1Z0-1072-25 Question 215
Single answerYou have an existing OCI Object Storage bucket named 'prod-logs-bucket' in the Phoenix region, and your organization wants to replicate newly uploaded log files to a bucket in the Ashburn region for disaster recovery. You have created a new Ashburn bucket named 'dr-logs-bucket.' Which step is required to configure automatic cross-region replication from Phoenix to Ashburn?
- A
Enable replication at the load balancer level to forward logs from the Phoenix region to Ashburn.
- B
Create a replication policy on 'prod-logs-bucket' referencing 'dr-logs-bucket' in Ashburn, and ensure appropriate IAM policies are configured.
- C
Leverage the 'export to object storage' feature in the console to periodically transfer new data to the Ashburn bucket.
- D
Create a pre-authenticated request to 'prod-logs-bucket' and schedule a daily job to copy objects to 'dr-logs-bucket'.
Show answer and explanation
Correct answer: B
Explanation
To configure cross-region replication for OCI Object Storage, you need to create a replication policy on the source bucket, specifying the destination bucket in the other region, and set the appropriate IAM permissions. This ensures that any new objects uploaded to the source bucket are automatically duplicated in the destination region for disaster recovery. Refer to Oracle documentation on Object Storage replication for detailed steps and best practices.
- A. Incorrect.
Incorrect. Load balancer settings do not handle bucket-to-bucket replication for Object Storage logs. Load balancers distribute incoming traffic or health checks for applications but are not involved in cross-region replication of Object Storage data.
- B. Correct.
Correct. You must set up a replication policy on your source bucket ('prod-logs-bucket') to specify the destination bucket ('dr-logs-bucket') in the target region (Ashburn). Additionally, you need an IAM policy allowing Object Storage service to replicate data between these buckets. This is the official Oracle Cloud Infrastructure approach to automatically replicate new objects across regions.
- C. Incorrect.
Incorrect. The 'export to object storage' feature is typically used to offload data from other services (e.g., logging analytics or streaming) into Object Storage. It does not provide automated ongoing replication from one bucket to another region. You would need a proper replication policy for seamless cross-region mirroring.
- D. Incorrect.
Incorrect. Pre-authenticated requests allow external entities to access objects in a bucket without credentials, but they do not establish an ongoing replication pipeline. Scheduling a daily job is a manual process that does not provide true near-real-time replication.
