1Z0-1072-25 Question 240
Select 3Your IT department wants to maintain a complete history of file changes in an OCI Object Storage bucket while automatically archiving older versions to reduce storage costs. They plan to roll objects over to the Archive tier 30 days after they become previous versions and permanently delete them 90 days later. Which three steps must you take to achieve these requirements?
- A
Enable object versioning on the bucket.
- B
Configure a retention rule that locks all objects for 180 days.
- C
Create a lifecycle rule that transitions previous object versions to Archive 30 days after they become previous versions.
- D
Create a lifecycle rule that permanently deletes archived object versions 90 days after they have been in Archive.
- E
Enable client-side encryption to prevent accidental overwrites.
Show answer and explanation
Correct answers: A, C, D
Explanation
To maintain historical file versions, you first enable object versioning so that older versions aren�t overwritten. Then, to meet storage cost and data cleanup requirements, you create two lifecycle rules: one to transition older versions to Archive after 30 days, and another to permanently delete those archived versions after 90 days. Oracle documentation further explains that lifecycle policies can be combined with versioning to manage object data efficiently (see OCI Object Storage documentation on Versioning and Lifecycle Management).
- A. Correct.
Correct. Enabling object versioning ensures that all changes produce distinct versions, allowing old versions to remain available for lifecycle operations.
- B. Incorrect.
Incorrect. A retention rule of 180 days would block deletions until objects have reached 180 days of age, conflicting with the plan to delete them after 90 days in Archive tier. Retention rules also lock objects against deletion and overwrites for compliance or regulatory requirements, which is not asked for here.
- C. Correct.
Correct. You need a lifecycle rule to move older or previous versions into Archive after 30 days to reduce costs.
- D. Correct.
Correct. Deleting archived objects after 90 days meets the requirement to remove them once they are no longer needed. This second lifecycle rule complements the first, which archives them in a timely manner.
- E. Incorrect.
Incorrect. Client-side encryption is unrelated to the versioning and lifecycle management flow described. While encryption is a security best practice, it does not address the requirement for archiving and deleting older versions.
