CISSP – Information Systems Security Architecture Professional (ISSAP) — Question 74

You want to implement a network topology that provides the best balance for regional topologies in terms of the number of virtual circuits, redundancy, and performance while establishing a WAN network. Which of the following network topologies will you use to accomplish the task?

Answer options

• A. Bus topology
• B. Fully meshed topology
• C. Star topology
• D. Partially meshed topology

Correct answer: D

Explanation

The partially meshed topology is the correct choice as it offers a balance of connectivity and redundancy without the complexity and high costs associated with a fully meshed topology. The bus and star topologies do not provide adequate redundancy and performance for WAN requirements, making them less suitable for this scenario.
