VMware vSphere 7.x Professional (VCP-DCV 2021) — Question 111

An administrator runs a vSphere cluster containing database VMs with extremely heavy disk I/O. Database VMs are placed on a costly all-flash array. The workloads are not memory intensive.
How can the administrator ensure the most cost-effective utilization of the all-flash storage array?

Answer options

• A. Enable Storage I/O Control on the flash datastores.
• B. Install VMware Tools on the database VMs to ensure the hypervisor can receive I/O metrics.
• C. Use a VM-to-Host affinity rule to ensure database VMs are prioritized.
• D. Edit the cluster settings to place the virtual machine swap file on a different storage tier.

Correct answer: D

Explanation

The correct answer is D because relocating the swap file can reduce the overall demand on the high-cost all-flash storage, allowing for more efficient use of resources. Options A, B, and C do not directly address the cost-effectiveness of storage usage, as they focus on performance or prioritization without optimizing the storage costs.
