A company has an online shop that uses an Amazon API Gateway API, AWS Lambda functions, and an Amazon DynamoDB table provisioned with 900 RCUs.The API Gateway API receives requests from customers, and the Lambda functions handle the requests.Some of the Lambda functions read data from theDynamoDB table.During peak hours, customers are reporting timeout errors and slow performance.An investigation reveals that the Lambda functions that read the DynamoDB table occasionally time out.Amazon CloudWatch metrics show that the peak usage of the DynamoDB table is just below 900 RCUs.Which solution will resolve this issue MOST cost-effectively?Read More →

A company owns a chain of travel agencies and is running an application in the AWS Cloud.Company employees use the application to search for information about travel destinations.Destination content is updated four times each year.Two fixed Amazon EC2 instances serve the application.The company uses an Amazon Route 53 public hosted zone with a multivalue record of travel.example.com that returns the Elastic IP addresses for the EC2 instances.The application uses Amazon DynamoDB as its primary data store.The company uses a self-hosted Redis instance as a caching solution.During content updates, the load on the EC2 instances and the caching solution increases drastically.This increased load has led to downtime on several occasions.A solutions architect must update the application so that the application is highly available and can handle the load that is generated by the content updates.Which solution will meet these requirements?Read More →

A company has a requirement that only allows specially hardened AMIs to be launched into public subnets in a VPC, and for the AMIs to be associated with a specific security group.Allowing non-compliant instances to launch into the public subnet could present a significant security risk if they are allowed to operate.A mapping of approved AMIs to subnets to security groups exists in an Amazon DynamoDB table in the same AWS account.The company created an AWSLambda function that, when invoked, will terminate a given Amazon EC2 instance if the combination of AMI, subnet, and security group are not approved in theDynamoDB table.What should the Solutions Architect do to MOST quickly mitigate the risk of compliance deviations?Read More →

A company is currently in the design phase of an application that will need an RPO of less than 5 minutes and an RTO of less than 10 minutes.The solutions architecture team is forecasting that the database will store approximately 10 TB of data.As part of the design, they are looking for a database solution that will provide the company with the ability to fail over to a secondary Region.Which solution will meet these business requirements at the LOWEST cost?Read More →
