All of the virtual machines running on a hybrid vSAN datastore have this storage policy assigned:
Failures to Tolerate (FTT) rule is set to ג€2 Failures - RAID-1 (Mirroring)ג€.

Which action should the vSAN administrator take to meet this goal?
- A. Change the FTT rule to ג€1 Failure - RAID-1 (Mirroring)ג€, and select ג€Nowג€ for Reapply to VMs.
- B. Add the ג€Flash read cache reservationג€ rule to the storage policy, and set to 0%.
- C. Disable Operations reserve and Host rebuild reserve and click ג€Applyג€.
- D. Modify the FTT rule to ג€2 Failures - RAID-5 (Erasure Coding)ג€.
