Q9 Single choice

A data engineer must maintain and monitor a data pipeline on AWS that processes streaming data from Internet of Things (IoT) devices. The pipeline uses Amazon Kinesis Data Streams to ingest data and Amazon Data Firehose to deliver data to an Amazon S3 bucket. The data engineer needs to monitor the health of the pipeline.

Which solution will meet these requirements with the LEAST operational effort?

A
Use Amazon CloudWatch Logs to manually review logs that are generated by Kinesis Data Streams and Firehose.
B
Configure Amazon CloudWatch alarms to monitor k ey metrics such as IncomingBytes, OutgoingBytes, and DeliveryToS3.Success for Kinesis Data Streams and Firehose
C
Use an AWS Lambda function to run daily checks on the status of the Kinesis Data Streams and Firehose.
Configure the Lambda function to use Amazon Simple Notification Service (Amazon SNS) to send notifications.
D
Use Amazon Managed Service for ApacheFlink to perform near real-time anomaly detection on the streaming data and to invoke alerts if unusual patterns are detected.
