1Z0-1072-25 Question 183
Single answerYour organization stores large historical log files in Oracle Cloud Infrastructure (OCI) for compliance audits. These logs are rarely accessed, but you must retain the ability to retrieve them within hours for an occasional review. Given a requirement to minimize storage costs while retaining retrieval flexibility, which solution should you implement?
- A
Use Object Storage in the Standard tier and configure a lifecycle policy to move older data to the Archive tier
- B
Deploy File Storage service with maximum performance for all logs
- C
Attach Block Volumes to a stopped Compute instance to reduce costs
- D
Store logs in the Archive tier only if they exceed 10 TB in size
Show answer and explanation
Correct answer: A
Explanation
In OCI, using Object Storage lifecycle policies to seamlessly transition data from the Standard tier to the Archive tier is a recommended approach for infrequently accessed data. The Archive tier provides a lower storage cost while still allowing data retrieval within hours, making it suitable for compliance logs that are seldom accessed but must remain retrievable. Refer to OCI Object Storage documentation for guidance on lifecycle policy configuration and cost considerations.
- A. Correct.
Option 1 (Correct): Storing data in the Standard tier for initial use, then applying a lifecycle policy to automatically move older data to the Archive tier ensures minimal storage costs and allows retrieval within hours. Archive tier retrieval times are longer than Standard, but still meet occasional review needs. This is a best-practice approach in OCI for balancing cost and retrieval requirements.
- B. Incorrect.
Option 2: While File Storage supports high-performance operations, it is typically more expensive than Object Storage. This option does not align with a cost-optimization strategy for largely inactive log files.
- C. Incorrect.
Option 3: Keeping logs in Block Volumes attached to a stopped Compute instance is still significantly more expensive than using Object Storage. Block Volumes are better suited for persistent storage attached to active workloads, not archival.
- D. Incorrect.
Option 4: OCI Archive Storage does not mandate moving logs only if they are above a certain size (e.g., 10 TB). The decision to use the Archive tier is driven by access frequency and cost considerations, not a strict size threshold.
