Report
Export

An administrator migrates a VM onto a new Nutanix cluster- After the migration, the administrator observes the following conditions:

* Cluster memory utilization: 64%

* Cluster CPU utilization: 19%

* Cluster storage utilization. 32%

* Average VM CPU utilization: 25%

* Average VM CPU ready%: 24%

* Average VM memory utilization: 60%

Which two changes should the administrator make to improve VM performance? (Choose two.)

A.
Reduce the number of vCPUs assigned to VMs.
Answers
A.
Reduce the number of vCPUs assigned to VMs.
B.
Add more memory to the VMs.
Answers
B.
Add more memory to the VMs.
C.
Reduce the number of VMs on the hosts.
Answers
C.
Reduce the number of VMs on the hosts.
D.
Replace high core count CPUs with high clock rate CPUs.
Answers
D.
Replace high core count CPUs with high clock rate CPUs.
Suggested answer: A, C

Explanation:

According to the CPU (%) - VMware Docs web search result2, one of the possible causes of high CPU ready % is over-provisioning vCPUs for a VM or having too many VMs on a host. CPU ready % indicates the percentage of time that the VM was ready, but could not get scheduled to run on the physical CPU. High CPU ready % can lead to VM performance problems, such as slow response time or application latency. To improve VM performance, the administrator should reduce the number of vCPUs assigned to VMs or reduce the number of VMs on the hosts, so that there is less contention for CPU resources.
