Explanation:
Using io2 for critical data files provides sustained, low-latency performance with high predictable IOPS. Switching gp2 to gp3 allows setting IOPS and throughput independently, reducing cost while maintaining performance. EFS is network file system adding latency. FSx for Lustre is for HPC. st1 is for sequential throughput and poor for random I/O.
Ultimate access to all questions.

Amazon EFS
B
Use io2 for critical data files
C
Switch gp2 to gp3 and set IOPS/throughput independently
D
Amazon FSx for Lustre
E
