Pass the Amazon Web Services AWS Certified AI Practitioner AIF-C01 Questions and answers with CertsForce

The scenario where a student copies content from generative AI to write essays represents the challenge of plagiarism in responsible AI use.

Plagiarism:

Occurs when someone uses content generated by AI (or any source) without proper attribution, claiming it as their own.

This is a key challenge with generative AI models, which can produce human-like text that might be misused for academic or other purposes.

Why Option C is Correct:

Represents Unauthorized Use: Copying content directly from AI without attribution is a clear case of plagiarism.

Ethical Concern: Highlights the ethical considerations around using AI-generated content responsibly.

Why Other Options are Incorrect:

A. Toxicity: Refers to harmful or offensive content generation, not content copying.

B. Hallucinations: When AI generates incorrect or nonsensical information, not plagiarism.

D. Privacy: Involves the misuse or exposure of personal information, not copying content.

The correct answer is C because Amazon Nova Reel is the AWS foundation model designed for generative video use cases, providing end-to-end video generation using generative AI, which significantly reduces video creation time and eliminates the need for manual assembly.

According to AWS Bedrock documentation:

"Amazon Nova Reel enables users to generate short-form video content directly from prompts, including the ability to define style, motion, scenes, and transitions — streamlining the generative content creation process."

This is the most operationally efficient choice as it does not require stitching together images or using external editing tools.

Explanation of other options:

A and B involve generating intermediate images and then manually creating videos using video editing tools — not operationally efficient.

D. Amazon Nova Pro is intended for high-end professional-grade image or 3D content generation, but not specifically optimized for video generation like Nova Reel.

The correct answer is Text embeddings model, which transforms input text into dense vector representations. These vectors preserve semantic meaning and are ideal for similarity search, retrieval-augmented generation (RAG), and semantic search use cases, especially with Amazon OpenSearch Service. According to AWS Bedrock documentation, embeddings models are specifically designed to map text into a numerical space where related concepts are placed closer together. This allows efficient querying and ranking of documents based on the user’s question. This step is critical in chatbots using private knowledge bases. Text completion and instruction-following models focus on generating or following tasks, not producing embeddings. Image generation models are irrelevant here. Therefore, using a text embeddings model ensures that the chatbot retrieves contextually relevant results from stored vectors.

The correct answer is C because Amazon SageMaker JumpStart provides administrative controls that allow organizations to manage and restrict access to foundation models within the AWS environment.

According to the official AWS documentation:

"Amazon SageMaker JumpStart provides model access management capabilities that enable administrators to control which foundation models are visible and usable by end users. Using AWS Identity and Access Management (IAM) policies, you can restrict access to specific models or completely disable model discovery in JumpStart."

This allows companies to enforce governance over which FMs their users can see and interact with, satisfying the requirement to control employee access to publicly available foundation models.

Explanation of other options:

A. AWS Cost Explorer is used to analyze billing and usage data but does not control access to services or models. It is helpful for budgeting and visibility, not access control.

B. AWS Artifact provides access to compliance reports and certifications, not tools for controlling user access to ML models.

D. Amazon OpenSearch Service is used for search and analytics on structured and unstructured data. It does not provide access control mechanisms for foundation models.

AWS documentation defines prompt injection as a security and safety risk in which a user crafts input designed to override, manipulate, or bypass system-level instructions, safeguards, or intended model behavior. The example provided is a classic prompt injection attempt, where the user explicitly instructs the AI assistant to ignore prior rules and operate without restrictions.

In this scenario, the attacker is not exploiting training data or causing factual errors, but rather attempting to change the control flow and behavior of the AI system through malicious or manipulative prompts. AWS identifies prompt injection as a critical risk for generative AI systems, especially those exposed to end users through chat interfaces, APIs, or customer-facing applications.

The other options do not apply. Data bias relates to skewed or unfair training data. Hallucination refers to generating incorrect or fabricated information. Data exposure involves leaking sensitive or private data. None of these describe an attempt to override system instructions.

AWS recommends multiple mitigation strategies for prompt injection risks, including instruction hierarchy enforcement, prompt isolation, input validation, output filtering, and grounding responses using techniques such as Retrieval Augmented Generation. AWS also emphasizes the importance of clearly separating system instructions from user inputs to prevent unauthorized behavior changes.

Prompt injection is categorized by AWS as part of Responsible AI and security governance, highlighting the need for robust guardrails when deploying AI assistants in production. Therefore, the correct answer is prompt injection.
