- A
Use Amazon FSx for NetApp ONTAP to provide a shared block storage volume accessible from both AZs.
FSx for NetApp ONTAP supports shared block storage across AZs.
- B
Use Amazon FSx for Windows File Server with a multi-AZ file system.
Why wrong: FSx for Windows File Server is file-level storage, not block-level.
- C
Use Amazon S3 as a shared block storage device.
Why wrong: S3 is object storage, not block storage.
- D
Use Amazon EBS Multi-Attach to attach a single EBS volume to both EC2 instances across AZs.
Why wrong: EBS Multi-Attach is limited to a single AZ.

PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is migrating an SAP S/4HANA system to AWS. The system requires high availability across two Availability Zones. Which AWS service should be used to attach a block-level storage volume that can be concurrently accessed by two EC2 instances in active/passive mode?
Answer choices
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
✓
Use Amazon FSx for NetApp ONTAP to provide a shared block storage volume accessible from both AZs.
Amazon FSx for NetApp ONTAP provides a shared block-level storage volume that can be concurrently accessed by multiple EC2 instances across different Availability Zones using the iSCSI protocol. In an active/passive SAP S/4HANA setup, this allows the passive instance to mount the same storage volume and take over if the active instance fails, meeting the high-availability requirement across two AZs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use Amazon FSx for NetApp ONTAP to provide a shared block storage volume accessible from both AZs.
Why this is correct
FSx for NetApp ONTAP supports shared block storage across AZs.
Related concept

- ✗
Use Amazon FSx for Windows File Server with a multi-AZ file system.
Why it's wrong here
FSx for Windows File Server is file-level storage, not block-level.
- ✗
Use Amazon S3 as a shared block storage device.
Why it's wrong here
S3 is object storage, not block storage.
- ✗
Use Amazon EBS Multi-Attach to attach a single EBS volume to both EC2 instances across AZs.
Why it's wrong here
EBS Multi-Attach is limited to a single AZ.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume Amazon EBS Multi-Attach can work across Availability Zones, but it is strictly limited to instances within the same AZ, making it unsuitable for multi-AZ high availability in SAP workloads.
Detailed technical explanation
How to think about this question
FSx for NetApp ONTAP leverages the NetApp ONTAP file system and exposes block storage via iSCSI or NVMe over TCP, allowing simultaneous read/write access from multiple clients with cluster-aware locking. In an SAP S/4HANA active/passive deployment, the shared volume must be accessible from both AZs to enable automatic failover, which FSx for NetApp ONTAP supports through its multi-AZ deployment option, providing synchronous replication between AZs and automatic failover of the storage endpoints.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
