Why each option
A router is the correct device for connecting two geographically separate network sites because it operates at Layer 3 and routes packets between different networks across WAN links.
A switch operates at OSI Layer 2 and forwards frames within a single LAN segment based on MAC addresses; it cannot route traffic between remote sites.
An access point provides wireless connectivity within a local area and cannot bridge geographically separate sites over a WAN.
Routers operate at OSI Layer 3 (Network layer) and make forwarding decisions based on IP addresses, enabling them to connect distinct networks - including remote sites - over WAN technologies such as leased lines, MPLS, or VPNs. They maintain routing tables and determine the best path for traffic between the two locations.
A hub is a Layer 1 device that simply broadcasts incoming signals to all ports within a single LAN and has no routing capability.
