Which two benefits of implementing a full-mesh WAN topology are true? (Choose two.)
The correct answer is B. redundancy D. reliability. A full-mesh WAN topology provides excellent redundancy and reliability because every node has a direct connection to every other node, creating multiple paths for data.

Why each option
A full-mesh WAN topology provides excellent redundancy and reliability because every node has a direct connection to every other node, creating multiple paths for data.
While direct paths can reduce the number of hops and thus potentially latency, 'increased latency' is not a general benefit of a full-mesh topology; it is often associated with the complexity of managing many links.
In a full-mesh topology, every node is directly connected to every other node, providing inherent redundancy by offering multiple alternative paths for data transmission if a link fails.
Reduced jitter can be a result of direct paths and less congestion, but it is not a primary or defining benefit of a full-mesh topology compared to its inherent redundancy and reliability.
Due to the multiple direct connections and redundant paths, a full-mesh topology offers very high reliability, as the failure of a single link or even multiple links will not isolate any node.
A full-mesh topology suffers from poor scalability as the number of required connections grows quadratically with the number of nodes (n*(n-1)/2), making it impractical for large networks.
