Actual exam question for Amazon's SOA-C02 exam

Question #: 115
Topic #: 4

A company runs hundreds of Amazon EC2 instances in a single AWS Region. Each EC2 instance has two attached 1 GiB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volumes. A critical workload is using all the available IOPS capacity on the EBS volumes.

According to company policy, the company cannot change instance types or EBS volume types without completing lengthy acceptance tests to validate that the company's applications will function properly. A SysOps administrator needs to increase the I/O performance of the EBS volumes as quickly as possible.

Which action should the SysOps administrator take to meet these requirements?

AIncrease the size of the 1 GiB EBS volumes.

BAdd two additional elastic network interfaces on each EC2 instance.

CTurn on Transfer Acceleration on the EBS volumes in the Region.

DAdd all the EC2 instances to a cluster placement group.

Show Suggested Answer

Suggested Answer: A

Increasing the size of the 1 GiB EBS volumes will increase the IOPS capacity of the volumes, which will improve the I/O performance of the EBS volumes. This option does not require any changes to the instance types or EBS volume types, so it can be done quickly without the need for lengthy acceptance tests to validate that the company's applications will function properly.
