DLS1 is connected to another switch, DLS2, via a trunk link. A host that is connected to DLS1 is not able to communicate to a host that is connected to DLS2, even though they are both in VLAN 99. Which command should be added to Fa0/1 on DLS1 to correct the problem

Switchport does not compromise, switch auto dynamic mode, switch native vlan 66, default swamp vlan enabled to add 99 is the correct answer of the following question.

Explanation:

As configuring 802.1Q warp links, DLS1 is connected to the next switch, DLS2, via a diffusion connection to the local VLAN, that must match on the both sides of the wire, either CDP error signals will be created and data to or from the the original VLAN will not be managed properly.Such instruction must be extended to Fa0/1 on DLS1 to address issues that can not be communicated by a server related to DLS1 to a network tied to DLS1, even though both are in VLAN 99.
