The route command can

The route command can

• A. Ping a host to test connectivity
• B. Show the current DNS cache
• C. Add, modify, or delete routes in the IP routing table of Windows and UNIX hosts
• D. List active processes

Answer: (C)

Controlling how packets are forwarded depends on the routing table, and the route command is the tool that directly manages that table. It lets you add new routes to direct traffic for particular networks to specific gateways, modify existing routes as network conditions change, or delete routes that are no longer valid. This is essential for shaping reachability, selecting the right interface, and setting route metrics to influence path selection on both Windows and UNIX-like systems. For example, you can view the current routes to verify entries and then apply persistent changes as needed. By contrast, ping checks whether a host can be reached, DNS cache display reveals name resolution data, and listing processes shows active programs—none of which alter how routing decisions are made.
