Which WAN topology has the highest degree of reliability? (CCNA 200-301)
Which WAN topology has the highest degree of reliability?
A. point-to-point
B. router-on-a-stick
C. full mesh
D. hub-and-spoke
Solution
Correct answer: C. full mesh.
A full mesh topology is a type of WAN topology where every site is connected to every other site. This means that if one connection goes down, there are multiple alternative paths for data to travel, making it the most reliable topology. In a full mesh topology, each site has a direct connection to every other site, providing redundancy and fault tolerance.
In contrast, point-to-point (A) and hub-and-spoke (D) topologies have single points of failure, and router-on-a-stick (B) is not a WAN topology, but rather a configuration for connecting multiple VLANs to a single router interface.
