An online retailer needs to regularly process large product catalogs, which are handled in batches.These are sent out to be processed by people using theAmazon Mechanical Turk service, but the retailer has asked its Solutions Architect to design a workflow orchestration system that allows it to handle multiple concurrent Mechanical Turk operations, deal with the result assessment process, and reprocess failures.Which of the following options gives the retailer the ability to interrogate the state of every workflow with the LEAST amount of implementation effort?Read More →

A company has a web application that securely uploads pictures and videos to an Amazon S3 bucket.The company requires that only authenticated users are allowed to post content.The application generates a presigned URL that is used to upload objects through a browser interface.Most users are reporting slow upload times for objects larger than 100 MB.What can a solutions architect do to improve the performance of these uploads while ensuring only authenticated users are allowed to post content?Read More →

A company runs a three-tier application in AWS.Users report that the application performance can vary greatly depending on the time of day and functionality being accessed.The application includes the following components:✑ Eight t2.large front-end web servers that serve static content and proxy dynamic content from the application tier.✑ Four t2.large application servers.✑ One db.m4.large Amazon RDS MySQL Multi-AZ DB instance.Operations has determined that the web and application tiers are network constrained.Which of the following is a cost effective way to improve application performance? (Choose two.)Read More →

A company recently migrated a web application from an on-premises data center to the AWS Cloud.The web application infrastructure consists of an Amazon CloudFront distribution that routes to an Application Load Balancer (ALB), with Amazon Elastic Container Service (Amazon ECS) to process requests.A recent security audit revealed that the web application is accessible by using both CloudFront and ALB endpoints.However, the company requires that the web application must be accessible only by using the CloudFront endpoint.Which solution will meet this requirement with the LEAST amount of effort?Read More →

A company’s application is increasingly popular and experiencing latency because of high volume reads on the database server.The service has the following properties:✑ A highly available REST API hosted in one region using Application Load Balancer (ALB) with auto scaling.✑ A MySQL database hosted on an Amazon EC2 instance in a single Availability Zone.The company wants to reduce latency, increase in-region database read performance, and have multi-region disaster recovery capabilities that can perform a live recovery automatically without any data or performance loss (HA/DR).Which deployment strategy will meet these requirements?Read More →

A company is deploying a distributed in-memory database on a fleet of Amazon EC2 instances.The fleet consists of a primary node and eight worker nodes.The primary node is responsible for monitoring cluster health, accepting user requests, distributing user requests to worker nodes, and sending an aggregate response back to a client.Worker nodes communicate with each other to replicate data partitions.The company requires the lowest possible networking latency to achieve maximum performance.Which solution will meet these requirements?Read More →

A company is migrating mobile banking applications to run on Amazon EC2 instances in a VPC.Backend service applications run in an on-premises data center.The data center has an AWS Direct Connect connection into AWS.The applications that run in the VPC need to resolve DNS requests to an on-premises ActiveDirectory domain that runs in the data center.Which solution will meet these requirements with the LEAST administrative overhead?Read More →

A company is planning to migrate its on-premises transaction-processing application to AWS.The application runs inside Docker containers that are hosted on VMs in the company’s data center.The Docker containers have shared storage where the application records transaction data.The transactions are time sensitive.The volume of transactions inside the application is unpredictable.The company must implement a low-latency storage solution that will automatically scale throughput to meet increased demand.The company cannot develop the application further and cannot continue to administer the Docker hosting environment.How should the company migrate the application to AWS to 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 →
