2V0-621 Question #241: Real Exam Question with Answer & Explanation
The correct answer is A: Remove the CPU limit on the vApp.. VM2's poor performance stems from CPU constraints at the vApp level and resource competition with VM1; removing limits or increasing VM2's reservation directly addresses these bottlenecks.
Question
An administrator has noticed that virtual machine VM2 in the vApp show in the Exhibit is demonstrating poor performance. Which three changes, if performed separately, would improve the performance of VM2? (Choose three.)
Exhibit
Options
- ARemove the CPU limit on the vApp.
- BRemove the CPU limit on the resource pool
- CIncrease the CPU reservation on virtual machine VM1.
- DPower off virtual machine VM1.
- EIncrease the CPU reservation on virtual machine VM2.
Explanation
VM2's poor performance stems from CPU constraints at the vApp level and resource competition with VM1; removing limits or increasing VM2's reservation directly addresses these bottlenecks.
Common mistakes.
- B. Removing the CPU limit on the resource pool addresses a different layer of the resource hierarchy and may not directly benefit VM2 if the binding constraint is the vApp-level CPU limit shown in the exhibit.
- C. Increasing the CPU reservation on VM1 guarantees more CPU for VM1, which reduces the pool of available CPU that VM2 can compete for, worsening rather than improving VM2's performance.
