Nutanix NCP-MCI Exam - Topic 2 Question 41 Discussion
Topic #: 2
An administrator is responsible for resource planning and needs to plan for resiliency of a 10-node RF3 cluster. The cluster has 100TB of storage.
How should the administrator plan for capacity in the event of future failures?
RF3 (Replication Factor 3) clusters require sufficient reserved capacity to tolerate failures without data loss.
Option C (Set Reserve Capacity for Failure to Auto Detect) is correct:
Auto Detect dynamically calculates the necessary reserved space based on cluster size and RF settings.
It ensures that enough storage remains available in case of a node failure.
Option A (Set Reserve Storage Capacity to 20%) is incorrect:
The required storage reservation depends on the number of nodes and RF level, not a fixed percentage.
Option B (Set Reserve Capacity for Failure to None) is incorrect:
Without reserved capacity, a node failure could lead to data unavailability.
Option D (Set Reserve Memory Capacity to 20%) is incorrect:
This setting applies to RAM, not storage resiliency.
