1Z0-1072-25 Question 228
Single answerYou are a solutions architect at a financial institution needing to retain historical transaction records for seven years due to regulatory requirements. These records are rarely accessed after the first few weeks. Your goal is to minimize storage costs while still being able to retrieve data when needed. Which approach in Oracle Cloud Infrastructure best meets these requirements?
- A
Store all transaction records in the Standard tier and apply a retention policy to prevent deletions for seven years.
- B
Store the records directly in the Archive tier and automatically restore them to the Standard tier every week for compliance checks.
- C
Store the records in the Standard tier for 30 days, then use a Lifecycle Policy to transition them to the Archive tier for the rest of the retention period.
- D
Create multiple Standard buckets in different compartments to minimize cost across various usage patterns.
Show answer and explanation
Correct answer: C
Explanation
Storing data that is infrequently accessed in the Archive tier significantly reduces long-term storage costs in Oracle Cloud Infrastructure. A lifecycle management policy allows automatically transitioning data from Standard to Archive after a defined period, typically once it is no longer actively used. If access is needed, data can be restored from the Archive tier by initiating a restore job, which then temporarily makes the data accessible in the Standard tier. For more details, consult the official Oracle Cloud Infrastructure documentation on Object Lifecycle Management.
- A. Incorrect.
Option A is incorrect because keeping data in the Standard tier for the entire seven-year period is more expensive, especially for rarely accessed files. Although it meets retention requirements, it does not minimize cost effectively.
- B. Incorrect.
Option B is incorrect as automatically restoring records to Standard on a weekly schedule defeats the purpose of using Archive for cost savings. If the data is rarely accessed, frequent restores are unnecessary and add complexity and cost.
- C. Correct.
Option C is correct. A common best practice is to keep recent data in the Standard tier for short-term access, then use Object Lifecycle Management to transition older, rarely accessed data to the Archive tier, reducing storage costs. Data from Archive can still be restored if needed.
- D. Incorrect.
Option D is incorrect because simply creating multiple Standard buckets in different compartments does not reduce storage costs. All data is still billed at the Standard rate, and moving it between identical tiers does not produce cost savings.
