PAS-C01 Technology Practice Question
Which TWO of the following are required components for an SAP HANA scale-out deployment on AWS that uses shared storage for /hana/shared? (Choose two.)
⚠ Common exam trap
A common mix-up: candidates assume Amazon EBS with multi-attach is a valid shared storage option for SAP HANA, but multi-attach is not supported for SAP HANA scale-out, and they may overlook that both EFS and FSx for ONTAP are the only AWS-managed NFS solutions that meet SAP's certification requirements for /hana/shared.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon EFS file system
Amazon EFS is required for an SAP HANA scale-out deployment on AWS that uses shared storage for /hana/shared because it provides a fully managed, POSIX-compliant NFS file system that can be mounted concurrently across multiple EC2 instances. SAP HANA scale-out nodes require a shared file system for /hana/shared to exchange configuration and log data, and EFS supports the necessary NFSv4 protocol with the required throughput and latency characteristics for this workload.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Amazon EFS file system
Why this is correct
EFS provides NFS shared storage.
- ✗
EC2 instance store
Why it's wrong here
Instance store is ephemeral and not shared.
- ✗
Amazon S3 bucket
Why it's wrong here
S3 is object storage, not a file system.
- ✓
Amazon FSx for NetApp ONTAP
Why this is correct
FSx for ONTAP provides NFS shared storage.
- ✗
Amazon EBS volume
Why it's wrong here
EBS is block storage attached to one instance.
