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

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

According to the TOGAF standard, the need for the ADM process to be governed is to ensure that the architecture development and implementation activities are conducted in a consistent, coherent, and compliant manner1. Governance provides the means to verify that the method is being applied correctly and effectively, and that the architecture deliverables and artifacts meet the quality and standards criteria1. Governance also enables the management of risks, issues, changes, and dependencies that may arise during the ADM process1.

Some of the benefits of governing the ADM process are2:

•Improved alignment of the architecture with the business strategy and objectives

•Enhanced stakeholder engagement and communication

•Increased reuse and integration of architecture assets and resources

•Reduced complexity and duplication of architecture efforts

•Increased agility and adaptability of the architecture to changing needs and requirements

•Improved compliance and auditability of the architecture outcomes and outputs

•Phase A: Architecture Vision

oDevelop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed Enterprise Architecture

oDefine the scope and boundaries of the architecture engagement

oIdentify the key stakeholders and their concerns and expectations

oDefine the Architecture Vision statement and the Architecture Definition Document

oObtain approval and commitment from the sponsors and stakeholders

•Phase B: Business Architecture

oDevelop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals

oDefine the Baseline Business Architecture, if not available

oPerform a gap analysis between the Baseline and Target Business Architectures

oDefine candidate roadmap components for the Business Architecture

oResolve impacts across the Architecture Landscape

•Phase C: Information Systems Architecture

oDevelop the Target Data Architecture that enables the Business Architecture and the Architecture Vision

oDevelop the Target Application Architecture that supports the Business Architecture and the Architecture Vision

oDefine the Baseline Data and Application Architectures, if not available

oPerform a gap analysis between the Baseline and Target Data and Application Architectures

oDefine candidate roadmap components for the Information Systems Architecture

oResolve impacts across the Architecture Landscape

•Phase D: Technology Architecture

oDevelop the Target Technology Architecture that enables the Information Systems Architecture and the Architecture Vision

oDefine the Baseline Technology Architecture, if not available

oPerform a gap analysis between the Baseline and Target Technology Architectures

oIdentify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Technology Architectures

oResolve impacts across the Architecture Landscape

Therefore, the correct matching of the objectives and the phases is:

•1C: Develop the Target Data Architecture that enables the Business Architecture and the Architecture Vision

•2B: Develop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals

•3A: Develop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed Enterprise Architecture

•4D: Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Technology Architectures

The graphic represents the Architecture Alternatives and Trade-off technique described in the TOGAF ADM guidelines. This technique evaluates different architecture options against defined criteria derived from the Architecture Vision, Architecture Principles, and Requirements. The purpose of the method is to identify and compare multiple potential architecture approaches before selecting the most appropriate one.

In practice, architects generate several candidate architectures that could meet the enterprise’s needs. Each alternative is evaluated against criteria such as business value, risk, cost, compliance with principles, and alignment with requirements. Through structured comparison, stakeholders can understand the strengths and weaknesses of each alternative and select the most suitable architecture direction.

Because the evaluation process focuses on different architectural approaches for achieving the target state, the method is used to identify Alternative Target Architectures. These alternatives represent different ways the enterprise could structure its future architecture before committing to a single preferred solution.

The other options do not match the purpose of the diagram. Business Scenarios are used to understand requirements, Solution Building Blocks are implementation components, and Architecture Solutions represent final implementation outcomes rather than competing architecture options. Therefore, the method illustrated helps identify Alternative Target Architectures, making Option B the correct answer.
