When configuring Erasure Coding on a vSAN stretched cluster, the appropriate RAID level to specify would be RAID 5/6. The Failures to Tolerate (FTT) setting should be set to SFTT (Secondary Failures to Tolerate) because SFTT applies to failures within each site of the stretched cluster. Therefore, the correct combination is SFTT with RAID 5/6.
My Answer is D. Primary Failures to Tolerate (PFTT) defines the number of sites that can accept failure, typically ranging from 0 to 1. PFTT ensures a copy of the data is available in both locations in a stretched cluster. Secondary Failures to Tolerate (SFTT) is a rule that applies to tolerate the failures within each site of a stretched cluster. SFTT can be seen as host failures, and you can define the tolerable number accordingly http://vcallaway.com/vsan-specialist-6-3-understand-data-placement-in-a-stretched-cluster/
