200-301 Question #852: Real Exam Question with Answer & Explanation

Question

Which two benefits of implementing a full-mesh WAN topology are true? (Choose two.)

Options

• Aincreased latency
• Bredundancy
• Creduced jitter
• Dreliability
• Eimproved scalability

Explanation

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.

Common mistakes.

• A. 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.
• C. 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.
• E. 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.
