1Z0-1123-25 Question 126
Single answerYour organization hosts a critical application on Oracle Cloud Infrastructure (OCI) File Storage in the Phoenix region. To meet disaster recovery (DR) requirements, you need to replicate this file system to the Ashburn region with minimal manual intervention. Which single step must you complete in the Phoenix region console to implement cross-region replication for the existing file system?
- A
Enable 'Export Snapshots' on the existing file system in Phoenix to replicate all data automatically to Ashburn.
- B
Configure a block volume backup policy on the File Storage mount to schedule regular backups at Phoenix and restore them manually in Ashburn.
- C
Create a replication resource from the source file system in Phoenix to a target file system in Ashburn using OCI File System Replication.
- D
Modify the mount target in Ashburn so that it directly accesses the file system in Phoenix for seamless failover.
Show answer and explanation
Correct answer: C
Explanation
OCI File System Replication is designed to automatically synchronize data changes from the source region to the DR region. By configuring replication at the source file system in Phoenix and targeting a new or existing file system in Ashburn, you ensure near real-time, automated data replication. For more guidance, refer to OCI File Storage documentation on replicating file systems across regions.
- A. Incorrect.
Option 1 is incorrect. 'Export Snapshots' alone does not create continuous, automated cross-region replication; it only allows snapshot creation for local or manual transfer use.
- B. Incorrect.
Option 2 is incorrect. Block volume backup policies do not cover File Storage data replication. This approach would also be manual and less efficient than native File System Replication.
- C. Correct.
Option 3 is correct. OCI File System Replication allows you to create a replication resource from the source file system in Phoenix so that all changes are automatically propagated to the Ashburn region.
- D. Incorrect.
Option 4 is incorrect. Simply modifying the mount target in Ashburn to point to the Phoenix file system does not replicate data; it would still rely on Phoenix availability and does not establish a DR copy in Ashburn.
