Amazon Web Services Updated AIF-C01 Exam Questions and Answers by emile

The correct answer is D. Amazon Bedrock Agents are used to orchestrate and execute complex workflows by connecting foundation models with APIs, databases, and tools. According to AWS documentation, agents interpret user inputs, plan the necessary steps, call external APIs or systems, and return structured results. This allows the model to go beyond text generation into full automation workflows—such as booking tasks, querying internal systems, or summarizing reports. Option A describes multi-modal models, B refers to prompt tuning, and C misstates control delegation; agents act autonomously based on model reasoning. Thus, Bedrock Agents function as intelligent orchestrators, handling multi-step task execution through integrated tool use.

The correct answer is Amazon Bedrock, AWS’s fully managed service for building and scaling generative AI applications using foundation models (FMs). Bedrock gives developers access to models from leading providers such as Anthropic (Claude), Meta (Llama), Mistral, Cohere, and Amazon Titan. Users can invoke these models via API without managing infrastructure or model training. According to AWS documentation, Bedrock supports tasks such as text generation, summarization, question answering, image generation, and RAG workflows with minimal setup. It supports both on-demand and provisioned throughput modes and integrates with features like Guardrails, Knowledge Bases, and Agents for secure, enterprise-grade applications. Amazon Q Developer is a generative AI tool for developers, but it doesn’t host or scale models. Amazon Kendra is an intelligent search engine, and Amazon Comprehend is used for NLP tasks like entity extraction—not foundation model access.

The correct answer is B because Amazon Augmented AI (Amazon A2I) allows developers to integrate human review workflows into ML systems. It supports defining confidence thresholds, such that only low-confidence predictions are sent to human reviewers.

From AWS documentation:

" Amazon A2I provides built-in human review workflows for ML predictions. You can configure confidence thresholds to determine when human review is triggered, enabling continual adjustment based on accuracy needs. "

This supports use cases where business decisions (like financial approvals) require manual oversight for edge cases.

Explanation of other options:

A. Amazon Personalize is used for recommendation systems, not human review.

C. Amazon Inspector is for security assessment and vulnerability scanning.

D. AWS Audit Manager is used for compliance audits, not ML prediction reviews.

Amazon SageMaker is AWS’s fully managed ML service that supports retraining and deploying models with new, recent data for continuous improvement. This directly meets the requirement to iterate and continuously improve model accuracy.

A is correct:

" Amazon SageMaker enables teams to retrain models using the most recent data, ensuring ongoing improvement in model accuracy. "

B (Amazon Personalize) is for recommendations, not general ML or waste reduction.

C (CloudWatch) is for monitoring, not ML training or deployment.

D (Rekognition) is for image/video analysis.
