C. Lifecycle projection.
D. Vertical mapping / model lineage.
DA4-017 — EDM · Standard · Distinguish

Which rule about Subject Areas is supported by Chapter 4?
A. An entity should be duplicated into every Subject Area that uses it.
B. Each entity should reside in only one Subject Area, though it may relate to entities in other Subject Areas.
C. Subject Areas should always be based on application ownership.
D. Subject Areas cannot have relationships with one another.

What does a top-down approach to building the enterprise data model start with?
A. Reverse engineering all COTS systems first.
B. Building only project physical models and never an enterprise model.
C. Forming Subject Areas and then populating them with models.
D. Starting from existing data models and deriving the Subject Area structure.
DA4-020 — EDM · Difficult · Apply
Which statement best reflects Chapter 4's guidance on forming Subject Areas?
A. Always base Subject Areas on whichever application budget pays for them.
B. Use a different discriminator for each business unit to maximize local fit.
C. Never use governance ownership or business capabilities as a discriminator.
D. Use a consistent discriminator across the enterprise; normalization is usually most effective for Data Architecture work.
DA4-021 — Data Flow · Standard · Recall
What do end-to-end data flows primarily illustrate?
A. Where data originates, where it is stored and used, and how it transforms as it moves through processes and systems.
B. Only who approves each data policy.
C. Only physical network latency between servers.
D. Only conceptual entity relationships.
DA4-022 — Data Flow · Standard · Apply
A data-flow artifact identifies which business roles create, read, update, and delete Customer data. Which Chapter 4 concept is this using?
A. Zachman motivation mapping.
B. CRUD responsibility mapping within Data Flow Design.
C. Architecture standard compliance.
D. Subject Area normalization.
DA4-023 — Data Flow · Difficult · Distinguish
Why might a two-dimensional process/data matrix be especially useful?
A. It guarantees that all data flows in one direction.
B. It eliminates the need for any data-flow diagrams.
C. It clearly shows many-to-many create/use relationships, acquisition responsibility, and dependencies between processes.
D. It is required only for network-security mapping.
DA4-024 — Activities · Standard · Distinguish
Which statement best describes a quality-oriented architecture approach?
A. It prioritizes unproven business logic and leading-edge technology over architecture quality.
B. It ignores governance and standards so projects can move faster.
C. It avoids long-term goals in favor of short experiments.
D. It focuses on improving execution, preventing architecture deterioration, standardization, and structured long-term development.
DA4-025 — Activities · Standard · Apply

A. Innovation-oriented architecture.
B. Quality-oriented architecture only.
C. Lifecycle retirement planning.
D. Architecture standards compliance measurement.
DA4-026 — Practice · Standard · Recall
Which list contains the five work streams of an Enterprise Data Architecture practice described in Chapter 4?
A. Plan; acquire; build; test; operate.
B. Strategy; acceptance and culture; organization; working methods; results.
C. Business; data; application; technology; security.
D. Current; target; transition; preferred; retired.
DA4-027 — Practice · Difficult · Apply
A project has conceptual, logical, and physical models. What does Chapter 4 say an architecture design review should ensure?
A. That every project uses identical physical database structures.
B. That architects take over all project implementation tasks.
C. That project data designs are consistent with architecture and support long-term organizational strategy.
D. That no project can introduce new enterprise entities.
DA4-028 — Practice · Difficult · Apply
Why does Chapter 4 treat data replication as an architecture-governance concern?
A. Replication is always prohibited in enterprise architecture.
B. Every replicated copy must have strict consistency regardless of business need.
C. Replication is solely a network-architecture issue.
D. Replication can improve performance/availability but can also create inconsistency, so architecture must ensure sufficient control for the required consistency level.
