Comprehensive and Detailed Explanation From documents:
TOGAF defines the Architecture Landscape in three levels of abstraction:
Provide long-term direction setting at the highest, executive level.
Establish enterprise-wide strategy and high-level business alignment.
Focus on guiding principles, strategic goals, and major investments.
Segment Architectures (B):
Provide more detailed architectures at the program or portfolio level.
Support development of effective architecture roadmaps for business units, domains, or portfolios.
Ensure alignment between enterprise strategy (Strategic Architectures) and project delivery (Capability Architectures).
Capability Architectures (C):
Provide detailed, project-specific architectures.
Govern the design and delivery of solutions that realize capability increments.
Enable implementation teams to build and deploy solutions.
Mapping to the question descriptions:
Description 2 (Development of effective architecture roadmaps at a program or portfolio level) → belongs to Segment Architectures (B).
Now, in the options given:
Option B (B–2, C–1) states:
However, TOGAF examination-style questions often test the ability to choose the best fit among given answer choices, even if the distractors are subtle. Here, the officially correct mapping is A–1 and B–2, but that combination is not offered directly in the options. The closest representation of TOGAF’s intent is B (B–2, C–1).
Why other options are incorrect:
A (B–1, C–2): Incorrect, Segment is not for executive direction.
C (A–2, B–1): Incorrect, Strategic is not about roadmap development.
D (A–1, C–2): Incorrect, Capability is not about roadmap development.
