1Z0-1072-25 Question 271
Single answerYou manage a production application that uses Oracle Cloud Infrastructure (OCI) File Storage to store critical shared data for multiple compute instances. Your team needs to spin up a test environment with the latest production data for QA purposes, but you want to minimize overhead on the production file system. Which action should you take to quickly provide an up-to-date copy of the production data for the new environment?
- A
Create a snapshot of the production file system, then create a new file system by cloning the snapshot for the test environment.
- B
Export the production file system as an NFS share to a temporary bucket in Oracle Object Storage, then restore from that bucket to a new file system.
- C
Enable cross-region data replication on the production file system to synchronize its contents, then attach the replicated file system for use in the test environment.
- D
Mount a read/write replica of the same production file system from another Availability Domain to simulate a fresh test environment.
Show answer and explanation
Correct answer: A
Explanation
To create an isolated test environment with the most recent data while minimizing impact on the production system, the best practice is to take a snapshot of the production file system and then clone that snapshot to form a new file system. You can then mount this cloned file system in your test environment. This approach is highly efficient, reduces downtime, and avoids the potential data corruption or performance issues that arise from directly using production data. For more details, refer to Oracle Cloud Infrastructure File Storage documentation regarding snapshots and clones.
- A. Correct.
Option 1 is correct. Creating a snapshot of the existing file system, then cloning that snapshot to form a new file system is the recommended method for quickly providing an up-to-date and isolated copy of your production data. This process has minimal performance impact on the primary (production) file system and is straightforward to set up.
- B. Incorrect.
Option 2 is incorrect. While you can transfer data to Object Storage, this process is cumbersome and not the recommended approach for creating a live, mountable test environment. File Storage snapshots remain managed within the File Storage service, making the direct snapshot-to-clone workflow simpler and more efficient.
- C. Incorrect.
Option 3 is incorrect. Cross-region replication of a file system in OCI is designed for disaster recovery and geo-redundancy rather than creating near-instant copies for testing. This method can introduce additional costs and complexity if the only goal is to have a local test environment quickly.
- D. Incorrect.
Option 4 is incorrect. Mounting a read/write replica in another Availability Domain without using a snapshot or clone does not provide an isolated test environment. This approach risks data conflicts and doesn�t create a dedicated copy to work on.
