Which command configures a name on the router?

• A. Router(config)# hostname CL1
• B. Router(config)# name CL1
• C. Router(config)# interface CL1
• D. Router(config)# enable CL1

Answer: (A)

Setting the device’s identity is done by configuring its hostname in global configuration mode. In Cisco IOS, the hostname you assign becomes the name shown in the prompt and how the device is identified on the network. By entering hostname CL1, you explicitly set the router’s name to CL1, which updates the prompt to CL1#. This makes it easy to distinguish this router from others in a network with multiple devices and is essential for management and administration. The other options don’t rename the device. Configuring an interface changes per-interface settings, not the router’s overall name. A standalone name command isn’t a valid way to set the hostname in this context. The enable command relates to privileged EXEC mode or its passwords, not to naming the router.
