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

In TOGAF, Architecture Principles are created to provide a clear and stable foundation for architecture work across the enterprise. Their purpose is to guide decision-making and establish a shared understanding of the rules and boundaries within which architecture and business change should take place. The best answer is A because Architecture Principles are intended to create a common basis for governance and direction, ensuring that architecture supports the control and evolution of the enterprise in line with its strategic goals.

Option B is incorrect because documenting likely impacts belongs more appropriately to the Implications section of an individual principle, not to the overall purpose of creating a set of principles. Option C is also incorrect because while principles may reflect aspects of enterprise culture and values, that is not their main purpose. Option D refers more closely to an Architecture Contract, which is a formal agreement between sponsors and architects or implementation organizations.

A defined set of principles helps ensure consistency, improves governance, supports compliance, and aligns architecture decisions with business direction. In this way, principles act as a decision framework for the enterprise. Therefore, the correct completion of the sentence is establish a common understanding of how to control the business in pursuit of strategic goals.

•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 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

The chart illustrates an important TOGAF concept: ADM phases can operate concurrently or iteratively rather than strictly sequentially. The diagram shows Phase A activities occurring first, after which the architecture development phases (Business, Data, Application, and Technology Architectures) overlap in time. This overlap demonstrates how architecture development work may proceed in parallel as information becomes available, allowing architects to refine and coordinate the candidate architecture more efficiently.

TOGAF explicitly supports iteration and concurrency across ADM phases. While the phases are presented in a logical order, they are not intended to be executed in a rigid step-by-step sequence in all situations. Instead, architects may work across several phases simultaneously to address dependencies, refine requirements, and accelerate the development of the candidate architecture and roadmap.

Option A best reflects this principle because it acknowledges that phases may run together as part of an iterative architecture development process until a coherent candidate architecture is produced and validated. Option B is incorrect because TOGAF does not mandate the use of specific project management tools such as Gantt charts. Option C is incorrect because the ADM is not strictly sequential. Option D is incorrect because the duration of phases is not fixed in TOGAF.

Therefore, the chart illustrates the concept that ADM phases may be executed concurrently to develop and validate the candidate architecture.
