A company is performing an AWS Well-Architected Framework review of an existing workload deployed on AWS.The review identified a public-facing website running on the same Amazon EC2 instance as a Microsoft Active Directory domain controller that was install recently to support other AWS services.A solutions architect needs to recommend a new design that would improve the security of the architecture and minimize the administrative demand on IT staff.What should the solutions architect recommend?Read More →

A solutions architect is designing storage for a high performance computing (HPC) environment based on Amazon Linux.The workload stores and processes a large amount of engineering drawings that require shared storage and heavy computing.Which storage option would be the optimal solution?Read More →

A company hosts a static website on-premises and wants to migrate the website to AWS.The website should load as quickly as possible for users around the world.The company also wants the most cost-effective solution.What should a solutions architect do to accomplish this?Read More →

A financial services company has a web application that serves users in the United States and Europe. The application consists of a database tier and a web server tier. The database tier consists of a MySQL database hosted in us-east-1. Amazon Route 53 geoproximity routing is used to direct traffic to instances in the closest Region. A performance review of the system reveals that European users are not receiving the same level of query performance as those in the UnitedStates.Which changes should be made to the database tier to improve performance?Read More →

An application runs on Amazon EC2 instances across multiple Availability Zones.The instances run in an Amazon EC2 Auto Scaling group behind an ApplicationLoad Balancer.The application performs best when the CPU utilization of the EC2 instances is at or near 40%.What should a solutions architect do to maintain the desired performance across all instances in the group?Read More →

A company’s website is using an Amazon RDS MySQL Multi-AZ DB instance for its transactional data storage.There are other internal systems that query this DB instance to fetch data for internal batch processing.The RDS DB instance slows down significantly when the internal systems fetch data.This impacts the website’s read and write performance, and the users experience slow response times.Which solution will improve the website’s performance?Read More →

A web application is deployed in the AWS Cloud.It consists of a two-tier architecture that includes a web layer and a database layer.The web server is vulnerable to cross-site scripting (XSS) attacks.What should a solutions architect do to remediate the vulnerability?Read More →

A solutions architect is designing an application for a two-step order process.The first step is synchronous and must return to the user with little latency.The second step takes longer, so it will be implemented in a separate component.Orders must be processed exactly once and in the order in which they are received.How should the solutions architect integrate these components?Read More →

A company has an application that uses overnight digital images of products on store shelves to analyze inventory data.The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB) and obtains the images from an Amazon S3 bucket for its metadata to be processed by worker nodes for analysis.A solutions architect needs to ensure that every image is processed by the worker nodes.What should the solutions architect do to meet this requirement in the MOST cost-efficient way?Read More →

A company runs an application on Amazon EC2 instances that are part of an Auto Scaling group.Traffic to the application increases substantially during business hours.A solutions architect needs to implement an Auto Scaling policy that addresses user latency concerns during periods of high traffic.The company does not want to provisions more compute than is necessary.What should the solutions architect do to meet these requirements?Read More →
