What is the main benefit of redundancy in a network with multiple routes between endpoints?

• A. Increased latency due to routing complexity.
• B. Decreased security.
• C. Increased fault tolerance due to multiple routes.
• D. Decreased bandwidth.

Answer: (C)

Redundancy with multiple routes primarily improves fault tolerance and availability. When there are alternate paths between endpoints, if one link or device fails, traffic can automatically be redirected to another healthy path, keeping the connection up and minimizing downtime. Routing protocols detect failures and switch traffic quickly, so users experience fewer outages. While extra routes can introduce some overhead or be used to balance load, the core benefit is that the network remains reachable even in the face of component failures. The other options describe potential side effects, not the main purpose: redundancy is not aimed at increasing latency, decreasing bandwidth, or reducing security.
