VCP-VCF Administrator 2024 Question 372
Select 3As a VMware Cloud Foundation administrator, you notice that a workload domain is experiencing resource contention due to overcommitment of CPU and memory resources. To optimize resource allocation and utilization, which actions should you take to ensure efficient operation?
- A
Adjust the resource pools to set appropriate limits and shares for critical workloads.
- B
Increase the vSphere HA admission control policy thresholds to allow more VMs to run simultaneously.
- C
Use vRealize Operations Manager to identify underutilized VMs and right-size them based on actual usage.
- D
Enable DRS (Distributed Resource Scheduler) in aggressive mode to improve workload balancing across the cluster.
- E
Disable vMotion to reduce resource contention caused by live migrations.
Show answer and explanation
Correct answers: A, C, D
Explanation
To optimize resource allocation and utilization, administrators should take actions that improve workload prioritization (such as adjusting resource pools), reclaim unused resources (using tools like vRealize Operations Manager), and enable automated load balancing (like DRS in aggressive mode). These steps collectively ensure efficient operation and reduce resource contention.
- A. Correct.
Adjusting resource pools with appropriate limits and shares ensures critical workloads have the necessary resources during contention periods, improving resource allocation.
- B. Incorrect.
Increasing the vSphere HA admission control policy thresholds may lead to insufficient resources being available during a host failure, exacerbating the contention issue.
- C. Correct.
Using vRealize Operations Manager for right-sizing allows you to reclaim resources from underutilized VMs, optimizing overall resource utilization.
- D. Correct.
Enabling DRS in aggressive mode helps balance workloads more effectively across the cluster, reducing contention and improving efficiency.
- E. Incorrect.
Disabling vMotion would inhibit the ability to dynamically balance workloads across hosts, which is counterproductive to resolving resource contention.
