A global ecommerce company has many data centers around the world.With the growth of its stored data, the company needs to set up a solution to provide scalable storage for legacy on-premises file applications.The company must be able to take point-in-time copies of volumes by using AWS Backup and must retain low-latency access to frequently accessed data.The company also needs to have storage volumes that can be mounted as Internet Small Computer System Interface (iSCSI) devices from the company’s on-premises application servers.Which solution will meet these requirements?Read More →

A company is running a large application on premises.Its technology stack consists of Microsoft .NET for the web server platform and Apache Cassandra for the database.The company wants to migrate this application to AWS to improve service reliability.The IT team also wants to reduce the time it spends on capacity management and maintenance of this infrastructure.The Development team is willing and available to make code changes to support the migration.Which design is the LEAST complex to manage after the migration?Read More →

A company has an application that uses AWS Key Management Service (AWS KMS) to encrypt and decrypt data.The application stores data in an Amazon S3 bucket in an AWS Region.Company security policies require the data to be encrypted before the data is placed into the S3 bucket.The application must decrypt the data when the application reads files from the S3 bucket.The company replicates the S3 bucket to other Regions.A solutions architect must design a solution so that the application can encrypt and decrypt data across Regions.The application must use the same key to decrypt the data in each Region.Which solution will meet these requirements?Read More →

A company runs a Windows Server host in a public subnet that is configured to allow a team of administrators to connect over RDP to troubleshoot issues with hosts in a private subnet.The host must be available at all times outside of a scheduled maintenance window, and needs to receive the latest operating system updates within 3 days of release.What should be done to manage the host with the LEAST amount of administrative effort?Read More →

A company is running a commercial Apache Hadoop cluster on Amazon EC2.This cluster is being used daily to query large files on Amazon S3.The data onAmazon S3 has been curated and does not require any additional transformations steps.The company is using a commercial business intelligence (BI) tool onAmazon EC2 to run queries against the Hadoop cluster and visualize the data.The company wants to reduce or eliminate the overhead costs associated with managing the Hadoop cluster and the BI tool.The company would like to move to a more cost-effective solution with minimal effort.The visualization is simple and requires performing some basic aggregation steps only.Which option will meet the company’s requirements?Read More →

A company hosts an application that uses several Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). During the initial startup of the EC2 instances, the EC2 instances run user data scripts to download critical content for the application from an Amazon S3 bucket.The EC2 instances are launching correctly. However, after a period of time, the EC2 instances are terminated with the following error message: “An instance was taken out of service in response to an ELB system health check failure.” EC2 instances continue to launch and be terminated because of Auto Scaling events in an endless loop.The only recent change to the deployment is that the company added a large amount of critical content to the S3 bucket. The company does not want to alter the user data scripts in production.What should a solutions architect do so that the production environment can deploy successfully?Read More →

A company has a High Performance Computing (HPC) cluster in its on-premises data center, which runs thousands of jobs in parallel for one week every month, processing petabytes of images.The images are stored on a network file server, which is replicated to a disaster recovery site.The on-premises data center has reached capacity and has started to spread the jobs out over the course of the month in order to better utilize the cluster, causing a delay in the job completion.The company has asked its Solutions Architect to design a cost-effective solution on AWS to scale beyond the current capacity of 5,000 cores and 10 petabytes of data.The solution must require the least amount of management overhead and maintain the current level of durability.Which solution will meet the company’s requirements?Read More →

A company is developing a latency-sensitive application.Part of the application includes several AWS Lambda functions that need to initialize as quickly as possible.The Lambda functions are written in Java and contain initialization code outside the handlers to load libraries, initialize classes, and generate unique IDs.Which solution will meet the startup performance requirement MOST cost-effectively?Read More →

A company has a serverless multi-tenant content management system on AWS.The architecture contains a web-based front end that interacts with an AmazonAPI Gateway API that uses a custom AWS Lambda authorizer.The authorizer authenticates a user to its tenant ID and encodes the information in a JSON WebToken (JWT) token.After authentication, each API call through API Gateway targets a Lambda function that interacts with a single Amazon DynamoDB table to fulfill requests.To comply with security standards, the company needs a stronger isolation between tenants.The company will have hundreds of customers within the first year.Which solution will meet these requirements with the LEAST operational overhead?Read More →
