An administrator is responsible forresource planningand needs to plan forresiliencyof a10-node RF3 cluster.

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 spacebased on cluster size and RF settings.

It ensures thatenough storage remains available in case of a node failure.

Option A (Set Reserve Storage Capacity to 20%) is incorrect:

The required storage reservationdepends 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 toRAM, notstorage resiliency.
