1Z0-1072-25 Question 28
Single answerYour organization has a heavily customized Linux-based Compute instance running in the us-ashburn-1 region on Oracle Cloud Infrastructure (OCI). You now need to make an identical image of this instance available in the uk-london-1 region for disaster recovery. Which method provides an efficient way to replicate your custom image across regions?
- A
Use the built-in Copy Image functionality to replicate the custom image directly from us-ashburn-1 to uk-london-1.
- B
Export the instance� boot volume to an on-premises data center first, then import it into the uk-london-1 region.
- C
Rely on automatic cross-region replication of boot volume snapshots to make the image immediately available in uk-london-1.
- D
Manually recreate the image in uk-london-1 by installing all custom software on a base Oracle-provided image.
Show answer and explanation
Correct answer: A
Explanation
Copying a custom image between regions in OCI is typically done using the Copy Image functionality provided in the Console or through the OCI CLI. This approach is recommended for ensuring consistency and efficiency when replicating images for tasks such as disaster recovery or deploying standardized environments. Refer to Oracle documentation on 'Managing Compute Images' for step-by-step guidance on copying images across regions.
- A. Correct.
Correct. Using Copy Image in the OCI Console or CLI is the most direct method. This built-in feature automates replication of your custom image from one region to another without needing an intermediary export/import process.
- B. Incorrect.
Incorrect. While boot volumes can be exported, sending them back on-premises adds unnecessary complexity and delay. OCI offers a native Copy Image feature specifically designed for cross-region image replication.
- C. Incorrect.
Incorrect. Boot volume snapshots are region-specific unless explicitly configured for cross-region replication, and even then you would have to create a custom image from the snapshot manually. It's not automatically available as a complete image in another region without further steps.
- D. Incorrect.
Incorrect. Manually reinstalling software on an Oracle-provided base image is possible but time-consuming and prone to configuration errors. The Copy Image feature avoids these issues by replicating your custom image exactly.
