1Z0-1072-25 Question 26
Single answerYour organization has created a custom Linux image with specialized security software for your web applications. You need to deploy this same custom image across multiple OCI regions to meet compliance and disaster recovery requirements. Which approach should you use to most efficiently replicate the custom image to a new region?
- A
Use the Copy Image feature in the OCI Console or CLI to replicate the custom image to the other region.
- B
Rebuild the image in the new region by starting with an Oracle-provided platform image and installing your custom software again manually.
- C
Detach the boot volume in the source region, attach it to a compute instance in the target region, and then create a custom image from that attached volume.
- D
Export the image to local storage, then upload and import it into each region as a new custom image.
Show answer and explanation
Correct answer: A
Explanation
When you need to use the same custom OS image across several OCI regions, the recommended approach is to use the built-in Copy Image function available through the Console, CLI, or API. This feature automates the replication of custom images, minimizing operational overhead and ensuring consistency. Refer to OCI Custom Images documentation for detailed steps on copying and managing compute images across regions.
- A. Correct.
Correct. OCI provides a built-in Copy Image feature that replicates a custom image directly from one region to another. This approach streamlines the process and ensures a reliable, consistent image across multiple regions.
- B. Incorrect.
Incorrect. Installing software manually in each region introduces risk of inconsistency and a time-consuming process, particularly when configuring multiple security-related components.
- C. Incorrect.
Incorrect. You cannot directly attach a boot volume from one region to a compute instance in another region. This method is neither supported nor efficient.
- D. Incorrect.
Incorrect. While exporting and importing images is technically possible, it adds unnecessary complexity compared to the simpler and more reliable Copy Image functionality.
