At your workstation you have received a complaint that the internet is having issue. You accelerate an
issue and ask your subordinate to investigate. He checks the router and finds that it is off by some
minutes. He configures NTP on the router just to get time from a Stratum 2 on the Internet. He has
found that there is a huge time difference and synchronizing for NTP is taking time on the local router.
Thus, to speedup synchronization process, he uses NTP command on the router to synch the time with
the time on the time provider.
Name the NTP term which best describes this process?
One of your daily task is to confirm the time on the router. One day, you find that it is off by about 10

router. Time has been successfully synching after a few minutes.
