PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is migrating its SAP NetWeaver system to AWS and wants to implement a high-availability architecture for the SAP Central Services (ASCS) and Enqueue Replication Server (ERS). Which TWO of the following are required components in a recommended AWS HA setup for ASCS and ERS?
⚠ Common exam trap
Many candidates confuse the need for a load balancer (Option B) with the floating IP mechanism, not realizing that SAP ASCS/ERS uses a virtual IP for active/passive failover rather than distributing traffic across multiple active instances.
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
✓
A shared file system (e.g., Amazon EFS) to store the SAP transport directory and global profile.
In an SAP NetWeaver high-availability architecture on AWS, a shared file system such as Amazon EFS is required to store the SAP transport directory and global profile. This ensures that both the ASCS and ERS instances can access consistent configuration and transport files, which is essential for failover and cluster operations. Without a shared file system, the instances would have divergent configurations, breaking the HA setup.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A shared file system (e.g., Amazon EFS) to store the SAP transport directory and global profile.
Why this is correct
ASCS and ERS require shared storage for transport directory.
- ✗
An Application Load Balancer to distribute traffic between ASCS and ERS instances.
Why it's wrong here
ASCS and ERS use a virtual IP, not a load balancer.
- ✓
A floating IP address (using Elastic IP or Route 53 health checks) to manage the ASCS virtual hostname.
Why this is correct
A virtual IP is required for ASCS failover.
- ✗
A read replica of the SAP HANA database to offload application traffic.
Why it's wrong here
Read replicas are for databases, not for ASCS/ERS.
- ✗
A secondary Windows Server Failover Cluster in a different Availability Zone.
Why it's wrong here
Linux Pacemaker is typically used on AWS for SAP HA.
