CompTIA Network+ (N10-008) — Question 511

An organization has a factory automation solution that requires accurate timing between devices. Which of the following should the network administrator implement?

Answer options

• A. PTP
• B. NTP
• C. NTS
• D. DoT

Correct answer: B

Explanation

The correct answer is B, NTP (Network Time Protocol), which is designed for synchronizing clocks over a network and is sufficient for most applications requiring time accuracy. PTP (Precision Time Protocol) is more precise than NTP but may not be necessary for all factory automation solutions. NTS (Network Time Security) is a security extension for NTP, and DoT (DNS over TLS) is unrelated to time synchronization.
