1Z0-1123-25 Question 42
Select 3An organization is planning to rehost its on-premises environment with minimal downtime on Oracle Cloud Infrastructure (OCI) using the Oracle Cloud Migrations service. Which three fundamental actions must they perform from the Oracle Cloud Migrations console to configure and run this migration process successfully?
- A
Define the source environment in Oracle Cloud Migrations by providing on-premises system details and establishing connectivity with OCI.
- B
Create a migration plan that enumerates workloads and uses Oracle Cloud Migrations to automatically provision the necessary target resources in OCI.
- C
Configure point-in-time data uploads to an external repository for offline seeding before launching the Oracle Cloud Migrations job.
- D
Schedule replication jobs to synchronize changes from on-premises to OCI, enabling a cutover with minimal downtime.
- E
Delete the on-premises machines immediately after configuring the migration plan to avoid potential hostname conflicts.
Show answer and explanation
Correct answers: A, B, D
Explanation
In Oracle Cloud Migrations, you start by defining the source environment (on-premises servers, network details, etc.) and establishing connectivity to OCI. You then create a migration plan that outlines workloads and dependencies, leveraging Oracle Cloud Migrations to provision the necessary target resources. Finally, you set up replication schedules to keep on-premises and OCI environments in sync. These steps collectively minimize downtime and streamline the entire migration process. For more details, refer to Oracle's official documentation on the Oracle Cloud Migrations service and recommended migration best practices.
- A. Correct.
Correct. Specifying details of the on-premises systems (e.g., IP addresses, OS versions, disk layouts) and setting up a secure connection (via VPN or FastConnect) are foundational steps in Oracle Cloud Migrations. Without defining the source environment, the migration cannot proceed.
- B. Correct.
Correct. One of the key fundamentals of Oracle Cloud Migrations is creating a migration plan that captures workload details and automates provisioning of the required OCI resources. This approach streamlines planning and reduces manual configuration errors.
- C. Incorrect.
Incorrect. While some applications can benefit from additional data-seeding strategies, point-in-time offline uploads to an external repository are not a core feature of Oracle Cloud Migrations. The service is designed to handle replication and orchestration automatically once the environment is configured.
- D. Correct.
Correct. Scheduling replication ensures that changes on the on-premises environment are continuously synchronized to OCI. This capability is crucial for minimizing downtime during the final cutover, as the most recent data is already staged in the cloud.
- E. Incorrect.
Incorrect. Immediately deleting on-premises machines is not a recommended practice. You need a stable source environment to perform final replication and testing before cutting over to OCI. Premature deletion could lead to unexpected data loss or disruption.
