2V0-32.24 Question 204
Select 3You are a cloud administrator managing a VMware Cloud environment. Users have reported degraded performance for several virtual machines (VMs) running critical applications. Upon investigation, you notice high CPU Ready times and memory ballooning on the hosts. Which actions should you take to optimize performance in this scenario?
- A
Migrate VMs to hosts with lower utilization using vSphere DRS.
- B
Increase the CPU and memory reservations for the affected VMs.
- C
Enable vSAN deduplication and compression on the cluster to reduce storage latency.
- D
Verify overcommitment ratios and consolidate VMs onto fewer hosts.
- E
Right-size the affected VMs by reducing allocated vCPUs and memory to better match their usage.
Show answer and explanation
Correct answers: A, B, E
Explanation
High CPU Ready times and memory ballooning are signs of resource contention in a VMware Cloud environment. Distributing workloads using DRS, ensuring critical VMs have adequate reservations, and right-sizing over-allocated VMs are effective ways to resolve these issues. Enabling storage-specific features like deduplication won’t address CPU/memory contention, and consolidating VMs would exacerbate the problem.
- A. Correct.
Migrating VMs to hosts with lower utilization using vSphere DRS can help distribute workloads more evenly, reducing CPU Ready times and memory contention.
- B. Correct.
Increasing CPU and memory reservations for the affected VMs ensures they receive guaranteed resources, reducing contention and improving performance.
- C. Incorrect.
Enabling vSAN deduplication and compression is primarily a storage optimization and would not directly address CPU Ready times or memory ballooning.
- D. Incorrect.
Consolidating VMs onto fewer hosts would likely increase contention, worsening CPU Ready times and memory ballooning instead of alleviating them.
- E. Correct.
Right-sizing VMs by reducing over-allocated resources can help optimize resource usage across the cluster, leading to improved performance.
