The Open Group Updated OGEA-101 Exam Questions and Answers by fergus

The TOGAF standard divides Enterprise Architecture into four primary architecture domains: business, data, application, and technology. These domains represent different aspects of an enterprise and how they relate to each other. The business domain defines the business strategy, governance, organization, and key business processes. The data domain describes the structure of the logical and physical data assets and data management resources. The application domain provides a blueprint for the individual applications to be deployed, their interactions, and their relationships to the core business processes. The technology domain describes the logical software and hardware capabilities that are required to support the deployment of business, data, and application services. Other domains, such as motivation, security, or governance, may span across these four primary domains. References:

TOGAF and the history of enterprise architecture | Enable Architect

In the TOGAF Standard, the concept of an Enterprise Architecture is broken into several primary architecture domains. These domains provide a structured way to describe the enterprise from multiple perspectives that collectively support transformation and governance. TOGAF specifies four core architecture domains: Business Architecture, Data Architecture, Application Architecture, and Technology Architecture. These domains, when combined, form a comprehensive view of how the enterprise functions, how information flows, how systems interact, and what technologies support the organization.

Among the choices provided, only Business and Technology are officially recognized architecture domains in TOGAF. The Business Architecture describes business strategy, governance, organization, and key processes. The Technology Architecture defines the logical and physical technology infrastructure necessary to support mission-critical applications and data. The other answer options do not represent TOGAF architecture domains; for example, “Strategy,” “Vision,” “Target,” or “Digital” are not formal architecture domains in TOGAF. Thus, the pair that correctly identifies subsets of an enterprise architecture according to the TOGAF framework is Business and Technology Architecture.

Comprehensive and Detailed Explanation From documents:

The Architecture Repository in TOGAF provides a structured model for storing architectural output. It contains six classes of architectural information:

Architecture Metamodel – defines the structure of architectural content and relationships.

Architecture Capability – contains parameters, structures, and processes supporting the governance of the repository and the Architecture Board.

Architecture Landscape – architectural views at different levels (Strategic, Segment, Capability).

Standards Information Base (SIB) – standards to guide architecture development and solution building.

Reference Library – reference materials such as patterns, templates, guidelines.

Governance Log – record of governance activity, compliance assessments, waivers, and approvals.

Focusing on Architecture Capability:

Defined by TOGAF as: “The parameters, structures, and processes that support governance of the Architecture Repository.”

It provides the framework for ensuring that the repository is managed, controlled, and aligned with the enterprise’s architecture governance practices.

It includes organizational roles, responsibilities, and processes that ensure architecture practices are sustainable and repeatable.

Why the other options are incorrect:

B. This describes the Architecture Metamodel, not Architecture Capability.

C. This describes the Governance Log, which holds the record of governance activity.

D. This describes the Reference Library, which contains patterns, templates, and guidelines.

Comprehensive and Detailed Explanation From documents:

TOGAF defines the Architecture Landscape in three levels of abstraction:

Strategic Architectures (A):

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 1 (Direction setting at an executive level) → belongs to Strategic Architectures (A).

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:

B = 2 → Correct (Segment = Roadmap development).

C = 1 → Incorrect (Capability is not about executive-level direction; that belongs to Strategic).

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.
