A Solutions Architect is designing a process that updates data in a database when any EC2 instance is launched, stopped, or terminated. This update must be performed as close to the EC2 change as possible. The Solutions Architect will use a CloudWatch Event Rule based on EC2 state changes.
Which solution should the Solutions Architect use to achieve this in the MOST cost-effective way?

• A.Create an Amazon Kinesis Data Stream Launch a Kinesis Data Stream worker to update the database
• B.Use an Amazon SQS queue Provision an EC2 instance to poll the queue and update the database
• C.Use an Amazon SQS queue Have a scheduled Lambda function read the queue and update the database.
• D.Create a Lambda function triggered by Amazon CloudWatch Events to directly update the database

A recently created startup built a three-tier web application. The front end has static content. The application layer is based on microservices. User data is stored as JSON documents that need to be accessed with low latency. The company expects regular traffic to be low during the first year, with peaks in traffic when it publicizes new features every month. The startup team needs to minimize operational overhead costs.
What should a solutions architect recommend to accomplish this?

• A.Use Amazon S3 static website hosting to store and serve the front end. Use AWS Elastic Beanstalk for the application layer. Use Amazon DynamoDB to store user data.
• B.Use Amazon S3 static website hosting to store and serve the front end. Use Amazon Elastic KubernetesService (Amazon EKS) for the application layer. Use Amazon DynamoDB to store user data.
• C.Use Amazon S3 static website hosting to store and serve the front end. Use Amazon API Gateway and AWS Lambda functions for the application layer. Use Amazon DynamoDB to store user data.
• D.Use Amazon S3 static website hosting to store and serve the front end. Use Amazon API Gateway and AWS Lambda functions for the application layer. Use Amazon RDS with read replicas to store user data.
