- CThe VMDK is hosted on NFS storage.
- DThe virtual machine has a CD-ROM/ISO image connected.
Explanation
Storage DRS automates VMDK placement and migration within a datastore cluster, but it cannot manage all disk types. (A) Independent disks are virtual disks explicitly configured to be unaffected by snapshots. Storage DRS relies on the ability to take snapshots as part of its Storage vMotion workflow; because independent disks are excluded from snapshot operations, Storage DRS is automatically disabled for them. (B) vSphere Fault Tolerance (FT) requires the primary and secondary VM to have their virtual disks on the exact same datastore so that the lockstep replication mechanism works correctly. If Storage DRS were to migrate one VM's disk independently, it would break FT's tight coupling requirement. Therefore, Storage DRS is disabled for any VMDK belonging to an FT-enabled VM. Option C is incorrect because Storage DRS does support NFS datastores (all datastores in a datastore cluster must be of the same type, but NFS alone does not disable SDRS per-VMDK). Option D is incorrect because a connected CD-ROM or ISO image has no bearing on whether Storage DRS can manage the VM's virtual hard disks.
