CCNA: Cisco Certified Network Associate — Question 24

When a floating static route is configured, which action ensures that the backup route is used when the primary route fails?

Answer options

• A. The administrative distance must be higher on the primary route so that the backup route becomes secondary.
• B. The default-information originate command must be configured for the route to be installed into the routing table.
• C. The floating static route must have a lower administrative distance than the primary route so it is used as a backup.
• D. The floating static route must have a higher administrative distance than the primary route so it is used as a backup

Correct answer: D

Explanation

The correct answer is D because for a floating static route to act as a backup, it should have a higher administrative distance than the primary route, ensuring it only takes effect when the primary fails. Option A is incorrect since the primary route must have a lower administrative distance. Option B is irrelevant to the concept of floating static routes, and option C contradicts the definition of a floating static route.
