1Z0-1072-25 Question 221
Single answerYou manage an Object Storage bucket in Oracle Cloud Infrastructure that stores monthly compliance logs. Your organization needs older versions of these logs retained for legal reasons but also wants to reduce costs for outdated versions. Which approach most effectively addresses both versioning and cost optimization?
- A
Enable bucket versioning and create a lifecycle policy that automatically transitions non-current versions to Archive Storage after a defined retention period.
- B
Enable client-side encryption to compress logs and reduce storage costs for previous versions of the data.
- C
Create a replicate rule to copy older log versions to a second bucket in a different region and delete them from the original bucket.
- D
Use Object Lock to prevent modifications on existing objects and rely on manual copy operations to move older versions into Archive Storage.
Show answer and explanation
Correct answer: A
Explanation
To retain and manage costs for older object versions, you should enable bucket versioning and then apply a lifecycle policy to transition obsolete or non-current versions to Oracle Archive Storage after the desired retention period. This feature set is detailed in Oracle's Object Storage documentation and best practices, ensuring compliance while minimizing long-term storage costs.
- A. Correct.
Correct. Bucket versioning maintains multiple object versions, and a lifecycle policy can automatically transition older (non-current) versions to Archive Storage after a specified time. This method lowers the storage costs while meeting legal retention requirements.
- B. Incorrect.
Incorrect. While encryption at rest or client-side encryption enhances data security, it does not by itself reduce Object Storage capacity costs for older file versions. Storage usage (and cost) remains the same regardless of encryption.
- C. Incorrect.
Incorrect. Replicating data to another region can help with disaster recovery or compliance but does not inherently reduce costs. It doubles storage usage if both copies must be retained.
- D. Incorrect.
Incorrect. Object Lock secures objects against deletion or overwriting but does not handle cost-optimization automatically. Manual processes to move older data can be error-prone and time-consuming.
