Dell EMC Associate – Midrange Storage — Question 8

Which port and protocol is used by NTP to communicate?

Answer options

• A. TCP port 123 for both the source and destination
• B. TCP port 123 for the source and TCP port 80 for the destination
• C. UDP port 123 for both the source and destination
• D. UDP port 123 for the source and TCP port 80 for the destination

Correct answer: C

Explanation

The correct answer is C, as NTP (Network Time Protocol) uses UDP port 123 for both source and destination to synchronize time between devices. Options A and B incorrectly state that TCP is used, which is not the case for NTP. Option D also incorrectly mixes UDP for the source with TCP for the destination, which is not how NTP operates.
