Question 1Several new switches have been added to the existing network as VTP clients. All of the new switches have been configured with the same VTP domain, password, and version. However, VLANs are not passing from the VTP server (existing network) to the VTP clients. What must be done to fix this?
A. Remove the VTP domain name from all switches with “null” and then replace it with the new domain name.
B. Configure a different native VLAN on all new switches that are configured as VTP clients.
C. Provision one of the new switches to be the VTP server and duplicate information from the existing network.
D. Ensure that all switch interconnects are configured as trunks to allow VTP information to be transferred.
Answer: D
Explanation
VTP updates can only be forwarded on trunk links.
Question 2After 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
Explanation
VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.
Question 3Which technique automatically limits VLAN traffic to only the switches that require it?
A. access lists
B. DTP in nonegotiate
C. VTP pruning
D. PBR
Answer: C
Explanation
VTP Pruning makes more efficient use of trunk bandwidth by forwarding broadcast and unknown unicast frames on a VLAN only if the switch on the receiving end of the trunk has ports in that VLAN. In the below example, Server switch doesn’t send broadcast frame to Sw2 because Sw2 doesn’t have ports in VLAN 10.
Question 4Refer to the exhibit.
Switch A, B, and C are trunked together and have been properly configured for VTP. Switch C receives VLAN information from the VTP server Switch A, but Switch B does not receive any VLAN information. What is the most probable cause of this behavior?
A. Switch B is configured in transparent mode.
B. Switch B is configured with an access port to Switch A, while Switch C is configured with a trunk port to Switch B.
C. The VTP revision number of the Switch B is higher than that of Switch A.
D. The trunk between Switch A and Switch B is misconfigured.
Answer: A
Explanation
Switch C can receive VLAN information from Switch A so Switch B can forward it to Switch C without updating its VLAN database -> Switch B is in VTP transparent mode.
Question 5A network is running VTPv2. After verifying all VTP settings, the network engineer notices that the new switch is not receiving the list of VLANs from the server. Which action resolves this problem?
A. Reload the new switch.
B. Restart the VTP process on the new switch.
C. Reload the VTP server.
D. Verify connected trunk ports.
Answer: D
Explanation
VTP updates can only be forwarded on trunk links.
Question 6After configuring new data VLANs 1020 through 1030 on the VTP server, a network engineer notices that none of the VTP clients are receiving the updates. What is the problem?
A. The VTP server must be reloaded.
B. The VTP version number must be set to version 3.
C. After each update to the VTP server, it takes up to 4 hours propagate.
D. VTP must be stopped and restarted on the server.
E. Another switch in the domain has a higher revision number than the server.
Answer: B
Explanation
VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.
Question 7A network engineer is extending a LAN segment between two geographically separated data centers. Which enhancement to a spanning-tree design prevents unnecessary traffic from crossing the extended LAN segment?
A. Modify the spanning-tree priorities to dictate the traffic flow.
B. Create a Layer 3 transit VLAN to segment the traffic between the sites.
C. Use VTP pruning on the trunk interfaces.
D. Configure manual trunk pruning between the two locations.
Answer: C
Explanation
VTP Pruning makes more efficient use of trunk bandwidth by forwarding broadcast and unknown unicast frames on a VLAN only if the switch on the receiving end of the trunk has ports in that VLAN
Question 8When you design a switched network using VTPv2, how many VLANs can be used to carry user traffic?
A. 1000
B. 1001
C. 1024
D. 2048
E. 4095
F. 4096
Answer: B
Explanation
VTP version 1 and version 2 support VLANs 1 to 1000 only. Extended-range VLANs are supported only in VTP version 3. If converting from VTP version 3 to VTP version 2, VLANs in the range 1006 to 4094 are removed from VTP control.
Question 9A new network that consists of several switches has been connected together via trunking interfaces. If all switches currently have the default VTP domain name “null”, which statement describes what happens when a domain name is configured on one of the switches?
A. The switch with the non-default domain name restores back to “null” upon reboot.
B. Switches with higher revision numbers does not accept the new domain name.
C. VTP summary advertisements are sent out of all ports with the new domain name.
D. All other switches with the default domain name become VTP clients.
Answer: C
Explanation
If a VTP client or server with a null domain receives a VTP message with the domain populated, it will assume the domain of the received message and add applicable VLANs to its database.
Question 10Which VTP mode is needed to configure an extended VLAN, when a switch is configured to use VTP versions 1 or 2?
A. transparent
B. client
C. server
D. Extended VLANs are only supported in version 3 and not in versions 1 or 2.
Answer: A
Explanation
With VTP version 1 and version 2, when the switch is in VTP transparent mode (VTP disabled), you can create extended-range VLANs (in the range 1006 to 4094)
