When attempting to place a datastore in Maintenance Mode, the task remains at 1%. What are two potential causes for this? (Choose two.)

If Storage DRS is disabled on a specific VM disk via per-VM Storage DRS overrides, vSphere cannot generate a migration recommendation for that disk, leaving it stranded on the datastore and preventing Maintenance Mode from completing.

Storage DRS affinity or anti-affinity rules can prohibit the migration of specific disks to other datastores, causing the Maintenance Mode evacuation task to stall because no valid placement can be recommended.

Insufficient space on other datastores would cause migration attempts to fail after recommendations are generated, not cause the task to hang at 1% before any migrations are attempted.

I/O control policies on the provisioning network throttle I/O bandwidth but do not block Storage DRS from generating or executing datastore migration recommendations.
