Question 3
Domain 3: Application DevelopmentA GenAI assistant answers confidently but cites no supporting internal source. What is the best design improvement?
Correct answer: D
Explanation
Requiring retrieved source grounding ties the answer to evidence instead of unsupported generation, which improves reliability and traceability. Showing the references used lets users verify the basis for the response and check whether the assistant relied on internal sources.
Why each option is right or wrong
A. Increase model temperature so answers are more creative
Higher temperature increases variability, not evidence-backed accuracy or traceable sourcing.
B. Remove citations to make the answer shorter
Removing citations hides provenance and makes verification harder, not better.
C. Add more unrelated documents to every prompt
Adding unrelated documents increases noise and can reduce retrieval relevance.
D. Require retrieved source grounding and show references used for the answer
The best improvement is to force the response to be generated from retrieved internal evidence and to expose the citations used, because the problem is not confidence but lack of verifiable support. In a retrieval-augmented design, the answer should be grounded in the retrieved documents and the UI should surface the source references so the user can audit what was actually used, rather than relying on an unsupported model output.
