What is the effect of adjusting the 'distance' parameter on a static route?

• A. It sets the administrative distance; lower distance takes precedence over other routes to the same destination
• B. It changes the interface MTU
• C. It modifies DNS resolution
• D. It updates the router's hostname

Answer: (A)

Administrative distance is about which route the router trusts more when it has multiple ways to reach the same destination. The distance parameter on a static route sets that trust level. A lower distance means the static route is preferred over routes learned from other sources, so it wins in the routing table. If you increase the distance, the static route becomes less preferred and may be replaced by a better (lower-AD) route from a dynamic protocol or another source. This setting does not affect interface MTU, DNS resolution, or the router’s hostname. For example, a static route with distance 1 will beat a dynamic route with distance 110; raise the static route’s distance above 110, and the dynamic route would be chosen instead.
