1Z0-1123-25 Question 71
Select 2You have been tasked with migrating a diverse on-premises environment to Oracle Cloud Infrastructure (OCI). The environment includes Linux and Windows servers running various applications, databases, and file services. As part of the initial planning phase, you must perform a thorough source discovery to understand the current infrastructure resources and dependencies. Which two approaches should you follow to ensure an accurate and comprehensive discovery?
- A
Use a combination of automated discovery tools and architecture diagrams to identify servers, storage devices, and their configurations.
- B
Assess resource usage patterns in your environment, including CPU, memory, storage, and network utilization.
- C
Limit discovery activities to only business-critical servers to reduce complexity and overhead.
- D
Rely solely on user interviews to collect information about the on-premises environment.
Show answer and explanation
Correct answers: A, B
Explanation
Effective source discovery combines automated tools, stakeholder input, and existing documentation to build an accurate resource inventory. This helps identify potential migration challenges, ensure all dependencies are captured, and optimize the architecture on OCI. Refer to Oracle's migration planning documentation for best practices in orchestrating a thorough, efficient assessment of on-premises environments.
- A. Correct.
This is a correct approach. Automated tools help gather detailed resource data (OS versions, installed applications, storage allocations, etc.) while architecture diagrams ensure you validate and cross-check discovered information, avoiding gaps in your inventory.
- B. Correct.
This is correct. Understanding resource utilization patterns is essential for right-sizing in OCI. By tracking CPU, memory, storage, and network usage, you create a more accurate resource map for migration planning.
- C. Incorrect.
This is incorrect. Limiting discovery only to business-critical servers risks overlooking dependencies on seemingly less important services. Comprehensive discovery is crucial to avoid unexpected breakages post-migration.
- D. Incorrect.
This is incorrect. Although user interviews can provide valuable context, relying solely on them can lead to incomplete data, undocumented services, or overlooked dependencies. Combining interviews with automated discovery provides the most reliable results.
