100-150 Question 32
Single answerA small business is setting up a new network for its office. The network must ensure that if one device or connection fails, it does not affect the rest of the network's operations. Which of the following physical or logical topologies should they implement to meet this requirement?
- A
Star topology
- B
Bus topology
- C
Ring topology
- D
Mesh topology
Show answer and explanation
Correct answer: A
Explanation
The star topology is ideal for a small business due to its simplicity and ability to isolate failures. If one device or its connection to the central hub fails, it does not affect the operation of other devices on the network. This makes it a reliable choice compared to bus or ring topologies, which are more vulnerable to failures.
- A. Correct.
Star topology ensures that each device is connected to a central hub or switch. If one connection or device fails, it does not affect the rest of the network, making it resilient to single-point failures.
- B. Incorrect.
Bus topology has all devices connected to a single central cable. If there is a failure in the main cable, the entire network is disrupted, making it less resilient.
- C. Incorrect.
Ring topology connects devices in a circular manner, where data flows in a specific direction. If any single device or connection fails, the entire network can be impacted unless additional redundancy is implemented.
- D. Incorrect.
Mesh topology provides redundancy by connecting every device to multiple other devices. While it is resilient, it is overkill for a small business and can be complex and expensive to implement.
