Final answer:
WAN topologies include full mesh (each location directly connected to others), hub-and-spoke (one main location with remote networks), point-to-point (single pre-established path), redundant link (two connections to a single ISP), and single-link (one line to ISP).
Step-by-step explanation:
The WAN topologies mentioned correspond with specific network designs.
The topology that connects multiple network locations via WAN links with each location having a direct link to all other locations is known as a full mesh topology. It’s a robust setup but can be expensive due to the number of links required.
When multiple remote networks are connected via WAN links with one site acting as the main location, this refers to a hub-and-spoke topology. Here, the 'hub' is the central node to which all 'spokes' or remote networks are connected.
A network topology featuring a single, pre-established path from one location through a carrier network to a remote network location is called a point-to-point topology. It's a simple, dedicated line between two locations.
The topology that provides two separate physical connections to a single ISP for redundancy is known as a redundant link topology.
Lastly, a network connected to an ISP using a single line typically refers to a single-link topology, which is a simple and common setup for small networks.
