A company is implementing an application on Amazon EC2 instances.The application needs to process incoming transactions.When the application detects a transaction that is not valid, the application must send a chat message to the company’s support team.To send the message, the application needs to retrieve the access token to authenticate by using the chat API.A developer needs to implement a solution to store the access token.The access token must be encrypted at rest and in transit.The access token must also be accessible from other AWS accounts.Which solution will meet these requirements with the LEAST management overhead?Read More →

A developer is writing an application that will retrieve sensitive data from a third-party system.The application will format the data into a PDF file.The PDF file could be more than 1 MB.The application will encrypt the data to disk by using AWS Key Management Service (AWS KMS).The application will decrypt the file when a user requests to download it.The retrieval and formatting portions of the application are complete.The developer needs to use the GenerateDataKey API to encrypt the PDF file so that the PDF file can be decrypted later.The developer needs to use an AWS KMS symmetric customer managed key for encryption.Which solutions will meet these requirements?Read More →

A developer is migrating an application to Amazon Elastic Kubernetes Service (Amazon EKS).The developer migrates the application to Amazon Elastic Container Registry (Amazon ECR) with an EKS cluster.As part of the application migration to a new backend, the developer creates a new AWS account.The developer makes configuration changes to the application to point the application to the new AWS account and to use new backend resources.The developer successfully tests the changes within the application by deploying the pipeline.The Docker image build and the pipeline deployment are successful, but the application is still connecting to the old backend.The developer finds that the application’s configuration is still referencing the original EKS cluster and not referencing the new backend resources.Which reason can explain why the application is not connecting to the new resources?Read More →
