Question

You check the time on router and find that it is behind by several minutes. To fix this issue, you decide to configure NTP on the router to get time from a Stratum 2 time provider on the Internet with a hostname of _______. Which command should you use?

1) ntp server
2) ntp client
3) ntp peer
4) ntp source

Answer 1

To configure NTP on a router, use the 'ntp server' command followed by the time provider's hostname to synchronize the router's time.

Step-by-step explanation:

To configure NTP (Network Time Protocol) on a router and synchronize the clock with a Stratum 2 time provider, you should use the command ntp server followed by the hostname of the time provider. For example, if the hostname is 'time.example.com', the full command would be ntp server time.example.com. This command will instruct the router to behave as an NTP client and receive reliable time updates from the specified time server. Using NTP ensures that the router maintains accurate time, which is vital for security, logging, and other time-sensitive functions.
