2V0-32.24 Question 131
Select 4A VMware vSphere environment is experiencing intermittent performance issues. The administrator notices that virtual machines (VMs) running on a specific ESXi host are affected. Upon further investigation, the administrator identifies a high percentage of CPU Ready (%RDY) time on the VMs hosted on that ESXi host. Which of the following troubleshooting steps should the administrator take to resolve the issue?
- A
Check the CPU overcommitment ratio on the affected ESXi host and reduce the number of vCPUs assigned to the VMs.
- B
Verify if there are any CPU affinity rules configured and remove them if they are unnecessarily restricting CPU resources.
- C
Increase the memory allocation for the affected VMs to reduce CPU contention.
- D
Migrate some of the VMs to another ESXi host using vMotion to balance the workload.
- E
Enable hyper-threading on the ESXi host to increase CPU resource efficiency if it is not already enabled.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
High CPU Ready (%RDY) time typically indicates CPU resource contention, often caused by overcommitment or restrictive policies. To address this, the administrator should focus on redistributing CPU workloads (e.g., reducing vCPU assignments, removing affinity rules, migrating VMs) and optimizing CPU utilization (e.g., enabling hyper-threading). Increasing memory allocation does not directly address CPU contention and is not relevant for this issue.
- A. Correct.
High %RDY time often indicates CPU overcommitment. Reducing the number of vCPUs assigned to VMs can help redistribute CPU resources more effectively and reduce contention.
- B. Correct.
CPU affinity rules can bind VMs to specific CPUs, which might restrict their ability to utilize available CPU resources. Removing unnecessary CPU affinity rules can alleviate the issue.
- C. Incorrect.
Increasing memory allocation does not directly address CPU contention or high %RDY time. This option is not relevant in this situation.
- D. Correct.
Migrating some of the VMs to another ESXi host using vMotion can help distribute the CPU workload more evenly and reduce contention on the affected host.
- E. Correct.
Hyper-threading can increase the efficiency of CPU utilization and may help reduce CPU Ready time if it is not already enabled.
