    CASE STUDY: HealthData Inc

    Requirements:

    Tech Reqs:

    • Strict HIPAA compliance

    • Network isolation (no public internet)

    Constraints:

    • US data sovereignty
    • 7-year retention (immutable)
    • Easy auditor access

    QUESTION: To meet the 7-year immutable data retention requirement for patient records, how should you configure Cloud Storage?

    Answer options:

    A.

    Enable Object Versioning and set a lifecycle rule to delete objects after 7 years.

    B.

    Apply a Bucket Lock with a retention policy of 7 years.

    C.

    Use Customer-Managed Encryption Keys (CMEK) and rotate the keys every 7 years.

    D.

    Store the data in the Archive storage class.

    How to approach this question

    Identify the Cloud Storage feature that enforces WORM (Write Once, Read Many) compliance.

    Full Answer

    B.Apply a Bucket Lock with a retention policy of 7 years.✓ Correct
    Cloud Storage Bucket Lock allows you to enforce minimum retention periods for objects. Once a retention policy is locked, it cannot be reverted, and objects cannot be deleted or overwritten until their retention period (e.g., 7 years) expires. This is required for strict regulatory compliance.

    Common mistakes

    Choosing Object Versioning (A), which protects against accidental deletion but does not satisfy legal immutability requirements.
