Cisco 300-115 Online Questions & Answers

• Question 361:

  Refer to the exhibit.

  

  Switch A, B, and C are trunked together and have been properly configured for VTP. Switch B has all VLANs, but Switch C is not receiving traffic from certain VLANs. What would cause this issue?

  A. A VTP authentication mismatch occurred between Switch A and Switch B.
  B. The VTP revision number of Switch B is higher than that of Switch A.
  C. VTP pruning is configured globally on all switches and it removed VLANs from the trunk interface that is connected to Switch C.
  D. The trunk between Switch A and Switch B is misconfigured.
  C. VTP pruning is configured globally on all switches and it removed VLANs from the trunk interface that is connected to Switch C.

  VTP pruning increases network available bandwidth by restricting flooded traffic to those trunk links that the traffic must use to reach the destination devices. Without VTP pruning, a switch floods broadcast, multicast, and unknown unicast traffic across all trunk links within a VTP domain even though receiving switches might discard them. VTP pruning is disabled by default. VTP pruning blocks unneeded flooded traffic to VLANs on trunk ports that are included in the pruning-eligible list. The best explanation for why switch C is not seeing traffic from only some of the VLANs, is that VTP pruning has been configured.
