1Z0-1123-25 Question 44
Single answerA large retail company plans to migrate 200 on-premises servers (including Oracle Databases, in-house applications, and third-party systems) to Oracle Cloud Infrastructure (OCI). Senior leadership wants a discovery, inventory, and assessment strategy that ensures minimal disruption, identifies software license requirements, and maps application dependencies. As the OCI 2025 Migration Architect, which approach should you recommend to meet these objectives effectively?
- A
A. Start migrating the most important workloads first to OCI and address additional dependencies as they surface during the migration.
- B
B. Use an automated discovery tool combined with management agents on each on-premises server to collect resource information, dependencies, and software inventory, then analyze the data for a phased migration plan.
- C
C. Conduct multiple stakeholder meetings to compile manual inventories in spreadsheets and rely solely on user input to discover application dependencies.
- D
D. Offload the entire discovery and planning process to an external consultant without providing any internal technical documentation or resources.
Show answer and explanation
Correct answer: B
Explanation
According to Oracle� recommended migration practices, discovery and inventory should be automated whenever possible to ensure accuracy and completeness. Using agent-based tools and scans allows deeper insight into resource configurations, software license needs, and application dependencies, which ultimately informs a phased, risk-mitigated migration plan. Refer to official OCI migration documentation and best practices for guidance on selecting and implementing discovery tools and management agents.
- A. Incorrect.
Option A is incorrect. Although migrating critical workloads first seems logical, skipping structured discovery can cause you to miss unknown dependencies, leading to potential downtime and rework.
- B. Correct.
Option B is correct. Leveraging automated discovery tools with management agents is a best practice for obtaining comprehensive inventory data, mapping dependencies, and planning migrations in a phased manner. This approach reduces manual errors and identifies critical application interdependencies early.
- C. Incorrect.
Option C is incorrect. While stakeholder meetings and spreadsheets can be helpful, relying solely on manual input makes it easy to miss technical details, especially in large-scale environments. It also lacks the thoroughness of automated discovery.
- D. Incorrect.
Option D is incorrect. Outsourcing the entire process without internal collaboration increases the risk of misalignment with business requirements, missed application insights, and a disconnect from critical in-house knowledge needed for accurate migration planning.
