iSAQB Certified Professional for Software Architecture – Foundation Level (CPSA-F) — Question 36

You want to demonstrate to colleagues that certain building blocks are suitable for the implementation of a use-case scenario.
Which of the following UML diagrams is best suited for this?

Answer options

• A. Use-case diagram
• B. Sequence diagram
• C. Activity diagram
• D. Class diagram

Correct answer: A

Explanation

The Use-case diagram is specifically designed to illustrate the interactions between users and systems in a use-case scenario, making it the best choice. The Sequence diagram focuses on the order of messages exchanged, the Activity diagram represents workflows, and the Class diagram outlines the structure of classes, none of which directly demonstrate suitability for a use-case.
