1Z0-1067-25 Question 88
Single answerYour organization must retain critical application logs for 7 years to meet compliance requirements. These logs are rarely accessed after the first month, and during the retention period, they cannot be overwritten or deleted. Which approach should you use to implement a cost-efficient retention strategy in Oracle Cloud Infrastructure?
- A
Create a Standard tier bucket without a lifecycle policy and manually move the logs after 7 years.
- B
Set up an Archive tier bucket with an Object Lock retention rule set to 7 years, and use lifecycle policies to move logs from Standard to Archive after 30 days.
- C
Deploy ephemeral storage on compute instances for immediate log access and manually copy data to other storage as needed.
- D
Store logs in Block Volumes, taking monthly snapshots and retaining them for 7 years.
Show answer and explanation
Correct answer: B
Explanation
A well-structured data retention strategy in OCI typically involves using Object Storage with lifecycle rules and Object Lock to automatically transition data to the Archive tier and enforce retention requirements. By setting a retention rule and leveraging the Archive tier, organizations ensure logs are protected against accidental or premature deletion, while also minimizing storage costs. Refer to OCI documentation on Object Storage, Object Lock, and data lifecycle management for best practices and configuration details.
- A. Incorrect.
Option 1 is incorrect. Relying on manual moves after 7 years is error-prone and does not enforce retention or prevent accidental deletion. It also doesn't ensure cost savings during the interim period.
- B. Correct.
Option 2 is correct. Archive tier is a cost-effective storage option for infrequently accessed data, and using Object Lock enforces retention so logs cannot be deleted before 7 years. Lifecycle policies automate the transition after 30 days of infrequent usage, optimizing costs.
- C. Incorrect.
Option 3 is incorrect. Ephemeral storage is designed for short-term use and does not offer the durability or automated retention controls required. It also risks data loss if the instance is stopped or fails.
- D. Incorrect.
Option 4 is incorrect. Storing logs on Block Volumes and manually managing snapshots over 7 years increases administrative overhead and costs, and does not provide a native mechanism to lock data from deletion.
