PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is designing an SAP S/4HANA deployment on AWS. They want to ensure high availability for the central services (ASCS and ERS) across two Availability Zones. Which TWO of the following are required components for a typical SAP high availability setup on AWS? (Choose TWO.)
⚠ Common exam trap
It's easy for candidates to confuse the need for a shared file system (like EFS) with a database replication mechanism, but the question specifically asks for components required for central services (ASCS/ERS) HA, not the database layer.

Correct answer & explanation
✓
AWS Network Load Balancer to route traffic to the ASCS and ERS instances.
The AWS Network Load Balancer (NLB) is required to distribute traffic to the ASCS and ERS instances across two Availability Zones. It uses health checks to detect failures and reroute traffic to the healthy instance, ensuring that the SAP central services remain available even if one AZ fails. The NLB operates at Layer 4, preserving the source IP and supporting the necessary SAP protocols like the Message Server and Enqueue Replication.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon RDS Multi-AZ deployment for the SAP HANA database.
Why it's wrong here
SAP HANA is not supported on Amazon RDS; it runs on EC2.
- ✓
AWS Network Load Balancer to route traffic to the ASCS and ERS instances.
Why this is correct
NLB is used for SAP HA to manage virtual IPs and health checks.
- ✓
Amazon EFS file system mounted on both instances for shared /sapmnt.
Why this is correct
EFS provides a shared file system required for SAP HA.
- ✗
AWS Transit Gateway to connect the two Availability Zones.
Why it's wrong here
Transit Gateway is for network connectivity, not a mandatory HA component.
- ✗
AWS Global Accelerator to provide static anycast IP addresses.
Why it's wrong here
Global Accelerator is optional for performance, not required for HA.
