In a vSAN stretched cluster with Primary level to tolerate set to 1 and Secondary level of failure to tolerate set to 2, what is the maximum amount of space that a 100GB virtual disk could consume without any other policy rules set?
A. 200GB
B. 100GB
C. 400GB
D. 600GB

100GB disk. Apply the largest storage policy which would be RAID 1 and you get 200 GB, 100 GB on each side
looking just at the first side of the stretched cluster,
We apply the secondary failures to tolerate to 2. The two options would be RAID 1 again or RAID 6. Logically, RAID 1 would be the “largest” option. To tolerate 2 failures with RAID 1 you need 3 copies of the data so 100 GB becomes 300 GB.
That 300 GB is for a single side of the stretched cluster so we then x2 and we get 600 GB.
D is the correct answer.
C would be the answer if the secondary failures to tolerate was set to 1, which the question states its 2.
D ! 2 x 3 = 6 !
