Option D

Suggested answer: A

Explanation:

To prevent loops from occurring accidentally on a switch interface designated for host connectivity, the best practice is to enable Spanning Tree Protocol (STP) protections. Option A, which includes the commandspanning-tree guard loop, is the correct configuration to apply. This command enables Loop Guard, a feature that prevents alternate or root ports from becoming designated ports due to a failure that leads to a unidirectional link. If a port stops receiving Bridge Protocol Data Units (BPDUs), Loop Guard puts the port into an STP loop-inconsistent state, effectively preventing potential loops.
