Question 28

Question
The network manager has requested that several new VLANs (VLAN 10, 20, 30) are allowed to traverse the switch trunk interface. After the command switchport trunk allowed vlan 10,20,30 is issued, all other existing VLANs no longer pass traffic over the trunk. What is the root cause of the problem?
Answer
  • VTP pruning removed all unused VLANs

  • All interfaces are shut down in the formerly active virtual switch member but the new active virtual switch forwards traffic on all links.
  • The switch continues to forward traffic out all links and enables spanning tree on VSL links and all other links to prevent loops.

Question 40

Question

Answer
  • Change the monitor session source VLAN 10 instead of the physical interface
  • Add an access list to GiE0/48 to filter out traffic that is not in VLAN 10
  • Apply the monitor session filter globally to allow only traffic from VLAN 10
  • Change the configuration for GiE0/48 so that it is a member of VLAN 10
