1Z0-1123-25 Question 112
Select 2You have recently enabled cross-region replication on an Oracle Cloud Infrastructure (OCI) Object Storage bucket in your primary region to replicate to a secondary region for disaster recovery. However, you notice that objects uploaded before enabling the replication policy are not showing up in the target bucket. Which two actions would ensure these existing objects are also available in the target region?
- A
Perform a one-time Object Copy of all existing objects from the source bucket to the target bucket.
- B
Disable the replication policy, then re-enable it to force replication of existing objects.
- C
Re-upload the existing objects to the source bucket so they trigger replication to the target bucket.
- D
Wait for cross-region replication to synchronize all previously uploaded objects automatically.
Show answer and explanation
Correct answers: A, C
Explanation
OCI Object Storage cross-region replication only applies to new or updated objects after the replication policy is enabled. You must manually copy or re-upload any objects that existed prior to enabling replication. For more details, refer to Oracle Cloud Infrastructure documentation on Object Storage replication factors and the Object Copy feature.
- A. Correct.
Option 1: CORRECT. Cross-region replication only applies to objects uploaded or updated after replication is enabled. To move existing objects, you can perform an object copy from the source to the target region. This ensures all objects that existed before replication was enabled are copied over.
- B. Incorrect.
Option 2: INCORRECT. Temporarily disabling and re-enabling the replication policy does not force older objects to replicate. OCI replication policies do not retroactively replicate previously existing objects.
- C. Correct.
Option 3: CORRECT. Re-uploading (or re-writing) the existing objects in the source bucket effectively makes them 'new' objects, triggering replication to the target bucket. However, this may be less efficient than using an object copy for large numbers of objects.
- D. Incorrect.
Option 4: INCORRECT. By design, cross-region replication does not automatically synchronize objects that were already in the bucket prior to enabling the replication policy. Waiting will not cause older objects to appear in the target bucket.
