Question 1
Which rule in a virtual machine (VM) storage policy is configured to ensure data redundancy in a VMware vSAN environment?
- AOption A:
Failures to Tolerate
- BOption B:
Disk Stripes Per Object
- COption C:
Stripe Width
- DOption D:
Flash Read Cache Reservation
Show answer and explanation
Correct answer: A
The VM Storage Policy rule that controls data redundancy in vSAN is Failures to Tolerate (FTT) .
Defines the number of hardware failures (host, disk, network) that vSAN can tolerate while maintaining data availability.
Configurations include RAID-1 (mirroring) , RAID-5/6 (erasure coding) .
Other options:
B. Disk Stripes Per Object → Defines performance striping, not redundancy.
C. Stripe Width → Same as above, not redundancy.
D. Flash Read Cache Reservation → Relates to caching performance, not redundancy.
