates as a VTP client.
2 The switch operates in VTP transparent mode.
3 The switch operates as a VTP server and deletes the existing VLAN configuration in the domain.
4 The switch operates as a VTP server, but does not impact the existing VLAN configuration in the
domain.
5 The switch operates as a VTP server in the default VTP domain and does not affect the
configuration in the existing VTP 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?
1 Switch SW2 must be configured as a VTP client.
2 The switches must be interconnected via an access link.
3 The switches must be configured with the same VTP domain name.
4 Both switches must be configured with the same VTP revision number.
