1Z0-1072-25 Question 212
Select 2Your company's finance department stores daily transaction receipts in an Object Storage bucket in the us-ashburn-1 region. To meet new compliance requirements, you set up a second bucket in the uk-london-1 region and configured cross-region replication. After creating a replication policy on the source bucket, you notice that newly uploaded objects are not appearing in the target bucket. Which two actions should you take to troubleshoot or fix the replication issue?
- A
Enable versioning on the source bucket and ensure it remains active.
- B
Create a life cycle rule to transition objects in the source bucket to the Archive tier.
- C
Make sure the replication policy is active and references the correct target bucket.
- D
Enable client-side encryption on all objects before uploading to the source bucket.
Show answer and explanation
Correct answers: A, C
Explanation
For cross-region replication of an Object Storage bucket in OCI, you must configure a replication policy in the source bucket and ensure versioning is enabled on that source bucket. The policy must be in 'Active' state and accurately reference the target bucket in the remote region. Additionally, you need appropriate IAM policies that allow replication operations. For further details, refer to the Oracle Cloud Infrastructure documentation on Object Storage cross-region replication (https://docs.oracle.com/en-us/iaas/Content/Object/Tasks/usingreplication.htm).
- A. Correct.
Option 1 is correct. Cross-region replication requires that the source bucket has versioning enabled. If versioning is disabled, the replication policy is effectively paused, preventing any data from replicating.
- B. Incorrect.
Option 2 is incorrect. Moving objects to the Archive storage tier on the source bucket can disrupt or delay cross-region replication, because Archive-tier objects cannot be immediately read or copied unless restored. This would not directly fix the replication issue.
- C. Correct.
Option 3 is correct. You must verify that the replication policy on the source bucket is in an 'Active' state and points to the correct destination bucket in the intended region. If the policy is inactive or points to the wrong bucket, no data will replicate.
- D. Incorrect.
Option 4 is incorrect. While encryption can be used for data protection, enabling client-side encryption is not mandatory for OCI's built-in cross-region replication to function. It has no direct role in fixing a lack of replicated objects.
