An application running on an Amazon EC2 instance requires a block storage volume that can deliver a sustained performance of $12,000 \text{ IOPS}$ and $350 \text{ MiB/s}$ of throughput. Which two Amazon EBS volume types can be configured to meet these requirements? (Select TWO.)

General Purpose SSD (gp3)Answer
Provisioned IOPS SSD (io2)Answer
C
General Purpose SSD (gp2)
D
Throughput Optimized HDD (st1)
E
Cold HDD (sc1)

Answer

The application should use General Purpose SSD (gp3) and Provisioned IOPS SSD (io2) volumes because both types support provisioning throughput up to at least

1,000 \text{ MiB/s}

and IOPS up to at least

16,000 \text{ IOPS}

per volume, satisfying the required

12,000 \text{ IOPS}

and

350 \text{ MiB/s}

General Purpose SSD (gp3) and Provisioned IOPS SSD (io2) are the correct answers because both volume types support the configuration of up to

1,000 \text{ MiB/s}

of throughput and at least

16,000 \text{ IOPS}

(

64,000 \text{ IOPS}

for io2) per volume, satisfying the application's requirement for

12,000 \text{ IOPS}

and

350 \text{ MiB/s}

of throughput.

Step-by-Step Solution

Analyze the workload's performance requirements.

The workload requires a block storage volume with

12,000 \text{ IOPS}

and

350 \text{ MiB/s}

of throughput.

This establishes the minimum performance baseline that any selected storage volume must support.

Evaluate General Purpose SSD volumes.

General Purpose SSD (gp3) volumes can be provisioned with up to

16,000 \text{ IOPS}

and

1,000 \text{ MiB/s}

throughput. General Purpose SSD (gp2) volumes have a maximum throughput limit of

250 \text{ MiB/s}

This identifies that gp3 is capable of meeting both performance metrics, while gp2 falls short on throughput.

Evaluate Provisioned IOPS SSD and HDD-based volumes.

Provisioned IOPS SSD (io2) volumes support up to

64,000 \text{ IOPS}

and

1,000 \text{ MiB/s}

throughput. HDD-based volumes (st1 and sc1) are capped at

500 \text{ IOPS}

and

250 \text{ IOPS}

respectively.

This confirms io2 is a valid option, whereas st1 and sc1 cannot meet the IOPS requirements.
