PAS-C01 Design of SAP Workloads on AWS Practice Question
A company runs SAP on AWS and wants to implement a high-availability (HA) solution for SAP Central Services (ASCS/ERS) using Amazon EC2 instances. Which AWS service is essential for managing the virtual IP address (VIP) required for the HA cluster?
⚠ Common exam trap
Many exam-takers assume a traditional on-premises VIP (e.g., using a floating IP with ARP) is required, but AWS does not support that, so the correct answer is a DNS-based solution like Route 53, not a load balancer or accelerator.

Correct answer & explanation
✓
Amazon Route 53
Amazon Route 53 is essential for managing the virtual IP address (VIP) required for the SAP Central Services (ASCS/ERS) HA cluster because it provides DNS-based failover. When the active ASCS instance fails, the HA cluster updates a Route 53 DNS record to point to the standby instance's IP address, effectively migrating the VIP. This allows clients to reconnect using the same DNS name without needing an elastic IP or a network-level VIP, which is not natively supported in AWS for this use case.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Global Accelerator
Why it's wrong here
Global Accelerator is used for global traffic management, not for HA VIP within a region.
- ✓
Amazon Route 53
Why this is correct
Route 53 can provide failover routing with health checks to redirect traffic to the standby ASCS instance.
- ✗
AWS WAF
Why it's wrong here
WAF is a web application firewall, not a routing service.
- ✗
Application Load Balancer
Why it's wrong here
ALB is not used for ASCS VIP; SAP HA typically uses a floating IP managed by the cluster.
