1. A data scientist has developed a machine learning model that needs to be deployed in a container environment, and they want to use Amazon Elastic Container Service (ECS) to run the containers. Which of the following statements is true about using Amazon Elastic Container Registry (ECR) to store and manage the container images for this deployment?

A) ECR can be used to store the container images, and ECS provides built-in integration with ECR, allowing the data scientist to easily configure image permissions and authentication.
B) ECR is the only container registry that is compatible with Amazon ECS, and the data scientist must use ECR to store the container images.
C) The data scientist can use ECR to store the container images, but they need to manually configure IAM roles and permissions to allow ECS to pull images from ECR.
D) ECR is not required to use Amazon ECS, and the data scientist can store the container images in any container registry.



2. Which of the following statements is true about the Amazon Elastic Kubernetes Service (Amazon EKS)?

A) Amazon EKS is an open-source Kubernetes distribution that can be installed on any infrastructure.
B) Amazon EKS requires the user to manage the underlying infrastructure, including the Kubernetes control plane.
C) Amazon EKS provides a managed Kubernetes control plane that can be deployed across multiple AWS availability zones.
D) Amazon EKS only supports Kubernetes versions 1.16 and earlier.
E) Amazon EKS only works with Kubernetes clusters that are running on-premises.


3. You are responsible for managing a large AWS infrastructure and need to identify the root cause of a security incident that occurred several days ago. Which of the following statements about AWS CloudTrail is true?

A) AWS CloudTrail provides a chronological view of all API activity in your AWS account.
B) AWS CloudTrail does not provide details about the source IP address of API requests.
C) AWS CloudTrail only retains API logs for the last 24 hours.
D) AWS CloudTrail logs can only be accessed through the AWS Management Console.



4. You are working on a machine learning project that requires querying data from S3 using Amazon Athena. You want to optimize the performance of your queries by leveraging Amazon Athena's caching capabilities. Which of the following statements is true regarding caching in Amazon Athena?

A) Amazon Athena's caching capabilities can be used for any query results regardless of size.
B) Amazon Athena's caching capabilities require the use of a separate AWS service.
C) Amazon Athena's caching capabilities are limited to a maximum of 1GB of data.
D) Amazon Athena's caching capabilities can be disabled to reduce query latency.



5. Which of the following statements about Amazon SageMaker Notebooks is true?

A) SageMaker Notebooks are only available as a managed service within Amazon SageMaker Studio.
B) SageMaker Notebooks support only Python-based machine learning frameworks like TensorFlow and PyTorch.
C) SageMaker Notebooks can be accessed via a web-based interface or through a locally installed client.
D) SageMaker Notebooks can only be used to develop and train machine learning models on AWS.
