200-301 Question 40
Single answerA company is expanding its network to connect multiple branch offices to the main corporate office. The network design needs to ensure high availability, scalability, and efficient use of bandwidth. Which network topology architecture would be most suitable for this requirement?
- A
Star topology
- B
Full mesh topology
- C
Partial mesh topology
- D
Bus topology
Show answer and explanation
Correct answer: C
Explanation
Partial mesh topology is the most suitable choice for connecting multiple branch offices to a main corporate office. It provides a balance between availability, scalability, and efficient use of bandwidth by strategically connecting key nodes and avoiding the excessive complexity of a full mesh topology. This design meets the company's requirements for a reliable and scalable network.
- A. Incorrect.
Star topology is not suitable for connecting multiple branches because it relies on a single central hub, making it less scalable and resilient in the case of hub failure.
- B. Incorrect.
Full mesh topology ensures high availability but is not bandwidth efficient or scalable for larger networks because it requires every node to connect to every other node, which increases complexity and cost.
- C. Correct.
Partial mesh topology balances high availability and efficient use of bandwidth by connecting key nodes directly while allowing other nodes to connect via intermediary nodes. This makes it scalable and cost-effective for connecting multiple branch offices to a central location.
- D. Incorrect.
Bus topology is outdated and not suitable for large, modern networks due to its lack of scalability and resilience. A single point of failure in the bus can disrupt the entire network.
