What is the importance of having multiple NTP sources in a Nutanix cluster?

  1. To avoid time synchronization issues

  2. To increase backup frequency

  3. To enhance cluster performance

  4. To manage user permissions

The correct answer is: To avoid time synchronization issues

Establishing multiple NTP (Network Time Protocol) sources within a Nutanix cluster is crucial for maintaining accurate and consistent time synchronization across all nodes in the cluster. Accurate timekeeping is fundamental for various operations, including logging, scheduling tasks, and ensuring that timestamps on data are aligned. When nodes operate under the same time standard, it minimizes discrepancies that could lead to issues such as data corruption, problems with scheduled tasks, and complications in data replication processes. Having multiple NTP sources acts as a safeguard against the failure of any single time server. This redundancy ensures that if one NTP server becomes unavailable or experiences issues, the cluster can continue to synchronize its time with other available servers, maintaining operational integrity. This practice ultimately helps to prevent time synchronization-related issues that could disrupt cluster performance or cause service outages, making it essential for reliable cluster operations.
