CV0-003 Question #87: Real Exam Question with Answer & Explanation
The correct answer is C: Allocate more memory to the affected users' virtual desktops and the database desktops. Database processing VMs periodically consuming large amounts of resources cause contention that degrades performance for other users on the same resource pool, and the best remedy is ensuring all affected VMs have sufficient memory allocated to avoid resource competition.
Question
Options
- AEnable memory ballooning on the hypervisors supporting the database desktops
- BEnable I/O throttling on the hypervisors supporting the database desktops
- CAllocate more memory to the affected users' virtual desktops and the database desktops
- DAllocate more CPU resources to the affected users' virtual desktops
Explanation
Database processing VMs periodically consuming large amounts of resources cause contention that degrades performance for other users on the same resource pool, and the best remedy is ensuring all affected VMs have sufficient memory allocated to avoid resource competition.
Common mistakes.
- A. Enabling memory ballooning causes the hypervisor to reclaim memory from VMs and would worsen resource contention during peak database processing periods, not improve it.
- B. Enabling I/O throttling on the database desktops would limit their disk throughput but does not address memory contention, which is the primary resource driver for database workloads.
- D. Allocating more CPU to affected users' desktops targets only CPU resources and does not address the broader memory and resource contention caused by the periodic database processing runs.
