1Z0-1123-25 Question 124
Single answerYou work for a financial services company that needs to replicate a 5 TB file system from the Phoenix region to the Ashburn region for disaster recovery. The replication needs to be automatically updated with minimal manual intervention so that Phoenix and Ashburn remain closely synchronized. Which approach should you implement in OCI to meet these requirements?
- A
Use a Compute instance to regularly run rsync commands from the Phoenix file system to a newly created file system in Ashburn.
- B
Enable File System Replication through the OCI Console by selecting the Phoenix file system as the source and creating a replication target in Ashburn.
- C
Schedule export and import operations of block volume backups from Phoenix to Ashburn whenever the data changes on the Phoenix file system.
- D
Select synchronous replication for the file system in the Phoenix region to mirror data in real time at the block level.
Show answer and explanation
Correct answer: B
Explanation
To achieve automated, near-real-time updates with minimal human intervention, you should use OCI File System Replication. It seamlessly copies data from a source file system in the Phoenix region to a target file system in the Ashburn region and keeps them in sync. Refer to OCI File Storage documentation for detailed steps on configuring and managing File System Replication.
- A. Incorrect.
Incorrect: While rsync can copy data, it requires manual setup and scheduling, leading to higher operational overhead and potential data inconsistencies if not properly timed. It also does not leverage OCI's built-in replication capabilities.
- B. Correct.
Correct: OCI File System Replication provides an automated, asynchronous replication mechanism. You specify the source file system in Phoenix and designate Ashburn as the target region, ensuring near-real-time updates with minimal manual effort.
- C. Incorrect.
Incorrect: Exporting and importing block volume backups is time-consuming, not well-suited for continuous replication, and relies on manual tasks. This approach lacks the near-real-time sync required for disaster recovery.
- D. Incorrect.
Incorrect: OCI File Storage currently provides asynchronous replication, not synchronous block-level mirroring. There is no 'synchronous replication' checkbox for OCI File Storage that guarantees real-time lockstep data across regions.
