Generative AI Leader Fundamentals of Generative AI Practice Question
A company is using Vertex AI to generate email responses. They want to ensure sensitive customer data (PII) is not included in the output. What is the most effective approach?
⚠ Common exam trap
A common mix-up: candidates assume a system prompt (Option A) is sufficient to control model behavior, but this exam tests the understanding that prompts are not enforceable guardrails, whereas safety filters are a hard technical control in Google Cloud.

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
✓
Configure safety filters to block PII categories.
Safety filters in Vertex AI are specifically designed to block categories of harmful content, including PII, at the model's output layer. This provides a deterministic, automated guardrail that prevents sensitive data from being generated, unlike prompt-based instructions which can be overridden by the model's training. Safety filters operate on the model's response before it is returned, ensuring PII is caught even if the model attempts to generate it.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a system prompt instructing the model to avoid PII.
Why it's wrong here
Prompt instructions are not always followed reliably.
- ✗
Fine-tune the model on a dataset that excludes PII.
Why it's wrong here
Fine-tuning does not guarantee PII filtering.
- ✗
Manually review each output before sending.
Why it's wrong here
Manual review is not scalable or real-time.
- ✓
Configure safety filters to block PII categories.
Why this is correct
Safety filters can automatically block PII.
