Case Study
Company Background: FinSecure is a mid-sized investment bank that has traditionally relied on a monolithic, on-premise core banking system. The company faces increasing competition from agile fintech startups and pressure from regulators to improve its risk management and reporting capabilities. To remain competitive and compliant, the board has mandated a move to a more modern, flexible, and scalable architecture.
Architectural Approach: The enterprise architecture team has decided to adopt a microservices-based architecture hosted on a public cloud platform. The transition will be managed as a series of distinct projects over two years. An Architecture Board has been established, and one of its first tasks is to define a set of Architecture Principles to guide this complex transformation. The CIO has emphasized that these principles must be robust and provide clear, unambiguous direction.
Principle Format: The team has decided to follow the recommended TOGAF format for principles, which includes a Name, Statement, Rationale, and Implications.
Question: The team proposes a principle named 'Cloud First'. Which of the following 'Implications' statements would be most effective and appropriate for this principle, according to TOGAF best practices?
Show answer details
Correct answer: C
According to TOGAF, the 'Implications' section should highlight the requirements, both for the business and IT, for carrying out the principle. This option is the most effective because it is specific, actionable, and defines the consequences of adherence and non-adherence. It sets clear expectations for project teams and establishes the governance process (exception request), making the principle enforceable.

What is the primary output of Phase F (Migration Planning) in the TOGAF ADM?
Show answer details
Correct answer: C
The main objective and deliverable of Phase F is the finalization of the detailed Implementation and Migration Plan. This plan coordinates a series of implementation projects and work packages into a cohesive roadmap that transitions the enterprise from the Baseline Architecture to the Target Architecture.

An architect is modeling the relationships between business processes and the applications that support them. Which type of TOGAF artifact would be most suitable for clearly representing this many-to-many relationship?
Show answer details
Correct answer: B
A Matrix is specifically designed to show the relationships between two or more types of entities. An application/process matrix, with processes on one axis and applications on the other, is a classic example used in enterprise architecture to clearly and concisely visualize which applications support which business processes.
- 4
In TOGAF, what term is used to describe the representation of an enterprise's architecture at a particular point in time?
Show answer details
Correct answer: C
The Architecture Landscape presents a view of the architecture at specific points in time. This includes the Baseline (current state), Target (future state), and any intermediate Transition Architectures. It provides a 'snapshot' of the assets in use across the enterprise.
- 5
An architecture team is populating its Architecture Repository. They are classifying assets to facilitate reuse. One asset is the 'NIST Cybersecurity Framework,' a widely accepted industry standard. Another is 'EnerVolt's Customer Billing System,' a specific application architecture deployed in their environment.
How would these two assets be classified within the Enterprise Continuum?

Correct answer: B
The Enterprise Continuum classifies assets from generic to specific. The NIST Cybersecurity Framework is a generic, fundamental standard applicable across many industries, making it a Foundation Architecture. 'EnerVolt's Customer Billing System' is a complete architecture tailored specifically for the EnerVolt organization, placing it at the most specific end of the Architecture Continuum as an Organization-Specific Architecture.

A global logistics company is in Phase B (Business Architecture) of an initiative to optimize its supply chain. The architects have identified a critical business capability, 'Real-time Parcel Tracking', which is currently supported by multiple, siloed legacy systems. To model the target state, what is the most appropriate TOGAF artifact to create first?
Show answer details
Correct answer: B
In Phase B, the primary focus is on the business architecture. A Business Capability Map is a fundamental artifact that provides a structured view of what the business does, independent of how it does it. This map is crucial for identifying redundancies, gaps, and areas for investment, such as the 'Real-time Parcel Tracking' capability, before defining any technical solutions.
- 7
An enterprise architecture team is establishing a new governance framework. They want to ensure that all new projects align with the target architecture and reuse existing assets where possible. Which TWO of the following mechanisms are essential for effective implementation governance as described in TOGAF Phase G? (Select TWO)
Show answer details
Correct answer: B, C
Architecture Contracts are a key output of Phase G. They specify the deliverables, quality, and conformance criteria for implementation projects, ensuring they adhere to the defined architecture.
Compliance assessments are a core activity in Phase G. They provide a formal check to ensure that the implementation project is developing a solution that is compliant with the architecture specification.

True or False: The Enterprise Continuum provides a method for classifying solution components, but it is not intended to be used for classifying architectural assets.
Show answer details
Correct answer: B
The statement is false. The Enterprise Continuum is composed of two parts: the Architecture Continuum and the Solutions Continuum. The Architecture Continuum is specifically designed to classify architectural assets (such as models, patterns, and descriptions) from generic to specific, while the Solutions Continuum classifies the corresponding implementation components.
- 9
During a review of the Architecture Repository, an architect discovers that it contains numerous industry-standard reference models for financial services (e.g., BIAN) and a set of organization-specific Architecture Building Blocks (ABBs) derived from past projects. According to the Enterprise Continuum, where do these assets respectively belong?
Show answer details
Correct answer: D
The Architecture Continuum classifies assets from generic to specific. Industry-standard models like BIAN fit into the 'Industry Architectures' category. Architecture Building Blocks created specifically for the organization's use, derived from its unique context and projects, are classified under 'Organization-Specific Architectures'.

A large manufacturing firm is customizing its architecture capability in the Preliminary Phase. The CIO insists that the architecture practice must directly support the company's strategic goals of 'Operational Excellence' and 'Product Innovation'. Which TOGAF concept should be defined in this phase to translate these strategic goals into actionable guidance for all future architecture work?
Show answer details
Correct answer: B
Architecture Principles are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in which an organization sets about fulfilling its mission. In the Preliminary Phase, these principles are established to align the architecture work with business strategies. For example, a principle like 'Maximize Process Automation' would directly support 'Operational Excellence'.
