1Z0-1123-25 Question 114
Single answerYour team needs to create an offsite disaster recovery copy of an existing bucket in Region A by replicating it to a new bucket in Region B. They want to ensure that all existing objects are immediately available in Region B, and that any newly uploaded objects to Region A continue to be replicated automatically to Region B. Which approach satisfies these requirements?
- A
A. Enable object replication between the existing bucket in Region A and the new bucket in Region B. This automatically copies all existing objects and any new objects going forward.
- B
B. First use Object Copy to transfer existing objects to the target bucket in Region B, then configure object replication between the two buckets to handle new uploads.
- C
C. Configure object replication on both buckets with versioning disabled to ensure a full sync of existing and new objects in real time.
- D
D. Create a custom replication policy with a one-time backfill job to migrate old objects, followed by a continuous policy for new objects in the same policy configuration.
Show answer and explanation
Correct answer: B
Explanation
Object replication in Oracle Cloud Infrastructure is designed to replicate new or updated objects once the policy is in place. To replicate existing (pre-policy) objects, you must manually copy them or re-upload them to the source bucket after enabling replication. The standard approach is to first copy existing objects using the Object Copy feature, and then configure replication so that any new uploads or updates are automatically synced. Refer to the official OCI documentation on Object Storage replication for detailed steps and best practices: https://docs.oracle.com/en-us/iaas/Content/Object/Tasks/replicatingobjects.htm.
- A. Incorrect.
Option A: Incorrect. Object replication only replicates new or updated objects once configured. Existing objects are not automatically replicated unless you manually copy them first or re-upload them.
- B. Correct.
Option B: Correct. A common best practice is to use Object Copy to migrate existing data, then enable object replication so new or updated objects continue to sync to the target bucket automatically.
- C. Incorrect.
Option C: Incorrect. Object replication requires versioning to be enabled on both source and target buckets. Disabling it prevents changes from being tracked properly, and it will not perform a full initial sync of existing data.
- D. Incorrect.
Option D: Incorrect. OCI does not provide a one-time backfill job as part of a single replication policy. A separate process (Object Copy or other data transfer) must be used for existing objects.
