1. Which statement is true when VTP is configured on a switched network that incorporates VLANs? VTP is only compatible with the 802.1Q standard. VTP adds to the complexity of managing a switched network. VTP allows a switch to be configured to belong to more than one VTP domain. 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.) unable to add VLANs can add VLANs of local significance forward broadcasts out all ports with no respect to VLAN information can only pass VLAN management information without adopting changes can forward VLAN information to other switches in the same VTP domain 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? <!--[if !vml]--> <!--[endif]--> S2 will automatically transition to VTP transparent mode. S2 will remove all VLANs from the VLAN database until the cable is reconnected. S2 will retain the VLANs as of the latest known revision, but will lose the VLANs if it is reloaded. S2 will automatically send a VTP request advertisement to 172.17.99.11 when the cable is reconnected. 4. 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

The lab and production networks use the same VTP domain name. S2 was previously used in a lab environment and has been added to the production network in server mode. so the network administrator made no configuration changes to S2 before adding it to the production network. Which switch or switches receive VTP updates and synchronize their VLAN configuration based on those updates? <!--[if !vml]--> <!--[endif]--> All switches receive updates and synchronize VLAN information. 6. 5. Transparent mode switches do not forward VTP advertisements. This VLAN does not show up on the other switches. What is the reason for this? VLANs cannot be created on transparent mode switches. Only switches SW3 and SW4 receive updates and synchronize VLAN information.dat and change . Only switch SW2 receives updates and synchronizes VLAN information. Refer to the exhibit. Change S1 to transparent VTP mode to reclaim all VLANs in vlan. After S2 was added to the production network. many computers lost network connectivity. except VLAN 1. Each switch is labeled with its VTP mode. What will solve the problem? <!--[if !vml]--> <!--[endif]--> Reset the revision number on S2 with either the delete VTP command or by changing the domain name and then changing it back. VLANs created on transparent mode switches are not included in VTP advertisements. Re-enter all appropriate VLANs. Server mode switches neither listen to nor forward VTP messages from transparent mode switches. Refer to the exhibit. The lab domain has a higher revision number. The switches in the exhibit are connected with trunks within the same VTP management domain. SW3 and SW4 receive updates. manually on Switch1 so that they propagate throughout the network.switch SW3 is configured in VTP transparent mode. A new VLAN is added to Switch3. but only switch SW4 synchronizes VLAN information.

A new host has been attached to a switch in the management domain. What causes a VTP configured switch to issue a summary advertisement? A five-minute update timer has elapsed. The switch is changed to the transparent mode. Change S2 to client mode so the VLANs will automatically propagate. It issues an advertisement request for new VLAN information. 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 suspends forwarding until a subset advertisement update arrives. 9. It issues summary advertisements to advise other switches of status changes. A port on the switch has been shutdown. 8.) Pruning is enabled by default. Which two statements are true about VTP pruning? (Choose two. Which three VTP parameters must be identical on all switches to participate in the same VTP domain? (Choose three. It deletes the VLANs not included in the summary advertisement. Pruning must be configured on all VTP servers in the domain. Pruning can only be configured on VTP servers. 7.back to server mode. It increments the revision number and forwards it to other switches. 10.) revision number domain name pruning mode domain password version number . Pruning will prevent unnecessary flooding of broadcasts across trunks. VLANs on VTP client-mode switches will not be pruned.

what could be done to correct the problem? <!--[if !vml]--> <!--[endif]--> Switch SW2 must be configured as a VTP client. Both switches must be configured with the same VTP revision number. The network administrator issued the show vtp status command to troubleshoot the problem. 13. The switch operates as a VTP server in the default VTP domain and does not effect the configuration in the existing VTP domain. but does not impact the existing VLAN configuration in the domain. Switch2 is in server mode. On the basis of the provided command output. 12. Refer to the exhibit. 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? <!--[if !vml]--> <!--[endif]--> The switch operates as a VTP client. Refer to the exhibit. The switches must be configured with the same VTP domain name. Switch1 is not participating in the VTP management process with the other switches that are shown in the exhibit. The switches must be interconnected via an access link. Switch1 is in a different management domain. The switch operates as a VTP server. Switch2 is in transparent mode. Switches SW1 and SW2 are interconnected via a trunk link but failed to exchange VLAN information. . The switch operates as a VTP server and deletes the existing VLAN configuration in the domain. What are two possible explanations for this? (Choose two. All switches in the network participate in the same VTP domain. The switch operates in VTP transparent mode. Refer to the exhibit.11.) <!--[if !vml]--> <!--[endif]--> Switch1 is in client mode.

15. 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 VTPenabled switches in the same VTP domain. Transparent mode switches can add VLANs of local significance only.) <!--[if !vml]--> <!--[endif]--> If this switch is added to an established network.) Transparent mode switches can create VLAN management information. 16. It verifies the VTP domain name is V1. Refer to the exhibit. It verifies VTP advertisements are being exchanged. . This switch has established two-way communication with the neighboring devices. Which two facts can be confirmed by this output? (Choose two. Transparent mode switches pass any VLAN management information that they receive to other switches. 14. It verifies the VTP domain is configured to use VTP version 2. This switch shows no configuration revision errors. Switch1 is using VTP version 1. This switch is configured to allows the network manager to maximize bandwidth by restricting traffic to specific network devices. and Switch2 is using VTP version 2. Refer to the exhibit. What information can be learned from the output provided? <!--[if !vml]--> <!--[endif]--> It verifies the configured VTP password. Which two statements describe VTP transparent mode operation? (Choose two.Switch1 has end devices that are connected to the ports. Transparent mode switches can adopt VLAN management changes that are received from other switches. Transparent mode switches originate updates about the status of their VLANS and inform other switches about that status.

The VTP password is mandatory and case sensitive. Change the VTP mode to client. What statement describes the default propagation of VLANs on a trunked link? only VLAN 1 all VLANs no VLANs the native VLAN 20. Change the VTP domain name. Change all the interfaces on the switch to access ports. The VTP domain name is case sensitive. Transparent mode switches cannot be configured with new VLANs. 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? Enable VTP pruning.) Switches must be connected via trunks. 18.17. How are VTP messages sent between switches in a domain? Layer 2 broadcast Layer 2 multicast Layer 2 unicast Layer 3 broadcast Layer 3 multicast Layer 3 unicast . Which two statements are true about the implementation of VTP? (Choose two. Switches that use VTP must have the same switch name. 19.
