A developer is creating an application that includes an Amazon API Gateway REST API in the us-east-2 Region.The developer wants to use Amazon CloudFront and a custom domain name for the API.The developer has acquired an SSL/TLS certificate for the domain from a third-party provider.How should the developer configure the custom domain for the application?Read More →

A developer is creating a template that uses AWS CloudFormation to deploy an application.The application is serverless and uses Amazon API Gateway, Amazon DynamoDB, and AWS Lambda.Which AWS service or tool should the developer use to define serverless resources in YAML?Read More →

A developer wants to insert a record into an Amazon DynamoDB table as soon as a new file is added to an Amazon S3 bucket.Which set of steps would be necessary to achieve this?Read More →

A development team maintains a web application by using a single AWS CloudFormation template.The template defines web servers and an Amazon RDS database.The team uses the Cloud Formation template to deploy the Cloud Formation stack to different environments.During a recent application deployment, a developer caused the primary development database to be dropped and recreated.The result of this incident was a loss of data.The team needs to avoid accidental database deletion in the future.Which solutions will meet these requirements? (Choose two.)Read More →
