Which command must be entered when a device is configured as an NTP server?

Answer options

• A. ntp peer
• B. ntp master
• C. ntp authenticate
• D. ntp server

Correct answer: B

Explanation

The correct command for configuring a device as an NTP server is 'ntp master', which designates the device as the authoritative time source. The other options, such as 'ntp peer', are used for different configurations, while 'ntp authenticate' and 'ntp server' do not set the device as a master NTP server.
