A developer built an application by using multiple AWS Lambda functions.The Lambda functions must access dynamic configuration data at runtime.The data is maintained as a 6 KB JSON document in AWS AppConfig.The configuration data needs to be updated without requiring the redeployment of the application.The developer needs a solution that will give the Lambda functions access to the dynamic configuration data.What should the developer do to meet these requirements with the LEAST development effort?Read More →

A company is creating a continuous integration and continuous delivery (CI/CD) process by using AWS CodePipeline for its application on AWS.The CI/CD process will pull code from an AWS CodeCommit repository, create the application infrastructure by using AWS CloudFormation, deploy the frontend code to an Amazon S3 bucket that is configured for static website hosting, and deploy the application backend on an Amazon Elastic Container Service (Amazon ECS) cluster.A developer needs to create a new CodePipeline stage that creates the application infrastructure.Which solution will meet these requirements with the LEAST operational overhead?Read More →

A developer is running an application on an Amazon EC2 instance.When the application tries to read an Amazon S3 bucket, the application fails.The developer notices that the associated IAM role is missing the S3 read permission.The developer needs to give the application the ability to read the S3 bucket.Which solution will meet this requirement with the LEAST application disruption?Read More →

A company uses AWS CloudFormation to deploy an application that uses an Amazon API Gateway REST API with AWS Lambda function integration.The application uses Amazon DynamoDB for data persistence.The application has three stages: development, testing, and production.Each stage uses its own DynamoDB table.The company has encountered unexpected issues when promoting changes to the production stage.The changes were successful in the development and testing stages.A developer needs to route 20% of the traffic to the new production stage API with the next production release.The developer needs to route the remaining 80% of the traffic to the existing production stage.The solution must minimize the number of errors that any single customer experiences.Which approach should the developer take to meet these requirements?Read More →

A developer is writing a web application that is deployed on Amazon EC2 instances behind an internet-facing Application Load Balancer (ALB).The developer must add an Amazon CloudFront distribution in front of the ALB.The developer also must ensure that customer data from outside the VPC is encrypted in transit.Which combination of CloudFront configuration settings should the developer use to meet these requirements?
