1Z0-1123-25 Question 47
Select 2A global financial services firm is planning a migration of hundreds of on-premises virtual machines and databases to Oracle Cloud Infrastructure (OCI). The environment includes a variety of Linux and Windows servers running custom applications with complex interdependencies. As the OCI Migration Architect, which TWO tasks should you prioritize during the discovery and inventory phase to ensure a comprehensive understanding of the workload and dependencies?
- A
Use an automated agent-based discovery tool to collect operating system versions, installed software, and resource utilization metrics from each server.
- B
Retrieve a list of publicly visible IP addresses and assume these represent the full inventory of business-critical hosts.
- C
Conduct interviews with each application team to capture dependency details, operational schedules, and compliance requirements.
- D
Immediately create a generic server baseline without detailing existing resource usage to maintain high-level planning efficiency.
- E
Migrate all production databases first and gather resource details later from logs and metrics.
Show answer and explanation
Correct answers: A, C
Explanation
During the discovery and inventory phase, combining automated methods (e.g., agent-based or network-based discovery solutions) with direct stakeholder engagement is a proven best practice. Automated tools provide objective data (operating system details, resource metrics, installed software), while interviews capture application-specific nuances, peak demand cycles, and compliance considerations that may not be evident from scans alone. Refer to Oracle� official migration documentation and best practices (such as the �OCI Migration Guide� and relevant white papers) for detailed recommendations on performing holistic discovery and planning prior to any data or application moves.
- A. Correct.
Correct. Automated tools help you gather accurate and detailed information about servers (e.g., hardware specs, OS versions, running services). This data is critical for identifying resource requirements, optimizing allocation, and planning dependency mappings.
- B. Incorrect.
Incorrect. Relying on publicly visible IPs alone is insufficient. Internal hosts or services not exposed publicly are often crucial to business functions. Omitting them leads to incomplete discovery and higher migration risks.
- C. Correct.
Correct. In addition to automated scans, direct communication with application teams reveals hidden dependencies, operational constraints, and compliance details. This qualitative data often is not fully captured by discovery tools.
- D. Incorrect.
Incorrect. A generic baseline without analyzing existing resource usage and capacity can lead to inaccurate sizing in OCI. Comprehensive resource usage profiles are vital for correct cloud resource allocation.
- E. Incorrect.
Incorrect. Migrating first and assessing later introduces significant risk. Proper discovery and inventory must precede migration activities to avoid unexpected outages, performance issues, and compliance violations.
