300-420 Question 132
Single answerAn enterprise network design for a global organization requires a topology that ensures high availability, low latency between data centers, and scalability to handle future growth. Which of the following topologies would be most optimal for this scenario?
- A
Full mesh topology
- B
Star topology
- C
Hub-and-spoke topology
- D
Ring topology
Show answer and explanation
Correct answer: A
Explanation
For a global organization requiring high availability, low latency, and scalability, a full mesh topology is the most optimal. This topology ensures direct connections between all nodes, enabling fast communication and fault tolerance. While it is more resource-intensive, it meets the performance and reliability requirements of the scenario better than the other topologies.
- A. Correct.
Full mesh topology is ideal for scenarios requiring high availability and low latency as every node is directly connected to every other node, providing redundancy and multiple paths for communication. It is also scalable with proper planning.
- B. Incorrect.
Star topology centralizes communication through a single hub, which introduces a single point of failure and potential bottlenecks, making it less suitable for high availability and low latency requirements.
- C. Incorrect.
Hub-and-spoke topology is cost-effective but depends heavily on the central hub, making it less optimal for scenarios requiring high availability and low latency between nodes.
- D. Incorrect.
Ring topology connects nodes in a circular fashion, which can lead to higher latency and limited scalability compared to other topologies, making it less suitable for the given requirements.
