Oracle Cloud Infrastructure 2023 Architect Associate — Question 50

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 VMDK format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.
• 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 QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers.

Correct answer: B

Explanation

The correct answer is B because the VMDK format is supported by OCI for importing custom images, and selecting native mode optimizes performance. Options A, C, and D are incorrect as they use unsupported formats or modes that do not provide the best performance for this migration scenario.
