NVIDIA Certified Professional – Accelerated AI Infrastructure — Question 4

Your deployed legal assistant shows great performance but occasionally repeats incorrect legal terms.
Which tuning method best improves factual reliability?

Answer options

• A. Replace retrieval with static hard-coded text snippets
• B. Use more verbose prompts to reinforce correct definitions
• C. Increase output randomness to improve exploration
• D. Add fact-checking steps using external tools during generation

Correct answer: D

Explanation

The correct answer is D because adding fact-checking steps with external tools helps verify the accuracy of the information provided, thereby improving the reliability of the legal terms. The other options either do not directly address accuracy (A, B, C) or could even lead to further inaccuracies by not verifying the content.
