Option B. Switching questions depend on MAC learning, VLAN membership, trunking, STP election, and EtherChannel behavior. Cisco CCNA 200-301 v1.1 includes this under Security Fundamentals, where the expected skill is selecting the feature that actually produces the requested network behavior. The wording normally gives the clue: protocol family, address scope, trunk state, route preference, security mode, API method, or controller role. Wrong answers misapply a Layer 2 rule or configure the wrong logical interface. In production, choosing the wrong option would typically cause failed client access, a broken route, insecure management, or an automation workflow that targets the wrong interface. The selected answer is the Cisco-consistent behavior for this item.
