What command does Edwin use to retrieve the routing table and check for persistent routes?

The command that Edwin should use to retrieve the routing table and check for persistent routes is indeed "route." This command is specifically designed to display and manipulate the IP routing table on a computer.

When executed, the "route" command provides details about all the current routes along with their associated metrics, including persistent routes that remain in the routing table even after a reboot. It allows network administrators and users to view these routes and, if needed, make modifications to them, such as adding new routes or deleting existing ones.

The other commands listed do have specific functions in networking but do not serve the purpose of retrieving and managing the routing table as the "route" command does. For instance, "ipconfig" is primarily used to display and manage IP configuration settings for network interfaces, while "netstat" provides information on network connections and statistics, and "tracert" traces the path that packets take to a specific network host, showing the route taken but not the actual routing table itself. Thus, the best choice for retrieving the routing table and checking for persistent routes is "route."
