Question
Refer to the exhibit. An administrator wants to make sure there are enough compute resources within the AHV-based Nutanix cluster during any maintenance operations or a node failure. What configuration should the administrator change to achieve this task?

Options
- AEnable Degraded Node Detection
- BEnable MA Reservation
- CReserve 33% CPU and 33% memory
- DSet virtual machine affinity rules

Explanation
In Nutanix AHV, enabling HA (High Availability) Reservation instructs the cluster to proactively set aside a portion of CPU and memory resources across all nodes so that if any single node fails or goes into maintenance mode, there is guaranteed spare capacity available to restart or migrate the VMs from that node. Without HA Reservation, the cluster runs at full utilization and a node failure could leave VMs unable to restart due to resource exhaustion. Option C describes manually setting specific percentages, but the correct Nutanix mechanism is to enable the HA Reservation feature, which automatically calculates and reserves the required resources. Degraded Node Detection (A) identifies failing hardware; VM affinity rules (D) control placement but do not reserve resources.
