1Z0-1072-25 Question 208
Single answerYour organization runs a critical application with data stored across three Block Volumes in a single Availability Domain (AD). These volumes are grouped into a Volume Group to manage them consistently. You have a short 30-minute maintenance window to create a read/write test environment with an exact copy of the production data (point-in-time consistency) and minimal disruption to the application. Which approach should you use?
- A
Create a full backup of the Volume Group and restore it to new Block Volumes in the same AD.
- B
Clone the Volume Group in the same AD and attach the cloned volumes to the test environment.
- C
Detach each Block Volume individually and create separate volume backups before re-attaching to the test environment.
- D
Export the data to an Object Storage bucket and then import it into new Block Volumes for testing.
Show answer and explanation
Correct answer: B
Explanation
When you need a quick, point-in-time, and writable copy of multiple Block Volumes managed as a group, creating a Volume Group clone in Oracle Cloud Infrastructure is the recommended approach. Cloning is near-instant and preserves consistency across all volumes in the group, making it ideal for short maintenance windows and test environment setups. Refer to Oracle Cloud Infrastructure documentation on 'Cloning a Volume Group' for best practices and detailed instructions.
- A. Incorrect.
Option 1: Although creating a full Volume Group backup and restoring it is possible, it is more time-consuming and typically used for disaster recovery. Restoring from a backup may exceed the short maintenance window, so it� not the best approach for a quick read/write environment.
- B. Correct.
Option 2: Cloning the Volume Group in the same AD is the most efficient solution. A clone is created almost instantly and is immediately available for read/write. This approach meets the requirement of minimal downtime and provides a point-in-time copy consistent across all volumes in the group.
- C. Incorrect.
Option 3: Detaching each Block Volume and creating individual backups is cumbersome and can disrupt the application more than necessary. This also risks inconsistency if the volumes aren�t snapped at exactly the same point in time.
- D. Incorrect.
Option 4: Exporting data to Object Storage and re-importing into new volumes is valid for certain migrations or long-term storage, but it� time-intensive. It doesn�t meet the requirement for minimal downtime within a 30-minute window.
