AIF-C01 Applications of Foundation Models Practice Question
A startup is using Amazon Bedrock to power a virtual assistant. They need to ensure that personally identifiable information (PII) is not included in the model's responses. Which feature should they enable?
⚠ Common exam trap
Many candidates confuse data protection features like encryption or logging with content filtering, not realizing that PII redaction is a specific guardrail policy that actively modifies model outputs in real time.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable PII redaction in the Bedrock guardrails.
Amazon Bedrock Guardrails provide a configurable content filtering and PII redaction feature that can automatically detect and mask personally identifiable information (PII) in model inputs and outputs. By enabling PII redaction within guardrails, the startup can ensure that sensitive data like names, addresses, or credit card numbers are removed or obfuscated before the virtual assistant's responses reach the user. This is the direct and intended mechanism for preventing PII leakage in model responses.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable PII redaction in the Bedrock guardrails.
Why this is correct
Guardrails can redact PII from prompts and completions.
- ✗
Enable model invocation logging.
Why it's wrong here
Logging captures data but does not prevent PII from being output.
- ✗
Configure a VPC endpoint.
Why it's wrong here
VPC endpoints control network traffic, not content.
- ✗
Enable data encryption at rest.
Why it's wrong here
Encryption protects data but does not filter PII from responses.
