A solutions architect is designing a multi-tier application for a company The application\\’s users upload images from a
mobile device. The application generates a thumbnail of each image and returns a message to the user to confirm that
the image was uploaded successfully.
The thumbnail generation can take up to 60 seconds, but the company wants to provide a faster response time to its
users to notify them that the original image was received.
The solutions architect must design the application to asynchronously dispatch requests to the different application tiers.

as an event source to invoke the Lambda function.
B. Create an AWS Step Functions workflow Configure Step Functions to handle the orchestration between the
application tiers and alert the user when thumbnail generation is complete
C. Create an Amazon Simple Queue Service (Amazon SQS) message queue. As images are uploaded, place a
message on the SQS queue for thumbnail generation. Alert the user through an application message that the image
D. Create Amazon Simple Notification Service (Amazon SNS) notification topics and subscriptions Use one subscription
with the application to generate the thumbnail after the image upload is complete. Use a second subscription to
message the user\\’s mobile app by way of a push notification after thumbnail generation is complete.
A company is building a payment application that must be highly available even during regional service disruptions A
solutions architect must design a data storage solution that can be easily replicated and used in other AWS Regions.

to be immediately available to generate reports The development team also needs to use SQL.
Which data storage solution meets these requirements\\’?
A. Amazon Aurora Global Database
B. Amazon DynamoDB global tables
C. Amazon S3 with cross-Region replication and Amazon Athena
D. MySQL on Amazon EC2 instances with Amazon Elastic Block Store (Amazon EBS) snapshot replication
A company recently started using Amazon Aurora as the data store for its global ecommerce application. When large
reports are run, developers report that the ecommerce application is performing poorly.
After reviewing metrics in Amazon CloudWatch, a solutions architect finds that the ReadlOPS and CPU Utilization metrics are spiking when monthly reports run.
What is the MOST cost-effective solution?
A. Migrate the monthly reporting to Amazon Redshift.
B. Migrate the monthly reporting to an Aurora Replica.
C. Migrate the Aurora database to a larger instance class.
D. Increase the Provisioned IOPS on the Aurora instance.
A company hosts a two-tier website that runs on Amazon EC2 instances. The website has a database that runs on
Amazon RDS for MySQL.
All users are required to log in I customized pages.
The website typically experiences low traffic. Occasionally, the website experiences sudden increases in traffic and
During these increases in traffic, write load. A solutions architect must improve the website\\’s availability without changing the application code.
What should the solutions architect do to meet these requirements?
A. Create an Amazon ElastiCache for Redis cluster. Configure the application to cache common database queries in the
B. Create an Auto Scaling group. Configure Amazon CloudWatch alarms to scale the number of EC2 instances based
on the percentage of CPU in use during the traffic……
C. Create an Amazon CloudFront distribution that points to the EC2 instances as the origin.Enable caching of dynamic
content, and configure a write throttle from ……database.
D. Migrate the database to an Amazon Aurora Serverless cluster. Set the maximum Aurora capacity units (ACUs) to a
value high enough to respond to the traffic incre………..instances to connect to the Aurora database.

Lrfecycle policies to delete the snapshots after 2 years.
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.

B. Implement CloudFront events with Lambda@Edge to run the website\\’s data processing.
C. Modify the CloudFront price class to include only the locations of the countries that are served.
D. Implement a CloudFront Secure Sockets Layer (SSL) certificate to push security closer to the locations of the
countries that are served.
A. This could be an option, since static content won\\’t change that much.
B. It\\’s a static website, there is no processing.
D. What does an SSL have to do with reducing costs?
CloudFront edge locations are grouped into geographic regions, and we\\’ve grouped regions into price classes.
The default price class includes all regions. Another price class includes most regions (the United States; Canada; Europe; Hong Kong, Philippines, South Korea, Taiwan, and Singapore; Japan; India; South Africa; and Middle East regions) but excludes the most expensive regions.
A third price class includes only the least expensive regions (the United States, Canada, and Europe regions).
