CompTIA Network+ (N10-008) — Question 682
Which of the following is the most accurate NTP time source that is capable of being accessed across a network connection?
Answer options
- A. Stratum 0 device
- B. Stratum 1 device
- C. Stratum 7 device
- D. Stratum 16 device
Correct answer: B
Explanation
The Stratum 1 device is directly connected to an accurate time source, making it the most reliable and precise for network time synchronization. Stratum 0 devices are not network-accessible, while Stratum 7 and Stratum 16 devices represent less accurate sources, with Stratum 16 being reserved for servers that are not synchronized.
