Which of the following best describes the network arrangement used by Fibre…

Concept

A token-passing network grants transmission permission through a control token that circulates among stations. Ring arrangements provide a closed path for this circulation; a dual counter-rotating ring adds resilience when one path is disrupted.

Application

FDDI carries data over optical fibre at 100 Mbps and uses token passing on two counter-rotating rings. The primary ring normally carries traffic, while the secondary ring provides an alternate path during a fault.

Contrast

• Token Bus uses a shared physical bus with a logical token-passing order.

• Star topology connects all outer stations through one central hub or switch.

• Mesh topology uses many direct point-to-point links between stations.

• Token ring circulates transmission permission around a closed ring, matching FDDI's token-passing dual-ring design.

Result

Therefore, among the given choices, FDDI is best described as Token ring.
