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

The correct answer is AWS Artifact, which is a central resource for accessing AWS compliance documentation, audit reports, and certifications from both AWS and third-party providers, including ISVs. According to AWS documentation, Artifact supports notifications for newly available reports. Customers can subscribe to notification emails when specific compliance documents or updates are published. This feature is ideal for regulated industries or companies needing third-party verification of compliance and security postures. Artifact provides access to reports such as SOC 2, ISO, PCI, and more, and is commonly used for audit preparation and vendor risk management. In contrast, AWS Audit Manager helps create internal audit frameworks but is not focused on third-party report distribution. AWS Data Exchange is for marketplace data sharing, and Trusted Advisor provides performance and cost optimization recommendations, not compliance document alerts. Thus, AWS Artifact is the purpose-built service that meets this requirement.

The correct answer is B because Amazon Bedrock Prompt Management supports tool use via tools configuration, which enables a prompt to define tools that can invoke external APIs or services.

According to the AWS documentation:

"You can use the tools configuration in Amazon Bedrock to specify external APIs that a foundation model can call during inference. This enables the model to interact with external services, such as invoking functions, retrieving real-time data, or executing workflows."

The tools configuration allows a prompt to describe which external functions (APIs) are available, their parameters, and how they should be invoked, similar to OpenAI’s function calling or tool use pattern.

Creating an Amazon Bedrock knowledge base allows the integration of external or private data sources with a foundation model (FM) like Amazon Titan. This integration helps supplement the model with relevant data from the company's private data sources to enhance its responses.

Option C (Correct): "Create an Amazon Bedrock knowledge base": This is the correct answer as it enables the company to incorporate private data into the FM to improve its effectiveness.

Option A: "Use a different FM" is incorrect because it does not address the need to supplement the current model with private data.

Option B: "Choose a lower temperature value" is incorrect as it affects output randomness, not the integration of private data.

Option D: "Enable model invocation logging" is incorrect because logging does not help in supplementing the model with additional data.

Precision is the metric that measures the proportion of true positives (actual frauds) among all flagged positives (flagged frauds). High precision ensures that most of the flagged cases are truly fraudulent, minimizing the number of false positives employees must review.

C is correct:

"Precision is the ratio of true positives to all predicted positives, and it answers: ‘Of all the cases flagged as fraud, how many were actually fraud?’ High precision means fewer non-fraudulent cases are sent for manual review."

(Reference: AWS ML Concepts – Precision and Recall, AWS Certified AI Practitioner Study Guide)

A (Recall) measures how many actual frauds are caught, but does not minimize false positives.

B (Accuracy) can be misleading in imbalanced datasets (like fraud detection).
