220-801 · Question #204

Which of the following network topologies is MOST likely to affect other devices on the network if there is a problem with one of the devices?

The correct answer is C. Ring. In a ring topology, data travels sequentially through each node in a loop, so a single device failure can break the ring and disrupt all communication.

Why each option

In a ring topology, data travels sequentially through each node in a loop, so a single device failure can break the ring and disrupt all communication.

AMesh

Mesh topology provides multiple redundant paths between devices, so a single device failure does not disrupt the rest of the network.

BBus

In a bus topology, devices are passive taps on a shared cable, so a single device failure typically does not prevent other devices from communicating.

CRingCorrect

Ring topology passes data from node to node in a circular path, meaning every device in the ring is part of the single data path. If any one device fails or is removed, the entire ring is broken and no other devices can communicate until the fault is resolved.

DStar

Star topology uses a central switch or hub, so a single end-device failure only isolates that one device and does not affect others.
