A network engineer needs to set up a topology that will not fail if there is an outage on a single piece of the topology. However, the computers need to wait to talk on the network to avoid congestions. Which of the following topologies would the engineer implement?
A. Star
B. Bus
C. Ring
D. Mesh
Answer:C

Explanation: Token Ring networks are quite rare today. Token Ring networks use the ring topology. Despite being called a Ring topology, the ring is logical and the physical network structure often forms a ‘star’ topology with all computers on the network connecting to a central multistation access unit (MAU). The MAU implements the logical ring by transmitting signals to each node in turn and waiting for the node to send them back before it transmits to the next node. Therefore, although the cables are physically connected in a star, the data path takes the form of a ring. If any computer or network cable fails in a token ring network, the remainder of the network remains functional. The MAU has the intelligence to isolate the failed segment.
