Which command would correctly remove a static route from a router's configuration?

• A. no ip route destination-address mask next-hop-address
• B. delete ip route destination-address mask next-hop-address
• C. remove ip route destination-address mask next-hop-address
• D. clear ip route destination-address mask next-hop-address

Answer: (A)

The command that effectively removes a static route from a router's configuration is structured as "no ip route destination-address mask next-hop-address." This syntax is a common practice in Cisco IOS, where the "no" prefix is used to negate or remove a configuration command. When you use "no ip route," you are instructing the router to delete the specific static route defined by its destination address, mask, and next-hop address. This command directly modifies the router's running configuration to exclude the specified static route, which is essential for managing routing tables and ensuring optimal routing behavior. The use of “no” as a negation is standardized in Cisco command-line interface (CLI) configurations, making it an intuitive way to remove existing settings. Understanding this command is crucial for network administrators, as it allows for dynamic management of routes as network topologies change.
