PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is running SAP NetWeaver on AWS and wants to implement a high-availability solution for the SAP Central Services (ASCS). Which AWS service can be used to manage the virtual IP address for failover?
⚠ Common exam trap
Candidates often assume a floating IP (Elastic IP) or a load balancer is required for SAP ASCS VIP failover, but AWS DNS-based failover with Route 53 is the recommended and supported method for SAP on AWS, avoiding the limitations of layer 2 networking in the cloud.

Correct answer & explanation
✓
Amazon Route 53 with failover routing
Amazon Route 53 with failover routing is the correct choice because it can manage a virtual IP address (VIP) for SAP Central Services (ASCS) failover by using DNS health checks to detect ASCS failure and automatically update the DNS record to point to the healthy secondary instance. This aligns with the SAP on AWS high-availability pattern where a DNS-based VIP is preferred over traditional floating IPs, as AWS does not support layer 2 VIP failover across Availability Zones.
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 Route 53 with failover routing
Why this is correct
Route 53 failover routing can redirect clients to the secondary ASCS.
- ✗
AWS Global Accelerator
Why it's wrong here
Global Accelerator is for global traffic, not typically for ASCS.
- ✗
Elastic Load Balancer (ELB)
Why it's wrong here
ELB is for HTTP traffic, not for SAP ASCS.
- ✗
Elastic IP address reassignment
Why it's wrong here
Elastic IP can be moved but requires automation; Route 53 is more common.
