An administrator needs to configure a backup static route on a router that becomes active when the primary route is unavailable. Which configuration should the administrator implement to accomplish this?
Configure a static route with a lower priority than the primary route.
Configure a static route with a different next-hop IP address.
Configure a static route with a higher administrative distance than the primary route.
Configure a static route with a higher metric value than the primary route.
To set up a backup static route, the administrator should configure a static route with a higher administrative distance than the primary route. This type of route is known as a floating static route. The administrative distance determines the preference of routes; lower values are preferred over higher ones. By assigning a higher administrative distance to the backup route, it remains inactive until the primary route fails.
Configuring a static route with a lower priority than the primary route is incorrect because static routes do not use a priority value for route selection. Setting a higher metric value applies to dynamic routing protocols, not static routes. Using a different next-hop IP address alone does not ensure the route acts as a backup.
