R3(config)#interface Gig0/0 R3(config-if)#ip ospf priority 100. OSPF behavior is controlled by interface state, area, timers, network type, cost, priority, router ID, and neighbor/adjacency rules. Cisco CCNA 200-301 v1.1 includes this under IP Connectivity, where the exam expects engineers to recognize the device behavior that actually produces the required outcome. The question is best solved by reading the operational clue rather than choosing a familiar acronym. The distractors confuse OSPF with unrelated metrics, local-only process values, or parameters that do not satisfy the adjacency or route-selection requirement. In a production network, the wrong choice would normally create an outage, leave a management or security gap, or send troubleshooting toward the wrong subsystem. The selected answer is the one that matches the control-plane, data-plane, wireless, security, services, or automation mechanism described in the question. That is why it remains the verified answer for this item.

TACACS+. TACACS+ separates the authentication, authorization, and accounting functions, which makes it suitable when an administrator wants distinct control over identity verification and permitted actions. RADIUS combines authentication and authorization more tightly and is widely used for network access authentication, especially wireless clients, but it is not the protocol known for separating those functions. 802.1X is an access-control framework and Kerberos is a ticket-based authentication system. Cisco CCNA 200-301 v1.1 Security Fundamentals expects engineers to know the operational difference between RADIUS and TACACS+. Because the question specifically calls out separate authorization and authentication, the corrected answer is TACACS+. That separation gives administrators more granular control over administrative access and device configuration authorization.

10.129.9.0/2310.139.2.0/3010.2.191.0/3010.129.9.0/25. Cisco routing logic is deterministic: a router first matches the most specific destination prefix, then uses administrative distance when competing route sources advertise the same prefix, and finally evaluates the protocol metric when multiple paths remain inside the same routing protocol. First-hop redundancy protocols add a separate default-gateway resiliency function for hosts on a LAN. The other choices in this question either point to the wrong route-selection rule, confuse a protocol metric with administrative distance, or apply a Layer 2 concept where a Layer 3 forwarding decision is required. In production, that mistake would create blackholing, asymmetric routing, or a backup path that never activates. Cisco CCNA 200-301 v1.1 tests this because route selection is fundamental to troubleshooting reachability. The selected answer matches the behavior Cisco routers use when forwarding traffic or maintaining gateway redundancy.
