Exam AWS Certified AI Practitioner AIF-C01 topic 1 question 50 discussion

Initially I was going with D but after reading this article sticking with A https://docs.aws.amazon.com/bedrock/latest/userguide/model-customization-use.html?form=MG0AV3

A To customize model you must purchase Provisioned Throughput.

D. Grant access to the custom model in Amazon Bedrock: When using Amazon Bedrock, you can fine-tune models or create custom versions of base models. To use your custom model, you would need to grant access to it within the Amazon Bedrock environment, enabling the model to be accessed and invoked by your application for summarization tasks.

Provisioned Throughput helps to improve the quality.

Accordingly to https://docs.aws.amazon.com/bedrock/latest/userguide/model-customization-use.html?form=MG0AV3

A particularly insightful comment from user "may2021_r" clarifies this: "Bottom Line: Required to use a custom model? Give Bedrock permissions and register your model so it can retrieve your artifacts. Optional but recommended at scale? Purchase Provisioned Throughput to guarantee a certain level of concurrency and avoid throttling." The key distinction is: Granting access is the fundamental requirement to use the model at all Provisioned Throughput is about performance and scaling, not basic access

D: Grant access to the custom model in Amazon Bedrock. Explanation: When a company trains a custom model to improve the performance of a base model provided by Amazon Bedrock, they need to ensure the custom model is accessible through the Amazon Bedrock service. Granting access to the custom model ensures it can be integrated and used through Bedrock's APIs and workflows for inference tasks like document summarization.

The correct answer is D. Access must be granted in Bedrock to use custom models.

To use the custom model with Amazon Bedrock, you need to grant access to the model first.

When a company has trained a custom model to improve the functionality of an Amazon Bedrock base model, they need to explicitly grant access to that custom model within the Bedrock environment. This allows Bedrock to utilize the custom model's capabilities for the desired use case. Why option A is incorrect: While purchasing provisioned throughput can improve the performance and responsiveness of a model in SageMaker, it's not necessary to use a custom model with Bedrock. Bedrock itself handles the infrastructure and resource allocation. Access granting is the key step for integration.

The correct answer is D: Grant access to the custom model in Amazon Bedrock. Why not B (Purchase Provisioned Throughput): 1. Provisioned Throughput is about performance and capacity, not access 2. Granting access is a mandatory first step for using custom models in Bedrock 3. Without proper access permissions, the model cannot be used at all, even with Provisioned Throughput Granting access (C) is essential because it: - Enables model visibility in Bedrock - Controls who can use the custom model - Is a prerequisite for any model operations

A. Purchase Provisioned Throughput for the custom model Provisioned Throughput is not relevant to Amazon Bedrock or custom models. It is generally associated with services like DynamoDB for performance scaling. C. Register the model with the Amazon SageMaker Model Registry While the Model Registry helps manage and track model versions, registering the model alone does not make it usable for inference. The model must still be deployed to a SageMaker endpoint. D. Grant access to the custom model in Amazon Bedrock Amazon Bedrock only provides access to foundation models hosted and managed by AWS. Custom models trained by the company need to be deployed separately via Amazon SageMaker.

A - is the right answer, as you NEED to Purchase Provisioned Throughput for customized model: https://docs.aws.amazon.com/bedrock/latest/userguide/model-customization-use.html D - is NOT (less) correct as IAM is OPTIONAL: https://docs.aws.amazon.com/bedrock/latest/userguide/model-customization-prereq.html

The correct answer is D. Grant access to the custom model in Amazon Bedrock.

B, and C, CANNOT be as the question is clear: "..using an Amazon Bedrock.. through Amazon BedRock" , in short SageMaker is out of the picture in this case. we are talking about a customize Bedrock Model.. so .. A is the only possible answer, we are not deploying a custom model in bedrock, we are using a bedrock customised model.. and in that case you have to pay the premium... as per this link: https://docs.aws.amazon.com/bedrock/latest/userguide/prov-throughput.html ...If you customized a model, you must purchase Provisioned Throughput to be able to use it

The question specifically mentions using the custom model "through Amazon Bedrock," which implies that the model should be integrated with Bedrock's infrastructure.
