You have just configured a trunk between two switches, Switch A and Switch B. The trunk operates as normal. However, there are minor issues with some of the switch traffic. What might be the problem? Refer to the following exhibit.

A. Switch A is pruning all VLANs except for VLAN 1.
B. The switches are on incompatible links.
C. Switch B has an inactive native VLAN.
D. Both switches have a native VLAN mismatch.

D. Both switches have a native VLAN mismatch. Since Switch B has an inactive VLAN, it would be recommended to change the native VLAN back to 1 on Switch B.
