The answer is Amazon FSx for NetApp ONTAP, which provides the required shared block storage for SAP HANA failover across Availability Zones. This service supports active/passive mode by allowing a single block-level volume to be concurrently accessed by EC2 instances in different AZs, meeting the low-latency, consistent storage needs of SAP S/4HANA. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of the distinction between block, file, and object storage for high-availability SAP architectures. A common trap is choosing Amazon EBS Multi-Attach, which only works within a single AZ, or Amazon EFS, which is file-level and not block-level. Remember: for cross-AZ block-level shared storage, think "ONTAP across the map" — FSx for NetApp ONTAP is the only service that delivers block-level concurrent access across zones for SAP HANA active/passive setups.
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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 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.
Option B is correct because Amazon EBS Multi-Attach allows a single EBS volume to be attached to multiple EC2 instances in the same Availability Zone, but for active/passive across AZs, shared EBS is not supported; the correct service is Amazon EFS, but EFS is file-level. For block-level concurrent access across AZs, Amazon FSx for NetApp ONTAP provides shared block storage. Option A is wrong because EBS Multi-Attach only works within a single AZ. Option C is wrong because FSx for Windows File Server is file-level. Option D is wrong because S3 is object storage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why this is correct
FSx for NetApp ONTAP supports shared block storage across AZs.
Related concept
Read the scenario before looking for a memorised answer.
✗
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
