CompTIA Network+ (N10-008) — Question 153

A network administrator needs to configure a server to use the most accurate NTP reference available. Which of the following NTP devices should the administrator select?

Answer options

• A. Stratum 1
• B. Stratum 2
• C. Stratum 3
• D. Stratum 4

Correct answer: A

Explanation

The correct answer is Stratum 1 because it represents the highest level of accuracy available for NTP servers, being directly connected to an authoritative time source. Stratum 2, Stratum 3, and Stratum 4 provide less accuracy as they are further down the hierarchy and depend on Stratum 1 servers for their time synchronization.
