CompTIA Data+ DA0-002 (V2) Practice Question

The correct answer is to establish a single source of truth (SSoT). A SSoT is a central, authoritative data repository that an entire organization can use for a specific data element, eliminating discrepancies between different systems. In this scenario, designating either the CRM or the accounting software (or a new, consolidated data warehouse) as the definitive source for revenue figures would resolve the conflict.

• Increasing the data refresh interval would only update the conflicting numbers more frequently; it would not resolve the underlying discrepancy.
• Creating a data dictionary is a useful documentation practice that describes data and its attributes, but it does not enforce consistency or resolve conflicts between data sources.
• Role-based access control is a security measure that restricts data access based on a user's role within the organization. It is unrelated to solving issues of data accuracy or consistency between different systems.
