CompTIA Data+ Certification (DAO-002) Practice Test

In data governance, documenting data sources and communicating data limitations is all about metadata management and data lineage. By capturing where data comes from, how it was collected, what transformations were applied, and any known constraints (such as timeliness, completeness, or biases), you create context that helps data producers, stewards, and users evaluate trustworthiness and appropriate use. This transparency supports data quality, compliance, and informed decision-making, since people know the provenance and limits of the data they rely on. The other activities focus on infrastructure and operations rather than governance documentation: building storage hardware relates to system capacity and architecture, configuring firewall rules pertains to security, and performing backups deals with data resilience and recovery. While important, they don’t embody the governance practice of documenting sources and communicating limitations.
