An administrator is setting up a Nutanix cluster for a mission critical workload. All of the VMs in the cluster must have capacity to continue to run even if there is a hardware failure.
What should the administrator enable to achieve this requirement?
To ensure that all VMs in a Nutanix cluster have the capacity to continue running even if there is a hardware failure, the administrator should enable HA Reservation in Prism Element. High Availability (HA) Reservation guarantees that reserved resources are available to restart VMs on another node in case of a hardware failure, thus meeting the specified requirement for mission-critical workloads.
AHV can be configured to reserve capacity throughout the cluster. This guarantees that all VMs can be restarted in the event of a node failure.
Because it's about ensuring capacity, A and D aren't relevant. C doesn't change the capacity available in the event of a failure, just allows for a second failure (which the question isn't asking for). This one's B.
I believe B is correct. The question is about resource capacity, which usually refers to CPU and memory. There is no mention of storage availability in the question.
Setting the redundancy factor to 3 means that there will be three copies of the data distributed across the nodes in the cluster. This provides high availability and ensures that even if one node fails, the other copies of the data on different nodes can be used to continue running the VMs without interruption. This is a key feature in maintaining data availability and workload continuity in the case of hardware failures.
The default of RF2 comes with a FT1, which is all the question seems to be asking for with "a hardware failure" rather than "2 hardware failures."
