VCP-VCF Administrator 2024 Question 145
Single answerYou are a VMware Cloud Foundation Administrator and have been tasked with resolving a performance issue reported by users running critical workloads on a specific virtual machine (VM). Upon investigation in VMware vCenter, you notice the VM is experiencing CPU contention. What is the most appropriate Day 2 operation to mitigate the issue?
- A
Increase the number of virtual CPUs (vCPUs) assigned to the virtual machine.
- B
Migrate the virtual machine to a host with lower CPU usage using vSphere vMotion.
- C
Reduce the Memory Reservation on the virtual machine to free up resources for other VMs.
- D
Enable vSphere DRS in fully automated mode to balance the workload across the cluster.
Show answer and explanation
Correct answer: B
Explanation
The best solution to resolve the immediate CPU contention issue is to migrate the VM to a host with lower CPU utilization using vSphere vMotion. This ensures the VM can access sufficient compute resources without impacting other VMs. While other options might have long-term benefits or address other issues, they do not directly resolve the reported CPU contention.
- A. Incorrect.
Increasing the number of vCPUs may worsen the issue as it increases CPU scheduling contention, especially in overcommitted environments.
- B. Correct.
Migrating the virtual machine to a host with lower CPU usage is an effective method to address CPU contention, as it ensures the VM gets access to more physical CPU resources.
- C. Incorrect.
Reducing the Memory Reservation does not address CPU contention and may instead negatively impact the memory allocation of the VM.
- D. Incorrect.
Enabling vSphere DRS in fully automated mode is a proactive measure but does not address the immediate CPU contention issue for this VM.
