What role does the administrative distance play in static routing?

• A. It determines the reliability of a static route
• B. It allows static routes to override dynamic routes
• C. It sets priorities for routing paths
• D. It influences the performance of routing protocols

Answer: (B)

In the context of static routing, the administrative distance serves as a measure that is used to rank the trustworthiness of different routes leading to the same destination. Specifically, in the case of static routes, they typically have a lower administrative distance (usually a value of 1) compared to dynamic routes, which usually have higher values (for example, OSPF has a default value of 110). When a router has to choose between static and dynamic routes to the same destination, the route with the lower administrative distance is preferred. This means that static routes will take precedence over dynamic routing protocols, allowing network engineers to create predetermined paths that can effectively override dynamically learned routes. This ability is crucial in scenarios where predictable routing behavior is needed, or in configurations that require a specific route to be favored. Thus, the role of administrative distance in static routing is fundamental, as it determines the precedence of static routes over dynamic ones.
