Actual exam question from VMware's 2V0-21.19

Question #: 101
Topic #: 1

An application owner complains about poor performance on a VM named APPVM01. Troubleshooting indicates that another VM named DBVM01 on the same datastore is saturating the volume with I/O requests.
Which two actions can be taken to reduce DBVM01 impact on APPVM01, while still prioritizing DBVM01 disk I/O? (Choose two.)

A. Configure APPVM01 with a shares limit of Low, and DBVM01 with a shares limit of Normal
B. Enable Network I/O Control on the cluster containing APPM01 and DBVM01
C. Enable Storage I/O Control on the cluster containing APPVM01 and DBVM01
D. Enable Storage I/O Control on the datastore containing APPM01 and DBVM01
E. Configure APPVM01 with a shares limit of High, and DBVM01 with a shares limit of Normal

Correct Answer is: A,D Questions reads as: "while still prioritizing DBVM01 disk I/O". It means DBVM01 should still need high I/O but at the same time it should not monopoly the bandwidth. Hence the share limit is set with APPVM01 Low and DBVM01 High. This helps APPVM01 to receive half the I/O of DBVM01 at the time of contention, hence there is no performance impact.

how do you know DBVM01 needs more I/Ops than APPVM01 as provided in answer A? It doesn't state that in the question.

DB VMs always consume more I/O resources that APPs.

It can't be D. That is not the name of the original VM.

it is a mistype the correct answer is 1(A) Configure APPVM01 with a shares limit of Low, and DBVM01 with a shares limit of Normal 2(D) Enable Storage I/O Control on the datastore containing APPVM01 and DBVM01 why the question ask you to reduce DBVM01 impact on APPVM01, while still prioritizing DBVM01 disk I/O so DBVM01 with a shares limit of Normal (make sure it have more IO normal is 1000) and APPVM01 with a shares limit of Low (make sure it have some IO low is 500 iops it more then an app server need ) https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.resmgmt.doc/GUID-BB7458A8-0CB6-4733-A168-A6B0C6268009.html https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.resmgmt.doc/GUID-25C3D9FE-3A9D-4739-AC75-16A9E0A3D9F0.html https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.resmgmt.doc/GUID-7686FEC3-1FAC-4DA7-B698-B808C44E5E96.html

A and D is correct. Storage IO control is per datastore and not per cluster. https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.resmgmt.doc/GUID-BB5D9BAB-9E0E-4204-A76A-54634CD8AD51.html
