Passing an AWS certification requires more than just reading documentation; it requires applying concepts to scenario-based questions.When studying for this exam myself, I noticed a lack of realistic, high-quality practice questions that accurately reflect the difficulty and scope of the real test. That is exactly why I built this question bank. Every single question in this course has been written from scratch to mimic the real exam format, ensuring you encounter the same types of wording, distractors, and domain weightings. Furthermore, I have provided an in-depth explanation for every single option—both correct and incorrect—so you actually understand the "why" behind the technology, rather than just memorizing answers.Practice Questions PreviewBelow is a small sample of the types of questions you will find inside the course:Question 1: A financial institution wants to build a generative AI application to summarize lengthy compliance documents. They want to consume pre-trained foundation models via an API without managing any underlying server infrastructure. Which AWS service is the most appropriate choice?A. Amazon SageMakerB. Amazon EC2C. Amazon BedrockD. AWS LambdaE. Amazon ComprehendF. Amazon TextractCorrect Answer: COverall Explanation: Amazon Bedrock is a fully managed service that offers a choice of high-performing foundation models from leading AI companies via a single API, making it the perfect choice for building generative AI applications without managing infrastructure.Option A is incorrect: While Amazon SageMaker can host foundation models (via SageMaker JumpStart), it requires you to provision, manage, and scale the underlying infrastructure (endpoints), which goes against the requirement of not managing servers.Option B is incorrect: Amazon EC2 provides raw virtual servers. You would have to install, configure, and maintain the models and infrastructure entirely from scratch.Option C is correct: Amazon Bedrock is explicitly designed to provide serverless access to foundation models via API.Option D is incorrect: AWS Lambda is a serverless compute service. While it can trigger API calls, it is not an AI service that hosts foundation models.Option E is incorrect: Amazon Comprehend is an NLP service used for finding insights and relationships in text (like sentiment analysis), not a generative AI service for document summarization using foundation models.Option F is incorrect: Amazon Textract is an ML service used to extract text, handwriting, and data from scanned documents, not a generative AI summarization tool.Question 2: You are evaluating an ML model deployed in production to ensure it aligns with responsible AI guidelines. You notice the model's predictions disproportionately favor a specific demographic. Which concept of responsible AI does this issue primarily violate, and what should be used to document the model's intended use and characteristics?A. Transparency; implement Amazon CloudWatch logs.B. Privacy; implement AWS KMS encryption.C. Fairness; implement Model Cards.D. Robustness; implement Multi-AZ deployments.E. Explainability; implement AWS Config rules.F. Security; implement IAM resource policies.Correct Answer: COverall Explanation: Responsible AI dictates that models should treat all users fairly. When a model favors one demographic over another, it exhibits bias, which violates the principle of fairness. AWS recommends using Model Cards (like Amazon SageMaker Model Cards) to document a model's intended use, risk ratings, and training characteristics.Option A is incorrect: Transparency is important, but favoring a demographic is a bias issue, not strictly a logging/transparency issue. CloudWatch logs system metrics, not model intent.Option B is incorrect: Privacy and KMS encryption protect data from unauthorized access, but they do not solve demographic bias in predictions.Option C is correct: The scenario describes a fairness and bias issue. Model Cards are the AWS standard for documenting model governance, limitations, and fairness metrics.Option D is incorrect: Robustness in AI often refers to handling edge cases or adversarial inputs. Multi-AZ is for high availability of infrastructure, not model fairness.Option E is incorrect: Explainability is the ability to understand how a model makes a decision. While helpful, the core violation here is fairness. AWS Config tracks resource configuration changes, not AI explainability.Option F is incorrect: Security and IAM protect against unauthorized access, which is unrelated to demographic bias in the algorithm's outputs.Question 3: According to AWS security, compliance, and governance best practices, how should an organization ensure that only authorized applications can invoke generative AI models while keeping the prompt data strictly private?A. Assign AdministratorAccess to all applications to ensure seamless integration.B. Send prompt data over the public internet to third-party endpoints.C. Use IAM roles with least privilege and ensure data is encrypted at rest and in transit.D. Disable AWS CloudTrail to prevent prompt data from being logged or audited.E. Store all prompt data in an unencrypted Amazon S3 bucket for faster retrieval.F. Hardcode long-term IAM user credentials directly into the application's source code.Correct Answer: COverall Explanation: Security in AWS AI workloads relies on the principle of least privilege using IAM, combined with strong encryption protocols for data both at rest and in transit.Option A is incorrect: Providing broad AdministratorAccess violates the principle of least privilege and introduces massive security risks.Option B is incorrect: Sending private prompt data over the public internet without proper VPC endpoints (like AWS PrivateLink) compromises data privacy.Option C is correct: IAM roles grant specific, temporary permissions (least privilege), and encryption protects the privacy of the prompts.Option D is incorrect: AWS CloudTrail should be enabled for governance and auditing purposes. Disabling it reduces visibility and violates compliance frameworks.Option E is incorrect: Storing sensitive data in unencrypted S3 buckets directly violates privacy and compliance guidelines.Option F is incorrect: Hardcoding credentials is a severe security anti-pattern. IAM roles and temporary credentials should always be used for applications.Welcome to the Mock Exam Practice Tests Academy to help you prepare for your AWS Certified AI Practitioner.You can retake the exams as many times as you wantThis is a huge original question bankYou get support from me if you have questionsEach question has a detailed explanationMobile-compatible with the Udemy appI hope that by now you're convinced!
