Direct Connection WAN Topology

B

The correct answer is B. full mesh.

A Wide Area Network (WAN) is a type of computer network that spans across a large geographical area, connecting multiple Local Area Networks (LANs) and other types of networks. WAN topology refers to the physical or logical layout of the network.

There are several WAN topologies, including hub-and-spoke, full mesh, point-to-point, and single-homed. Each has its own advantages and disadvantages and is suitable for different network requirements.

A hub-and-spoke topology is a centralized network where all traffic flows through a central hub or node. This topology is commonly used in networks where one site acts as the central location, and the other sites connect to it. However, this topology is not suitable for networks where each site needs to connect directly to all other sites.

A point-to-point topology connects two sites directly with a dedicated link. This topology is commonly used in networks where there are only two sites to connect, and a high-speed dedicated connection is required. However, it can be costly to implement this topology for multiple sites.

A single-homed topology connects a site to a single provider network, which may not provide redundancy or backup options. This topology is commonly used in small networks where redundancy is not a significant concern.

A full mesh topology connects each site directly to all other sites on the network. This topology provides the highest level of redundancy and allows for multiple paths between sites, making it the most fault-tolerant topology. However, it can be costly to implement, as it requires a large number of dedicated links.

In summary, a full mesh topology provides a direct connection from each site to all other sites on the network, making it the best option for networks that require high redundancy and fault tolerance.
