- A
Use EBS Multi-Attach to share volumes between two EC2 instances
Why wrong: EBS Multi-Attach is rarely used in SAP HA designs because it has limitations with concurrent write access and requires cluster-aware file systems; common SAP HA architectures use shared storage like Amazon EFS or FSx for Lustre, making this option incorrect.
- B
Deploy the SAP application across multiple Availability Zones
Deploying across multiple Availability Zones provides redundancy and failover capability, which is a core HA principle for SAP systems.
- C
Run the SAP system on a single large instance
Why wrong: Running on a single large instance introduces a single point of failure and does not provide high availability.
- D
Use Amazon S3 for long-term backup storage
Why wrong: Using Amazon S3 for long-term backup is important for data protection and disaster recovery, but it is not a high availability consideration.
- E
Configure SAP HANA System Replication between primary and standby
SAP HANA System Replication between primary and standby instances ensures database high availability and automatic failover.
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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which THREE considerations are important when designing a SAP workload for high availability on AWS? (Select three.)
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
Deploy the SAP application across multiple Availability Zones
In SAP high availability on AWS, deploying across multiple Availability Zones (Option B) protects against AZ failures, and SAP HANA System Replication (Option E) ensures database failover. Option A (EBS Multi-Attach) is not a standard HA practice due to limitations with concurrent writes and cluster file system requirements; typical shared storage uses Amazon EFS or FSx. Option D (S3 for backup) is a data protection strategy, not an HA component. Option C (single large instance) provides no redundancy, thus is not HA.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse high availability design (which requires redundancy across instances and AZs) with backup strategies (S3), leading them to select Option D instead of recognizing that backup storage is a data protection concern, not an HA architecture component.
Detailed technical explanation
How to think about this question
EBS Multi-Attach uses a SCSI-3 Persistent Reservation protocol to coordinate concurrent access from multiple EC2 instances, ensuring data consistency for cluster-aware applications like SAP ENSA2. In a real-world SAP deployment, you would pair Multi-Attach with a Pacemaker cluster to manage failover of the ASCS instance across two EC2 instances in the same AZ, while SAP HANA System Replication (Option E) handles cross-AZ failover for the database layer.
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 |
