A company runs a web application on a single Amazon EC2 instance.End users experience slow application performance during times of peak usage, when CPU utilization is consistently more than 95%.A user data script installs required custom packages on the EC2 instance.The process of launching the instance takes several minutes.The company is creating an Auto Scaling group that has mixed instance groups, varied CPUs, and a maximum capacity limit.The Auto Scaling group will use a launch template for various configuration options.The company needs to decrease application latency when new instances are launched during auto scaling.Which solution will meet these requirements?Read More →

A company is currently running a production workload on AWS that is very I/O intensive.Its workload consists of a single tier with 10 c4.8xlarge instances, each with 2 TB gp2 volumes.The number of processing jobs has recently increased, and latency has increased as well.The team realizes that they are constrained on the IOPS.For the application to perform efficiently, they need to increase the IOPS by 3,000 for each of the instances.Which of the following designs will meet the performance goal MOST cost effectively?Read More →

A company needs to improve the reliability of its ticketing application.The application runs on an Amazon Elastic Container Service (Amazon ECS) cluster.The company uses Amazon CloudFront to serve the application.A single ECS service of the ECS cluster is the CloudFront distribution’s origin.The application allows only a specific number of active users to enter a ticket purchasing flow.These users are identified by an encrypted attribute in their JSON Web Token (JWT).All other users are redirected to a waiting room module until there is available capacity for purchasing.The application is experiencing high loads.The waiting room module is working as designed, but load on the waiting room is disrupting the applications availability.This disruption is negatively affecting the application’s ticket sale transactions.Which solution will provide the MOST reliability for ticket sale transactions during periods of high load?Read More →

A company asks a solution architect to optimize the cost of a solution.The solution handles requests from multiple customers.The solution includes a multi-tier architecture that uses Amazon API Gateway, AWS Lambda, AWS Fargate, Amazon Simple Queue Service (Amazon SQS), and Amazon EC2.In the current setup, requests go through API Gateway to Lambda and either start a container in Fargate or push a message to an SQS queue.An EC2 Fleet provides EC2 instances that serve as workers for the SQS queue.The EC2 Fleet scales based on the number of items in the SQS queue.Which combination of steps should the solutions architect recommend to reduce cost the MOST? (Choose three.)Read More →

A company hosts an intranet web application on Amazon EC2 instances behind an Application Load Balancer (ALB).Currently, users authenticate to the application against an internal user database.The company needs to authenticate users to the application by using an existing AWS Directory Service for Microsoft Active Directory directory.All users with accounts in the directory must have access to the application.Which solution will meet these requirements?Read More →

An ecommerce website running on AWS uses an Amazon RDS for MySQL DB instance with General Purpose SSD storage.The developers chose an appropriate instance type based on demand, and configured 100 GB of storage with a sufficient amount of free space.The website was running smoothly for a few weeks until a marketing campaign launched.On the second day of the campaign, users reported long wait times and time outs.Amazon CloudWatch metrics indicated that both reads and writes to the DB instance were experiencing long response times.The CloudWatch metrics show 40% to 50% CPU and memory utilization, and sufficient free storage space is still available.The application server logs show no evidence of database connectivity issues.What could be the root cause of the issue with the marketing campaign?Read More →

A company that has multiple business units is using AWS Organizations with all features enabled.The company has implemented an account structure in which each business unit has its own AWS account.Administrators in each AWS account need to view detailed cost and utilization data for their account by using Amazon Athena.Each business unit can have access to only its own cost and utilization data.The IAM policies that govern the ability to set up AWS Cost and Usage Reports are in place.A central Cost and Usage Report that contains all data for the organization is already available in an Amazon S3 bucket.Which solution will meet these requirements with the LEAST operational complexity?Read More →
