A solutions architect needs to implement a solution that can handle up to 5,000 messages per second. The solution must publish messages as events to multiple consumers. The messages are up to 500 KB in size. The message consumers need to have the ability to use multiple programming languages to consume the messages with minimal latency. The solution must retain published messages for more than 3 months. The solution must enforce strict ordering of the messages.
A. Publish messages to an Amazon Kinesis Data Streams data stream. Enable enhanced
fan-out. Ensure that consumers ingest the data stream by using dedicated throughput.
B. Publish messages to an Amazon Simple Notification Service (Amazon SNS) topic. Ensure that consumers use an Amazon Simple Queue Service (Amazon SQS) FIFO queue to subscribe to the topic.
C. Publish messages to Amazon EventBridge. Allow each consumer to create rules to deliver messages to the consumer's own target.
D. Publish messages to an Amazon Simple Notification Service (Amazon SNS) topic. Ensure that consumers use Amazon Data Firehose to subscribe to the topic.

A company is building a serverless application to process large video files that users upload. The application performs multiple tasks to process each video file. Processing can take up to 30 minutes for the largest files. The company needs a scalable architecture to support the processing application. Which solution will meet these requirements?
A. Store the uploaded video files in Amazon Elastic File System (Amazon EFS). Configure
a schedule in Amazon EventBridge Scheduler to invoke an AWS Lambda function
periodically to check for new files. Configure the Lambda function to perform all the
processing tasks.
B. Store the uploaded video files in Amazon Elastic File System (Amazon EFS). Configure an Amazon EFS event notification to start an AWS Step Functions workflow that uses AWS Fargate tasks to perform the processing tasks.
C. Store the uploaded video files in Amazon S3. Configure an Amazon S3 event
notification to send an event to Amazon EventBridge when a user uploads a new video file.
Configure an AWS Step Functions workflow as a target for an EventBridge rule. Use the
workflow to manage AWS Fargate tasks to perform the processing tasks.
D. Store the uploaded video files in Amazon S3. Configure an Amazon S3 event
notification to invoke an AWS Lambda function when a user uploads a new video file.
Configure the Lambda function to perform all the processing tasks.

A company has a payroll application that runs in the AWS Cloud. The application uses an Amazon Aurora MySQL database cluster for data storage. The company’s auditing team needs to review the last 90 days of payroll data. A solutions architect needs to design a solution to provide the auditing team access to the payroll data. Which solution will meet these requirements with the MOST operational efficiency?
A. Use Aurora automated backups. Restore the database by using point-in-time recovery.
B. Create a backup plan by using AWS Backup with point-in-time recovery. Restore the database by using the backups from the backup vault.
C. Create daily manual backups of the Aurora cluster for the last 90 days. Restore the databases by using the backups. Delete the older backup files by using scripted CLI calls.
D. Create a backup plan by using AWS Backup with the daily backup option. Set the retention to 90 days. Restore the database by using the backups from the backup vault.
A company uses an Amazon EC2 Auto Scaling group to host an API. The EC2 instances are in a target group that is associated with an Application Load Balancer (ALB). The company stores data in an Amazon Aurora PostgreSQL database. The API has a weekly maintenance window. The company must ensure that the API returns a static maintenance response during the weekly maintenance window. Which solution will meet this requirement with the LEAST operational overhead?
A. Create a table in Aurora PostgreSQL that has fields to contain keys and values. Create
a key for a maintenance flag. Set the flag when the maintenance window starts. Configure
the API to query the table for the maintenance flag and to return a maintenance response if
the flag is set. Reset the flag when the maintenance window is finished.
B. Create an Amazon Simple Queue Service (Amazon SQS) queue. Subscribe the EC2 instances to the queue. Publish a message to the queue when the maintenance window starts. Configure the API to return a maintenance message if the instances receive a maintenance start message from the queue. Publish another message to the queue when the maintenance window is finished to restore normal operation.
C. Create a listener rule on the ALB to return a maintenance response when the path on a request matches a wildcard. Set the rule priority to one. Perform the maintenance. When the maintenance window is finished, delete the listener rule.
D. Create an Amazon Simple Notification Service (Amazon SNS) topic Subscribe the EC2 instances to the topic Publish a message to the topic when the maintenance window starts. Configure the API to return a maintenance response if the instances receive the maintenance start message from the topic. Publish another message to the topic when the maintenance window finshes to restore normal operation.
A finance company uses backup software to back up its data to physical tape storage onpremises. To comply with regulations, the company needs to store the data for 7 years. The company must be able to restore archived data within one week when necessary. The company wants to migrate the backup data to AWS to reduce costs. The company does not want to change the current backup software. Which solution will meet these requirements MOST cost-effectively?
A. Use AWS Storage Gateway Tape Gateway to copy the data to virtual tapes. Use AWS
DataSync to migrate the virtual tapes to the Amazon S3 Standard-Infrequent Access (S3
Standard-IA). Change the target of the backup software to S3 Standard-IA.
B. Convert the physical tapes to virtual tapes. Use AWS DataSync to migrate the virtual tapes to Amazon S3 Glacier Flexible Retrieval. Change the target of the backup software to the S3 Glacier Flexible Retrieval.
C. Use AWS Storage Gateway Tape Gateway to copy the data to virtual tapes. Migrate the virtual tapes to Amazon S3 Glacier Deep Archive. Change the target of the backup software to the virtual tapes.
D. Convert the physical tapes to virtual tapes. Use AWS Snowball Edge storage-optimized devices to migrate the virtual tapes to Amazon S3 Glacier Flexible Retrieval. Change the target of the backup software to S3 Glacier Flexible Retrieval.

A. Create an IAM role, and attach the role to each EC2 instance profile. Use an identitybased
policy to grant the new IAM role access to the secret that contains the database
credentials.

policy to grant the new IAM user access to the secret that contains the database
credentials.
