1Z0-1123-25 Question 68
Select 3You have been tasked with planning a cloud migration for a financial services company that runs over 200 virtual machines, several physical database servers, and a small fleet of custom applications in their on-premises data center. As part of the initial planning phase, you must perform source discovery to fully understand the infrastructure resources before moving them to Oracle Cloud Infrastructure. Which THREE actions are appropriate for gathering accurate and complete information about the on-premises environment?
- A
- Use an automated discovery tool to scan and inventory servers, storage, and network configurations, capturing pertinent hardware and software details in a central repository.
- B
- Interview application owners and infrastructure teams to uncover hidden dependencies and verify data from automated tools.
- C
- Rely exclusively on the organization's existing asset repository without validating entries for configuration drift or changes.
- D
- Analyze historical performance metrics from at least the past three months to identify peak usage patterns and resource requirements.
- E
- Perform a cloud migration proof-of-concept immediately with a single production-critical database to speed up discovery efforts.
Show answer and explanation
Correct answers: A, B, D
Explanation
Effective source discovery involves collecting data through automated scans, validating that data against stakeholder knowledge, and analyzing performance trends over time. Combining these methods provides a comprehensive view of existing resources, enabling a more accurate and risk-mitigated migration plan. Refer to official Oracle Cloud Infrastructure documentation for recommended discovery tools and best practices prior to migrating workloads.
- A. Correct.
Option 1: CORRECT. Automated discovery tools help collect and centralize information (e.g., OS versions, installed applications, resource usage) for each system. Used in conjunction with other methods, this ensures accurate data that migration plans can rely on.
- B. Correct.
Option 2: CORRECT. Speaking directly with application owners and platform teams provides context that automated scans can miss, such as undocumented dependencies or custom integration points.
- C. Incorrect.
Option 3: INCORRECT. Solely relying on an outdated or unverified asset repository is risky. Infrastructure may have changed without being recorded, leading to gaps in discovery.
- D. Correct.
Option 4: CORRECT. Reviewing historical performance metrics helps identify peak and average loads, sizing requirements, and usage trends, which inform target resource planning in OCI.
- E. Incorrect.
Option 5: INCORRECT. Performing an immediate POC on a mission-critical production database without prior discovery can be disruptive and dangerous. Proper discovery should precede or complement any proof-of-concept to reduce risk.
