Refer to the exhibit. PC-A and PC-B are both in VLAN 60. PC-A is unable to communicate with PC-B. What is the problem?
- The native VLAN should be VLAN 60.
- The native VLAN is being pruned from the link.
- The trunk has been configured with the switchport nonegotiate command.
- The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk.
Answers Explanation & Hints: Because PC-A and PC-B are connected to different switches, traffic between them must flow over the trunk link. Trunks can be configured so that they only allow traffic for particular VLANs to cross the link. In this scenario, VLAN 60, the VLAN that is associated with PC-A and PC-B, has not been allowed across the link, as shown by the output of show interfaces trunk .
