A company is migrating an application from on-premises infrastructure to the AWS Cloud.During migration design meetings, the company expressed concerns about the availability and recovery options for its legacy Windows file server.The file server contains sensitive business-critical data that cannot be recreated in the event of data corruption or data loss.According to compliance requirements, the data must not travel across the public internet.The company wants to move to AWS managed services where possible.The company decides to store the data in an Amazon FSx for Windows File Server file system.A solutions architect must design a solution that copies the data to another AWS Region for disaster recovery (DR) purposes.Which solution will meet these requirements?Read More →

A company had a tight deadline to migrate its on-premises environment to AWS.It moved over Microsoft SQL Servers and Microsoft Windows Servers using the virtual machine import/export service and rebuild other applications native to the cloud.The team created both Amazon EC2 databases and used Amazon RDS.Each team in the company was responsible for migrating their applications, and they have created individual accounts for isolation of resources.The company did not have much time to consider costs, but now it would like suggestions on reducing its AWS spend.Which steps should a Solutions Architect take to reduce costs?Read More →

A company is running a serverless application that consists of several AWS Lambda functions and Amazon DynamoDB tables.The company has created new functionality that requires the Lambda functions to access an Amazon Neptune DB cluster.The Neptune DB cluster is located in three subnets in a VPC.Which of the possible solutions will allow the Lambda functions to access the Neptune DB cluster and DynamoDB tables? (Choose two.)Read More →

A company is running an image-processing service in the AWS Cloud.Users upload images to an Amazon S3 bucket for processing.When an image is uploaded to the S3 bucket, several microservices that are based on AWS Lambda functions need to perform different processing tasks on the image.Each task’s processing must start immediately after an image is uploaded.Which solution will meet these requirements?Read More →

A company is running a three-tier web application in an on-premises data center.The frontend is served by an Apache web server, the middle tier is a monolithic Java application, and the storage tier is a PostgreSQL database.During a recent marketing promotion, customers could not place orders through the application because the application crashed.An analysis showed that all three tiers were overloaded.The application became unresponsive, and the database reached its capacity limit because of read operations.The company already has several similar promotions scheduled in the near future.A solutions architect must develop a plan for migration to AWS to resolve these issues.The solution must maximize scalability and must minimize operational effortWhich combination of steps will meet these requirements? (Choose three.)Read More →

A company has decided to move some workloads onto AWS to create a grid environment to run market analytics.The grid will consist of many similar instances, spun-up by a job-scheduling function.Each time a large analytics workload is completed, a new VPC is deployed along with job scheduler and grid nodes.Multiple grids could be running in parallel.Key requirements are:✑ Grid instances must communicate with Amazon S3 to retrieve data to be processed.✑ Grid instances must communicate with Amazon DynamoDB to track intermediate data.✑ The job scheduler needs only to communicate with the Amazon EC2 API to start new grid nodes.A key requirement is that the environment has no access to the internet, either directly or via the on-premises proxy.However, the application needs to be able to seamlessly communicate to Amazon S3, Amazon DynamoDB, and Amazon EC2 API, without the need for reconfiguration for each new deployment.Which of the following should the Solutions Architect do to achieve this target architecture? (Choose three.)Read More →

A company requires that all internal application connectivity use private IP addresses.To facilitate this policy, a solutions architect has created interface endpoints to connect to AWS Public services.Upon testing, the solutions architect notices that the service names are resolving to public IP addresses, and that internal services cannot connect to the interface endpoints.Which step should the solutions architect take to resolve this issue?Read More →

A company must deploy multiple independent instances of an application.The front-end application is internet accessible.However, corporate policy stipulates that the backends are to be isolated from each other and the internet, yet accessible from a centralized administration server.The application setup should be automated to minimize the opportunity for mistakes as new instances are deployed.Which option meets the requirements and MINIMIZES costs?Read More →

A company operates a static content distribution platform that serves customers globally.The customers consume content from their own AWS accounts.The company serves its content from an Amazon S3 bucket.The company uploads the content from its on-premises environment to the S3 bucket by using an S3 File Gateway.The company wants to improve the platform’s performance and reliability by serving content from the AWS Region that is geographically closest to customers.The company must route the on-premises data to Amazon S3 with minimal latency and without public internet exposure.Which combination of steps will meet these requirements with the LEAST operational overhead? (Choose two.)Read More →
