F. switchport vlan native trunk 99

Answer :

Final answer:

The correct option to set VLAN 99 as the native VLAN on a trunk is A. `switch port trunk native vlan 99`.

Explanation:

To set VLAN 99 as the native configuration VLAN on a trunk in a Cisco switch, you would use the command: switch port trunk native vlan 99. This command sets the native VLAN (untagged VLAN) on a trunk link to VLAN 99.

When a switch receives an untagged frame on a trunk link, it associates the frame with the native VLAN. By default, the native VLAN is VLAN 1, but the above command changes it to VLAN 99.

Let's understand it with an example. If Switch A sends a frame on VLAN 99 (which is the native VLAN) to Switch B over a trunk link, Switch A does not tag the frame.

When Switch B receives this untagged frame, it associates it with its own native VLAN. Therefore, it becomes crucial that both sides of the trunk link agree on the native VLAN.
