Correct Answers: B, C and

Solution Architects can use various methods and templates for requirements collection and documentation. However, a requirement in high-level or any other requirements document should address the three main questions: who, what, and why: Who needs the requirement — means stakeholders (group or person) that ask for the requirement.
What does a customer need — does a requirement address the customer`s need.
Why customers interact with the system in the way they do — what is logic in the customer’s use of the system.
Solution Architect leads the requirements collection process. The best way to discuss the customers’ and users’ needs in the requirement capturing sessions. The goal of these sessions is to translate the needs into high-level requirements.
