Can Provisioned IOPS be used on RDS instances launched in a VPC?

A. Yes, they can be used only with Oracle based instances.
B. Yes, they can be used for all RDS instances.
C. No
D. Yes, they can be used only with MySQL based instances.

Correct Answer: B

Explanation:

Explanation: The basic building block of Amazon RDS is the DB instance. DB instance storage comes in three types: Magnetic, General Purpose (SSD), and Provisioned IOPS (SSD). When you buy a server, you get CPU, memory, storage, and IOPS, all bundled together. With Amazon RDS, these are split apart so that you can scale them independently. So, for example, if you need more CPU, less IOPS, or more storage, you can easily allocate them.
