VTP Questions 3
Here you will find answers to VTP Questions – Part 3
Question 1
Which two statements correctly describe VTP? (Choose two)
A. Transparent mode always has a configuration revision number of 0.
B. Transparent mode cannot modify a VLAN database.
C. Client mode cannot forward received VTP advertisements.
D. Client mode synchronizes its VLAN database from VTP advertisements.
E. Server mode can synchronize across VTP domains.
Answer: A D
Explanation
When setting a switch to Transparent mode, the switch’s configuration revision number is automatically reset to 0 -> A is correct.
Not only client mode but server mode synchronize its VLAN database from VTP advertisements -> D is correct.
Question 2
The network administrator needs to enable VTP pruning within the network. What action should a network administrator take to enable VTP pruning on an entire management domain?
A – enable VTP pruning on every switch in the domain
B – enable VTP pruning on any client switch in the domain
C – enable VTP pruning on any switch in the management domain
D – enable VTP pruning on a VTP server in the management domain
Answer: D
Question 3
The network operations center has received a call stating that Users in VLAN 107 are unable to access resources through R1. From the information contained in the graphic, what is the cause of this problem?
A – spanning tree is not enabled on VLAN 107
B – VTP is pruning VLAN 107
C – VLAN 107 does not exist on switch SA
D – VLAN 107 is not configured on the trunk
Answer: B
Explanation:
“VLAN allowed on trunk” – Each trunk allows all VLANs by default. However, administrator can remove or add to the list by using the “switchport trunk allowed” command.
“VLANs allowed and active in management” – To be active, a VLAN must be in this list.
“VLANs in spanning tree forwarding state and not pruned” – This list is a subset of the “allowed and active” list but with any VTP-pruned VLANs removed.
All VLANs were configured except VLAN 101 so D is not correct. VLAN 107 exists in the “allowed and active” section so A and C are not correct, too. In the “forwarding state and not pruned” we don’t see VLAN 107 so the administrator had wrongly configured this VLAN as pruned.
