A company is developing machine learning (ML) models on AWS.The company is developing the ML models as independent microservices.The microservices fetch approximately 1 GB of model data from Amazon S3 at startup and load the data into memory.Users access the ML models through an asynchronous API.Users can send a request or a batch of requests.The company provides the ML models to hundreds of users.The usage patterns for the models are irregular.Some models are not used for days or weeks.Other models receive batches of thousands of requests at a time.Which solution will meet these requirements?Read More →

A company stores user data in AWS.The data is used continuously with peak usage during business hours.Access patterns vary, with some data not being used for months at a time.A solutions architect must choose a cost-effective solution that maintains the highest level of durability while maintaining high availability.Which storage solution meets these requirements?Read More →

A company that primarily runs its application servers on premises has decided to migrate to AWS.The company wants to minimize its need to scale its Internet Small Computer Systems Interface (iSCSI) storage on premises.The company wants only its recently accessed data to remain stored locally.Which AWS solution should the company use to meet these requirements?Read More →

A company is launching a new application that requires a structured database to store user profiles, application settings, and transactional data.The database must be scalable with application traffic and must offer backups.Which solution will meet these requirements MOST cost-effectively?Read More →

A company is planning to migrate a legacy application to AWS.The application currently uses NFS to communicate to an on-premises storage solution to store application data.The application cannot be modified to use any other communication protocols other than NFS for this purpose.Which storage solution should a solutions architect recommend for use after the migration?Read More →

A company is testing an application that runs on an Amazon EC2 Linux instance.A single 500 GB Amazon Elastic Block Store (Amazon EBS) General Purpose SSO (gp2) volume is attached to the EC2 instance.The company will deploy the application on multiple EC2 instances in an Auto Scaling group.All instances require access to the data that is stored in the EBS volume.The company needs a highly available and resilient solution that does not introduce significant changes to the application’s code.Which solution will meet these requirements?Read More →

A company hosts its main public web application in one AWS Region across multiple Availability Zones.The application uses an Amazon EC2 Auto Scaling group and an Application Load Balancer (ALB).A web development team needs a cost-optimized compute solution to improve the company’s ability to serve dynamic content globally to millions of customers.Which solution will meet these requirements?Read More →

A company is moving its data and applications to AWS during a multiyear migration project.The company wants to securely access data on Amazon S3 from the company’s AWS Region and from the company’s on-premises location.The data must not traverse the internet.The company has established an AWS Direct Connect connection between its Region and its on-premises location.Which solution will meet these requirements?Read More →

A company is designing the architecture for a new mobile app that uses the AWS Cloud.The company uses organizational units (OUs) in AWS Organizations to manage its accounts.The company wants to tag Amazon EC2 instances with data sensitivity by using values of sensitive and nonsensitive.IAM identities must not be able to delete a tag or create instances without a tag.Which combination of steps will meet these requirements? (Choose two.)Read More →

A company is designing an event-driven order processing system.Each order requires multiple validation steps after the order is created.An idempotent AWS Lambda function performs each validation step.Each validation step is independent from the other validation steps.Individual validation steps need only a subset of the order event information.The company wants to ensure that each validation step Lambda function has access to only the information from the order event that the function requires.The components of the order processing system should be loosely coupled to accommodate future business changes.Which solution will meet these requirements?Read More →
