PAS-C01 Design of SAP Workloads on AWS Practice Question
Which THREE of the following are valid considerations for designing SAP workloads on AWS to achieve high availability within a single AWS Region? (Choose three.)
⚠ Common exam trap
The PAS-C01 exam often tests the misconception that ENSA2 requires a load balancer for replication traffic, but in reality, ENSA2 uses direct peer-to-peer communication between ASCS and ERS instances without any intermediate load balancer.
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 a cluster with a shared file system (e.g., Amazon EFS or FSx) for SAP ASCS
SAP ASCS (ABAP Central Services) requires a shared file system for the global transport directory and instance profiles to enable failover between cluster nodes. Amazon EFS or FSx for NetApp ONTAP provide the necessary NFS-based shared storage that supports the SAP enqueue replication and message server services during a failover event.
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 AWS Network Load Balancer (NLB) for SAP Enqueue Replication 2 (ENSA2)
Why it's wrong here
ENSA2 uses a built-in mechanism, not an NLB.
- ✗
Use HANA scale-out with HSR across two nodes for high availability
Why it's wrong here
Scale-out HSR is not a typical HA setup; scale-up is used.
- ✓
Use a cluster with a shared file system (e.g., Amazon EFS or FSx) for SAP ASCS
Why this is correct
ASCS can be made highly available with a clustered file system.
- ✓
Use Elastic Network Interface (ENI) failover for the SAP application server floating IP
Why this is correct
ENI failover can be used for SAP application server HA.
- ✓
Implement HANA System Replication (HSR) with automatic failover using a third instance as a quorum
Why this is correct
HSR requires a third site to avoid split-brain.

| 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 |
