Why is it important to configure a hostname on a device?
- a Cisco router or switch only begins to operate when its hostname is set
- a hostname must be configured before any other parameters
- to identify the device during remote access (SSH or telnet)
- to allow local access to the device through the console port
Explanation:It is important to configure a hostname because various authentication processes use the device hostname. Hostnames are helpful for documentation, and they identify the device during remote access.
