A company hosts an application that uses several Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). During the initial startup of the EC2 instances, the EC2 instances run user data scripts to download critical content for the application from an Amazon S3 bucket.The EC2 instances are launching correctly. However, after a period of time, the EC2 instances are terminated with the following error message: “An instance was taken out of service in response to an ELB system health check failure.” EC2 instances continue to launch and be terminated because of Auto Scaling events in an endless loop.The only recent change to the deployment is that the company added a large amount of critical content to the S3 bucket. The company does not want to alter the user data scripts in production.What should a solutions architect do so that the production environment can deploy successfully?Read More →

A company is developing a latency-sensitive application.Part of the application includes several AWS Lambda functions that need to initialize as quickly as possible.The Lambda functions are written in Java and contain initialization code outside the handlers to load libraries, initialize classes, and generate unique IDs.Which solution will meet the startup performance requirement MOST cost-effectively?Read More →

A company is running a serverless ecommerce application on AWS.The application uses Amazon API Gateway to invoke AWS Lambda Java functions.The Lambda functions connect to an Amazon RDS for MySQL database to store data.During a recent sale event, a sudden increase in web traffic resulted in poor API performance and database connection failures.The company needs to implement a solution to minimize the latency for the Lambda functions and to support bursts in traffic.Which solution will meet these requirements with the LEAST amount of change to the application?Read More →

A company plans to migrate many VMs from an on-premises environment to AWS.The company requires an initial assessment of the on-premises environment before the migration, a visualization of the dependencies between applications that run on the VMs, and a report that provides an assessment of the on-premises environment.To get this information, the company has initiated a Migration Evaluator assessment request.The company has the ability to install collector software in its on-premises environment without any constraintsWhich solution will provide the company with the required information with the LEAST operational overhead?Read More →

A company recently completed a successful proof of concept of Amazon WorkSpaces.A solutions architect needs to make the solution highly available across two AWS Regions.Amazon WorkSpaces is deployed in a failover Region, and a hosted zone is deployed in Amazon Route 53.What should the solutions architect do to configure high availability for the solution?Read More →

An ecommerce company runs an application on AWS.The application has an Amazon API Gateway API that invokes an AWS Lambda function.The data is stored in an Amazon RDS for PostgreSQL DB instance.During the company’s most recent flash sale, a sudden increase in API calls negatively affected the application’s performance.A solutions architect reviewed the Amazon CloudWatch metrics during that time and noticed a significant increase in Lambda invocations and database connections.The CPU utilization also was high on the DB instance.What should the solutions architect recommend to optimize the application’s performance?Read More →

A company wants to optimize AWS data-transfer costs and compute costs across developer accounts within the company’s organization in AWS Organizations.Developers can configure VPCs and launch Amazon EC2 instances in a single AWS Region.The EC2 instances retrieve approximately 1 TB of data each day from Amazon S3.The developer activity leads to excessive monthly data-transfer charges and NAT gateway processing charges between EC2 instances and S3 buckets, along with high compute costs.The company wants to proactively enforce approved architectural patterns for any EC2 instance and VPC infrastructure that developers deploy within the AWS accounts.The company does not want this enforcement to negatively affect the speed at which the developers can perform their tasks.Which solution will meet these requirements MOST cost-effectively?Read More →

A company has an application in the AWS Cloud.The application runs on a fleet of 20 Amazon EC2 instances.The EC2 instances are persistent and store data on multiple attached Amazon Elastic Block Store (Amazon EBS) volumes.The company must maintain backups in a separate AWS Region.The company must be able to recover the EC2 instances and their configuration within 1 business day, with loss of no more than 1 day’s worth of data.The company has limited staff and needs a backup solution that optimizes operational efficiency and cost.The company already has created an AWS CloudFormation template that can deploy the required network configuration in a secondary Region.Which solution will meet these requirements?Read More →

A company needs to migrate 60 on-premises legacy applications to AWS.The applications are based on the NET Framework and run on Windows.The company needs a solution that minimizes migration time and requires no application code changes.The company also does not want to manage the infrastructure.Which solution will meet these requirements?Read More →

A medical company is running a REST API on a set of Amazon EC2 instances.The EC2 instances run in an Auto Scaling group behind an Application Load Balancer (ALB).The ALB runs in three public subnets, and the EC2 instances run in three private subnets.The company has deployed an Amazon CloudFront distribution that has the ALB as the only origin.Which solution should a solutions architect recommend to enhance the origin security?Read More →
