- A
Bedrock Knowledge Bases with grounding
Why wrong: Grounding ensures responses are based on documents, but does not filter PII.
- B
Bedrock Guardrails with content filtering
Why wrong: Content filtering addresses toxicity, not PII.
- C
Bedrock Guardrails with topic denial
Why wrong: Topic denial blocks topics, not PII.
- D
Bedrock Guardrails with PII detection
Guardrails can detect and redact PII from model responses.
- E
Bedrock Agent with a Lambda function to post-process responses
A Lambda can be used as a custom post-processing step to remove PII before returning the response.

This AIF-C01 practice question tests your understanding of aif-c01 exam topics. 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 corporation needs to deploy a chatbot that must not output any personally identifiable information (PII) such as credit card numbers or social security numbers. Which TWO Bedrock features should they use together to achieve this? (Select TWO.)
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
✓
Bedrock Guardrails with PII detection
Option D is correct because Bedrock Guardrails includes a dedicated PII detection feature that can identify and redact sensitive information like credit card numbers and social security numbers from model outputs. Option E is correct because a Bedrock Agent with a Lambda function can post-process responses to scan for and remove any PII that might have been missed by the guardrails, providing an additional layer of defense.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the distinction between content filtering (harmful content) and PII detection (sensitive data), leading candidates to mistakenly select content filtering when the requirement is specifically about preventing PII leakage.
Detailed technical explanation
How to think about this question
Bedrock Guardrails' PII detection uses regex patterns and machine learning models to identify entities such as SSNs (e.g., ###-##-####), credit card numbers (Luhn algorithm validation), and phone numbers. The Lambda function in a Bedrock Agent can implement custom logic, such as calling AWS Comprehend's PII detection API or using a custom regex library, to scrub any residual PII before the response reaches the user.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
