A DMZ (Demilitarized Zone) is a network segment that acts as a buffer between the public internet and an organization’s internal systems, protected by two firewalls. The DAMA-DMBOK explains: “A DMZ is typically configured with two firewalls: one between the DMZ and the external internet, and another between the DMZ and the internal network, to secure internal systems from external threats” (DMBOK2, Chapter 8: Data Security, p. 303).

Options A, B, C, and E are incorrect: A is nonsensical; B is vague; C includes the extranet, which is not standard; and E uses “intranet,” which is less precise than “internal systems.”

A business glossary aims to standardize data definitions and improve data usage, not to define organizational structures or software. The DAMA-DMBOK states: “The objectives of a business glossary include providing standard definitions for data and metadata, maximizing searchability, linking physical assets to business concepts, and reducing misuse due to inconsistent definitions” (DMBOK2, Chapter 11: Metadata Management, p. 445). Option E is unrelated to glossary objectives.

Rationalizing party concepts across systems requires a strong data architecture to standardize data models and data governance to enforce policies. The DAMA-DMBOK states: “Data architecture provides the framework for standardizing data entities, such as party concepts, while data governance ensures compliance and consistency across systems during rationalization efforts” (DMBOK2, Chapter 4: Data Architecture, p. 145; Chapter 3: Data Governance, p. 109).

Options A, B, C, and D are less comprehensive: operations (A) and warehousing (D) are tactical, quality (B) is a benefit, and metadata (C) is supportive but not primary.
