Generative AI Leader Fundamentals of Generative AI Practice Question
A financial services company wants to use generative AI to generate personalized investment advice. They must ensure responses comply with regulatory requirements (e.g., no guarantees of returns). Which Vertex AI safety feature should they primarily use?
⚠ Common exam trap
Many candidates confuse grounding (factual retrieval) with compliance enforcement, or assume prompt engineering is sufficient for regulatory guardrails, when in fact only a deterministic blocklist can reliably prevent specific prohibited phrases from appearing in generated outputs.
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
✓
Safety filters with a custom blocklist that includes phrases like 'guaranteed return'.
Safety filters with a custom blocklist allow the company to define specific prohibited phrases (e.g., 'guaranteed return') that the model must avoid generating. This provides a deterministic, rule-based enforcement layer that directly addresses regulatory compliance by blocking disallowed content at inference time, without relying on the model's probabilistic behavior.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Vertex AI Grounding with their compliance database.
Why it's wrong here
Grounding improves accuracy but does not block specific phrases.
- ✗
Prompt engineering with instructions to avoid guarantees.
Why it's wrong here
Prompt engineering is not foolproof; safety filters are more robust.
- ✓
Safety filters with a custom blocklist that includes phrases like 'guaranteed return'.
Why this is correct
Safety filters can block defined categories or custom phrases.
- ✗
Reinforcement learning from human feedback (RLHF) on the model.
Why it's wrong here
RLHF is costly and not a real-time filter.
