Which Azure storage feature should an architect recommend to protect Azure Blob Storage data from accidental deletion AND retain prior versions for a configurable retention period?
AAzure DNS
BAzure Cache for Redis
CManual quarterly snapshots to a USB drive
DSoft delete + blob versioning (combined with immutable storage policies for compliance retention)
Answer & Solution
Correct answer: D. Soft delete + blob versioning (combined with immutable storage policies for compliance retention)
Soft delete + versioning + immutability are Azure's blob data-protection stack (per AZ-305 §3 unstructured backup). The other options are anti-patterns or unrelated.
