Question 110 of 500
Applications of Foundation ModelshardMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to implement Retrieval-Augmented Generation (RAG) using a knowledge base on Amazon Bedrock combined with a system prompt demanding factual responses. This combination directly addresses the need to minimize hallucinations in a Bedrock healthcare chatbot by grounding the model’s output in verified, retrieved documents rather than relying solely on its parametric memory, while the system prompt enforces strict accuracy constraints for patient triage. On the AWS Certified AI Practitioner AIF-C01 exam, this question tests your understanding of how RAG and prompt engineering work together to improve factual reliability in regulated domains like healthcare—a common trap is assuming fine-tuning alone solves hallucinations, but it cannot guarantee grounding against incomplete data. Remember the memory tip: “RAG retrieves, prompt constrains” to recall that retrieval grounds the answer while the system prompt sets the safety guardrails.

AIF-C01 Applications of Foundation Models Practice Question

This AIF-C01 practice question tests your understanding of applications of foundation models. 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 healthcare company is deploying a conversational AI using a foundation model on Amazon Bedrock for patient triage. The application must minimize hallucinations and ensure factual accuracy. Which combination of techniques should the team implement?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "minimum / minimize"

    Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

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

Implement Retrieval-Augmented Generation (RAG) using a knowledge base on Amazon Bedrock and a system prompt demanding factual responses.

Option C is correct because RAG grounds responses in retrieved documents, and system prompts can enforce safety and accuracy constraints. Option A is wrong because fine-tuning alone may still lead to hallucinations if the training data is incomplete. Option B is wrong because RLHF is complex to implement on Bedrock and doesn't directly ground responses. Option D is wrong because reducing max tokens does not improve accuracy.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Implement Retrieval-Augmented Generation (RAG) using a knowledge base on Amazon Bedrock and a system prompt demanding factual responses.

    Why this is correct

    RAG retrieves relevant documents to ground the answer, and system prompts can enforce constraints, reducing hallucinations.

    Clue confirmation

    The clue word "minimum / minimize" in the question point toward this answer.

    Related concept

    Static NAT maps one inside address to one outside address.

  • Fine-tune the model on a large dataset of medical transcripts and deploy with default parameters.

    Why it's wrong here

    Fine-tuning alone does not guarantee factual accuracy; the model may still hallucinate on unseen topics.

  • Use reinforcement learning from human feedback (RLHF) on the deployed model.

    Why it's wrong here

    RLHF is not natively supported in Amazon Bedrock; it requires SageMaker and is complex to operationalize.

  • Set the maxTokens to a low value to force shorter, more focused answers.

    Why it's wrong here

    Limiting output length does not improve factual accuracy; the model may still generate incorrect information within the limit.

Common exam traps

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Trap categories for this question

  • Command / output trap

    Limiting output length does not improve factual accuracy; the model may still generate incorrect information within the limit.

Detailed technical explanation

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

  • Static NAT maps one inside address to one outside address.
  • PAT allows many inside hosts to share one public address using ports.
  • Inside local and inside global describe the private and translated addresses.
  • NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

  • Identify inside and outside interfaces first.
  • Check whether the scenario needs static NAT, dynamic NAT or PAT.
  • Do not confuse NAT matching ACLs with normal packet-filtering intent.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. 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 the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related AIF-C01 NAT questions on configuration and troubleshooting.
