- A
Bedrock Knowledge Bases
Why wrong: Knowledge Bases retrieve relevant content but do not deny off-topic queries; they simply return no matches.
- B
Bedrock Agents
Why wrong: Agents orchestrate multi-step tasks but do not have built-in topic denial capabilities.
- C
Bedrock Model Evaluation
Why wrong: Model evaluation is used for offline testing of model performance, not for runtime enforcement of content policies.
- D
Bedrock Guardrails
Guardrails can define denied topics and filter out queries that are unrelated to the document scope, ensuring the chatbot stays on-topic.

AIF-C01 Practice Question: A data scientist is building a RAG application…
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 data scientist is building a RAG application using Amazon Bedrock Knowledge Bases. The team requires that responses only use information from the uploaded documents and reject queries that are not related to the documents. Which Bedrock feature should be used to enforce this?
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
Bedrock Guardrails can deny topics outside the document scope. Knowledge Bases retrieves data but does not enforce content restrictions. Agents orchestrate actions but do not filter topics. Model evaluation is for testing, not runtime enforcement.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Why this is correct
Guardrails can define denied topics and filter out queries that are unrelated to the document scope, ensuring the chatbot stays on-topic.
Related concept
Standard ACLs match source addresses.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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. ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related AIF-C01 ACL questions on filtering logic and placement.
