CompTIA Network+ (N10-009) — Question 141

A network administrator wants to configure a backup route in case the primary route fails. A dynamic routing protocol is not installed on the router. Which of the following routing features should the administrator choose to accomplish this task?

Answer options

• A. Neighbor adjacency
• B. Link state flooding
• C. Administrative distance
• D. Hop count

Correct answer: C

Explanation

The correct answer is C, Administrative distance, because it allows the router to prioritize routes based on their reliability. The other options, such as Neighbor adjacency and Link state flooding, are related to how routers communicate and share routing information, while Hop count is a metric used in distance-vector routing protocols, but does not directly address backup routing.
