Question 920
Two Cisco switches have VLAN 10 and VLAN 20 configured. Gi1/0/48 is administratively set to access mode on one end and trunk mode on the other, and only VLAN 10 communication works. What is the primary correction for carrying both VLANs over this link?
Explanation
Correct Answer
A port operating as access cannot carry two separate tagged client VLANs; the link must be consistently trunked.
Incorrect Answers
A native-VLAN setting does not make an access-mode port carry multiple tagged VLANs.
Routing entries cannot substitute for a correctly configured multi-VLAN Layer 2 uplink.
Removing VLAN 20 prevents the required VLAN from traversing the trunk.
