✍️ Sample CDS Questions & Answers
1. Which metric is most useful for measuring the effectiveness of a data lifecycle management program?
Tracking policy coverage across data assets measures how consistently the lifecycle program governs data from creation to disposal.
2. How does poor data quality affect business intelligence?
Poor data quality significantly undermines the effectiveness of business intelligence (BI) initiatives. When data is inaccurate, incomplete, or inconsistent, any analytics performed on it will yield flawed insights and reports. This directly leads to poor, misinformed business decisions, potentially causing financial losses, missed opportunities, and operational inefficiencies.
3. What is the primary purpose of system monitoring?
System monitoring enables proactive issue detection and health maintenance, reducing downtime and ensuring consistent service delivery.
4. What is the purpose of a staging environment?
Staging environments replicate production conditions for testing configurations and changes, reducing the risk of deployment failures affecting live systems.
5. What is the purpose of data lineage tracking?
Data lineage tracking traces data from origin through all transformations and movements, supporting audit requirements, troubleshooting, and impact analysis.
6. Which activity is part of the 'data creation' stage in a typical data lifecycle model?
Entry validation at the creation stage ensures data meets quality and format standards before it enters downstream systems.
