What is the typical Administrative Distance value associated with static routes?

• A. 0
• B. 110
• C. 50
• D. 1

Answer: (D)

Administrative Distance is the measure of how trustworthy a routing source is, with lower values meaning more trust. Static routes are configured manually by the administrator, so they’re treated as highly trustworthy. On most routers, the distance assigned to a static route is very low—lower than the distances used by dynamic routing protocols such as OSPF or RIP. Because of this, if both a static route and a dynamic route exist to the same destination, the router will prefer and install the static route in its routing table. The only case you might see a static route not used is when you’ve raised its distance (making it less preferred) so it acts as a backup, but in the standard situation the static route wins due to its low distance.
