NCS-Core Exam Dumps : Nutanix Certified Services Core Infrastructure Professional (NCS-Core 6.8)

When managing multiple Nutanix AHV clusters across various locations with a centralized management through Prism Central, it is essential to secure each cluster individually. Integrating Microsoft Active Directory authentication directly on all Prism Element clusters allows each site to independently authenticate users while still being centrally managed. This method aligns with security policies that require network devices to authenticate via AD groups, ensuring that local administrative actions at each site are also secured under the same policy.

To increase the Redundancy Factor (RF) from 2 to 3, at least five nodes are required for the cluster to function correctly with RF3, as each data block needs to be replicated to three different nodes. However, the optimal solution that offers both the necessary node count and sufficient storage overhead is:

• Six Compute Nodes with 25% available disk space: This configuration ensures that there are enough nodes to support RF3 while maintaining adequate storage capacity for redundancy without overutilization.
