The correct answer is: 4

Using a minimum of three NTP servers is recommended to ensure redundancy when configuring NTP for a Nutanix cluster. This approach allows the system to maintain accurate time synchronization, which is crucial for the proper functioning of various components within the cluster. When three NTP sources are used, it ensures that even if one server becomes unavailable or provides inaccurate time, the other two can still maintain a consensus on the correct time. This redundancy helps in avoiding scenarios where a single point of failure may disrupt time synchronization across the system. Having an even number of NTP sources, such as two or four, can lead to situations where there is no clear majority when one server fails, potentially resulting in time discrepancies. Therefore, three NTP servers strike a good balance between redundancy and reliability, allowing the cluster to continue functioning smoothly even in case of partial failures of the NTP servers. The consideration of adding an even higher number of NTP sources, such as five, might seem appealing for additional redundancy, but it is generally unnecessary given that most environments will effectively manage time synchronization with three. Adding too many servers can also introduce complexity into the configuration and increase the chances of misconfigurations. Hence, three is the optimal choice for redundancy in a Nutanix
