How can the user save costs?

A user is running a MySQL RDS instance. The user will not use the DB for the next 3 months. How can the user save
costs?

A.
Pause the RDS activities from CLI until it is required in the future

B.
Stop the RDS instance

C.
Create a snapshot of RDS to launch in the future and terminate the instance now

D.
Change the instance size to micro

Explanation:
The RDS instances unlike the AWS EBS backed instances cannot be stopped or paused. The user needs to take the
final snapshot, terminate the instance and launch a new instance in the future from that snapshot.
