A retail company processes point-of-sale data on application servers in its data center and writes outputs to an Amazon DynamoDB table.The data center is connected to the company’s VPC with an AWS Direct Connect (DX) connection, and the application servers require a consistent network connection at speeds greater than 2 Gbps.The company decides that the DynamoDB table needs to be highly available and fault tolerant.The company policy states that the data should be available across two regions.What changes should the company make to meet these requirements?Read More →

A company has a solution that analyzes weather data from thousands of weather stations.The weather stations send the data over an Amazon API Gateway REST API that has an AWS Lambda function integration.The Lambda function calls a third-party service for data pre-processing.The third-party service gets overloaded and fails the pre-processing, causing a loss of data.A solutions architect must improve the resiliency of the solution.The solutions architect must ensure that no data is lost and that data can be processed later if failures occur.What should the solutions architect do to meet these requirements?Read More →

A company built an ecommerce website on AWS using a three-tier web architecture.The application is Java-based and composed of an Amazon CloudFront distribution, an Apache web server layer of Amazon EC2 instances in an Auto Scaling group, and a backend Amazon Aurora MySQL database.Last month, during a promotional sales event, users reported errors and timeouts while adding items to their shopping carts.The operations team recovered the logs created by the web servers and reviewed Aurora DB cluster performance metrics.Some of the web servers were terminated before logs could be collected and the Aurora metrics were not sufficient for query performance analysis.Which combination of steps must the solutions architect take to improve application performance visibility during peak traffic events? (Choose three.)Read More →

A company wants to move an application from on premises to the AWS Cloud.The application uses MySQL servers to store backend data.However, the application does not scale properly.The databases have become unresponsive as the user base has increased.The company needs a solution to make the application highly available with low latency across multiple AWS Regions.The solution must require the least possible operational overhead and development effort.Which solution will meet these requirements?Read More →

A company is migrating to the cloud.It wants to evaluate the configurations of virtual machines in its existing data center environment to ensure that it can size new Amazon EC2 instances accurately.The company wants to collect metrics, such as CPU, memory, and disk utilization, and it needs an inventory of what processes are running on each instance.The company would also like to monitor network connections to map communications between servers.Which would enable the collection of this data MOST cost effectively?Read More →

A startup company recently migrated a large ecommerce website to AWS.The website has experienced a 70% increase in sales.Software engineers are using a private GitHub repository to manage code.The DevOps team is using Jenkins for builds and unit testing.The engineers need to receive notifications for bad builds and zero downtime during deployments.The engineers also need to ensure any changes to production are seamless for users and can be rolled back in the event of a major issue.The software engineers have decided to use AWS CodePipeline to manage their build and deployment process.Which solution will meet these requirements?Read More →

A company is developing a web application that runs on Amazon EC2 instances in an Auto Scaling group behind a public-facing Application Load Balancer (ALB).Only users from a specific country are allowed to access the application.The company needs the ability to log the access requests that have been blocked.The solution should require the least possible maintenance.Which solution meets these requirements?Read More →

A company uses an on-premises data analytics platform.The system is highly available in a fully redundant configuration across 12 servers in the company’s data center.The system runs scheduled jobs, both hourly and daily, in addition to one-time requests from users.Scheduled jobs can take between 20 minutes and 2 hours to finish running and have tight SLAs.The scheduled jobs account for 65% of the system usage.User jobs typically finish running in less than 5 minutes and have no SLA.The user jobs account for 35% of system usage.During system failures, scheduled jobs must continue to meet SLAs.However, user jobs can be delayed.A solutions architect needs to move the system to Amazon EC2 instances and adopt a consumption-based model to reduce costs with no long-term commitments.The solution must maintain high availability and must not affect the SLAs.Which solution will meet these requirements MOST cost-effectively?Read More →

A company is migrating an on-premises application and a MySQL database to AWS.The application processes highly sensitive data, and new data is constantly updated in the database.The data must not be transferred over the internet.The company also must encrypt the data in transit and at rest.The database is 5 TB in size.The company already has created the database schema in an Amazon RDS for MySQL DB instance.The company has set up a 1 Gbps AWS Direct Connect connection to AWS.The company also has set up a public VIF and a private VIF.A solutions architect needs to design a solution that will migrate the data to AWS with the least possible downtime.Which solution will meet these requirements?Read More →
