Use C for this item. Cloud-based topology delivers services through public, private, or hybrid cloud deployment models. The defining characteristic is that compute, storage, applications, or network services are consumed from cloud infrastructure rather than only local physical equipment. In Cisco CCNA 200-301 v1.1, Network Fundamentals questions frequently test the practical boundary between similar features: what the feature does, where it is configured, and what problem it is meant to solve. Wireless access is not the sole method, and on-site Layer 2/Layer 3 components describe local infrastructure rather than cloud topology. A clean way to validate the answer is to map the wording of the scenario to the actual device function. If the feature supplies addressing, forwarding, authentication, trunking, route selection, or controller communication, the answer must match that function exactly rather than a nearby protocol name.
