Question #880 / 1019

A company that uses AWS Organizations operates 200 applications across 40 different AWS accounts. The company configured an AWS Cost and Usage Report in the management account, which is delivered to an Amazon S3 bucket replicated to a data collection account. The finance team requires a custom dashboard to display daily Data Transfer costs starting from the beginning of the current month.

Which solution will meet these requirements?

A

Share an Amazon QuickSight dashboard that includes the requested table visual. Configure QuickSight to use AWS DataSync to query the new report.

B

Share an Amazon QuickSight dashboard that includes the requested table visual. Configure QuickSight to use Amazon Athena to query the new report.

C

Share an Amazon CloudWatch dashboard that includes the requested table visual. Configure CloudWatch to use AWS DataSync to query the new report.

D

Share an Amazon CloudWatch dashboard that includes the requested table visual. Configure CloudWatch to use Amazon Athena to query the new report.

Question #713 / 1019

A company operates a video streaming service in the us-east-1 Region. The service allows users globally to upload and stream videos, with uploads capped at 500 MB per video. Popular videos are streamed frequently for several weeks, while others lose popularity within days. The application leverages video metadata to recommend content to users. Which solution provides the MOST cost-effective user access?

A

Store the videos in Amazon DynamoDB. Enable DynamoDB Accelerator (DAX) to cache frequently streamed items.

B

Store the videos in the Amazon S3 Intelligent-Tiering storage class. Store the video metadata and its S3 location in DynamoDB.

C

Store the videos in the Amazon S3 Standard storage class. Configure an S3 Lifecycle policy to transition videos older than 14 days to S3 Standard-Infrequent Access (S3 Standard-IA). Use object tags to manage metadata.

D

Store the videos in the Amazon S3 Glacier storage class. Implement an S3 Lifecycle policy to move videos older than 14 days to S3 Glacier Deep Archive. Store the video metadata and its S3 location in Amazon OpenSearch Service.

Sample Questions

Question #68 / 529

A company uses a Python application on an Amazon EC2 instance to handle data transformation tasks. The application checks an Amazon S3 bucket every 15 minutes and processes files, with each file taking roughly 7 minutes to complete. The application skips files that have already been processed. CloudWatch metrics reveal the EC2 instance is idle 50% of the time due to processing delays. The company aims to improve scalability, ensure high availability, and minimize operational management.

Which solution MOST cost-effectively meets these requirements?

A

Convert the data transformation application into an AWS Lambda function. Configure S3 event notifications to trigger the Lambda function automatically when new files are uploaded to the S3 bucket.

B

Set up an Amazon Simple Queue Service (SQS) queue. Enable S3 event notifications to send messages to the queue. Deploy an EC2 Auto Scaling group starting with one instance. Modify the application to poll the SQS queue and process files based on received messages.

C

Containerize the data transformation application and deploy it on the existing EC2 instance. Configure the container to continuously poll the S3 bucket for new files and process them as they arrive.

D

Migrate the application to a container running on Amazon Elastic Container Service (ECS) with AWS Fargate. Use an Amazon EventBridge rule to invoke the Fargate task via the RunTask API whenever a new file is uploaded to the S3 bucket.

Question #171 / 529

A company uses an AWS CodeCommit repository and requires a real-time backup of the repository data in a secondary AWS Region. Which solution fulfills this requirement?

A

Configure AWS Application Migration Service to replicate the CodeCommit repository to the second Region.

B

Use AWS Backup to create a daily backup of the CodeCommit repository and enable cross-Region copying to the secondary Region.

C

Create an Amazon EventBridge rule triggered by repository push events to invoke an AWS Lambda function. The Lambda function clones the repository, packages it into a .zip file, and copies the file to an S3 bucket in the secondary Region.

D

Set up an Amazon S3 Cross-Region Replication (CRR) rule to automatically replicate the CodeCommit repository's underlying storage to the second Region.

Sample Questions

Question #279 / 557

A video processing platform uses Amazon S3 to store video files. Each uploaded video is analyzed by an external machine learning service to generate metadata, which takes between 1 to 24 hours. The results are stored in an Amazon DynamoDB table with the S3 object key as the primary key. The application must automatically tag each S3 object with the generated metadata once available.

What should a developer do to meet this requirement in the MOST operationally efficient manner?

A

Create an AWS Lambda function triggered by s3:ObjectCreated events. The function writes the S3 key to an Amazon SQS queue with a 24-hour visibility timeout. A second Lambda function polls the queue, retrieves metadata from DynamoDB, and tags the S3 object.

B

Develop an AWS Lambda function triggered by s3:ObjectCreated events. Integrate this into an AWS Step Functions workflow with a Wait state set to 24 hours. A second Lambda function retrieves metadata from DynamoDB and applies the tags after the wait.

C

Implement a Lambda function that lists all untagged S3 objects, fetches metadata via a REST API, and tags them. Use an Amazon EventBridge scheduled rule to invoke this function periodically.

D

Deploy a script on an EC2 instance that queries DynamoDB for new metadata and tags S3 objects. Use crontab to run the script hourly.

Question #162 / 557

A developer is encountering frequent deployment failures in the AWS Lambda functions managed by their team's TypeScript application. To reduce these failures, the developer aims to establish automated testing that replicates the Lambda execution environment. The solution must allow developers to execute tests locally and be incorporated into the CI/CD pipeline prior to deployment using the AWS Cloud Development Kit (AWS CDK).

Which approach fulfills these requirements?

A

Use CDK synth to generate CloudFormation templates. Create test scripts that invoke the Lambda functions using these templates. Document the process for the team and update the CI/CD pipeline to execute the test scripts during deployment.

B

Implement a mocking framework to simulate the Lambda environment. Write unit tests that directly call the handler function with mock events. Document how to run the tests locally and update the CI/CD pipeline to include the unit testing framework.

C

Install the AWS Serverless Application Model (AWS SAM) CLI. Use the SAM local generate-event command to create test events. Develop automated test scripts that invoke the Lambda functions with SAM local invoke. Document the scripts for the team and integrate them into the CI/CD pipeline before CDK deployment.

D

Create a Docker container configured with the Node.js Lambda runtime. Develop test scripts to invoke the Lambda functions within the container. Document the Docker setup for local testing and modify the CI/CD pipeline to run the containerized tests.
