Which statement best describes Architecture Description languages and viewpoints?

• A. A Architecture Evaluation methods
• B. B Architecture Description languages and viewpoints
• C. C System Testing approaches
• D. D Deployment strategies

Answer: (B)

The main idea being tested is that Architecture Description languages (ADLs) and viewpoints provide a structured way to describe and communicate a system’s architecture through multiple perspectives. An ADL offers a formal or semi-formal language for specifying architecture elements, their interfaces, and the relationships and constraints among them. A viewpoint defines a stakeholder-driven perspective—detailing what concerns to address and the notations or models used to represent those concerns for that group. Together, they form an architecture description framework that supports analysis, validation, and clear communication across stakeholders. This is the best description because it directly references both the language used to express architecture and the viewpoints that tailor representations to different concerns. The other options describe activities like evaluation, testing, or deployment, which are not about describing architecture with languages and viewpoints.
