1Z0-1123-25 Question 123
Select 2Your team needs to replicate an existing OCI File Storage file system from the Phoenix region to the Ashburn region for disaster recovery. They plan to use the native cross-region replication feature to automatically synchronize the data. Which two steps must you perform to implement the replication successfully?
- A
Create a new replication relationship from the source file system by specifying the target region and selecting either an existing or new file system as the replication target.
- B
Enable replication by creating a new replication schedule in the IAM policy set for the File Storage service.
- C
Ensure both source and target file systems are in the same compartment and the same VCN for the replication to function.
- D
Allow the File Storage service to create snapshots on the source file system as part of the native replication process.
- E
Configure a Data Flow application to periodically transfer the data from the source file system to the target region.
Show answer and explanation
Correct answers: A, D
Explanation
Oracle Cloud Infrastructure File Storage Service supports native cross-region replication. To configure it, you typically set up the replication relationship from the source file system to a specified target file system in another region. The process involves creating or designating the target file system and allowing the source File Storage service to take snapshots and replicate data increments. IAM policies ensure the appropriate permissions, but you do not schedule replication through IAM policies themselves. Refer to the official OCI File Storage documentation for step-by-step configuration details on cross-region replication.
- A. Correct.
Correct. Setting up cross-region replication involves creating or specifying a target file system in the destination region and establishing a replication relationship from the source file system. You can do this from the OCI Console or via CLI/API by choosing the target region and file system (new or existing).
- B. Incorrect.
Incorrect. You do not configure replication via IAM policies or by creating a replication schedule inside them. IAM policies control access permissions, but the replication schedule and parameters are configured directly on the source file system in the File Storage service interface or via APIs/CLI.
- C. Incorrect.
Incorrect. Although the source and target file systems need to be in the same tenancy, they do not need to reside in the same VCN or even the same compartment. Cross-region replication only requires that the File Storage service be available in both regions and that IAM policies allow the necessary operations.
- D. Correct.
Correct. Native replication uses snapshots of the source file system to replicate data to the target region. Oracle File Storage automatically manages these snapshots as part of the replication cycle, so you must allow the service to create snapshots.
- E. Incorrect.
Incorrect. OCI Data Flow is not required for native file system replication. While Data Flow could be used for custom data movement pipelines, it is not the recommended or standard approach for replicating an OCI File Storage file system.
