1Z0-1123-25 Question 36
Select 2You are leading the migration of a mission-critical Linux-based workload from an on-premises data center to Oracle Cloud Infrastructure (OCI). The workload consists of multiple VMs that must be replicated with minimal downtime. You decide to leverage Oracle Cloud Migrations Service. Which two steps should you include in your plan to achieve continuous replication and a test migration before final cutover?
- A
Deploy the Oracle Cloud Migrations replication agents on each on-premises server and configure continuous replication to OCI.
- B
Perform a manual export of each VM as an OVA file and then upload these images to OCI Object Storage.
- C
Create a replication job that applies incremental changes to a replica instance on OCI and perform a test migration before final cutover.
- D
Use Oracle Cloud Migrations Service to automatically convert your on-premises VMs to Docker containers for direct deployment on Container Engine for Kubernetes.
- E
Manually shut down all on-premises VMs and then deploy fresh Compute instances in OCI using the same operating system images.
Show answer and explanation
Correct answers: A, C
Explanation
Oracle Cloud Migrations Service facilitates real-time or incremental replication of on-premises VMs to OCI, minimizing downtime and providing a way to validate workloads in the target environment before final cutover. You install agents on source servers to continuously capture changes and configure a replication job that keeps the replica updated. A test migration verifies everything runs properly in OCI, reducing risk. For more information, refer to Oracle� official documentation on Oracle Cloud Migrations workflow and best practices.
- A. Correct.
Correct. Deploying replication agents on each source server is a key requirement for the Oracle Cloud Migrations Service to capture real-time or incremental changes and replicate them to OCI.
- B. Incorrect.
Incorrect. Manually exporting each VM as OVA files and uploading to OCI Object Storage is not the recommended approach when using Oracle Cloud Migrations Service for continuous replication. This manual method doesn't leverage live or incremental replication capabilities.
- C. Correct.
Correct. Creating a replication job that applies incremental changes allows you to keep the OCI environment in sync and run a test migration before the final cutover, ensuring minimal downtime and verifying functionality.
- D. Incorrect.
Incorrect. Oracle Cloud Migrations Service does not automatically convert VMs to container images. This option is not supported for VM-to-container conversions and is not part of the standard migration workflow.
- E. Incorrect.
Incorrect. Shutting down all VMs and manually re-deploying them in OCI negates the benefit of continuous replication. This approach would introduce extended downtime and is not how you would use Oracle Cloud Migrations Service for minimal disruption.
