B.
No
C.
Yes
D.
Only if Cloudwatch configured
Explanation:
See http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Events.html
Amazon RDS uses the Amazon Simple Notification Service (Amazon SNS) to provide notification when an
Amazon RDS event occurs. These notifications can be in any notification form supported by Amazon SNS for
an AWS region, such as an email, a text message, or a call to an HTTP endpoint.
Amazon RDS groups these events into categories that you can subscribe to so that you can be notified when
an event in that category occurs.
C is not correct because even though event is created by RDS you will not be alerted for it unless you configure
your subscription in SNS.
