Question
Which two statements are true regarding the use of NTP clock synchronization? (Choose two.)
Options
- AThe Junos OS supports client, server, and symmetric modes of NTP operation.
- BSynchronized time on all network devices makes log messages more useful for troubleshooting.
- CAuthentication methods are not supported.
- DThe Junos OS must be used as the primary time reference.
Explanation
NTP synchronization in Junos OS supports various operational modes and enhances network troubleshooting by ensuring consistent timestamps across devices.
Common mistakes.
- C. NTP supports authentication methods (like MD5 or SHA-1) to ensure the integrity and authenticity of time synchronization packets, preventing malicious time manipulation.
- D. 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.
