Which two reasons would prevent Storage Distributed Resource Scheduler (SDRS) from operating on a datastore? (Choose two.)
The correct answer is A. The datastore has Storage I/O Control disabled. B. The datastore is connected to an unsupported host.. SDRS requires Storage I/O Control to be enabled and all connected hosts to be supported in order to manage a datastore cluster.

Why each option
SDRS requires Storage I/O Control to be enabled and all connected hosts to be supported in order to manage a datastore cluster.
SDRS uses Storage I/O Control (SIOC) to measure and balance I/O load across datastores. If SIOC is disabled on a datastore, SDRS cannot collect the latency and throughput statistics it needs, preventing I/O-based load balancing recommendations.
SDRS requires that every host connected to a datastore in a datastore cluster be a supported host version. An unsupported or incompatible host prevents SDRS from managing migrations and recommendations for that datastore.
SDRS supports NFS datastores, so hosting a datastore on an NFS server does not prevent SDRS from operating on it.
SDRS supports iSCSI-based datastores, so an iSCSI-hosted datastore is fully compatible with SDRS operation.
