1Z0-1123-25 Question 111
Single answerYou work for a global logistics company that needs to replicate large objects from a source bucket in one region to a destination bucket in another region for redundancy. After enabling bucket versioning on the source bucket, you notice that objects are still not replicating automatically to the destination. What is the most appropriate next step to ensure successful cross-region replication?
- A
Create and apply a replication policy on the source bucket to specify the target bucket and region.
- B
Manually copy each object using the Oracle Cloud Infrastructure CLI to push objects to the destination bucket.
- C
Disable versioning on both buckets and then re-upload all objects to initiate replication.
- D
Enable Archive Storage on the target bucket to reduce storage costs and enable replication simultaneously.
Show answer and explanation
Correct answer: A
Explanation
OCI Object Storage cross-region replication requires versioning to be enabled on the source bucket and a replication policy specifying the destination bucket. Once configured, any new or updated objects in the source bucket replicate automatically to the target. Manual tasks, such as using the CLI or disabling versioning, are either inefficient or prevent replication from functioning. Refer to the Oracle Cloud Infrastructure documentation for detailed steps on creating replication policies, managing IAM permissions, and configuring bucket versioning (https://docs.oracle.com/en-us/iaas/Content/Object/Tasks/usingreplication.htm).
- A. Correct.
Option 1 is correct. After enabling versioning on the source bucket, you must create a replication policy that defines where and how the objects should be replicated. This policy, combined with the appropriate IAM settings, ensures automatic, asynchronous replication to the target bucket in the specified region.
- B. Incorrect.
Option 2 is incorrect because manually copying each object does not leverage OCI's automated replication features. While the CLI can be used to copy objects, it is neither an efficient nor a scalable approach for continuous replication.
- C. Incorrect.
Option 3 is incorrect because disabling versioning on both buckets will prevent the use of cross-region replication entirely. Replication requires versioning to be enabled on the source bucket. Simply disabling and re-uploading does not automatically replicate objects across regions.
- D. Incorrect.
Option 4 is incorrect because enabling Archive Storage does not, by itself, enable replication. Archive Storage is a lower-cost tier designed for infrequent access, and replication policies must still be configured separately.
