An application uses an Amazon RDS MySQL DB instance.The RDS database is becoming low on disk space.A solutions architect wants to increase the disk space without downtime.
Which solution meets these requirements with the LEAST amount of effort?
Enable storage auto scaling in RDS.
Increase the RDS database instance size.
Change the RDS database instance storage type to Provisioned IOPS.
Back up the RDS database, increase the storage capacity, restore the database and stop the previous instance.
Explanations:
Enabling storage auto scaling in RDS allows automatic increases in storage without downtime or manual effort.
Increasing the RDS instance size only affects CPU and memory, not storage capacity.
Changing storage type to Provisioned IOPS affects I/O performance but does not increase storage capacity.
Backing up, restoring, and stopping the previous instance involves downtime and complex manual steps.
From what I’ve heard, the answer is:
Enable storage auto scaling in RDS.
