Question #900 / 1019

A company wants to use Amazon Elastic Container Service (Amazon ECS) to deploy its application in a hybrid environment spanning on-premises infrastructure and the AWS Cloud. The application is containerized and requires a solution that can scale seamlessly across both environments. The company needs to maintain control over the underlying EC2 instances for their cloud-based containers and must implement a load balancer optimized for HTTP traffic.

Which combination of steps will meet these requirements? (Choose two.)

A

Configure an ECS cluster using AWS Fargate launch type for cloud containers and Amazon ECS Anywhere external launch type for on-premises containers.

B

Set up an Application Load Balancer to manage HTTP traffic for the cloud-based ECS services.

C

Deploy a Network Load Balancer to direct traffic to the ECS services running in the cloud.

D

Use AWS Fargate launch type for both cloud and on-premises containers within a single ECS cluster.

E

Create an ECS cluster with the Amazon EC2 launch type for cloud containers and Amazon ECS Anywhere with EC2 instances for on-premises containers.

Which combination of AWS services should a solutions architect propose to fulfill these requirements?

A

Amazon EBS for high I/O performance, Amazon S3 for the data lake, and Amazon S3 Glacier for compliance backups.

B

Amazon EC2 instance store for high I/O performance, Amazon EFS for the data lake, and Amazon S3 Glacier for compliance backups.

Sample Questions

Question #517 / 529

A company is developing a mobile backend using AWS. The backend uses Amazon API Gateway REST API to trigger an AWS Lambda function, which processes data and stores it in an Amazon DynamoDB table. The company wants to implement user authentication, leveraging their existing third-party identity provider that issues OAuth 2.0 tokens. They need a solution that integrates seamlessly with their current setup.

Which solution meets these requirements?

A

Integrate the third-party identity provider with API Gateway. Configure an API Gateway Lambda authorizer to validate OAuth 2.0 tokens from the identity provider. Enforce the Lambda authorizer on all API endpoints. Update the mobile backend to obtain tokens from the identity provider and include them in the Authorization header for API Gateway requests.

B

Integrate the third-party identity provider with Amazon Cognito. Configure Cognito as a JWT authorizer for API Gateway to validate tokens. Enforce the Cognito authorizer on all API endpoints. Update the mobile backend to use Cognito-hosted UI for token retrieval and include tokens in API requests.

C

Integrate the third-party identity provider with AWS IAM. Configure IAM roles with permissions to invoke the API Gateway REST API. Update the mobile backend to assume the IAM role using AWS Security Token Service (STS) and sign requests with SigV4 signatures.

D

Integrate the third-party identity provider with AWS IAM Identity Center. Configure API Gateway to use IAM Identity Center for automatic token validation. Update the mobile backend to retrieve temporary credentials from IAM Identity Center and include them in API requests.

Question #166 / 529

A retail company operates a serverless e-commerce platform on AWS. The platform's inventory service manages product details in an Amazon DynamoDB table. Several other microservices maintain cached copies of product data in different storage solutions. When a product is discontinued, the inventory service deletes it, and all microservices must immediately remove their cached data to prevent outdated information. Which solution ensures immediate deletion across all services?

A

Enable DynamoDB Streams on the DynamoDB table. Use an AWS Lambda function triggered by the stream to send deletion events to an Amazon Simple Queue Service (Amazon SQS) queue. Configure each microservice to poll the queue and delete the product from the DynamoDB table.

B

Configure DynamoDB event notifications to publish deletion events to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe each microservice to the SNS topic and delete the product from the DynamoDB table.

C

Have the inventory service publish a custom event to an Amazon EventBridge event bus upon product deletion. Create an EventBridge rule for each microservice to detect the deletion event and trigger their logic to remove cached data.

D

Configure the inventory service to send deletion messages to an Amazon Simple Queue Service (Amazon SQS) queue. Set up each microservice to filter events from the queue and delete the product from the DynamoDB table.

AWS Elastic Beanstalk

C

AWS Serverless Application Model (AWS SAM)

D

AWS Cloud Development Kit (AWS CDK)

Question #426 / 557

A developer is using AWS Lambda to process messages from an Amazon SQS standard queue. The Lambda function transforms each message and stores the results in an Amazon DynamoDB table. The SQS queue is expected to handle up to 2,000 messages per second. During testing, the developer notices that some entries in DynamoDB are duplicated. Investigation reveals that the same message was processed multiple times by Lambda, with duplicates appearing within 30 seconds of each other. How should the developer resolve this issue?

A

Create an SQS FIFO queue. Enable message deduplication on the SQS FIFO queue.

B

Reduce the maximum Lambda concurrency that the SQS queue can invoke.

C

Use Lambda's temporary storage to keep track of processed message identifiers.

D

Configure a message group ID for every sent message. Enable message deduplication on the SQS standard queue.
