A customer has seven sites, three of which process a large amount of traffic among them. The customer plans to grow the number of sites in the future. Which is the most appropriate design topology?
The correct answer is C. partial mesh. Partial mesh is the best fit here. The three high-traffic sites benefit from direct links between each other (avoiding bottlenecks), while the remaining four sites connect to one or more of those core sites without requiring direct links to every other site. Full mesh (A) would…

Explanation
Partial mesh is the best fit here. The three high-traffic sites benefit from direct links between each other (avoiding bottlenecks), while the remaining four sites connect to one or more of those core sites without requiring direct links to every other site. Full mesh (A) would require n*(n-1)/2 links - expensive and harder to scale as the customer adds sites. Hub and spoke (D) would force all traffic through a single hub, creating a bottleneck for the three high-traffic sites. Peer-to-peer (B) is not a standard WAN topology term in this context. Partial mesh balances performance where it matters with cost-efficiency and room for growth.
