CEA - Certified Enterprise Architect Architecture Viewpoints and Views Questions and Answers

Question 1

An enterprise architect is preparing documentation for a new system. To ensure all relevant parties can understand the architecture, the architect plans to create several diagrams, including a logical view for developers, a deployment view for infrastructure teams, and a process view for system engineers. According to ISO/IEC/IEEE 42010, what is the architect defining by specifying the conventions, model kinds, and languages for creating these specific views?

Accepted Answer

Architecture Viewpoints

Answer

An Architecture Viewpoint establishes the conventions for constructing and using a view. It acts as a template or set of rules that defines the stakeholders, their concerns, and the languages, notations, and model kinds to be used in creating a specific type of view. The architect in the scenario is defining the 'how-to' for creating views, which is the role of a viewpoint.

Question 2

A financial services company is undergoing a digital transformation. The Chief Technology Officer (CTO) is concerned about the scalability and security of the proposed architecture. The business analysts are focused on ensuring the new system supports all required business processes. According to TOGAF and general enterprise architecture principles, what is the primary mechanism for addressing these distinct stakeholder interests?

Accepted Answer

Creating specific Architecture Views tailored to each stakeholder group's concerns.

Answer

Architecture Views are created to address the specific concerns of different stakeholders. A view is a representation of the system from the perspective of a related set of concerns. For the CTO, a view focusing on technical and security aspects would be appropriate, while for business analysts, a business process-oriented view would be created. This separation ensures communication is effective and relevant to the audience.

Question 3

Which of the following statements best describes the relationship between an architecture view and an architecture viewpoint?

Accepted Answer

A viewpoint is a specification for the creation of a view; a view is an instance that conforms to a viewpoint.

Answer

The relationship is often described with the analogy: 'a view is to a viewpoint as a program is to a programming language'. A viewpoint defines the rules, conventions, and language (the perspective), while the view is the actual representation of a specific architecture created according to those rules. Therefore, a viewpoint is the specification or template, and the view is the resulting artifact.

Question 4

An architect is tasked with documenting the architecture of a large, distributed system. The organization has a mature architecture practice and maintains a library of predefined templates for creating different types of architectural diagrams, specifying the notations, stakeholders to be addressed, and concerns to be covered. What is the primary benefit of this practice?

Accepted Answer

It promotes consistency and reusability, reducing the effort required for architects.

Answer

By maintaining a library of predefined viewpoints (templates), an organization can ensure that architectures are described consistently across different projects. This promotes reusability, as viewpoints can be applied to multiple systems. It reduces the workload for architects who don't have to 'reinvent the wheel' for each new project and improves comprehensibility for stakeholders who become familiar with the standard viewpoints.

Question 5

In the context of the ISO/IEC/IEEE 42010 standard, which element is defined as 'any interest in the system' held by stakeholders, which ultimately determines the selection of appropriate viewpoints?

Accepted Answer

A Concern

Answer

ISO/IEC/IEEE 42010 explicitly defines a 'Concern' as any interest in a system, such as functionality, cost, security, or performance. The entire purpose of creating different views and viewpoints is to frame these concerns so they can be effectively addressed for the relevant stakeholders.
