Centrally Located Server Farm and Satellite Branches

B

The most appropriate WAN topology for a centrally located server farm with several satellite branches would be the hub and spoke topology. The hub and spoke topology is also known as the star topology, and it is commonly used in WANs.

In a hub and spoke topology, all traffic between the satellite branches and the central location (the hub) passes through the hub. The hub acts as a central point of control for all traffic and provides a single point of entry for remote access. This topology is useful in scenarios where there are many remote locations that need to connect to a central location, as it allows for centralized management and control.

In the case of a server farm with several satellite branches, the hub and spoke topology would allow the central location to act as the main data center, with the satellite branches connecting to the hub to access resources such as files, databases, and applications. This topology would also provide centralized management of the network, making it easier to monitor and maintain.

Alternatively, a full mesh topology could also be used. In a full mesh topology, each satellite branch is connected to every other satellite branch, creating a fully connected network. This topology provides high redundancy and fault tolerance, as any node can communicate with any other node in the network. However, it is typically more expensive and difficult to manage than a hub and spoke topology, especially as the number of nodes increases.

A point-to-point topology, on the other hand, is designed for connecting two nodes directly, which would not be suitable for a scenario with multiple satellite branches. The star topology, which is similar to the hub and spoke topology, would also be a good option, but the hub and spoke topology would be more appropriate for a scenario where there is a central location with several remote branches.
