Question 153 - NCP-MCI-6.5 discussion

Report
Export

An administrator responsible for a VDl environment needs to investigate reports of slow logins. The administrator finds that increasing the number of vCPUs from 2 to 4 will reduce the login times. Production workloads are consuming 75% of the host CPU on the cluster. The administrator increases the vCPU count on all of the VDl VMs.

What are two impacts on the cluster? (Choose two)

A.
Increasing CPU counts will decrease memory utilization
Answers
A.
Increasing CPU counts will decrease memory utilization
B.
Increase memory utilization%
Answers
B.
Increase memory utilization%
C.
Increase CPU utilization%
Answers
C.
Increase CPU utilization%
D.
Increase CPU ready%
Answers
D.
Increase CPU ready%
Suggested answer: C, D

Explanation:

According to the web search results, the two impacts on the cluster that will result from increasing the vCPU count on all of the VDI VMs are:

Increase CPU utilization%: CPU utilization is the percentage of time that a CPU is busy executing instructions5.By increasing the vCPU count on all of the VDI VMs, the administrator will increase the demand for CPU resources on the cluster, which will increase the CPU utilization percentage6.

Increase CPU ready%: CPU ready is the percentage of time that a vCPU is ready to run but is waiting for a physical CPU to become available5.By increasing the vCPU count on all of the VDI VMs, the administrator will increase the contention for physical CPU resources on the cluster, which will increase the CPU ready percentage6.A high CPU ready percentage can indicate performance issues such as latency or slowdowns5.
