Question

What is a characteristic of a WAN hub-and-spoke topology? It requires that some of the branch sites be interconnected through point-to-point links. It requires that every site be interconnected to each other through point-to-point links. All sites require a hub device that connects to a router. The branch sites are connected to a central site through point-to-point links.​

Answer 1

Answer: The branch sites are connected to a central site through point-to-point links.​

Explanation: WAN(Wide area network) has a topology scheme in the form of hub and spoke that contains a hub as the central point for the and other nodes in the network behave as spoke.

Wide area network is the network that is collection of the MANs(Metropolitan area network) and LANs (Local area network) .This network is spread over a large geographical area having point to point connection between nodes and central hub.

Other options are incorrect because some branches are not in point to point connection rather all branches persist this connection with hub.All sites do not require hub to connect with router as it is centrally attached with hub.
