PAS-C01 Technology Practice Question
A company is designing a network architecture for SAP S/4HANA on AWS. The architecture must support high availability by distributing application servers across two Availability Zones. Which AWS service can provide automatic failover for the SAP central services (ASCS) instance?
⚠ Common exam trap
Candidates often assume a load balancer (ALB or NLB) is required for high availability, but SAP ASCS does not support load balancing across multiple active instances—it requires active/passive failover with a single virtual hostname, which DNS failover routing provides.
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 with DNS failover routing
Amazon Route 53 with DNS failover routing is correct because SAP ASCS (ABAP SAP Central Services) requires a virtual hostname that clients use to connect. Route 53 can monitor the health of the ASCS instance in the primary Availability Zone and automatically update DNS resolution to point to the standby ASCS instance in the secondary Availability Zone when a failure is detected. This provides the automatic failover needed for SAP central services without requiring a shared IP address across 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 DNS failover routing
Why this is correct
Route 53 can perform health checks and fail DNS to a standby ASCS in case of primary failure.
- ✗
AWS Direct Connect
Why it's wrong here
Direct Connect provides private connectivity from on-premises to AWS, not failover routing.
- ✗
Application Load Balancer (ALB)
Why it's wrong here
ALB can distribute traffic but does not manage SAP ASCS failover; SAP enqueue replication is needed.
- ✗
Amazon CloudFront
Why it's wrong here
CloudFront is a content delivery network, not suited for SAP application traffic.
