What should an administrator do to remove a static route from the routing table if the destination network no longer exists?

• A. Remove the route using the no ip route command
• B. Disable the router interface
• C. Reboot the router
• D. Change the route metric

Answer: (A)

To remove a static route from the routing table when the destination network is no longer available, the appropriate action is to use the command to remove that specific route, which is achieved by executing the "no ip route" command. This command effectively deletes the static route entry from the router's configuration and its routing table, ensuring that the router does not attempt to send packets to a non-existent network. When the static route is removed, the router will reevaluate its routing decisions based on the remaining available routes. This ensures that traffic is directed correctly based on current operational networks, ultimately enhancing network efficiency and reliability. Options like disabling the router interface or rebooting the router do not directly address the need to remove the outdated route and could cause additional downtime or disruption in network services. Changing the route metric may affect the path selection for existing routes but does not remove the route itself and would not be effective for a network that no longer exists. Therefore, using the no ip route command is the precise and necessary action in this scenario.
