Nutanix strongly recommends configuringreliable internal NTP sources(e.g., enterprise-managed NTP servers or domain NTP servers) to ensure:
Time consistency across all nodes and CVMs
Accurate logging, monitoring, authentication (e.g., Kerberos), and cluster operations
Avoiding dependency onexternal/public NTPsources, which may berate-limited, unavailable, or blockedby firewalls
Clarifications:
A (Windows time sources):Generally discouraged unless they are configured to use a stratum 1/2 reliable upstream source.
C (Rate-limited sources):Not recommended; can result in dropped or inconsistent time updates.
D (External ISP NTP):Not preferred for production clusters due to reliability concerns.
