A network team is comparing physical WAN topologies for connecting remote sites to a headquarters building. Which topology provides high availability and connects some, but not all, remote sites?meshhub and spokepoint-to-pointpartial mesh

The topology that provides high availability and connects some, but not all, remote sites is the partial mesh topology.

Here's a step-by-step explanation:

1. In a partial mesh topology, not all nodes are directly connected to every other node, unlike a full mesh topology.

2. Some nodes are connected to all others, but some are only connected to those with which they exchange the most data. This makes it a cost-effective choice as it requires fewer lines than a full mesh topology.

3. This topology strikes a balance between the redundancy of a full mesh topology and the minimal connections of a star or hub-and-spoke topology.

4. Therefore, it provides high availability because there are multiple paths for data to travel, reducing the likelihood of a single point of failure.

5. At the same time, it doesn't require a direct connection between every pair of remote sites, making it more scalable and less expensive to implement than a full mesh topology.
