Explanation:
When restoring EBS from snapshots, initial performance is lower until data is loaded (lazy loading). Fast Snapshot Restore (FSR) pre-warms the data, providing full performance immediately on restore, especially useful for Spot instances that start quickly.

EBS volumes restored from snapshots are performing below expected IOPS when EC2 Spot Instances start. How should this be resolved?
A
Configure fast snapshot restore (FSR) on the snapshots used.
B
Restore onto an unencrypted volume; encrypt after performance stabilizes.
C
Format EBS volumes as XFS before restoring snapshots.
D
Increase the Linux read-ahead buffer to 1 MiB.
