AI0-001 AI Implementation and Operations Practice Question
A company uses a large language model (LLM) to generate customer support responses. They notice the model sometimes produces harmful outputs. Which implementation strategy best reduces this risk while maintaining performance?
⚠ Common exam trap
CompTIA often tests the misconception that simple output filtering or prompt engineering is sufficient for safety, when in fact only training-based alignment methods like RLHF can meaningfully change model behavior without sacrificing performance.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Fine-tune the model using reinforcement learning from human feedback
Reinforcement learning from human feedback (RLHF) directly trains the model to align its outputs with human preferences for safety and helpfulness, reducing harmful outputs while preserving performance. Unlike superficial filters or prompts, RLHF adjusts the model's internal behavior through reward modeling and policy optimization, making it the most effective strategy for sustained safety improvements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Implement a keyword-based output filter
Why it's wrong here
Filters can be bypassed and may over-block.
- ✗
Use a smaller, less capable model
Why it's wrong here
Smaller models may still produce harmful outputs and have lower quality.
- ✗
Add system prompts instructing the model to be safe
Why it's wrong here
Prompting alone is often insufficient for alignment.
- ✓
Fine-tune the model using reinforcement learning from human feedback
Why this is correct
RLHF effectively aligns model outputs with human preferences.
