Question 990
A branch design for Granite Works has two requirements: (1) confirm which VLANs are actively forwarded over a trunk, and (2) avoid a user access port automatically forming an unintended trunk. Select TWO actions that together satisfy both outcomes.
Explanation
Correct Answers
Correct for outcome (1): The command displays operational trunks, encapsulation/native VLAN and allowed/active VLANs. The other outcome needs its separate action.
Correct for outcome (2): Access mode prevents the interface from carrying multiple data VLANs as a negotiated trunk. It complements the first required control.
Incorrect Answers
Not selected: Configure trunk and allowed VLANs on the port-channel interface is for keep an aggregated trunk's VLAN policy consistent. The logical port-channel is the switching interface whose member ports must have compatible settings. This does not provide either of the two specified controls.
Not selected: Enable Loop Guard on eligible non-designated spanning-tree links is for avoid a blocked STP link unexpectedly forwarding after BPDUs disappear. Loop Guard can hold a port in loop-inconsistent state when BPDUs cease unexpectedly. This is outside the two requested outcomes.
Not selected: Use a supported autonomous AP mode or small-business AP is for deploy standalone wireless connectivity at a tiny site without a central WLC. An autonomous or locally managed AP does not depend on a separate enterprise WLC for all management. This is not one of the two required changes.
