CompTIA DataX (CNX-001) — Question 19

A network architect is creating a network topology for a global SD-WAN deployment. The business has offices in Asia, Europe, and the United States and makes use of data centers in the United States and Europe. Most traffic between sites must have the lowest latency possible. Which of the following topologies best meets this requirement?

Answer options

• A. Star
• B. Spine-and-leaf
• C. Mesh
• D. Hub-and-spoke

Correct answer: C

Explanation

The mesh topology is optimal for minimizing latency as it allows for multiple direct connections between sites, enabling the fastest route for data transmission. The star topology introduces a central hub that can create a bottleneck, while the hub-and-spoke model relies on a central point that can also increase latency. The spine-and-leaf topology, although efficient, is more suited for data center environments rather than a global WAN deployment.
