Certified Information Systems Auditor (CISA) — Question 1322
Which of the following network topologies will provide the GREATEST fault tolerance?
Answer options
- A. Star configuration
- B. Bus configuration
- C. Ring configuration
- D. Mesh configuration
Correct answer: D
Explanation
The Mesh configuration is the correct answer because it connects each device to multiple other devices, ensuring that if one link fails, there are alternative paths for data transmission. In contrast, the Star configuration relies on a central hub, the Bus configuration has a single point of failure, and the Ring configuration can be disrupted if one connection goes down, making them less fault-tolerant.
