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.
