A data-processing application runs on an i3.large EC2 instance with a single 100 GB EBS gp2 volume. The
application stores temporary data in a small database (less than 30 GB) located on the EBS root volume.
The application is struggling to process the data fast enough, and a Solutions Architect has determined
that the I/O speed of the temporary database is the bottleneck.
What is the MOST cost-efficient way to improve the database response times?
A. Enable EBS optimization on the instance and keep the temporary files on the existing volume.
B. Move the temporary database onto instance storage.
C. Put the temporary database on a new 50-GB EBS io1 volume with a 3-K lOPS provision.
D. Put the temporary database on a new 50-GB EBS gp2 volume.
