100-150 Question 34
Single answerYou are troubleshooting a network issue for a small office. The network is set up in such a way that all devices are connected to a central switch, and the failure of any single device does not impact the connectivity of other devices. Which physical network topology is being used in this scenario?
- A
Star topology
- B
Bus topology
- C
Ring topology
- D
Mesh topology
Show answer and explanation
Correct answer: A
Explanation
The described scenario matches the characteristics of a star topology, where all devices connect to a central switch, and the failure of one device does not impact others. This is a common topology for small offices due to its simplicity and fault isolation.
- A. Correct.
In a star topology, all devices are connected to a central device, such as a switch or hub. A single device failure does not affect the rest of the network, making this the correct answer.
- B. Incorrect.
A bus topology uses a single backbone cable to connect all devices. If the backbone fails, the entire network is disrupted, which does not match the scenario.
- C. Incorrect.
In a ring topology, devices are connected in a circular manner, and the failure of a single device can disrupt the entire network unless special redundancy measures are in place.
- D. Incorrect.
A mesh topology involves multiple interconnections between devices, providing high redundancy. However, this is not described in the scenario.
