Episode 70: Network Time Protocol (NTP) — Keeping Clocks in Sync

This episode explains Network Time Protocol (NTP), which synchronizes clocks across devices to ensure accurate timestamps and coordinated operations. Accurate timekeeping is essential for authentication, logging, and troubleshooting, making NTP an important exam subject. The protocol operates in a hierarchical system of stratum levels, with stratum 0 as the most accurate reference clocks and higher strata providing distribution.

Practical considerations are discussed, such as how incorrect time settings can prevent secure logins, invalidate certificates, or disrupt logs. Troubleshooting tips include checking NTP server availability, verifying stratum levels, and diagnosing network delays affecting synchronization. By mastering NTP, you’ll be ready to interpret exam questions and maintain reliable system operations in professional environments.
