Which two statements are true regarding Virtual SAN Fault Domains? (Choose two.)

A.
They enable Virtual SAN to tolerate the failure of an entire physical rack.

B.
Virtual SAN ensures that no two replicas are provisioned on the same domain.

C.
Virtual SAN ensures that all replicas are provisioned on the same domain.

D.
They require VMware High Availability (HA) to ensure component distribution across domains.

Explanation:

A fault domain consists of one or more Virtual SAN hosts grouped together according to their physical location in the data center. When configured, fault domains enable Virtual SAN to tolerate failures of entire physical rack as well as failures of a single host, capacity device, network link or a network switch dedicated to fault domains.
Fault domains cannot be configured for stretched or metro clusters.
