Option D. Switching questions depend on MAC learning, VLAN membership, trunking, EtherChannel behavior, STP roles, and port-security rules. Cisco CCNA 200-301 v1.1 includes this under Network Access, where the expected skill is to identify the feature that actually creates the observed behavior or meets the configuration goal. The wording usually contains the decisive clue: a prefix length, a VLAN role, a protocol version, a wireless security standard, or a management-plane function. Wrong answers either cross VLAN boundaries incorrectly, misread STP election logic, or apply a control to the wrong interface state. In an operational network, choosing the wrong option would typically cause failed connectivity, insecure management, poor wireless behavior, or incorrect forwarding. The selected answer matches the Cisco configuration model and is retained as the verified answer.
