1Z0-1123-25 Question 72
Select 2Your organization is planning to migrate several critical applications from an on-premises data center to Oracle Cloud Infrastructure (OCI). You have been tasked with performing a thorough source discovery to identify all servers, applications, and dependencies in the on-premises environment, ensuring nothing is overlooked. Which two actions should you take to achieve a comprehensive resource inventory before proceeding with the migration?
- A
Use Oracle Enterprise Manager to gather detailed information about on-premises databases and supplement this with OS-level scans to capture CPU, memory, and storage utilization.
- B
Rely solely on network load balancer logs to list all servers communicating through the data center perimeter.
- C
Conduct stakeholder interviews with application owners to uncover dependencies, usage patterns, and any undocumented resources.
- D
Perform the migration immediately and document any missing servers only after the workloads have been deployed in OCI.
Show answer and explanation
Correct answers: A, C
Explanation
Oracle recommends a multi-faceted approach to on-premises discovery that includes agent-based and agentless scans, stakeholder interviews, and existing management tools (for example, Oracle Enterprise Manager, CMDBs, or inventory management systems) for cross-verification. By combining automated discovery with application owner insights, migration architects can create an accurate and complete baseline of the current environment, which is essential for successful OCI migration. Refer to Oracle� documentation on �Planning an On-Premises to Cloud Migration� for detailed guidelines on resource discovery and best practices.
- A. Correct.
Option 1 is correct. Using Oracle Enterprise Manager to inventory databases provides in-depth details about operational characteristics, while OS-level scanning offers visibility into server configurations. Combining these methods helps ensure a comprehensive database and infrastructure inventory before migration.
- B. Incorrect.
Option 2 is incorrect. Network load balancer logs can provide some visibility into traffic patterns, but relying solely on them often misses critical systems and internal communication paths that do not traverse the perimeter load balancer.
- C. Correct.
Option 3 is correct. Talking directly to application owners uncovers hidden or undocumented details such as internal dependencies, service accounts, and resource usage spikes. This qualitative input complements automated scans to form a more complete picture of the on-premises environment.
- D. Incorrect.
Option 4 is incorrect. Migrating first and then documenting missing servers is risky and can lead to missed dependencies, increased downtime, and unplanned resource requirements. Proper resource discovery must occur before migration to reduce these pitfalls.
