CDS Monitoring & Reporting Tools 2 — Questions and Answers
Question 1: Which metric is most critical when monitoring data pipeline latency in a real-time reporting environment?
- End-to-end processing time from ingestion to availability (Correct answer)
- Number of records processed per batch
- Total storage consumed by the pipeline
- Count of distinct data sources feeding the pipeline
Correct answer: End-to-end processing time from ingestion to availability
End-to-end latency directly measures how quickly data becomes available for decision-making in real-time environments.
Question 2: A data steward notices a dashboard KPI shows different values depending on the time zone of the viewer. What is the root cause to investigate first?
- Server hardware clock drift
- Lack of time zone normalization in timestamp fields (Correct answer)
- Incorrect aggregation function in the report
- Missing index on the date dimension table
Correct answer: Lack of time zone normalization in timestamp fields
Time zone normalization ensures timestamps are consistently interpreted regardless of the viewer's locale.
Question 3: Which approach best supports data lineage visibility within a reporting tool?
- Enabling query caching for faster dashboard loads
- Tagging reports with source dataset metadata and transformation steps (Correct answer)
- Restricting report editing to senior analysts only
- Archiving unused reports quarterly
Correct answer: Tagging reports with source dataset metadata and transformation steps
Tagging reports with source and transformation metadata allows stakeholders to trace where reported values originate.
Question 4: What distinguishes an operational report from an analytical report in data stewardship practice?
- Operational reports use predictive models; analytical reports use historical data
- Operational reports reflect current state for day-to-day decisions; analytical reports support trend analysis (Correct answer)
- Operational reports are generated manually; analytical reports are automated
- Operational reports require more storage than analytical reports
Correct answer: Operational reports reflect current state for day-to-day decisions; analytical reports support trend analysis
Operational reports support immediate business operations, while analytical reports are used for longer-term insight and trend evaluation.
Question 5: A monitoring alert fires every hour but no data quality issue is ever found. What should the data steward adjust?
- Increase the alert frequency to every 30 minutes
- Recalibrate the alert threshold to reduce false positives (Correct answer)
- Disable all monitoring alerts for that data asset
- Replace the monitoring tool with a new vendor solution
Correct answer: Recalibrate the alert threshold to reduce false positives
Recalibrating thresholds reduces alert fatigue caused by false positives while keeping genuine issues detectable.
Question 6: Which type of monitoring checks whether data values fall within expected statistical ranges?
- Schema monitoring
- Referential integrity monitoring
- Anomaly or outlier detection monitoring (Correct answer)
- Audit log monitoring
Correct answer: Anomaly or outlier detection monitoring
Anomaly detection monitoring flags values that deviate significantly from historical norms or predefined statistical boundaries.
Question 7: A report is certified as 'trusted' in a data catalog. What governance action must the data steward perform to maintain this certification?
- Lock the report so no further edits are allowed
- Periodically review and re-validate the report's accuracy and source alignment (Correct answer)
- Migrate the report to a separate certified environment
- Restrict catalog access to only certified consumers
Correct answer: Periodically review and re-validate the report's accuracy and source alignment
Trusted certifications require ongoing validation to ensure the report remains accurate as underlying data or logic changes.
