PAS-C01 Technology Practice Question
A company is deploying SAP NetWeaver on AWS and needs to set up high availability for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). The company uses a shared file system for the transport directory. Which components are essential for the HA setup? (Choose TWO.)
⚠ Common exam trap
Test-takers frequently confuse the HA requirements for SAP Central Services with those for the database layer, leading them to select Amazon RDS Multi-AZ (Option D) instead of focusing on the ASCS/ERS-specific components like the ALB and multi-AZ placement.
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
✓
An internal Application Load Balancer (ALB) to distribute traffic to the ASCS instance.
An internal Application Load Balancer (ALB) is essential because it provides a virtual IP address and health checks for the SAP ASCS instance. In a multi-AZ HA setup, the ALB routes client traffic to the active ASCS instance and automatically fails over to the standby instance if the primary fails, ensuring continuous access to SAP Central Services.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

An internal Application Load Balancer (ALB) to distribute traffic to the ASCS instance.
Why this is correct
ALB provides a virtual IP for ASCS.
- ✗
Both ASCS and ERS instances must run on the same EC2 instance.
