They provide 99.8% durability with an AFR of 0.2%.
They are 2,000 times more reliable than typical commodity disk drives.
They offer 99.999% durability with an AFR of 0.001%, making them ideal for business-critical applications.
They support snapshots for point-in-time backups.

Correct Answer

They offer 99.999% durability with an AFR of 0.001%, making them ideal for business-critical applications.

Explanation

Amazon EBS io2 volumes are designed for high durability and reliability, providing 99.999% durability with an Annual Failure Rate (AFR) of just 0.001%. This makes them highly suitable for business-critical applications such as SAP HANA, Oracle, Microsoft SQL Server, and IBM DB2, which require maximum uptime.

 

While option B (being 2,000 times more reliable than commodity disks) and option D (supporting snapshots) are true, they are not the primary distinguishing benefit of io2. Similarly, option A describes other EBS volumes, not io2.
