A user is creating a PIOPS volume. What is the maximum ratio the user should configure
between PIOPS and the volume size?

A.
5

B.
10

C.
20

D.
30

Explanation:
Provisioned IOPS volumes are designed to meet the needs of I/O-intensive workloads,
particularly database workloads that are sensitive to storage performance and consistency in
random access I/O throughput. A provisioned IOPS volume can range in size from 10 GB to 1 TB
and the user can provision up to 4000 IOPS per volume.
The ratio of IOPS provisioned to the volume size requested can be a maximum of 30; for
example, a volume with 3000 IOPS must be at least 100 GB.
