PAS-C01 Technology Practice Question
A company is deploying SAP NetWeaver on AWS and needs to configure high availability for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). The solution must use AWS native services. Which TWO actions should be taken?
⚠ Common exam trap
Watch out — candidates often assume a load balancer (like ALB) is the standard AWS high availability solution, but for stateful SAP services requiring a fixed IP address, Elastic IP reassignment is the correct AWS-native approach, not a 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
✓
Associate an Elastic IP address with the active ASCS instance using a script.
An Elastic IP address can be programmatically reassigned to the standby ASCS instance using a script (e.g., AWS CLI or custom automation) during a failover event. This provides a stable virtual IP address that clients use to connect to the active ASCS, meeting the high availability requirement without relying on a load balancer, which is not suitable for SAP Central Services due to its stateful nature and the need for a fixed IP address.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Associate an Elastic IP address with the active ASCS instance using a script.
Why this is correct
Elastic IP can be moved during failover to provide a stable endpoint.
- ✗
Place an Application Load Balancer in front of the ASCS instances.
Why it's wrong here
ALB does not support ASCS protocols.
- ✗
Set up AWS Direct Connect for redundant connectivity.
Why it's wrong here
Direct Connect is for network connectivity, not for application failover.
- ✗
Deploy AWS Global Accelerator for failover.
Why it's wrong here
Global Accelerator is for traffic routing but not typical for ASCS.
- ✓
Use Amazon Route 53 with health checks and failover routing policy.
Why this is correct
Route 53 can route traffic to the active ASCS instance.
