100-150 Question 33
Single answerA small organization is setting up a network for their office and wants to ensure that if one connection fails, the rest of the network remains operational. Which of the following network topologies would best meet this requirement?
- A
Bus topology
- B
Star topology
- C
Ring topology
- D
Mesh topology
Show answer and explanation
Correct answer: D
Explanation
Mesh topology is the most suitable choice for fault tolerance in a network. Its redundant connections ensure that even if one link fails, the rest of the network remains operational, meeting the organization's requirement for high reliability.
- A. Incorrect.
Bus topology connects all devices using a single communication line. If the main line fails, the entire network is disrupted, so it does not meet the requirement.
- B. Incorrect.
Star topology connects all devices to a central hub. If the hub fails, all connections are lost, so it does not provide the desired fault tolerance.
- C. Incorrect.
Ring topology connects devices in a closed loop. If a single connection fails, communication is interrupted unless additional mechanisms are implemented, so it does not fully meet the requirement.
- D. Correct.
Mesh topology connects devices with multiple redundant paths. This ensures that even if one connection fails, alternative paths are available, making it the best option for fault tolerance.
