1Z0-1072-25 Question 273
Single answerYour development team needs a new test environment that mirrors the data from your production file system hosted on Oracle Cloud Infrastructure File Storage. They want the new environment up and running quickly with minimal downtime for production. Which approach should you take to achieve a complete copy of your production file system without impacting current users?
- A
Create a snapshot of the production file system, then create a new file system from that snapshot and mount it to your test environment.
- B
Temporarily unmount and detach the production file system, duplicate it to a test compartment, and reattach it to both environments.
- C
Use an operating system-level copy (e.g., rsync) to copy files from the production file system to the test environment, bypassing snapshots.
- D
Mount the snapshot directly on a second compute instance and enable read-write access to create the test environment.
Show answer and explanation
Correct answer: A
Explanation
When working with Oracle Cloud Infrastructure File Storage, snapshots are read-only, point-in-time copies of your file system. The recommended approach to cloning data for test or development purposes is to first create a snapshot and then create a new file system from that snapshot. This method provides a consistent copy of the data without interrupting normal production operations. Refer to Oracle's File Storage documentation for further details on file system snapshots, cloning procedures, and mounting best practices.
- A. Correct.
Option 1 is correct. In OCI File Storage, you can create a snapshot of your production file system (which does not cause downtime), then create a new file system based on that snapshot. This cloned file system provides a point-in-time copy of data for your test environment, without disrupting production.
- B. Incorrect.
Option 2 is incorrect because you do not need to unmount or detach the original file system to create a snapshot or a cloned file system. Doing so would cause unnecessary downtime.
- C. Incorrect.
Option 3 is incorrect because using an OS-level copying method can be time-consuming and may not guarantee a consistent point-in-time copy if files are changing during the process. OCI File Storage snapshots handle this more efficiently and without disrupting users.
- D. Incorrect.
Option 4 is incorrect because snapshots in OCI File Storage are read-only and cannot be mounted directly as read-write. You must first create a new file system from the snapshot before mounting it and writing data.
