An administrator needs to create and start five new VMs for a Data Analytics Project (OLAP). The VM Profile is as follows:
✑ vCPU:4
✑ 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?
The component that requires attention is the Physical RAM. Each new VM requires 64 GB of vRAM, and with five VMs being created, a total of 320 GB of vRAM is needed. The cluster has a total of 768 GB of RAM (192 GB per node across four nodes) of which 60% is already utilized, leaving 307.2 GB available. Since 320 GB is required and only 307.2 GB is available, there isn't enough RAM to power on all 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.
