200-301 Question 38
Single answerA company is designing a new network to support its growing operations. The network must ensure high availability, scalability, and fault tolerance. Which network topology architecture would best meet these requirements?
- A
Star topology
- B
Bus topology
- C
Mesh topology
- D
Ring topology
Show answer and explanation
Correct answer: C
Explanation
Mesh topology is the best choice for a network that requires high availability, scalability, and fault tolerance. It ensures multiple redundant paths between devices, minimizing the impact of failures and supporting growth as more devices are added to the network.
- A. Incorrect.
Star topology provides centralized connectivity and is easy to manage, but it does not inherently offer fault tolerance or scalability as the central hub is a single point of failure.
- B. Incorrect.
Bus topology is cost-effective and simple, but it is not scalable and a single failure in the backbone can disrupt the entire network.
- C. Correct.
Mesh topology offers high availability, scalability, and fault tolerance by providing multiple paths between devices, ensuring that a single failure does not disrupt the network.
- D. Incorrect.
Ring topology uses a circular data flow, which can provide some redundancy in certain cases, but it is not as scalable or fault-tolerant as a mesh topology.
