PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is migrating its SAP ERP system to AWS. The system requires high availability for the SAP Central Services (ASCS) instance. Which AWS architecture should be used to meet this requirement?
⚠ Common exam trap
Watch out — candidates often confuse SAP Central Services (ASCS) with a database service and incorrectly select Amazon RDS, or assume that a single-instance recovery solution like EBS snapshots meets high availability requirements, when in fact SAP ASCS requires a clustered architecture with shared storage and a floating IP.

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
✓
Use a multi-AZ deployment with Amazon FSx for NetApp ONTAP as a shared file system and place ASCS on two EC2 instances in different Availability Zones with an Elastic IP address.
SAP ASCS requires a highly available shared file system and a floating IP address for failover. Amazon FSx for NetApp ONTAP provides a highly available, NFS-based shared file system that supports the SAP transport and profile directories across Availability Zones. Placing two EC2 instances in different AZs with an Elastic IP address allows the ASCS instance to be failed over manually or via a cluster manager, meeting the high availability requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use a multi-AZ deployment with Amazon FSx for NetApp ONTAP as a shared file system and place ASCS on two EC2 instances in different Availability Zones with an Elastic IP address.
Why this is correct
This provides high availability with failover across AZs.
- ✗
Use Amazon S3 to store the ASCS configuration and launch a single EC2 instance with an Auto Scaling group.
Why it's wrong here
S3 is not a suitable shared file system for ASCS.
- ✗
Deploy ASCS on a single EC2 instance in one Availability Zone with an EBS volume snapshot for recovery.
Why it's wrong here
A single AZ does not provide high availability.
- ✗
Use Amazon RDS for SAP Central Services running in a Multi-AZ configuration.
Why it's wrong here
Amazon RDS cannot host SAP Central Services.
