OGEA-101 Exam Dumps - TOGAF Enterprise Architecture Part 1 Exam (English)

In the TOGAF Standard, a well-defined architecture principle must meet several quality criteria, such as understandability, robustness, completeness, and consistency. The criterion most closely associated with a principle being definitive, precise, and reliable under complex decision-making conditions is Robustness. TOGAF describes robustness as the characteristic that ensures the principle provides clear guidance even when applied across a variety of scenarios, stakeholder viewpoints, and architectural complexities. A robust principle remains valid and usable regardless of changes in context or external pressures.

Where other criteria focus on different aspects—such as Stability (long-term applicability), Completeness (covering all necessary aspects of the principle’s intent), and Consistency (avoiding conflict with other principles)—it is Robustness that specifically ensures a principle is sufficiently strong and precise to support consistent decisions in complex environments. This means a robust principle minimizes ambiguity, avoids subjective interpretation, and provides architects with a dependable rule that can be repeatedly applied across multiple architecture domains and transformation projects. By being robust, a principle becomes a dependable instrument for governance and architectural alignment at the enterprise level.

Architecture Requirements Specification: “provides a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture.” Open Group Publications

Statement of Architecture Work (Phase A output): “The Statement of Architecture Work defines the scope and approach that will be used to complete an architecture project.” (Produced in Phase A per the Phase A outputs list.) Open Group Publications

Statements 1 and 3 highlight the value and necessity for Architecture Governance to be adopted within organizations. Architecture Governance is the practice and orientation by which Enterprise Architectures and other architectures are managed and controlled at an enterprise-wide level12. It ensures that architectural decisions are aligned with the organization’s strategy, objectives, and standards. Architecture Governance also involves establishing and maintaining processes, decision-making, and mechanisms to avoid or minimize potential conflicts of interest, such as between different stakeholders, business units, or projects34. Moreover, Architecture Governance requires transparency and accountability for all actions implemented and their decision support, so that they can be inspected and evaluated by authorized parties, such as auditors, regulators, or customers5 .

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.

The Architecture Landscape is a class of information within the Architecture Repository that shows an architectural view of the building blocks that are in use within the organization today (the Baseline Architecture), as well as those that are planned for the future (the Target Architecture). The Architecture Landscape typically contains a list of the applications in use within the enterprise, along with their relationships and dependencies, as well as other relevant architectural information. The Architecture Landscape helps to identify opportunities for re-use, consolidation, or retirement of existing applications, as well as gaps or overlaps in the current or future architecture.

The TOGAF ADM uses Gap Analysis during Phases B, C, and D (Business, Information Systems, and Technology Architectures) to identify building block gaps—the differences between the Baseline Architecture and the Target Architecture. However, simply identifying gaps does not complete the process.

The association of gaps with work packages happens later in the cycle:

Phase E: Opportunities and Solutions is where the identified gaps are analyzed and translated into work packages, projects, or initiatives that will deliver the required changes.

In Phase E, architects also determine whether Transition Architectures are needed, and they generate the initial Architecture Roadmap.

This is the phase where gaps become actionable, linked with specific work packages that can be executed to close them.

Phase F (Migration Planning) takes this further by finalizing the roadmap and building the detailed Implementation and Migration Plan, but the initial association of gaps with work packages occurs in Phase E.

TOGAF’s governance guidance distinguishes benefits such as transparency, accountability, and discipline in operating governance processes. Formal TOGAF conformance topics include “The benefits of Architecture Governance,” which include establishing and enforcing processes and controls (discipline) for architecture decision-making and compliance. togaf-cert.opengroup.org
