global unicast. IPv6 questions require identifying the address scope, address block, assignment method, and the role of multicast, link-local, unique-local, or global-unicast addressing. Cisco CCNA 200-301 v1.1 includes this topic under Network Fundamentals, so the answer must be validated against normal Cisco device behavior and the operational wording of the scenario. The key is not simply recognizing a familiar acronym; it is identifying what the feature does, where it is configured, and what result it produces. The wrong choices describe another IPv6 scope or an assignment process that does not match the address behavior in the prompt. In a real network, selecting the wrong option would either leave the feature nonfunctional, create a forwarding or security gap, or send troubleshooting in the wrong direction. The selected answer is the only one that matches the stated requirement and the way Cisco switching, routing, services, security, wireless, or automation functions are expected to operate. This is why the verified answer remains the best technical choice for the question.
