The four dimensions used to scope an architecture are Breadth, Depth, Time Period, and Architecture Domains1, p. 8.
Breadth refers to the extent of the enterprise covered by the architecture, which can range from a specific business unit to the entire organization1, p. 8.
Depth refers to the level of detail and completeness of the architecture, which can vary depending on the purpose, scope, and stakeholders of the architecture1, p. 8.
Time Period refers to the temporal aspects of the architecture, such as the current state, the target state, and the transition plan1, p. 8.
Architecture Domains refers to the classification of the architecture into four domains: Business, Data, Application, and Technology1, p. 8.
These four dimensions help define the scope and boundaries of the architecture and ensure that it meets the needs and expectations of the stakeholders.

*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 References: 1: The TOGAF Architecture Development Method

According to the TOGAF standard, the objectives of each ADM phase are as follows1:
*Phase E: Opportunities and Solutions
oDetermine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value oIdentify and group major work packages within the Architecture Roadmap oIdentify and group major implementation projects to realize the Architecture Roadmap oIdentify dependencies between increments and projects oEstimate cost, benefit, and risk at a high level for each increment and project oConduct initial prioritization and sequencing of the Architecture Roadmap and projects
*Phase F: Migration Planning
oGenerate the initial complete version of the Architecture Roadmap, based upon the gap analysis and candidate Architecture Roadmap components from Phases B, C, and D oConfirm the Transition Architectures with relevant stakeholders oCreate the Implementation and Migration Plan, including Transition Architectures, work packages, projects, and other activities oConfirm and agree the Architecture Roadmap and Implementation and Migration Plan with relevant stakeholders
*Phase G: Implementation Governance
oFinalize the Architecture Roadmap and the supporting Implementation and Migration Plan oEnsure conformance with the Target Architecture by implementation projects oPerform appropriate Architecture Governance functions for the solution and any implementation-driven architecture Change Requests oEnsure that the architecture lifecycle is maintained oEnsure that the Architecture Governance Framework is executed
*Phase H: Architecture Change Management
oEnsure that the business value and cost of work packages and Transition Architectures is understood by key stakeholders oManage risks and issues related to the Architecture Roadmap and Implementation and Migration Plan oMonitor the implementation projects and Transition Architectures oManage changes to the architecture baseline oManage changes to the Architecture Capability Therefore, the correct matching of the objectives and the phases is:
*1G: Determine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value
*2E: Generate the initial complete version of the Architecture Roadmap, based upon the gap analysis and candidate Architecture Roadmap components from Phases B, C, and D
*3F: Finalize the Architecture Roadmap and the supporting Implementation and Migration Plan
*4F: Ensure that the business value and cost of work packages and Transition Architectures is understood by key stakeholders References: 1: The TOGAF Architecture Development Method

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.

Concerns are interests important to the stakeholders in a system. They are used to identify and classify the system's stakeholders and to guide the selection of viewpoints for the architecture description. Reference: The TOGAF Standard | The Open Group Website, Section 3.2.1 Architecture Viewpoints
