Question #: 4
Topic #: 1

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?

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.

Answer is D: Since the VMs are not memory intensive, moving the swap file to a non flash array datastore helps to free-up space in the flash array, there by the space is effectively used. https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.resmgmt.doc/GUID-2A031EBB-BEBA-4DDE-BEA1-B8062974806E.html

As the applications are not memory intensive there will be very less utilization of swap memory. So admin can move swap space to cheaper disks rather than in flash
