1Z0-1123-25 Question 45
Select 3You are leading the migration planning for a healthcare company that needs to move hundreds of on-premises Windows and Linux servers hosting multiple mission-critical applications to Oracle Cloud Infrastructure (OCI). They require a thorough inventory of their environment, including dependencies, software versions, and compliance considerations, to ensure no critical details are overlooked. Which three steps should you include in your discovery and inventory process to ensure a comprehensive migration assessment?
- A
Use automated discovery tools to gather detailed OS versions, patch levels, and application software inventories.
- B
Rely entirely on business-unit spreadsheets to gather all current application and server information.
- C
Map application dependencies and network communication flows using specialized discovery or process-mapping tools.
- D
Adopt a single default VM shape and storage capacity assumption for all workloads, regardless of actual utilization.
- E
Perform a compliance gap analysis for regulated data (e.g., HIPAA constraints, PII handling) during the discovery phase.
Show answer and explanation
Correct answers: A, C, E
Explanation
In an OCI migration project, an accurate and thorough discovery and inventory process is essential. Automated discovery tools help maintain current, comprehensive details on both infrastructure and applications. Mapping application dependencies prevents missing critical communication paths, while compliance evaluations ensure regulatory requirements are met. Refer to the official Oracle Cloud Infrastructure documentation and migration best practices to learn more about recommended discovery and assessment processes.
- A. Correct.
Option 1 is correct. Using automated tools helps ensure an accurate and up-to-date inventory of servers, installed software, versions, and patches, reducing omissions and human error.
- B. Incorrect.
Option 2 is incorrect. While departmental spreadsheets can be a starting point, relying solely on them often leads to incomplete data and outdated information, missing systems or dependencies not documented by business units.
- C. Correct.
Option 3 is correct. Dependency mapping reveals crucial details about how applications communicate with each other, underlying databases, and external services, providing insight into common migration pitfalls such as network and port configurations.
- D. Incorrect.
Option 4 is incorrect. Setting a single default for VM shapes and storage leads to poor resource-sizing decisions and can cause overspending or performance degradation. Proper sizing in OCI should reflect actual workload requirements discovered through data collection.
- E. Correct.
Option 5 is correct. Conducting a compliance gap analysis is a critical part of a migration project, especially in regulated environments. This ensures that security and data protection requirements are considered from the start.
