1Z0-1072-25 Question 239
Select 3Your organization needs to store critical documents in an OCI Object Storage bucket. Regulations require that objects cannot be deleted or overwritten for at least 90 days, and older object versions should be moved to the Archive tier after 30 days to reduce cost. Which three steps must you take to meet these requirements?
- A
Enable Object Versioning on the bucket.
- B
Create a bucket-level retention rule enforcing a 90-day Write-Once-Read-Many (WORM) period.
- C
Configure a Lifecycle policy to transition noncurrent object versions to the Archive tier after 30 days.
- D
Use the default Storage tier so that OCI automatically archives older versions.
- E
Add a dynamic group security policy that denies delete operations on the bucket.
Show answer and explanation
Correct answers: A, B, C
Explanation
To meet compliance and cost requirements, you must first enable Object Versioning so previous versions are retained. Next, configure a retention rule (often referred to as WORM) on the bucket to hold objects for the required 90-day period. Finally, use an Object Storage Lifecycle policy to automatically transition older (noncurrent) object versions to the Archive tier after 30 days. Refer to the Oracle Cloud Infrastructure documentation on Object Versioning, Retention Rules, and Lifecycle Policies for detailed setup instructions.
- A. Correct.
Correct. Enabling Object Versioning is necessary to keep all object versions and ensure older versions aren�t deleted or overwritten immediately.
- B. Correct.
Correct. A retention rule with a 90-day WORM setting prevents objects from being deleted or overwritten during the compliance period.
- C. Correct.
Correct. A Lifecycle policy moves noncurrent versions (i.e., older versions of objects) to the Archive tier after 30 days, lowering storage costs.
- D. Incorrect.
Incorrect. Relying on the default Storage tier alone does not automatically archive older object versions. A Lifecycle policy is needed for archiving.
- E. Incorrect.
Incorrect. While a security policy could block deletes, it doesn�t implement the required 90-day retention period nor does it archive objects after 30 days.
