Oracle Cloud Infrastructure 2022 Architect Associate — Question 14

You are in the process of migrating several legacy applications from on-premises to Oracle Cloud Infrastructure (OCI). The current servers are already virtualized. However, you notice that the version of CentOS currently running does not align with any of the Oracle-provided compute images.
How would you migrate your existing virtual server images to OCI?

Answer options

• A. Export your current image in the VDI format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.
• B. Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers.
• C. Export your current image in the QED format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers.
• D. Export your current image in the VMDK format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.

Correct answer: D

Explanation

The correct answer is D, as exporting the image in VMDK format and selecting native mode ensures the best performance in OCI. Options A, B, and C are incorrect because they use formats or modes that are not optimal for performance or compatibility with OCI's architecture.
