[All AWS Certified Solutions Architect - Professional Questions]

A financial services company has an on-premises environment that ingests market data feeds from stock exchanges, transforms the data, and sends the data to an internal Apache Kafka cluster. Management wants to leverage AWS services to build a scalable and near-real-time solution with consistent network performance to provide stock market data to a web application.
Which steps should a solutions architect take to build the solution? (Choose three.)

A. Establish an AWS Direct Connect connection from the on-premises data center to AWS.
B. Create an Amazon EC2 Auto Scaling group to pull the messages from the on-premises Kafka cluster and use the Amazon Consumer Library to put the data into an Amazon Kinesis data stream.
C. Create an Amazon EC2 Auto Scaling group to pull the messages from the on-premises Kafka cluster and use the Amazon Kinesis Producer Library to put the data into a Kinesis data stream.
D. Create a WebSocket API in Amazon API Gateway, create an AWS Lambda function to process an Amazon Kinesis data stream, and use the @connections command to send callback messages to connected clients.
E. Create a GraphQL API in AWS AppSync, create an AWS Lambda function to process the Amazon Kinesis data stream, and use the @connections command to send callback messages to connected clients.
F. Establish a Site-to-Site VPN from the on-premises data center to AWS.

ACD, A is obvious because of consistency, B is wrong because there is no AWS library and D because @callback is a feature of Websocket API

@connections command for call back doesnt seem to be available in Appsync( but yes with API gateway) as it manages these constructs internally. Seeing this ACD is correct.

ACD is correct. E is incorrect because @connections to have the backend service connect back to the connected clients is not a feature of GraphQL API using AppSync.
