Try 3 AI Practitioner (AIF-C01) practice questions
Choose an answer, explore the explanation, and see why the other options are less suitable. Three short scenarios. No sign-in required.
1. Predicting a numeric sales value
A retailer has historical data containing product price, promotions, seasonality, and units sold. The company wants an ML model to predict the number of units a product will sell next month. Which ML technique is most appropriate?
Answer and full explanation
Correct answer: B — Regression.
Why B is correct
Regression is used when the prediction target is a numeric value. In this scenario, the retailer wants to predict how many units will be sold, so the model output is a number rather than a category. AIF-C01 Task Statement 1.2 explicitly requires candidates to select suitable AI/ML techniques such as regression, classification, and clustering for business use cases. AWS machine learning documentation likewise describes regression as the approach for predicting numeric targets, including examples such as the number of units a product will sell. Regression therefore best fits the requirement.
Why the other options are less suitable
- A — Clustering: Clustering groups similar observations without predicting a specific labeled numeric target. It could segment products or customers, but it does not directly answer how many units will sell next month.
- C — Binary classification: Binary classification predicts one of two categories, such as whether sales will exceed a threshold. The business needs the actual numeric sales estimate rather than a yes-or-no outcome.
- D — Natural language processing: NLP focuses on understanding or generating human language. The inputs in this scenario are structured business variables used to predict a numeric sales quantity.
Key takeaway: When the target to predict is a continuous or numeric value, regression is the appropriate ML problem type.

2. Grounding an assistant in changing company documents
A company wants a generative AI assistant to answer employee questions from internal policy documents that change frequently. The company wants responses grounded in the latest approved information without retraining the foundation model for every document update. Which approach best meets the requirement?
Answer and full explanation
Correct answer: C — Use Retrieval Augmented Generation with an Amazon Bedrock Knowledge Base.
Why C is correct
Retrieval Augmented Generation (RAG) retrieves relevant information from an external data source and adds it to the context used by a foundation model. The decisive requirement is that the company's policies change frequently and should be reflected without repeatedly retraining the model. AIF-C01 Task Statement 3.1 explicitly includes RAG and Amazon Bedrock Knowledge Bases as design considerations for applications that use foundation models. AWS documentation states that Bedrock Knowledge Bases can retrieve proprietary information and use it to improve the relevance and accuracy of generated responses. RAG therefore provides a better fit than repeatedly changing the underlying model.
Why the other options are less suitable
- A — Increase temperature: Temperature affects response variability rather than supplying current authoritative business information. It would not make the assistant reliably use the latest policy documents.
- B — Fine-tune after every update: Fine-tuning can customize model behavior, but retraining whenever policies change adds unnecessary operational effort. RAG is better suited to frequently changing reference knowledge.
- D — Rely only on pretraining: A general foundation model does not automatically contain private or newly revised company policies. Removing the internal source would weaken grounding and freshness.
Key takeaway: RAG is useful when generated answers must incorporate current proprietary knowledge without retraining the foundation model for every content change.
3. Filtering prompt attacks in a generative AI application
A company is building an Amazon Bedrock chatbot. Security testing shows that users may submit prompts that try to override developer instructions or extract restricted content. Which AWS feature is specifically intended to help detect and filter these prompt attacks?
Answer and full explanation
Correct answer: A — Amazon Bedrock Guardrails.
Why A is correct
Amazon Bedrock Guardrails provides configurable safeguards for generative AI applications and can evaluate both user inputs and model responses. AIF-C01 Task Statement 5.1 specifically includes Amazon Bedrock Guardrails, prompt injection, output filtering, and validation among security concepts. AWS documents prompt-attack filtering for jailbreaks, prompt injection, and prompt leakage, including attempts to override developer instructions. Guardrails can be configured to detect or block these inputs according to application requirements. This makes Bedrock Guardrails the feature that directly addresses the scenario.
Why the other options are less suitable
- B — AWS Cost Explorer: Cost Explorer is used to analyze AWS cost and usage data. It does not inspect prompts or apply generative AI safety controls.
- C — Amazon S3 Lifecycle: S3 Lifecycle manages transitions and expiration of objects stored in Amazon S3. It does not provide prompt-attack detection or model-response filtering.
- D — AWS Auto Scaling: Auto Scaling adjusts resource capacity according to demand. It addresses scalability and availability concerns rather than malicious or unsafe prompt content.
Key takeaway: Use Amazon Bedrock Guardrails when a generative AI application needs configurable protections such as prompt-attack, harmful-content, or sensitive-information filtering.

Requirements
- AWS describes the target candidate as having up to six months of exposure to AI/ML technologies on AWS, using but not necessarily building AI/ML solutions; this is recommended background rather than a mandatory prerequisite.
- If some concepts are unfamiliar, combine question practice with foundational study and your own exploration of AI use cases, GenAI, foundation models, prompting, RAG, model evaluation, responsible AI, and security controls.
- You will need an internet-connected device, a current web browser, and an ExamsDigest account to use the online practice product; this does not imply offline availability or a separate mobile application.

These details describe AWS’s official AI Practitioner (AIF-C01) exam.
What our students say
“The AIF-C01 practice exams helped me understand where I was weak, especially around foundation models, RAG, and responsible AI. The explanations were clear and made it easier to understand why the other answer choices were not the best fit.”
Cameron Pierce
✓ Verified Review
“The questions covered a good mix of AI fundamentals, generative AI, Amazon Bedrock, model evaluation, and security. Reviewing the questions I missed helped me focus my study time on the topics that needed more attention.”
Emily Rothman
✓ Verified Review
“I had already used AWS Skill Builder and other AI Practitioner study materials before trying ExamsDigest. What stood out was how clearly the explanations connected the AWS services to real use cases instead of just giving the correct answer.”

Your questions, answered.
Which AWS AI Practitioner exam do these practice questions target?
These questions target AWS Certified AI Practitioner AIF-C01, the exam currently shown on AWS’s certification and exam-guide pages. Before purchasing or taking the official exam, compare the AIF-C01 code with your scheduled test because AWS periodically updates certification guides and objectives. The current exam guide is Version 1.1, and AWS states that guide updates can be published before they begin appearing on the exam.
Who is AIF-C01 practice intended for?
It is intended for people building foundational AI, ML, generative AI, and AWS AI-services knowledge. AWS describes the target candidate as having up to six months of exposure to AI/ML technologies on AWS and using, but not necessarily building, AI/ML solutions. Developing models, feature engineering, hyperparameter tuning, building ML pipelines, advanced statistical analysis, and implementing governance frameworks are specifically outside the expected target-candidate scope.
How should I combine AI Practitioner practice with study?
Use practice questions alongside the official AIF-C01 guide and review why each technology fits a use case. Focus on regression and classification, GenAI terminology, Amazon Bedrock, SageMaker AI, prompting, RAG, model evaluation, responsible AI, IAM, encryption, Guardrails, and governance. The certification emphasizes foundational understanding and practical business applications rather than coding models or implementing production ML infrastructure, so concentrate on recognizing concepts, services, risks, and appropriate choices.
What should I do when I answer an AIF-C01 question incorrectly?
Use the explanation to identify the exact concept you confused, then return to the matching task statement before trying another scenario. For example, determine whether you selected the wrong ML problem type, confused fine-tuning with RAG, or overlooked a responsible-AI or security control. Reapply the concept to a different business situation rather than memorizing an answer letter. A practice percentage can identify gaps, but it should not be treated as a guaranteed official-exam outcome.
What question formats appear on the official AIF-C01 exam?
AWS’s current guide includes multiple-choice, multiple-response, ordering, and matching questions. It also specifies 50 scored questions and 15 unscored questions, with the unscored items not identified to candidates. These three preview examples use only single-answer multiple-choice because that is the interaction supported by this widget, so they do not recreate ordering, matching, or multiple-response tasks or establish what additional formats the paid ExamsDigest pack contains.
Does completing this practice earn AWS Certified AI Practitioner?
No. Completing an ExamsDigest practice product does not award AWS Certified AI Practitioner or replace AWS’s official certification process. Practice access, scheduling AIF-C01, taking the examination through AWS’s authorized testing options, and receiving the credential are separate activities. AWS currently provides an active scheduling option for AIF-C01 and states that the certification is valid for three years once earned through the official examination process.
30-day conditional refund policy
Eligible requests must be made within 30 calendar days, with no more than 20% of any included simulator completed. The purchase must not already be refunded or under a payment dispute or chargeback. Other provisions apply; mandatory consumer rights remain unaffected.
