D) Generate data lineage diagrams Answer: B Explanation: Taskflows enable complex orchestration, allowing sequential, parallel, conditional, and looped execution of tasks. Question 19. Which metadata type is captured by the Enterprise Data Catalog to help business users understand data meaning? A) Technical column statistics B) Business Glossary terms C) Network latency metrics D) Encryption keys Answer: B Explanation: Business Glossary terms provide semantic context, making data understandable to non‑technical stakeholders. Question 20. End‑to‑End Data Lineage is essential because it: A) Improves query performance in the warehouse B) Enables impact analysis and compliance reporting by showing data flow from source to target C) Automatically encrypts data at rest

D) Reduces storage costs Answer: B Explanation: Lineage visualizes how data moves and transforms, aiding impact analysis, audit, and regulatory compliance. Question 21. Which data quality capability helps identify outliers and data distribution patterns before any transformation? A) Data Standardization B) Data Profiling C) Data Masking D) Data Archiving Answer: B Explanation: Data profiling examines data characteristics (e.g., min, max, frequency) to reveal anomalies and patterns. Question 22. In cloud data governance, the term “policy enforcement point” (PEP) refers to: A) The UI where users create policies B) The component that intercepts data access requests and enforces defined policies

B) Conversion of PowerCenter assets such as mappings and workflows to IDMC objects C) Manual testing of data pipelines D. Scheduling of batch jobs Answer: B Explanation: Migration Factory leverages AI to automatically convert existing PowerCenter objects into IDMC equivalents, reducing manual effort. Question 25. Which of the following assets typically requires manual effort after automated conversion from PowerCenter to IDMC? A) Simple ELT mappings with no complex logic B) Custom Java transformations not supported in IDMC C. Standard source‑to‑target connections D. Built‑in data quality rules Answer: B Explanation: Custom code (e.g., Java, stored procedures) may not have direct equivalents in IDMC and often need manual redesign. Question 26. The primary purpose of the Validation phase in PowerCenter migration is:
