Question
Which two statements are true regarding Virtual SAN Fault Domains? (Choose two.)
Options
- AThey enable Virtual SAN to tolerate the failure of an entire physical rack.
- BVirtual SAN ensures that no two replicas are provisioned on the same domain.
- CVirtual SAN ensures that all replicas are provisioned on the same domain.
- DThey require VMware High Availability (HA) to ensure component distribution across domains.
Explanation
vSAN Fault Domains protect against rack-level failures by ensuring that replicas of any object are always placed in different fault domains.
Common mistakes.
- C. Placing all replicas in the same fault domain is the opposite of the intended behavior and would mean a single rack failure destroys every copy of the data, completely negating the protection that fault domains are designed to provide.
- D. VMware HA is not required for vSAN Fault Domain functionality; vSAN's own storage policy engine independently governs component placement across fault domains without any dependency on HA being enabled.
