DMF-1220 Exam Dumps - Data Management Fundamentals

During initial project scoping, a data model, particularly a conceptual or logical model, helps define the scope by identifying which data entities are affected or unaffected by the project. The DAMA-DMBOK states: “Data models are used in project scoping to define the boundaries of the data domain, identifying affected entities and their relationships to ensure alignment with business requirements” (DMBOK2, Chapter 5: Data Modeling and Design, p. 181).

Other options are less accurate: A is too broad, as models support but don’t directly determine process impacts; B involves detailed physical modeling, not initial scoping; C relates to metadata management; and E pertains to security, not scoping.

Integrating multiple source systems is challenging due to the need to identify valid links or equivalences between data elements across systems (e.g., matching customer IDs). The DAMA-DMBOK states: “A key challenge in data integration is determining equivalences between data elements from disparate sources, requiring mapping and transformation to ensure consistency” (DMBOK2, Chapter 13: Data Integration and Interoperability, p. 513).

Options A, C, D, and E are challenges but less central: documentation (A) is operational, modifying systems (C) is often impractical, universal rules (D) are difficult but secondary, and architecture timing (E) is project-related.

Sensitive data, such as addresses, can be disclosed if software fails to enforce privacy tags or metadata that indicate data sensitivity. The DAMA-DMBOK emphasizes that data security involves “protecting data from unauthorized access or disclosure through controls such as access policies, encryption, and metadata-driven privacy enforcement” (DMBOK2, Chapter 8: Data Security, p. 297). Privacy tags are metadata attributes that signal how data should be handled, and software ignoring these tags can lead to unauthorized exposure.

Options A, B, D, and E are less directly related. For example, inappropriate use of photocopier toner (A) is unrelated to data security in this context, and cloud-based databases (B) are a platform, not a direct cause of disclosure unless misconfigured. Ineffective data architecture (D) or stored procedures (E) may contribute indirectly but are not as specific as software ignoring privacy tags.
