OGEA-103 Exam Questions & Answers

Correct Answer: C

Explanation: The scope of an architecture is the extent and level of detail of the architecture work. The scope of an architecture can be defined along four dimensions:

project, breadth, depth, and architecture domains. The project dimension considers the boundaries and objectives of the architecture project, such as the time frame, budget, resources, and deliverables. The breadth dimension considers the

coverage and completeness of the architecture across the enterprise, such as the organizational units, business functions, processes, and locations. The depth dimension considers the level of detail and specificity of the architecture, such as

the granularity, abstraction, and precision of the architectural elements and relationships. The architecture domains dimension considers the aspects or segments of the architecture, such as the business, data, application, and technology

domains.

Therefore, the depth dimension is the one that considers to what level of detail the architecting effort should go.

Correct Answer: C

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:

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

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

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

D: Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Technology Architectures References: 1: The TOGAF Architecture Development Method

Correct Answer: B

Explanation: The Target Architecture is a description of the future state of the architecture that addresses the business goals and drivers, and satisfies the stakeholder requirements and concerns. The Target Architecture is developed through the Architecture Development Method (ADM), which is the core process of the TOGAF standard that guides the development and management of the enterprise architecture. The Target Architecture is typically divided into four domains: Business, Data, Application, and Technology. The Target Architecture also includes a roadmap for change, which defines the Transition Architectures, the Capability Increments, and the work packages that enable the transition from the Baseline Architecture to the Target Architecture12 The best answer is B, because it describes the approach that should be taken to determine and organize the work to deliver the requested architectures, which are the Information Systems and Technology Architectures. The answer covers the following steps: Refer to the end-to-end Target Architecture for guidance and direction. The end-to- end Target Architecture provides the overall vision, scope, and objectives of the architecture work, and the alignment with the business strategy and goals. The end-to-end Target Architecture also provides the high-level definitions and principles for the four architecture domains, and the roadmap for change that outlines the major milestones and deliverables. Identify projects, dependencies and synergies, then prioritize before initiating the projects. Projects are the units of work that implement the architecture work packages, which are the sets of actions or tasks that are required to implement a specific part of the architecture. Dependencies are the relationships and constraints that affect the order or priority of the projects, such as logical, temporal, or resource dependencies. Synergies are the benefits or advantages that result from the combination or coordination of the projects, such as cost savings, efficiency gains, or innovation opportunities. Prioritization is the process of ranking the projects according to their importance, urgency, or value, and assigning resources and schedules accordingly. Develop high-level architecture descriptions. High-level architecture descriptions are the outputs of the architecture development phases (B, C, and D) of the ADM cycle, which describe the Business, Data, Application, and Technology Architectures in terms of the Architecture Building Blocks (ABBs) and the Solution Building Blocks (SBBs), which are reusable components of business, IT, or architectural capability. High-level architecture descriptions also include the Architecture Views, which are representations of the system of interest from the perspective of one or more stakeholders and their concerns. For each project, estimate effort size, identify reference architectures, and candidate building blocks. Effort size is the measure of the amount of work, time, or resources required to complete a project. Effort size can be estimated using various techniques, such as analogy, expert judgment, parametric, or bottom-up. Reference architectures are standardized architectures that provide a common framework and vocabulary for a specific domain or industry. Reference architectures can be used as a source of best practices, patterns, and models for the architecture development. Candidate building blocks are the potential ABBs or SBBs that can be used to implement the architecture. Candidate building blocks can be identified from the Architecture Repository, which is a collection of architecture assets, such as models, patterns, principles, standards, and guidelines. Identify the resource needs considering cost and value. Resource needs are the specifications and criteria that define the acceptable level and quality of the resources required to complete the project, such as human, financial, physical, or technological resources. Resource needs can be identified by analyzing the scope, complexity, and dependencies of the project, and the availability, capability, and suitability of the resources. Cost and value are the factors that influence the allocation and utilization of the resources, such as the budget, the return on investment, the benefits, or the risks. Document options, risks, and controls to enable viability analysis and trade-off with the stakeholders. Options are the alternative ways of achieving the project objectives, such as different solutions, technologies, vendors, or approaches. Risks are the effects of uncertainty on the project objectives, such as threats or opportunities. Controls are the measures or actions that are taken to prevent, reduce, or mitigate the risks, such as policies, procedures, or standards. Viability analysis is the process of evaluating and comparing the options, risks, and controls, and determining the feasibility, suitability, and desirability of each option. Trade-off is the decision outcome that balances and reconciles the multiple, often conflicting, requirements and concerns of the stakeholders, and ensures alignment with the Architecture Vision and the Architecture Principles.
