A pharmaceutical company is storing highly sensitive patient data in Azure Blob Storage. Due to strict regulatory requirements, they must ensure that once a file is written, it cannot be modified or deleted for a specific retention period. Which Azure Blob Storage feature meets this requirement?
- AImmutable storage for Azure Blob Storage
- BSoft delete for blobs
- CAccess tiers (Hot, Cool, Archive)
- DBlob versioning
Show answer & explanationAnswer & explanation
Correct answer: A. Immutable storage for Azure Blob Storage
Immutable storage for Azure Blob Storage allows users to store business-critical data in a WORM (Write Once, Read Many) state. This means the data cannot be modified or deleted for a specified retention interval, meeting strict regulatory compliance needs.
Why the other options are wrong
- B. Soft delete for blobs allows recovery of deleted blobs, but does not prevent modification or deletion during a retention period.
- C. Access tiers relate to storage cost and performance based on access frequency, not immutability.
- D. Blob versioning keeps previous versions of a blob, but the current version can still be modified or deleted.
Immutable Storage for Azure Blob Storage
Immutable storage for Azure Blob Storage enables users to store business-critical data in a Write Once, Read Many (WORM) state. Data cannot be modified or deleted for a user-specified interval.
- Supports time-based retention and legal hold policies.
- Ensures data cannot be overwritten or deleted.
- Meets regulatory requirements (FINRA, SEC, HIPAA, etc.).
Memory trick: Immutable is Indelible.
