Option B. OSPF operation depends on area membership, network type, timers, router ID, priority, and whether a DR/BDR election occurs. Cisco CCNA 200-301 v1.1 includes this under IP Connectivity, where the expected skill is identifying the mechanism that actually satisfies the scenario. The wording usually gives the decisive clue: a protocol number, a route prefix, a control-plane role, a wireless security method, or a management command. Incorrect choices either use the wrong OSPF role, omit a required adjacency condition, or apply a setting that does not affect the stated behavior. In a real network, selecting the wrong option would usually produce a failed adjacency, broken client connectivity, insecure management access, or an incorrect forwarding path. The selected answer matches the Cisco behavior and configuration model required by the question, so it is retained as the verified answer for this item.
