Exam Certified Business Analyst topic 1 question 9 discussion

User acceptance testing (UAT) aims to validate that the system meets the business requirements and satisfies the needs of end-users, including various personas. If there was a major gap identified for one of the personas during UAT, it suggests that their requirements were not adequately captured or understood during the requirements gathering process. This failure could occur if key stakeholders, including representatives of all personas, were not included or consulted during requirements gathering. Incomplete or inaccurate requirements documentation can lead to gaps in the implemented solution, which may only be discovered during UAT. Therefore, failure to include all stakeholders in the requirements gathering process is the most likely reason for the identified gap.

Personas in SF more often mean a group of Users https://trailhead.salesforce.com/content/learn/modules/ux-personas-for-salesforce/get_started_with_personas So if there is a major gap for personas this means at some stakeholders were missing during discovery/req gathering A is the answer

scenario is documented so requirement gathering was good but then validation against the FR failed

A. Personas are based on a group of people - if the correct people were not present in discovery then we would not have been able to identify this persona.

A and not C, because user acceptance testing happens after the QA testing.

C is correct

C seems correct to me
