A company’s web application has reliability issues.The application serves customers globally.The application runs on a single Amazon EC2 instance and performs read-intensive operations on an Amazon RDS for MySQL database.During high load, the application becomes unresponsive and requires a manual restart of the EC2 instance.A solutions architect must improve the application’s reliability.Which solution will meet this requirement with the LEAST development effort?Read More →

A company has a photo sharing social networking application.To provide a consistent experience for users, the company performs some image processing on the photos uploaded by users before publishing on the application.The image processing is implemented using a set of Python libraries.The current architecture is as follows:✑ The image processing Python code runs in a single Amazon EC2 instance and stores the processed images in an Amazon S3 bucket named ImageBucket.✑ The front-end application, hosted in another bucket, loads the images from ImageBucket to display to users.With plans for global expansion, the company wants to implement changes in its existing architecture to be able to scale for increased demand on the application and reduce management complexity as the application scales.Which combination of changes should a solutions architect make? (Choose two.)Read More →

A company needs to implement disaster recovery for a critical application that runs in a single AWS Region.The application’s users interact with a web frontend that is hosted on Amazon EC2 instances behind an Application Load Balancer (ALB).The application writes to an Amazon RDS for MySQL DB instance.The application also outputs processed documents that are stored in an Amazon S3 bucket.The company’s finance team directly queries the database to run reports.During busy periods, these queries consume resources and negatively affect application performance.A solutions architect must design a solution that will provide resiliency during a disaster.The solution must minimize data loss and must resolve the performance problems that result from the finance team’s queries.Which solution will meet these requirements?Read More →

A company is migrating its data center from on premises to the AWS Cloud.The migration will take several months to complete.The company will use AmazonRoute 53 for private DNS zones.During the migration, the company must keep its AWS services pointed at the VPC’s Route 53 Resolver for DNS.The company also must maintain the ability to resolve addresses from its on-premises DNS server.A solutions architect must set up DNS so that Amazon EC2 instances can use native Route 53 endpoints to resolve on-premises DNS queries.Which configuration will meet these requirements?Read More →

A company wants to containerize a multi-tier web application and move the application from an on-premises data center to AWS.The application includes web.application, and database tiers.The company needs to make the application fault tolerant and scalable.Some frequently accessed data must always be available across application servers.Frontend web servers need session persistence and must scale to meet increases in traffic.Which solution will meet these requirements with the LEAST ongoing operational overhead?Read More →

A company manages hundreds of AWS accounts centrally in an organization in AWS Organizations.The company recently started to allow product teams to create and manage their own S3 access points in their accounts.The S3 access points can be accessed only within VPCs, not on the Internet.What is the MOST operationally efficient way to enforce this requirement?Read More →

A company is migrating a document processing workload to AWS.The company has updated many applications to natively use the Amazon S3 API to store, retrieve, and modify documents that a processing server generates at a rate of approximately 5 documents every second.After the document processing is finished, customers can download the documents directly from Amazon S3.During the migration, the company discovered that it could not immediately update the processing server that generates many documents to support the S3 API.The server runs on Linux and requires fast local access to the files that the server generates and modifies.When the server finishes processing, the files must be available to the public for download within 30 minutes.Which solution will meet these requirements with the LEAST amount of effort?Read More →

An AWS customer has a web application that runs on premises.The web application fetches data from a third-party API that is behind a firewall.The third party accepts only one public CIDR block in each client’s allow list.The customer wants to migrate their web application to the AWS Cloud.The application will be hosted on a set of Amazon EC2 instances behind an ApplicationLoad Balancer (ALB) in a VPC.The ALB is located in public subnets.The EC2 instances are located in private subnets.NAT gateways provide internet access to the private subnets.How should a solutions architect ensure that the web application can continue to call the third-party API after the migration?Read More →

A company is creating a sequel for a popular online game.A large number of users from all over the world will play the game within the first week after launch.Currently, the game consists of the following components deployed in a single AWS Region:• Amazon S3 bucket that stores game assets• Amazon DynamoDB table that stores player scoresA solutions architect needs to design a multi-Region solution that will reduce latency, improve reliability, and require the least effort to implement.What should the solutions architect do to meet these requirements?Read More →
