Which two statements are true regarding the use of NTP clock synchronization? (Choose two.)

Junos OS implements the NTP protocol, which includes support for operating in client mode to receive time, server mode to provide time, and symmetric mode for peer-to-peer synchronization, offering flexibility in time synchronization deployments.

Consistent and synchronized timestamps from log messages across multiple network devices are crucial for correlating events, identifying sequences of actions, and accurately diagnosing network issues during troubleshooting.

NTP supports authentication methods (like MD5 or SHA-1) to ensure the integrity and authenticity of time synchronization packets, preventing malicious time manipulation.

While a Junos OS device can act as a primary time reference, it is not a requirement; any reliable NTP server (e.g., dedicated hardware clock, public NTP server) can serve as the primary reference.
