Read the first 7 Troubleshooting & Problem Resolution flashcards as text
Two dashboards show different totals for the same KPI because one applies a filter excluding returns. What is the best long-term fix?
Answer: Define the KPI centrally in a governed semantic layer or metrics store
A governed semantic layer ensures one certified calculation is reused across all reports.
Which escalation practice is most appropriate when a data issue exceeds a steward's authority to resolve?
Answer: Escalate to the data governance council per a defined escalation path
A defined escalation path routes cross-domain issues to the governance body with decision authority.
A data migration finished, but row counts match while financial totals differ. What should the team perform?
Answer: Field-level reconciliation such as checksums and aggregate comparisons
Matching row counts alone can hide value-level errors, so aggregate and checksum reconciliation is required.
Which situation best calls for a temporary workaround before a permanent fix?
Answer: A critical business process is blocked while root cause analysis continues
Workarounds restore business continuity for critical processes while permanent remediation is developed.
A data catalog adoption effort is failing because users find metadata outdated. What is the most effective remedy?
Answer: Assign stewards accountable for metadata currency and automate metadata harvesting
Ownership plus automated harvesting keeps metadata fresh, which drives adoption.
Which statement about root cause analysis (RCA) for data issues is most accurate?
Answer: RCA should seek systemic causes in process, people, and technology
Effective RCA examines systemic factors across process, people, and technology, not just the data fix.
A vendor-supplied dataset repeatedly arrives late, delaying executive reports. What is the CDO's best course of action?
Answer: Enforce service level agreements with the vendor and add freshness monitoring
SLAs create accountability and freshness monitoring gives early warning when deliveries slip.
