Amazon Web Services AIF-C01 Dumps

To keep a foundation model (FM) relevant with the most recent data, the company needs a training strategy that supports regular updates. Continuous pre-training involves periodically updating a pre-trained model with new data to improve its performance and relevance over time, making it the best fit for this requirement.

Exact Extract from AWS AI Documents:

From the AWS AI Practitioner Learning Path:

"Continuous pre-training is a strategy where a pre-trained model is periodically updated with new data to keep it relevant and improve its performance. This approach is commonly used for foundation models to ensure they adapt to new trends and information."

(Source: AWS AI Practitioner Learning Path, Module on Model Training Strategies)

Detailed Explanation:

Option A: Batch learningBatch learning involves training a model on a fixed dataset in batches, but it does not inherently support regular updates with new data to keep the model relevant over time.

Option B: Continuous pre-trainingThis is the correct answer. Continuous pre-training updates the FM with recent data, ensuring it stays relevant by adapting to new trends and information.

Option C: Static trainingStatic training implies training a model once on a fixed dataset without updates, which does not meet the requirement for regular updates.

Option D: Latent trainingLatent training is not a standard term in AWS or ML contexts. It may refer to latent space in models like VAEs, but it is not a strategy for regular model updates.

A multi-modal embedding model is the correct type of foundation model (FM) for powering a search application that handles queries containing both text and images.

Multi-Modal Embedding Model:

Can process and integrate different types of data (e.g., text and images) into a common representation space, enabling a unified search capability.

Suitable for applications where queries or content involve multiple data modalities.

Why Option A is Correct:

Handles Multiple Modalities: Supports both text and image data, aligning with the application's requirement.

Improves Search Relevance: Allows for more accurate and relevant search results across different types of input data.

Why Other Options are Incorrect:

B. Text embedding model: Only handles text data, not images.

C. Multi-modal generation model: Focuses on generating outputs rather than embedding for search tasks.

D. Image generation model: Only handles image data, not suitable for text queries.

To comply with the company's security policy, which restricts each team to access data for only their own customers, creating an Amazon Bedrock custom service role for each team is the correct solution.

Custom Service Role Per Team:

A custom service role for each team ensures that the access control is granular, allowing only specific teams to access their own customer data in Amazon S3.

This setup aligns with the principle of least privilege, ensuring teams can only interact with data they are authorized to access.

Why Option A is Correct:

Access Control: Allows precise access permissions for each team's data.

Security Compliance: Directly meets the company's security policy requirements by ensuring data segregation.

Why Other Options are Incorrect:

B. Custom service role with customer name specification: This approach is impractical as it relies on manual input, which is prone to errors and does not inherently enforce data access controls.

C. Redacting personal data and updating S3 bucket policy: Redaction does not solve the requirement for team-specific access, and updating bucket policies is less granular than creating roles.

D. One Bedrock role with full S3 access and IAM roles for teams: This setup does not meet the least privilege principle, as having a single role with full access is contrary to the company's security policy.

Thus, A is the correct answer to meet the company's security requirements.
