Question #1
Which of the following is the ability to develop use and sustain the architecture of a particular enterprise using architecture to govern change?
- A . An EA Capability
- B . An EA repository
- C . An EA framework
- D . An Enterprise Architecture
Correct Answer: A
A
Explanation:
The ability to develop, use, and sustain the architecture of a particular enterprise using architecture to govern change is an EA Capability. An EA Capability is a set of skills, processes, roles, responsibilities, tools, and techniques that enable an enterprise to successfully develop and maintain its Enterprise Architecture and achieve its desired outcomes. An EA Capability is part of an enterprise’s overall capability portfolio and should be aligned with its strategy and objectives.

Question #2
Which of the following statements about architecture partitioning is correct?
- A . Partitions are used to simplify the management of the Enterprise Architecture.
- B . Partitions are equivalent to architecture levels.
- C . Partitions reflect the organization’s structure.
- D . Partitions are defined and assigned to agile Enterprise Architecture teams.
Correct Answer: A
A
Explanation:
Based on the web search results, architecture partitioning is a technique that divides the Enterprise Architecture into smaller and manageable segments or groups, based on various classification criteria, such as subject matter, time, maturity, volatility, etc.12 Architecture partitioning is used to simplify the development and management of the Enterprise Architecture, by reducing complexity, improving governance, enhancing reusability, and increasing alignment and agility12. Therefore, the statement that partitions are used to simplify the management of the Enterprise Architecture is correct.
The other statements are incorrect because:
• Partitions are not equivalent to architecture levels. Architecture levels are different layers of abstraction that describe the Enterprise Architecture from different perspectives, such as strategic, segment, and capability3. Partitions are subsets of architectures that are defined within or across the levels, based on specific criteria1.
• Partitions do not necessarily reflect the organization’s structure. The organization’s structure is one possible criterion for partitioning the architecture, but it is not the only one. Other criteria, such as business function, product, service, geography, etc., can also be used to partition the architecture12.
• Partitions are not defined and assigned to agile Enterprise Architecture teams. Agile Enterprise Architecture is an approach that applies agile principles and practices to the architecture work, such as iterative development, frequent feedback, adaptive planning, and continuous delivery4. Partitions are not a specific feature of agile Enterprise Architecture, but a general technique that can be applied to any architecture method or framework, including TOGAF12.

Question #3
Which of the following best describes purpose of the Business Scenarios?
- A . To identify risk when implementing an architecture project
- B . To identify and understand requirements
- C . To catch errors in a project architecture early
- D . To guide decision making throughout the enterprise
Correct Answer: B
B
Explanation:
Business scenarios are a technique for capturing, clarifying, and communicating the functional and non-functional requirements of a system. Business scenarios describe the business environment, the actors involved, the desired outcomes, and the processes or rules that govern the behavior of the system. Business scenarios are useful for ensuring that the architecture addresses the real needs and concerns of the stakeholders, and for validating and testing the architecture against expected situations. Business scenarios are developed in Phase A: Architecture Vision of the ADM cycle, and refined and updated throughout the other phases3

Question #5
Complete the sentence. The key purpose of Gap Analysis is to _____
- A . establish quality parameters for the architecture
- B . identify potential missing or overlapping functions
- C . validate nonfunctional requirements
- D . identify commercial building blocks to be purchased
- E . determine the required service levels for the architecture
Correct Answer: B
B
Explanation:
Gap Analysis is a technique that compares the Baseline Architecture and the Target Architecture to identify the differences and gaps between them. The purpose of this technique is to determine the changes and additions that are required to achieve the desired future state of the architecture. One of the main aspects of Gap Analysis is to identify the functions that are missing or overlapping in the current and future architectures, and to plan how to address them. This helps to ensure that the architecture is complete, consistent, and aligned with the business objectives and requirements3

Question #6
Which of the following best describes the need for the ADM process to be governed?
- A . To enable development of reference architectures
- B . To verify that the method is being applied correctly
- C . To enable a fast response to market changes
- D . To permit the architecture domains to be integrated
Correct Answer: B
B
Explanation:
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

Question #7
Consider the image showing basic architectural concepts.
What are items A and B?
- A . A-Architecture Viewpoint, B-Architecture View
- B . A-Architecture Board, B-Architecture Capability
- C . A-Candidate Architecture, B-Trade-off
- D . A-Requirement. B-Candidate Architecture
Correct Answer: A
A
Explanation:
The image shows a diagram that illustrates the basic concepts of architecture description as defined by the ISO/IEC/IEEE 42010:2011 standard1, which is also adopted by the TOGAF standard2.
According to the ISO/IEC/IEEE 42010:2011 standard, an architecture description is a work product used to express an architecture, and it consists of one or more architecture views1.
An architecture view is a representation of a system from the perspective of a related set of concerns, and it conforms to an architecture viewpoint1.
An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1.
Therefore, the correct answer is option A, which identifies the items labeled as “A” and “B” in the image as an architecture viewpoint and an architecture view, respectively.

Question #8
Complete the sentence The Enterprise Continuum provides methods for classifying architecture artifacts as they evolve from________________________.
- A . Solutions Architectures to Solution Building Blocks
- B . generic architectures to reusable Solution Building Blocks
- C . Foundation Architectures to re-usable architecture assets
- D . generic architectures to Organization-Specific Architectures
Correct Answer: D
D
Explanation:
The Enterprise Continuum provides methods for classifying architecture artifacts as they evolve from generic architectures to Organization-Specific Architectures. Generic architectures are architectures that have been developed for use across a wide range of enterprises with similar characteristics. They provide common models, functions, and services that can be reused and adapted for specific purposes. Organization-Specific Architectures are architectures that have been tailored to meet the needs and requirements of a particular enterprise or a major organizational unit within an enterprise. They reflect the unique vision, goals, culture, structure, processes, systems, and technologies of that enterprise or unit.
