A company offers a food delivery service that is growing rapidly Because of the growth the company's order processing system is experiencing scaling problems during peak traffic hours. The current architecture includes the following;* A group of Amazon EC2 instances that run in an Amazon EC2 Auto Scaling group to collect orders from the application* Another group of EC2 instances that run in an Amazon EC2 Auto Scaling group to fulfill ordersThe order collection process occurs quickly, but the order fulfillment process can take longer Data must not be lost because of a scaling eventA solutions architect must ensure that the order collection process and the order fulfillment process can both scale properly during peak traffic hours The solution must optimize utilization of the company's AWS resourcesWhich solution meets these requirements'?

• Use Amazon CloudWatch metrics to monitor the CPU of each instance in the Auto Scaling groups. Configure each Auto Scaling group's minimum capacity according to peak workload values
• Use Amazon CloudWatch metrics to monitor the CPU of each instance in the Auto Scaling groups Configure a CloudWatch alarm to invoke an Amazon Simple Notification Service (Amazon SNS) topic that creates additional Auto Scaling groups on demand

• Provision two Amazon Simple Queue Service (Amazon SQS) queues one for order collection and another for order fulfillment. Configure the EC2 instances to poll their respective queue. Create a metric based on a backlog per instance calculation Scale the Auto Scaling groups based on this metric.

A Company has an application that provides marketing services to stores. The services are based on previous purchased by store customers. The stores upload transaction data to the company through SFTP, and the data is processed an analysed to generate new marketing offers. Some of the files can exceed 200 GB in size.Recently, the company discovered that some of the stores have uploaded file that contains personality identifiable information (PII) that should not have included. The company wants administrators to be alerted if PII is shared again. The company also wants to automate remediation.

If objects contain Pll. use Amazon Simple Email Service (Amazon STS) to trigger a notification to the administrators and trigger on S3 Lifecycle policy to remove the objects mot contain PII.

A company hosts an application on multiple Amazon EC2 instances The application processes messages from an Amazon SQS queue writes to an Amazon RDS table and deletes the message from the queue Occasional duplicate records are found in the RDS table. The SQS queue does not contain any duplicate messages.What should a solutions architect do to ensure messages are being processed once only?

• Use the CreateQueue API call to create a new queue
• Use the Add Permission API call to add appropriate permissions
• Use the ReceiveMessage API call to set an appropriate wail time
• Use the ChangeMessageVisibility APi call to increase the visibility timeout

A company wants to host a scalable web application on AWS The application will be accessed by users from different geographic regions of the world. Application users will be able to download and upload unique data up to gigabytes in size. The development team wants a cost-effective solution to minimize upload and download latency and maximize performanceWhat should a solutions architect do to accomplish this?

• Use Amazon S3 with Transfer Acceleration to host the application.
• Use Amazon S3 with CacheControl headers to host the application.
• Use Amazon EC2 with Auto Scaling and Amazon CloudFront to host the application
• Use Amazon EC2 with Auto Scaling and Amazon ElastiCache to host the application

A company is migrating its on-premises PostgreSQL database to Amazon Aurora PostgreSQL. The on-premises database must remain online and accessible during the migration. The Aurora database must remain synchronized with the on-premises database.Which combination of actions must a solutions architect take to meet these requirements? (Select TWO.)

• Create an ongoing replication task.
• Create a database backup of the on-premises database
• Create an AWS Database Migration Service (AWS DMS) replication server
• Convert the database schema by using the AWS Schema Conversion Tool (AWS SCT).
• Create an Amazon EventBridge (Amazon CloudWatch Events) rule to monitor the database synchronization

An online gaming company is designing a game that is expected to be popular all over the world A solutions architect needs to define an AWS Cloud architecture that supports near-real-time recording and displaying of current game statistics for each player along with the names of the top 25 players in the world at any given timeWhich AWS database solution and configuration should the solutions architect use to meet these requirements'?

• Use Amazon RDS for MySQL as the data store for player activity Configure the RDS DB instance for Multi-AZ support
• Use Amazon DynamoDB as the data store for player activity Configure DynamoDB Accelerator (DAX) for the player data
• Use Amazon DynamoDB as the data store for player activity Configure global tables in each required AWS Region for the player data
• Use Amazon RDS for MySQL as the data store for player activity Configure cross-Region read replicas in each required AWS Region based on player proximity

A company requires that all version of object in its Amazon S3 bucket be retained. Current object versions will be frequently accessed during the first 30 days, after which they will be rarely accessed and must be retrievable within 5 minutes. Previous object versions need to be kept forever, will be rarely accessed, and can be retrieved within 1 week. All store solutions must be highly available and highly durableWhat should a solutions architect recommend to meet these requirements in the MOST costs-effective manner?

• Create an S3 lifecycle policy tor the bucket that moves current object versions horn S3 Standard storage lo S3 Glacier after 30 days and moves previous object versions to S3 Glacier after 1 day
• Create an S3 lifecycle policy for the bucket that moves current object versions from S3 Standard storage to S3 Glacier after 30 days and moves previous object versions to S3 Glacier Deep Archive after 1 day.
• Create an S3 lifecycle policy for the bucket that moves current object versions from S3 Standard storage to S3 standard-infrequent Access (S3 Standard-IA) after 30 days and moves previous object versions to S3 Glacier Deep Archive after 1 day.

A solutions architect is redesigning a monolithic application to be a loosely coupled application composed of two microservices: Microservice A and Microservice BMicroservice 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?

• 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.
• 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.
• 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.
• 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.
