What is a prerequisite for unmounting the datastore?
The correct prerequisite for unmounting a datastore is that the datastore is NOT managed by Storage DRS. If a datastore is managed by Storage DRS, it means that the system automatically balances storage resources to ensure optimal performance and capacity utilization. Therefore, unmounting a datastore managed by Storage DRS could disrupt these automated processes. This makes it necessary to ensure that Storage DRS does not manage the datastore before attempting to unmount it.
According to the listed KB, both A and B are prerequisites for removing a datastore...
When appropriate, before unmounting datastores, make sure that the following prerequisites are met: - No virtual machines reside on the datastore. - Storage DRS does not manage the datastore. - Storage I/O Control is disabled for this datastore https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-1B56EF97-F60E-4F21-82A7-8F2A7294604D.html
The datastore is not managed by Storage DRS. No virtual machines reside on the datastore ( Power-On VMs Not Powerd-Off)
I think the key word is prerequisite. One could not unmount the datastore if it is managed by Storage DRS. You could still remove the datastore if it was configured for HA Heartbeating, was referenced in a host profile and contained power-off VMs
If VMs will be registered, you'll not be able to unmount datastove, even if VM is powered off.
Took the exam today, it is a single answer question, went for A.

Storage DRS does not manage the datastore. Storage I/O Control is disabled for this datastore. Thus, A & D.
To unmount a datastore > No VMs running on the datastore > No DRS managment > No storage I/O control https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-1B56EF97-F60E-4F21-82A7-8F2A7294604D.html
A is Correct
D looks also a good one: If the LUN is being used as a VMFS datastore, all objects (for example, virtual machines, templates, and Snapshots) stored on the VMFS datastore must be unregistered or moved to another datastore. All CD/DVD images located on the VMFS datastore must also be unmounted/unregistered from the virtual machines. The datastore is not used for vSphere HA heartbeat. The datastore is not part of a datastore cluster. The datastore is not managed by Storage DRS.
AAA - https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-1B56EF97-F60E-4F21-82A7-8F2A7294604D.html
Correct answer is A, B, and D. The question is not worded correctly, but if taking the exam you are given the option to select more then 1 right answer

This question is quite silly. I totally agree it should be both storage DRS and HA heartbeat.
This should be a multiple-option question I agree with dbbb111
