Exam 1z0-1072-23 topic 1 question 2 discussion

Actual exam question from Oracle's 1z0-1072-23
Question #: 2
Topic #: 1
[All 1z0-1072-23 Questions]

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?

  • 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.

Selected Answer: B
QCOW2 is emulated mode which has lower performance than native mode. VMDK can be imported in a native mode.

I agree with D. 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. The supported images are VMDK and QCOW2 but Native mode is for Oracle native images, since it was mentioned in the question that it is not Oracle image then it should be emulated mode.

Selected Answer: B
Option D specifies the QCOW2 image format. QCOW2 is a virtual disk image format that is supported by OCI. However, if you select emulated mode when importing a QCOW2 image, the virtual machine will not be able to interact directly with the OCI hardware, which can result in performance degradation.
