1Z0-1123-25 Question 56
Select 2Your company is migrating a critical, customized Oracle Linux 7 AWS EC2 instance to Oracle Cloud Infrastructure (OCI). The EC2 instance includes EBS volumes for persistent data, ephemeral instance store volumes, and an attached IAM role for S3 access. You have limited downtime and want to ensure the instance retains its current OS configurations. Which two steps should you take to achieve a successful migration to OCI?
- A
Create a snapshot of the EBS volumes, export the snapshot to S3 as an OVA file, upload it to OCI Object Storage, and import it as a custom image.
- B
Exclude the ephemeral instance store volumes from the export process, as they are not supported in the OVA import workflow.
- C
Automatically replicate the IAM role in OCI by migrating the associated AWS identity and access policies.
- D
Leverage Oracle Database Migration service to clone the EC2 instance into a new OCI Compute instance.
Show answer and explanation
Correct answers: A, B
Explanation
When migrating AWS EC2 instances to OCI, you typically export the instance as an OVA (or a compatible format) from AWS, then upload the file to Object Storage in OCI to import it as a custom image. EBS volumes are exported, but ephemeral instance store volumes are not. You should also recreate any necessary identities or roles in OCI through appropriate IAM policies, as AWS IAM roles do not directly translate to OCI. Refer to Oracle documentation on importing custom images for detailed instructions and best practices.
- A. Correct.
Correct: Exporting the EBS snapshot to an OVA file and uploading it to OCI is a valid approach. OCI supports importing custom images from OVA (or VMDK/VHD) stored in OCI Object Storage.
- B. Correct.
Correct: Ephemeral instance store volumes (AWS instance store) cannot be migrated via the same process and should be excluded. Only the EBS-based volumes are included when creating the snapshot or exporting the AMI.
- C. Incorrect.
Incorrect: AWS IAM roles cannot be directly replicated in OCI. You need to create equivalent IAM policies in OCI to match the permissions requirements; it is not a straightforward automated process.
- D. Incorrect.
Incorrect: Oracle Database Migration is for databases (e.g., migrating Oracle Databases) rather than migrating entire AWS EC2 instances. It does not replicate operating system configurations or file systems of a compute instance.
