PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is running SAP ERP on AWS and wants to ensure high availability for the SAP Central Services (ASCS) instance. Which AWS service should be used to achieve this?
⚠ Common exam trap
Candidates often confuse DNS-based services like Route 53 or Global Accelerator with the Layer 4 load balancing required for SAP ASCS VIP management, overlooking the NLB’s ability to provide a static IP and sub-second failover.
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
✓
Elastic Load Balancer (NLB)
For SAP ASCS high availability, AWS recommends using a Network Load Balancer (NLB) to manage the virtual IP address (VIP) required by SAP. The NLB handles the failover of the ASCS instance between two EC2 nodes by directing traffic to the active node, ensuring seamless client connectivity without relying on a floating IP or custom scripts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
EC2 Auto Scaling
Why it's wrong here
Auto Scaling is for scaling instances, not for ASCS failover.
- ✓
Elastic Load Balancer (NLB)
Why this is correct
Network Load Balancer can distribute traffic to multiple ASCS instances for HA.
- ✗
Amazon Route 53
Why it's wrong here
Route 53 can provide DNS failover but is not the primary service for ASCS HA.
- ✗
AWS Global Accelerator
Why it's wrong here
Global Accelerator improves performance but does not provide native HA for ASCS.
