The answer is Constitutional AI and Reinforcement Learning from Human Feedback (RLHF). Constitutional AI embeds a predefined set of ethical principles directly into the model’s training process, enabling it to self-critique and revise outputs to avoid harmful or unsafe medical advice, which is critical for safety reliability medical generative AI. RLHF further refines this by using human evaluators to rank responses, teaching the model to prioritize helpfulness and harmlessness in high-stakes contexts. On the Google Cloud Generative AI Leader exam, this question tests your understanding of how to align LLMs with domain-specific safety constraints, often appearing as a scenario where you must choose techniques that reduce hallucination and bias without sacrificing clinical accuracy. A common trap is selecting only one technique or confusing RLHF with simple supervised fine-tuning. Memory tip: think of Constitutional AI as the “rulebook” and RLHF as the “human referee” working together to keep medical advice safe.
Generative AI Leader Practice Question: Techniques to Improve Generative AI Model Output
This Generative AI Leader practice question tests your understanding of techniques to improve generative ai model output. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A team is fine-tuning a large language model for medical advice. Which TWO techniques are most effective for improving the safety and reliability of the model's outputs?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Constitutional AI
Constitutional AI (A) is correct because it embeds a set of ethical principles directly into the model's training process, allowing the model to self-critique and revise its outputs to avoid harmful or unsafe medical advice. This technique proactively enforces safety constraints without requiring extensive human labeling, making it highly effective for high-stakes domains like healthcare.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Constitutional AI
Why this is correct
Constitutional AI uses predefined rules to guide model behavior.

✗
Lowering the temperature to 0.0
Why it's wrong here
Low temperature reduces creativity but doesn't ensure safety.
✗
Increasing training data size
Why it's wrong here
More data may not improve safety.
✗
Increasing top_p to 1.0
Why it's wrong here
High top_p increases randomness, which can harm reliability.
✓
Reinforcement learning from human feedback (RLHF)
Why this is correct
RLHF aligns model with human preferences for safety.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that hyperparameter tuning (temperature, top_p) or data scaling alone can solve safety issues, when in fact alignment techniques like Constitutional AI and RLHF are specifically designed for that purpose.
Detailed technical explanation
How to think about this question
Constitutional AI works by first training a model to generate harmful outputs, then using a set of written rules (the 'constitution') to have the model critique and revise its own responses, creating a preference dataset for fine-tuning. RLHF (E) complements this by using human feedback to train a reward model that scores outputs, then optimizing the LLM via Proximal Policy Optimization (PPO) to align with human preferences—together, these two techniques form a robust safety alignment pipeline for sensitive domains like medical advice.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
