Box 1: Standard general-purpose v2
Standard general-purpose v2 supports immutable storage.
In general Standard general-purpose v2 is the preferred Microsoft recommendation.
Box 2: Zone-redundant storage (ZRS)
ZRS is more resilient compared to LRS.
Note: RA-GRS is even more resilient, but it is not an option here.
