The Open Group TOGAF Enterprise Architecture Part 1 Exam (English) OGEA-101 Exam Dumps: Updated Questions & Answers (October 2025)

Statements 1 and 3 about architecture partitioning are correct. Architecture partitioning is the technique of dividing an architecture into smaller and more manageable parts that can be developed, maintained, and governed independently. Partitions are used to simplify the management of the Enterprise Architecture and to enable different teams to work on different elements of the architecture at the same time. Partitions are not equivalent to architecture levels, which are different degrees of abstraction or detail in an architecture. Partitions do not necessarily reflect the organization’s structure, which may change over time or differ from the architecture’s scope and boundaries. Reference: The TOGAF® Standard | The Open Group Website, Section 2.5 Architecture Partitioning.

Comprehensive and Detailed Explanation

In TOGAF, Architecture Contracts are agreements between development partners and sponsors that define:

The deliverables to be produced.

The quality expectations.

The fitness-for-purpose of the architecture.

The responsibilities of each party and the governance arrangements.

Architecture Contracts are a key part of Phase G: Implementation Governance, where they are used to manage and control architecture implementation. They help ensure that implementation projects remain aligned with the approved Target Architecture and business objectives.

They serve as the formal mechanism for:

Validating that architecture deliverables meet stakeholder expectations.

Providing a measurable basis for conformance assessment.

Supporting architecture governance by linking architectural intent with project execution.

Why the other options are incorrect

B. The Statement of Architecture Work: This defines the scope, approach, resources, and schedule for architecture work, but it is not a joint agreement on deliverables and fitness-for-purpose.

C. Service Level Agreements (SLAs): These are agreements about operational service levels (e.g., availability, performance), not architecture deliverables.

D. Non-disclosure Agreement (NDA): This protects confidentiality of information but does not address deliverables, quality, or fitness-for-purpose of an architecture.

The TOGAF Content Framework defines a detailed model of architectural work products (artifacts, deliverables, building blocks) and the relationships between them.

It is not a lifecycle management capability (A), that is related to the ADM itself.

It is not organized strictly by ADM phases (B).

It is not fixed; it is designed to be tailored (C).

The planning horizon, depth, and breadth of an Architecture Project, along with the contents of the EA Repository, are typically framed by Strategy, Portfolio, Segment, and End-to-end Target Architecture. The 'Segment' refers to a part of the organization, typically addressed in a Segment Architecture, while 'End-to-end Target Architecture' encompasses the complete view of the planned architecture across the entire organization.

The objective of the ADM Implementation Governance Phase is to provide an architectural oversight of the implementation and to ensure conformance for the target architecture. This phase involves establishing procedures and processes to monitor and control the implementation projects and to verify that they comply with the defined architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2.7 Phase G: Implementation Governance.

The purpose of the Architecture Roadmap is to provide a high-level view of how the Baseline Architecture will transition to the Target Architecture over time. It lists work packages on a timeline showing progress towards the Target Architecture, as well as dependencies, risks, and benefits. The Architecture Roadmap forms part of the Implementation and Migration Plan and guides the execution of the architecture projects.

The Implementation Governance Model is a framework that defines the roles, responsibilities, processes, and standards for governing the implementation of the target architecture. It ensures that a project transitioning into implementation also smoothly transitions into appropriate Architecture Governance, which is the practice of ensuring compliance with the enterprise architecture and its principles, standards, and goals. The Implementation Governance Model is part of the Implementation and Migration Plan, which is the output of Phase F: Migration Planning of the Architecture Development Method (ADM)12 References: 1: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 21: Phase F: Migration Planning 2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 50: Architecture Governance
