PAS-C01 Technology Practice Question
A company is migrating its SAP system to AWS and needs to ensure high availability for the SAP Central Services (ASCS/ERS) instance. The solution must support automatic failover in case of an instance failure. Which AWS service should be used to manage the floating IP address required for the SAP high availability setup?
⚠ Common exam trap
A common mix-up: candidates assume Elastic IP addresses are the cloud equivalent of a floating IP, but Elastic IPs cannot be automatically reassigned based on health checks and require manual or scripted reattachment, making Route 53 DNS failover the correct AWS-native solution for SAP high availability.
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
✓
Amazon Route 53
Amazon Route 53 can be configured with health checks and DNS failover to manage the floating IP address required for SAP Central Services (ASCS/ERS) high availability. When the primary ASCS instance fails, Route 53 automatically updates DNS resolution to point to the secondary instance's IP address, enabling automatic failover without requiring a static floating IP.
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
Why this is correct
Route 53 with health checks and failover routing can manage floating IP via DNS.
- ✗
Elastic IP address
Why it's wrong here
Elastic IPs don't auto-failover without additional automation.
- ✗
Amazon CloudFront
Why it's wrong here
CloudFront is a CDN, not used for SAP HA failover.
- ✗
AWS Global Accelerator
Why it's wrong here
Global Accelerator provides static IPs but is not designed for SAP HA failover.
