A solutions architect is redesigning a monolithic application to be a loosely coupled application composed of two microservices: Microservice A and Microservice B Microservice A places messages in a mam Amazon Simple Queue Service (Amazon SOS) queue for Microservice B to consume When Microservice B fails to process a message after four retries, the message needs to be removed from the queue and stored for further investigation.
What should the solutions architect do to meet these requirements?

• A.Create an SQS dead-letter queue Microservice B adds failed messages to that queue after it receives and fails to process the message four times.
• B.Create an SQS dead-letter queue Configure the main SQS queue to deliver messages to the dead-letter queue after the message has been received four times.
• C.Create an SQS queue for failed messages Microservice A adds failed messages to that queue after Microservice B receives and fails to process the message four times.
• D.Create an SQS queue for failed messages. Configure the SQS queue for failed messages to pull messages from the main SQS queue after the original message has been received four times.

A company has application services that have been containerized and deployed on multiple Amazon EC2 instances with public IPs. An Apache Kafka cluster has been deployed to the EC2 instances. A PostgreSQL database has been migrated to Amazon RDS for PostgreSQL. The company expects a significant increase of orders on its platform when a new version of its flagship product is released.
What changes to the current architecture will reduce operational overhead and support the product release?

• A.Deploy the application on Amazon Elastic Kubernetes Service (Amazon EKS) with AWS Fargate and enable auto scaling behind an Application Load Balancer. Create additional read replicas for the DB instance. Create an Amazon Managed Streaming for Apache Kafka cluster and configure the application services to use the cluster. Store static content in Amazon S3 behind an Amazon CloudFront distribution.
• B.Deploy the application on a Kubernetes cluster created on the EC2 instances behind an Application Load Balancer. Deploy the DB instance in Multi-AZ mode and enable storage auto scaling. Create an Amazon Managed Streaming for Apache Kafka cluster and configure the application services to use the cluster. Store static content in Amazon S3 behind an Amazon CloudFront distribution.
• C.Create an EC2 Auto Scaling group behind an Application Load Balancer. Create additional read replicas for the DB instance. Create Amazon Kinesis data streams and configure the application services to use the data streams. Store and serve static content directly from Amazon S3.
• D.Create an EC2 Auto Scaling group behind an Application Load Balancer. Deploy the DB instance in Multi-AZ mode and enable storage auto scaling. Create Amazon Kinesis data streams and configure the application services to use the data streams. Store and serve static content directly from Amazon S3.

A workload consists of downloading an image from an Amazon S3 bucket, processing the image, and moving it to another Amazon S3 bucket. An Amazon EC2 instance runs a scheduled task every hour to perform the operation.
How should a Solutions Architect redesign the process so that it is highly available?

• A.Initially copy the images to an attached Amazon EBS volume.
• B.Trigger a Lambda function when a new object is uploaded.
• C.Change the Amazon EC2 instance to compute optimized.
• D.Launch a second Amazon EC2 instance to monitor the health of the first.

A Solutions Architect must create a solution whereby user access to multiple Amazon Aurora MySQL databases is securely managed with short-lived connection credentials.
How can the Solutions Architect meet these requirements?

• A.Use AWS Systems Manager to securely save the connection secrets, and use the secrets while connecting.
• B.Create the user account to use the AWS-provided AWSAuthenticationPlugin with IAM.
• C.Create a database user to run the GRANT statement with a short-lived token.
• D.Use AWS KMS to securely save the connection secrets, and use the secrets while connecting.
