CDMP Exam Relevance

Data governance tools and platforms are tested across multiple CDMP knowledge areas. The CDMP exam does not test specific vendor products but does test candidates' understanding of tool categories, capabilities, and selection criteria. Key exam topics include: the categories of data governance tools, the capabilities of data catalog and MDM platforms, and the governance requirements that tools must support. Understanding the tool landscape is important for Data Architecture and Data Governance maturity questions.
