1Z0-1072-25 Question 211
Single answerYour organization stores critical compliance logs in an Object Storage bucket in the Phoenix region. They require these logs to be automatically replicated to a bucket in the Ashburn region for regulatory compliance and long-term retention. Which configuration would enable automatic cross-region replication while preserving file versions with minimal operational overhead?
- A
Create a replication policy on the source bucket in Phoenix and enable bucket versioning, specifying the target bucket in Ashburn.
- B
Set up a pre-authenticated request on the Phoenix bucket and manually copy objects to the Ashburn bucket every week.
- C
Use the Data Transfer Appliance service to physically move the data from Phoenix to Ashburn on a quarterly schedule.
- D
Configure Archive Storage as a second-tier for storing logs locally in the Phoenix region and periodically replicate them via a custom script.
Show answer and explanation
Correct answer: A
Explanation
Cross-region replication in OCI Object Storage is best achieved by creating replication policies on the source bucket and enabling versioning for compliance requirements. These policies asynchronously copy objects to the target bucket in another region, eliminating the need for manual transfers or external appliances. Refer to the official OCI documentation (Object Storage Cross-Region Replication Guide) for step-by-step instructions and best practices.
- A. Correct.
Option 1 is correct. To configure cross-region replication for Object Storage logs, you create a replication policy on the source bucket in Phoenix. Enabling versioning ensures older file versions are preserved. This is an asynchronous process managed by OCI, requiring minimal hands-on maintenance.
- B. Incorrect.
Option 2 is incorrect. Pre-authenticated requests allow temporary secure access to a bucket but do not automatically replicate objects. Manual processes introduce operational overhead and are prone to failures or delays.
- C. Incorrect.
Option 3 is incorrect. The Data Transfer Appliance is typically used for large one-time migrations or offline data transport, not for continuous replication. It wouldn't provide automated ongoing replication.
- D. Incorrect.
Option 4 is incorrect. Archive Storage is a low-cost, long-term storage option but does not provide built-in cross-region replication. Manually replicating via scripts adds complexity and maintenance overhead.
