These domains provide a consistent way to describe and understand the architecture from different perspectives, such as business, information, and technology12. Each domain has its own set of concepts, models, views, and artifacts that define the structure and behavior of the architecture within that domain12.

The other options are incorrect because:

•Logical and Physical are not architecture domains, but rather levels of abstraction that can be applied to any domain. Logical architecture describes the functionality and behavior of the system, while physical architecture describes the implementation and deployment of the system3.

•Information and Data are not distinct architecture domains, but rather aspects of the same domain. Information architecture describes the meaning and context of the data, while data architecture describes the structure and format of the data4.

•Capability and Segment are not architecture domains, but rather levels of granularity that can be applied to any domain. Capability architecture describes the current and desired states of a specific business capability, while segment architecture describes a subdivision of the enterprise that has a clear business focus5.

The purpose of Enterprise Architecture is to guide effective change by providing a coherent and consistent view of the enterprise’s current and future state, as well as the roadmap and principles for achieving it. Enterprise Architecture helps to align business and IT strategies, optimize resources and investments, reduce complexity and risks, enhance agility and innovation, and deliver value to stakeholders.

Strategy Portfolio Project Solution Delivery are the four purposes that typically frame the planning horizon, depth and breadth of an Architecture Project, and the contents of the EA Repository. They correspond to different levels of abstraction and granularity in the architecture development process. Reference: The TOGAF® Standard, Version 9.2 - The Open Group, Section 2.4 Architecture Repository.

Enterprises are examples of the scope of an architecture according to the TOGAF Standard. An enterprise is defined as any collection of organizations that has a common set of goals and/or asingle bottom line. Enterprises can be whole corporations or divisions of a corporation, government agencies or single government departments, partnerships and alliances of businesses working together, etc. Reference: The TOGAF® Standard | The Open Group Website, Section 2.1 Core Concepts.

Risk is defined as the effect of uncertainty on objectives, according to the ISO 31000 standard, which provides principles and guidelines for risk management1 Risk can be positive or negative, depending on whether the uncertainty affects the achievement or the failure of the objectives. Risk can also be expressed in terms of likelihood and impact, which indicate the probability and the consequence of the risk occurrence. Risk management is the coordinated activities to direct and control an organization with regard to risk. Risk management is an integral part of the TOGAF standard, as it helps to identify, assess, and treat the risks that may affect the architecture development and implementation2 References: 1: ISO 31000:2018, Riskmanagement — Guidelines, Clause 3.1 2: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 32: Risk Management

An Enterprise Architecture Capability is the ability of the organization to perform effective and efficient architecture work, including the definition, governance, and management of its architectures2. The Preliminary Phase involves the following activities1:

•Reviewing the organizational context, scope, and drivers for conducting Enterprise Architecture

•Establishing the Architecture Capability desired by the organization, including the maturity level, roles, responsibilities, processes, and tools

•Defining and establishing the Organizational Model for Enterprise Architecture, which describes how the architecture function is organized and integrated within the enterprise

•Defining and establishing the Architecture Governance framework, which provides the mechanisms for ensuring the quality, consistency, and compliance of the architecture work

•Selecting and implementing the tools that support the Architecture Capability, such as repositories, modeling tools, and communication tools

•Defining the Architecture Principles that will guide and constrain the architecture work, based on the business principles, goals, and drivers of the organization

•Defining the Organization-Specific Architecture Framework, which is an adaptation of the generic TOGAF ADM to suit the specific requirements, standards, and practices of the organization

The Preliminary Phase is essential for preparing the organization for the successful development and implementation of its architectures, as well as for ensuring the alignment of the architecture work with the business strategy and objectives1.

According to the TOGAF Standard, 10th Edition, architecture governance is “the practice by which enterprise architectures and other architectures are managed and controlled at an enterprise-wide level” 1. Architecture governance ensures that the architecture development and implementation are aligned with the strategic objectives, principles, standards, and requirements of the enterprise, and that they deliver the expected value and outcomes. Architecture governance also involves establishing and maintaining the architecture framework, repository, board, contracts, and compliance reviews 1. The other options are not correct, as they are not the term used by the TOGAF Standard to describe the practice by which the enterprise architecture is managed and controlled at an enterprise-wide level. Corporate governance is “the system by which an organization is directed and controlled” 2, and it covers aspects such as leadership, strategy, performance, accountability, and ethics. IT governance is “the system by which the current and future use of IT is directed and controlled” 2, and it covers aspects such as IT strategy, policies, standards, and services. Technology governance is “the system by which the technology decisions and investments are directed and controlled” 3, and it covers aspects such as technology selection, acquisition, deployment, and maintenance.
