A company wants to move a multi-tiered application from on premises to the AWS Cloud to improve the application's performance. The application consists of application tiers that communicate with each other by way of
Which solution moots these and is the MOST operationally efficient?

• A.Use Amazon API Gateway and direct transactions to the AWS Lambda functions as the application layer Use Amazon Simple Queue Service (Amazon SOS) as the communication layer between application services.
• B.Use Amazon CloudWatch metrics to analyze the application performance history to determine the servers' peak utilization during the performance failures Increase the size or the application servers Amazon EC2 instance to meet the peak requirements
• C.Use Amazon Simple Notification Service (Amazon SNS) to handle the messaging between application servers running on Amazon EC2 m an Auto Scaling group Use Amazon CloudWatch to monitor the SNS queue length and scale up and down as required.
• D.Use Amazon Simple Queue Service (Amazon SOS) to handle the messaging between application servers running on Amazon EC2 In an Auto Seeing group Use Amazon CloudWatch to monitor the SOS queue length and scale up when communication failures are detected.

A company has an automobile sales website that stores its listings in a database on Amazon RDS When an automobile is sold the listing needs to be removed from the website and the data must be sent to multiple target systems.
Which design should a solutions architect recommend?

• A.Subscribe to an RDS event notification and send an Amazon Simple Queue Service (Amazon SQS) queue fanned out to multiple Amazon Simple Notification Service (Amazon SNS) topics Use AWS Lambda functions to update the targets
• B.Subscribe to an RDS event notification and send an Amazon Simple Notification Service (Amazon SNS) topic fanned out to multiple Amazon Simple Queue Service (Amazon SQS) queues Use AWS Lambda functions to update the targets
• C.Create an AWS Lambda function triggered when the database on Amazon RDS is updated to send the information to an Amazon Simple Queue Service (Amazon SQS> queue for the targets to consume
• D.Create an AWS Lambda function triggered when the database on Amazon RDS is updated to send the information to an Amazon Simple Queue Service (Amazon SQS) FIFO queue for the targets to consume

A law firm needs to share information with the public. The information includes hundreds of files that must be publicly readable. Modifications or deletions of the files by anyone before a designated future date are prohibited.
Which solution will meet these requirements in the MOST secure way?

• A.Upload all tiles to an Amazon S3 bucket that is configured for static website hosting. Grant read-only IAM permissions to any AWS principals that access the S3 bucket until the designated date.
• B.Upload all files to an Amazon S3 bucket that is configured for static website hosing. Select the folder that contains the files. Use S3 Object Lock with a retention period m accordance with the designated date Grant read-only IAM permissions to any AWS principals that access the S3 bucket
• C.Create a new Amazon S3 bucket with S3 Versioning enabled. Use S3 Object Lock with a retention period in accordance with the designated dale. Configure the S3 bucket for static website hosting Set an S3 bucket policy to allow read-only access to the objects.
• D.Create a new Amazon S3 bucket with S3 Versioning enabled Configure an event trigger to run an AWS Lambda function in case of object modification or deletion Configure the Lambda function to replace the objects with the original versions from a private S3 bucket

A company hosts a multi-tier web application that uses an Amazon Aurora MySQL DB cluster for storage. The application tier is hosted on Amazon EC2 instances The company's IT security guidelines mandate that the database credentials be encrypted and rotated every 14 days
What should a solutions architect do to meet this requirement with the LEAST operational effort?

• A.Store a file that contains the credentials in an AWS Key Management Service (AWS KMS) encrypted Amazon Elastic File System (Amazon EFS) file system Mount the EFS file system in all EC2 instances of the application tier. Restrict the access to the file on the file system so that the application can read the file and that only super users can modify the file Implement an AWS Lambda function that rotates the key in Aurora every 14 days and writes new credentials into the file
• B.Store a file that contains the credentials in an AWS Key Management Service (AWS KMS) encrypted Amazon S3 bucket that the application uses to load the credentials Download the file to the application regularly to ensure that the correct credentials are used Implement an AWS Lambda function that rotates the Aurora credentials every 14 days and uploads these credentials to the file in the S3 bucket
• C.Create two parameters m AWS Systems Manager Parameter Store one for the user name as a string parameter and one that uses the SecureStnng type for the password Select AWS Key Management Service (AWS KMS) encryption for the password parameter, and load these parameters in the application tier Implement an AWS Lambda function that rotates the password every 14 days.
• D.Create a new AWS Key Management Service (AWS KMS) encryption key Use AWS Secrets Manager to create a new
  secret that uses the KMS key with the appropriate credentials Associate the secret with the Aurora DB cluster Configure a custom rotation period of 14 days

A company is migrating a large, mission-critical database to AWS. A solutions architect has decided to use an Amazon RDS for MySQL Multi-AZ DB instance that Is deployed with 80,000 Provisioned IOPS for storage The solutions architect is using AWS Database Migration Service (AWS DMS) to perform the data migration. The migration is taking longer than expected, and the company wants to speed up the process. The company's network team has ruled out bandwidth as a limiting factor.
Which actions should the solutions architect take to speed up the migration? (Select TWO.)

• A.Restart the DMS task on a new DMS instance with transfer acceleration enabled.
• B.Create a new DMS instance that has a larger instance size.
• C.Turn off logging on the target DB instance until the initial load is complete.
• D.Disable Multi-AZ on the target DB instance.
• E.Change the storage type on the target DB instance to Amazon Elastic Block Store (Amazon EBS) General Purpose SSD (gp2).
