An enterprise is migrating its mission-critical SAP HANA environment to Azure Virtual Machines.
The SAP HANA database requires shared file storage that meets the following strict criteria:

- Support for NFS v4.1 protocol.
- Throughput of at least 4,000 MiB/s.
Which TWO actions should you take to provision the appropriate storage? (Select TWO)

- Support for NFS v4.1 protocol.
- Throughput of at least 4,000 MiB/s.
Which TWO actions should you take to provision the appropriate storage? (Select TWO)
Answer options:
A.
Provision an Azure Storage account with Premium file shares.
B.
Provision an Azure NetApp Files capacity pool.
C.
Create an NFS v4.1 volume within the capacity pool.
D.
Create an SMB 3.0 volume within the capacity pool.
E.
Provision an Azure Data Lake Storage Gen2 account.
How to approach this question
Identify the only Azure file storage service capable of bare-metal performance for SAP HANA (NetApp Files) and the correct protocol (NFS).
Full Answer
Provision an Azure NetApp Files capacity pool., Create an NFS v4.1 volume within the capacity pool.
Azure NetApp Files is an enterprise-class, high-performance, metered file storage service. It is the only Azure file service that provides the sub-millisecond latency and massive throughput required for SAP HANA data and log volumes. SAP HANA on Linux requires the NFS protocol (specifically v4.1 is supported and recommended).
Common mistakes
Selecting Premium Azure Files. While fast, Premium Files cannot match the bare-metal performance of NetApp Files required for SAP HANA.
