Azure Blob Storage with NFS 3.0 enabled
D.
Azure Disk Storage (Ultra Disks)
How to approach this question
Identify the file storage service capable of extreme performance (450k IOPS) and NFS v4.1. Azure NetApp Files is purpose-built for this.
Full Answer
B.Azure NetApp Files✓ Correct
Azure NetApp Files
Azure NetApp Files (ANF) is an enterprise-class, high-performance, metered file storage service. It supports SMB and NFS (v3 and v4.1) protocols. Because it runs on bare-metal NetApp fleet in Azure datacenters, it provides sub-millisecond latency and massive throughput/IOPS (up to 460,000 IOPS), making it the recommended and certified shared file storage solution for SAP HANA in Azure. Azure Files Premium cannot reach this level of IOPS.
Common mistakes
Choosing Azure Files Premium. While it is a good service, it cannot meet the extreme 450,000 IOPS requirement.
