Question 381<\/b><\/h3>\n

What is the main purpose of establishing data quality acceptance criteria before a data migration?<\/b><\/p>\n

    \n
  1. To define measurable conditions that migrated data must satisfy<\/span><\/li>\n
  2. To eliminate the need for source data profiling<\/span><\/li>\n
  3. To prevent users from accessing migrated records<\/span><\/li>\n
  4. To guarantee that no transformation will occur<\/span><\/li>\n<\/ol>\n

    Correct Answer: 1<\/b><\/p>\n

    Explanation<\/b><\/p>\n

    Data quality acceptance criteria define measurable conditions that migrated data must satisfy before the migration is considered successful. These criteria can address completeness, validity, uniqueness, consistency, referential integrity, and other business requirements. Establishing them before migration provides an objective basis for evaluating results rather than relying on assumptions after the data has been loaded. Acceptance criteria do not remove the need for profiling or transformation. Instead, they help teams determine whether the final migrated dataset is suitable for its intended business use.<\/span><\/p>\n

    Question 382<\/b><\/h3>\n

    A data source contains many duplicate customer records. Which activity should be performed before designing a duplicate-remediation solution?<\/b><\/p>\n

      \n
    1. Delete all records with similar names<\/span><\/li>\n
    2. Disable uniqueness checks<\/span><\/li>\n
    3. Analyze matching attributes and determine how duplicates are identified<\/span><\/li>\n
    4. Change the database platform<\/span><\/li>\n<\/ol>\n

      Correct Answer: 3<\/b><\/p>\n

      Explanation<\/b><\/p>\n

      Before implementing duplicate remediation, the organization should understand how duplicate records are identified. This requires analyzing relevant matching attributes such as customer identifiers, names, addresses, contact information, or other business-defined characteristics. The team should determine which combinations provide reliable evidence that two records represent the same entity. Automatically deleting similar records can remove legitimate records, while disabling uniqueness controls worsens the problem. A well-defined matching approach allows remediation to be accurate, repeatable, and aligned with business rules.<\/span><\/p>\n

      Question 383<\/b><\/h3>\n

      Which practice best supports consistent interpretation of a business-critical data element across departments?<\/b><\/p>\n

        \n
      1. Allowing each department to define the element independently<\/span><\/li>\n
      2. Maintaining an approved shared business definition<\/span><\/li>\n
      3. Removing metadata from departmental systems<\/span><\/li>\n
      4. Using different calculation methods for each report<\/span><\/li>\n<\/ol>\n

        Correct Answer: 2<\/b><\/p>\n

        Explanation<\/b><\/p>\n

        A shared and approved business definition provides a common understanding of what a critical data element means and how it should be used. This reduces semantic differences between departments and improves consistency in reporting, integrations, quality rules, and governance decisions. Independent departmental definitions can create conflicting interpretations of the same information. Supporting metadata, ownership, acceptable values, and calculation rules can further strengthen the shared definition. Centralized governance does not prevent departments from using the data; it ensures that important business concepts have consistent meaning.<\/span><\/p>\n

        Question 384<\/b><\/h3>\n

        What is the most appropriate response when a data quality issue repeatedly returns after individual records are corrected?<\/b><\/p>\n

          \n
        1. Continue correcting the same records indefinitely<\/span><\/li>\n
        2. Remove the quality rule<\/span><\/li>\n
        3. Increase the number of dashboard widgets<\/span><\/li>\n
        4. Investigate and address the underlying source or process causing the issue<\/span><\/li>\n<\/ol>\n

          Correct Answer: 4<\/b><\/p>\n

          Explanation<\/b><\/p>\n

          Repeated recurrence after individual records are corrected indicates that the underlying cause has probably not been addressed. The organization should investigate the source, process, integration, validation control, or user activity responsible for generating the problem. Correcting individual records treats symptoms but may not prevent new errors from appearing. Root-cause remediation can reduce recurring workload and improve long-term quality. The appropriate solution may involve stronger preventive controls, process changes, source corrections, or improved validation rather than repeated manual correction.<\/span><\/p>\n

          Question 385<\/b><\/h3>\n

          Which characteristic makes a data quality metric most useful for governance decisions?<\/b><\/p>\n

            \n
          1. It is clearly defined, measurable, repeatable, and connected to business impact<\/span><\/li>\n
          2. It changes calculation methods frequently<\/span><\/li>\n
          3. It measures only technical database activity<\/span><\/li>\n
          4. It is based on undocumented assumptions<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1<\/b><\/p>\n

            Explanation<\/b><\/p>\n

            A useful governance metric should have a clear definition, measurable calculation, consistent population, and meaningful connection to business objectives or risk. Repeatability allows results to be compared across time, while business relevance helps governance teams determine where action is necessary. Metrics based on undocumented assumptions or constantly changing calculations can produce misleading results. Technical measures may be useful, but they should support meaningful quality objectives rather than exist only because they are easy to collect. Well-defined metrics provide reliable evidence for governance decisions.<\/span><\/p>\n

            Question 386<\/b><\/h3>\n

            Why should data quality rules be tested against representative records before being deployed broadly?<\/b><\/p>\n

              \n
            1. To increase the size of the database<\/span><\/li>\n
            2. To determine whether the rules correctly identify expected quality conditions<\/span><\/li>\n
            3. To eliminate data ownership responsibilities<\/span><\/li>\n
            4. To prevent all exceptions from being recorded<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2<\/b><\/p>\n

              Explanation<\/b><\/p>\n

              Testing quality rules against representative records helps determine whether the logic behaves as intended across normal, invalid, boundary, and legitimate exception scenarios. Without testing, a rule may produce false positives, miss genuine problems, or behave incorrectly with unusual values. Representative testing provides evidence that the rule is suitable before it is applied broadly. It does not eliminate ownership or exception handling requirements. Proper validation of quality rules improves confidence in monitoring results and reduces unnecessary remediation caused by poorly designed controls.<\/span><\/p>\n

              Question 387<\/b><\/h3>\n

              A source system introduces a new identifier format. What should be assessed before updating downstream integrations?<\/b><\/p>\n

                \n
              1. Only the system’s storage capacity<\/span><\/li>\n
              2. The number of users accessing the source<\/span><\/li>\n
              3. The affected mappings, validation rules, relationships, and downstream dependencies<\/span><\/li>\n
              4. Only the visual appearance of reports<\/span><\/li>\n<\/ol>\n

                Correct Answer: 3<\/b><\/p>\n

                Explanation<\/b><\/p>\n

                A change to an identifier format can affect integrations, mappings, validation rules, relationships, reconciliation processes, and downstream applications. An impact assessment should identify where the existing format is consumed and determine what changes are required to maintain compatibility. This is particularly important when identifiers are used for matching, referential integrity, or reconciliation. Reviewing only storage or report appearance would overlook important dependencies. Early impact analysis reduces the risk of broken integrations, failed matching, and inconsistent records after the source system change.<\/span><\/p>\n

                Question 388<\/b><\/h3>\n

                What is the primary benefit of assigning ownership to a critical data quality rule?<\/b><\/p>\n

                  \n
                1. It identifies who is accountable for maintaining the rule and responding to relevant issues<\/span><\/li>\n
                2. It prevents the rule from ever being changed<\/span><\/li>\n
                3. It eliminates the need for governance review<\/span><\/li>\n
                4. It guarantees that the source data is accurate<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 1<\/b><\/p>\n

                  Explanation<\/b><\/p>\n

                  Assigning ownership to a critical data quality rule establishes accountability for maintaining its definition, reviewing its effectiveness, and responding when quality conditions are breached. Ownership also provides a clear escalation point when the rule requires modification or when recurring issues need attention. A rule owner does not guarantee that source data will always be accurate or prevent legitimate changes. Governance review may still be required. Clear accountability helps ensure that important controls remain relevant, maintained, and connected to business requirements.<\/span><\/p>\n

                  Question 389<\/b><\/h3>\n

                  Which condition is most likely to create an orphaned record?<\/b><\/p>\n

                    \n
                  1. A record uses an approved reference value<\/span><\/li>\n
                  2. A record contains a valid unique identifier<\/span><\/li>\n
                  3. A record is updated according to a naming standard<\/span><\/li>\n
                  4. A record references a related entity that no longer exists<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 4<\/b><\/p>\n

                    Explanation<\/b><\/p>\n

                    An orphaned record occurs when a record contains a reference to a related entity that is missing or no longer available. For example, a child record may contain a reference to a parent record that has been deleted or was never successfully migrated. Orphaned records can cause inaccurate relationships, reporting problems, and process failures. Referential integrity controls can help prevent or identify these conditions. Valid identifiers and approved values alone do not guarantee that referenced relationships remain intact.<\/span><\/p>\n

                    Question 390<\/b><\/h3>\n

                    Which approach is most appropriate for prioritizing multiple data quality issues?<\/b><\/p>\n

                      \n
                    1. Resolve issues strictly in the order they were reported<\/span><\/li>\n
                    2. Prioritize according to business impact, risk, and criticality<\/span><\/li>\n
                    3. Resolve the issues with the longest descriptions first<\/span><\/li>\n
                    4. Prioritize issues affecting the smallest datasets<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 2<\/b><\/p>\n

                      Explanation<\/b><\/p>\n

                      Data quality issues should generally be prioritized according to business impact, risk, and the criticality of affected data or processes. This approach directs limited remediation resources toward problems that could cause the greatest operational, financial, compliance, or customer consequences. The order in which issues are reported does not necessarily reflect their importance. Dataset size can provide useful context but should not be the sole prioritization factor. Risk-based prioritization helps governance teams address the most consequential quality problems first.<\/span><\/p>\n

                      Question 391<\/b><\/h3>\n

                      What is the main purpose of a data quality scorecard?<\/b><\/p>\n

                        \n
                      1. To replace all detailed quality rules<\/span><\/li>\n
                      2. To provide a concise view of quality performance against defined measures or targets<\/span><\/li>\n
                      3. To store transactional records<\/span><\/li>\n
                      4. To prevent users from modifying data<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 2<\/b><\/p>\n

                        Explanation<\/b><\/p>\n

                        A data quality scorecard provides a concise view of quality performance using defined measures, targets, and often trends or status indicators. It helps stakeholders understand whether important quality objectives are being met and where attention may be required. A scorecard does not replace detailed quality rules or function as a transactional data store. Its purpose is to communicate performance effectively and support governance decisions. Well-designed scorecards can also help compare domains, sources, or critical data elements using consistent measurement approaches.<\/span><\/p>\n

                        Question 392<\/b><\/h3>\n

                        Why is data classification useful when determining data quality controls?<\/b><\/p>\n

                          \n
                        1. It helps align controls with the importance, sensitivity, or risk associated with the data<\/span><\/li>\n
                        2. It guarantees complete data<\/span><\/li>\n
                        3. It eliminates data stewardship<\/span><\/li>\n
                        4. It prevents authorized access<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 1<\/b><\/p>\n

                          Explanation<\/b><\/p>\n

                          Data classification helps organizations understand the characteristics and risk associated with different types of information. This can guide decisions about appropriate quality controls, monitoring intensity, access requirements, retention, and governance attention. More important or sensitive data may require stronger controls and closer monitoring than lower-risk information. Classification does not guarantee completeness or eliminate stewardship responsibilities. Instead, it provides useful context for applying proportional governance and quality practices based on business value and risk.<\/span><\/p>\n

                          Question 393<\/b><\/h3>\n

                          A data quality metric improves from 92% to 98% after remediation. What should the team do next?<\/b><\/p>\n

                            \n
                          1. Immediately remove the metric<\/span><\/li>\n
                          2. Assume all related issues are permanently resolved<\/span><\/li>\n
                          3. Verify the result and continue monitoring for sustained improvement<\/span><\/li>\n
                          4. Lower the quality target to 90%<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 3<\/b><\/p>\n

                            Explanation<\/b><\/p>\n

                            An improvement from 92% to 98% is positive, but the team should verify the result and continue monitoring. Verification can confirm that the measurement population and calculation remained consistent and that the improvement reflects actual data quality changes. Continued monitoring determines whether the improvement is sustained or whether the problem returns. Removing the metric or assuming permanent resolution would reduce visibility into future performance. Quality targets should remain aligned with business requirements rather than being lowered simply because performance improved.<\/span><\/p>\n

                            Question 394<\/b><\/h3>\n

                            Which activity best supports auditability of data quality management?<\/b><\/p>\n

                              \n
                            1. Recording quality decisions, rule changes, remediation actions, and responsible parties<\/span><\/li>\n
                            2. Allowing undocumented changes to quality rules<\/span><\/li>\n
                            3. Deleting historical issue records after resolution<\/span><\/li>\n
                            4. Using informal discussions as the only evidence<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 1<\/b><\/p>\n

                              Explanation<\/b><\/p>\n

                              Auditability requires sufficient evidence to reconstruct important decisions and actions. Documenting quality rules, changes, approvals, remediation activities, responsible parties, and relevant results creates a traceable history of how quality was managed. Undocumented rule changes and deleted issue records make it difficult to determine why decisions were made or whether controls operated appropriately. Informal discussions may provide useful context but are not a reliable substitute for formal records. Strong auditability supports governance, accountability, compliance, and investigation of historical quality events.<\/span><\/p>\n

                              Question 395<\/b><\/h3>\n

                              What should be considered when defining the population used to calculate a data quality metric?<\/b><\/p>\n

                                \n
                              1. Only the number of database tables<\/span><\/li>\n
                              2. The records and conditions that are actually relevant to the quality requirement<\/span><\/li>\n
                              3. The number of available dashboards<\/span><\/li>\n
                              4. The age of the application<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 2<\/b><\/p>\n

                                Explanation<\/b><\/p>\n

                                The metric population should include the records and conditions relevant to the quality requirement being measured. For example, a completeness metric for a required field should clearly define which records are expected to contain that field and which legitimate exceptions are excluded. An unclear population can make results misleading because changes in the measured group may appear as quality improvement or decline. Documenting the population and calculation method ensures that measurements remain meaningful, comparable, and aligned with the intended business requirement.<\/span><\/p>\n

                                Question 396<\/b><\/h3>\n

                                Which action is most appropriate when a data quality rule conflicts with an approved business process?<\/b><\/p>\n

                                  \n
                                1. Ignore the conflict and continue reporting failures<\/span><\/li>\n
                                2. Delete the business process documentation<\/span><\/li>\n
                                3. Review the requirement, rule logic, and governance decision before changing the control<\/span><\/li>\n
                                4. Automatically disable all quality monitoring<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 3<\/b><\/p>\n

                                  Explanation<\/b><\/p>\n

                                  When a quality rule conflicts with an approved business process, the organization should review the underlying requirement and determine whether the rule or business process needs clarification. The rule may be outdated, incorrectly designed, or missing a legitimate exception. Any change should follow appropriate governance and be documented so that the control remains aligned with business requirements. Simply ignoring the conflict can create misleading quality results, while disabling all monitoring removes useful visibility. Controlled review provides a safer and more accountable resolution.<\/span><\/p>\n

                                  Question 397<\/b><\/h3>\n

                                  What is the primary purpose of documenting transformation logic during data integration?<\/b><\/p>\n

                                    \n
                                  1. To explain how source values are converted into target values<\/span><\/li>\n
                                  2. To prevent any future integration changes<\/span><\/li>\n
                                  3. To eliminate source ownership<\/span><\/li>\n
                                  4. To increase the number of source records<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 1<\/b><\/p>\n

                                    Explanation<\/b><\/p>\n

                                    Transformation documentation explains how source data is converted, mapped, filtered, formatted, or otherwise modified before reaching the target system. This information supports troubleshooting, validation, lineage, impact analysis, and reconciliation. Without documented transformation logic, it can be difficult to determine why source and target values differ or whether a difference is intentional. Documentation does not prevent future changes or eliminate ownership. Instead, it provides traceability that helps technical and business teams understand how data moves through an integration.<\/span><\/p>\n

                                    Question 398<\/b><\/h3>\n

                                    Which sign most strongly suggests that a data quality control is no longer aligned with business needs?<\/b><\/p>\n

                                      \n
                                    1. The control has a documented owner<\/span><\/li>\n

                                      Correct Answer: 4<\/b><\/p>\n

                                      Explanation<\/b><\/p>\n

                                      A material change to the business process or definition supported by a quality control can make the control outdated. The organization should reassess whether its logic, thresholds, population, and expected outcomes still match current requirements. Having an owner and periodic reviews are positive governance practices, but they do not automatically guarantee alignment after significant business changes. Controls should evolve when the meaning, usage, or creation of data changes. Reassessment helps prevent obsolete rules from producing misleading results or missing new risks.<\/span><\/p>\n

                                      4. To prevent stakeholders from reviewing the issue<\/span><\/li>\n<\/ol>\n

                                        Correct Answer: 2<\/b><\/p>\n

                                        Explanation<\/b><\/p>\n

                                        Business impact information helps stakeholders understand the consequences of a data quality issue and prioritize remediation appropriately. Two issues with similar technical characteristics may have very different levels of importance depending on the processes, customers, financial activities, or compliance obligations they affect. Business impact does not replace technical investigation; both perspectives are important. Documenting consequences also improves communication with governance stakeholders and supports risk-based decisions about remediation resources, escalation, and service-level expectations.<\/span><\/p>\n

                                        3. Continuous measurement, clear ownership, root-cause remediation, and periodic governance review<\/span><\/li>\n
                                        4. Disabling controls after the first improvement<\/span><\/li>\n<\/ol>\n

                                          Correct Answer: 3<\/b><\/p>\n

                                          Explanation<\/b><\/p>\n

                                          Effective data quality management is an ongoing discipline rather than a one-time cleanup exercise. Continuous measurement provides visibility into current performance, while clear ownership establishes accountability for addressing issues. Root-cause remediation reduces recurring problems instead of repeatedly correcting symptoms. Periodic governance reviews ensure that rules, thresholds, definitions, and priorities remain aligned with business needs. Combining these practices creates a sustainable quality management cycle that supports prevention, detection, remediation, and continuous improvement across important data domains and sources.<\/span><\/p>\n
