A company’s order system sends requests from clients to Amazon EC2 instances.The EC2 instances process the orders and then store the orders in a database on Amazon RDS.Users report that they must reprocess orders when the system fails.The company wants a resilient solution that can process orders automatically if a system outage occurs.What should a solutions architect do to meet these requirements?Read More →

A company is preparing a new data platform that will ingest real-time streaming data from multiple sources.The company needs to transform the data before writing the data to Amazon S3.The company needs the ability to use SQL to query the transformed data.Which solutions will meet these requirements? (Choose two.)Read More →

A company wants to move a multi-tiered application from on premises to the AWS Cloud to improve the application’s performance.The application consists of application tiers that communicate with each other by way of RESTful services.Transactions are dropped when one tier becomes overloaded.A solutions architect must design a solution that resolves these issues and modernizes the application.Which solution meets these requirements and is the MOST operationally efficient?Read More →

A company is migrating a distributed application to AWS.The application serves variable workloads.The legacy platform consists of a primary server that coordinates jobs across multiple compute nodes.The company wants to modernize the application with a solution that maximizes resiliency and scalability.How should a solutions architect design the architecture to meet these requirements?Read More →

A company needs to connect its on-premises data center network to a new VPC.The data center network has a 100 Mbps symmetrical internet connection.An application that is running on premises will transfer multiple gigabytes of data each day.The application will use an Amazon Kinesis Data Firehose delivery stream for processing.What should a solutions architect recommend for maximum performance?Read More →

A company that recently started using AWS establishes a Site-to-Site VPN between its on-premises datacenter and AWS.The company’s security mandate states that traffic originating from on premises should stay within the company’s private IP space when communicating with an Amazon Elastic Container Service(Amazon ECS) cluster that is hosting a sample web application.Which solution meets this requirement?Read More →

A company runs a public three-tier web application in a VPC.The application runs on Amazon EC2 instances across multiple Availability Zones.The EC2 instances that run in private subnets need to communicate with a license server over the internet.The company needs a managed solution that minimizes operational maintenance.Which solution meets these requirements?Read More →

A company has an event-driven application that invokes AWS Lambda functions up to 800 times each minute with varying runtimes.The Lambda functions access data that is stored in an Amazon Aurora MySQL DB cluster.The company is noticing connection timeouts as user activity increases.The database shows no signs of being overloaded.CPU, memory, and disk access metrics are all low.Which solution will resolve this issue with the LEAST operational overhead?Read More →

A company hosts an application on AWS.The application uses AWS Lambda functions and stores data in Amazon DynamoDB tables.The Lambda functions are connected to a VPC that does not have internet access.The traffic to access DynamoDB must not travel across the internet.The application must have write access to only specific DynamoDB tables.Which combination of steps should a solutions architect take to meet these requirements? (Choose two.)Read More →

A research company runs experiments that are powered by a simulation application and a visualization application.The simulation application runs on Linux and outputs intermediate data to an NFS share every 5 minutes.The visualization application is a Windows desktop application that displays the simulation output and requires an SMB file system.The company maintains two synchronized file systems.This strategy is causing data duplication and inefficient resource usage.The company needs to migrate the applications to AWS without making code changes to either application.Which solution will meet these requirements?Read More →
