✑ vRAM: 64 GB
✑ vDisk: 1.5 TB
Each of the four nodes of the Nutanix cluster has the following:
✑ 24 vCPU. 20% overall usage
✑ 192 GB RAM, 60% overall usage
✑ 2 x l920 GB SSD
✑ 4 x 2 TB HDD
At cluster level, there is a single RF2 container that is 30% utilized and has an extent store capacity of 13.5 TB.
Which component requires administrator attention?

  • A. Physical RAM, because it is not enough to power on all of the new VMs.

Option A. As stated in the question, 60% of the total RAM in the Nutanix cluster is in use (based on '192 GB RAM, 60% overall usage'), which amounts to 768 GB (192 GB per node * 4 nodes). This means that only 40% of the remaining RAM in the cluster, equivalent to 307.2 GB (768 GB * 40%), is available for the creation of the five VMs. Since the total amount of vRAM needed for the five VMs is 320 GB (64 GB per VM * 5 VMs), it exceeds the available RAM (320 GB > 307.2 GB), making Option A the correct answer.
