200-301 Question 37
Single answerA network engineer is designing a network for a small office. The office requires a topology that allows easy troubleshooting, scalability, and minimal downtime in case of a single device failure. Which network topology architecture should the engineer choose?
- A
Bus topology
- B
Star topology
- C
Ring topology
- D
Full mesh topology
Show answer and explanation
Correct answer: B
Explanation
Star topology is the most appropriate choice for the small office as it provides easy troubleshooting, scalability, and ensures that a single device failure does not impact the entire network. While other topologies have their own benefits, they either lack scalability, are harder to troubleshoot, or are too complex and costly for the given scenario.
- A. Incorrect.
Bus topology uses a single cable to connect all devices, which makes it difficult to troubleshoot and prone to downtime if the main cable fails.
- B. Correct.
Star topology connects all devices to a central hub or switch. It is easy to troubleshoot, scalable, and a failure of one device does not affect the rest of the network.
- C. Incorrect.
Ring topology connects devices in a circular manner, and a single device failure can disrupt the entire network unless additional redundancy measures are implemented.
- D. Incorrect.
Full mesh topology offers high redundancy but is complex and expensive to scale, making it less suitable for a small office environment.
