A client experiences slow throughput from a server that is directly connected to the core...

a physical cable fault. IP services questions require matching the protocol or service to its exact role in monitoring, addressing, traffic treatment, or application access. Cisco CCNA 200-301 v1.1 includes this under Network 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. The wrong choices name real services but solve a different operational problem. 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.
