Answer: Change the volume type of the existing gp2 volumes to gp3. Enter new values for volume size, IOPS, and throughput.
Option C is CORRECT because changing the volume type of the existing gp2 volumes to gp3 directly allows for a seamless upgrade without the need to detach and reattach volumes or transfer data manually. This method provides the least operational overhead as it leverages the built-in capability of AWS to change the volume type in place, ensuring no data loss and minimal disruption to the EC2 instances.

Question 19/60
A company is planning to upgrade its Amazon Elastic Block Store (Amazon EBS) General Purpose SSD storage from gp2 to gp3. The company wants to prevent any interruptions in its Amazon EC2 instances that will cause data loss during the migration to the upgraded storage.
Which solution will meet these requirements with the LEAST operational overhead?
A
Create snapshots of the gp2 volumes. Create new gp3 volumes from the snapshots. Attach the new gp3 volumes to the EC2 instances.
B
Create new gp3 volumes. Gradually transfer the data to the new gp3 volumes. When the transfer is complete, mount the new gp3 volumes to the EC2 instances to replace the gp2 volumes.
C
Change the volume type of the existing gp2 volumes to gp3. Enter new values for volume size, IOPS, and throughput.
D
Use AWS DataSync to create new gp3 volumes. Transfer the data from the original gp2 volumes to the new gp3 volumes.
