1Z0-1072-25 Question 27
Single answerYour company has created a custom application stack on an Oracle Linux instance in the us-phoenix-1 region. They now need to quickly replicate this environment in the eu-frankfurt-1 region to support a new project. Which method allows you to replicate the custom image across regions so you can launch new instances with minimal manual setup in eu-frankfurt-1?
- A
Export the boot volume to your local machine, then upload and recreate the instance in eu-frankfurt-1
- B
Use the Copy Image feature to replicate your custom image directly from us-phoenix-1 to eu-frankfurt-1
- C
Create a boot volume backup in us-phoenix-1 and attach it to an instance created in eu-frankfurt-1
- D
Use the standard Oracle Linux platform image in eu-frankfurt-1 and manually install all custom applications
Show answer and explanation
Correct answer: B
Explanation
OCI allows you to create and manage custom images, which include the operating system and custom software configurations. By using the Copy Image feature (available through both the Console and CLI), you can replicate these custom images to different regions without exporting volumes or manually reconfiguring each instance. Refer to OCI documentation on �Copy a Custom Image� for step-by-step guidance.
- A. Incorrect.
Option 1: Incorrect. Exporting boot volumes locally and re-uploading them is a more cumbersome process. It requires manual steps and additional configurations, making it less efficient for a straightforward image replication across regions.
- B. Correct.
Option 2: Correct. Oracle Cloud Infrastructure provides a Copy Image feature that lets you replicate a custom image directly to another region through the console or CLI. This streamlines deploying identical instances in multiple regions with minimal manual overhead.
- C. Incorrect.
Option 3: Incorrect. While you can back up and restore boot volumes, attaching a boot volume backup from one region to another is not as direct or streamlined as using the built-in image copy function. It's also more prone to configuration errors and extra manual steps.
- D. Incorrect.
Option 4: Incorrect. Using a standard Oracle Linux platform image in the target region would require you to install and configure all custom software again, which defeats the purpose of quickly replicating a fully configured custom image.
