- A
An AWS ASW (Automated SAP Workload) service
Why wrong: No such service exists.
- B
Amazon EBS io1 volumes with Multi-Attach enabled for the database
Why wrong: Multi-Attach not supported for Linux; database should use separate volumes.
- C
A shared file system (e.g., Amazon EFS) for /sapmnt
Required for shared profile data.
- D
Each node must have its own /usr/sap/<SID>/ASCS and /usr/sap/<SID>/ERS directory on instance store
Why wrong: Instance store is ephemeral; EBS should be used.
- E
A virtual IP address (VIP) using Route53 health checks or the AWS CLI
Clients need a stable IP to connect to ASCS.
Question 1,047 of 1,733
What Two Things Are Required for a Successful SAP ASCS/ERS Failover on AWS?
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is designing a highly available SAP NetWeaver AS ABAP environment on AWS with a 2-node ASCS/ERS cluster. Which TWO of the following must be configured to ensure a successful failover? (Choose 2)
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) for /sapmnt
Option C is correct because SAP NetWeaver AS ABAP requires a shared /sapmnt directory accessible by both nodes in an ASCS/ERS cluster for consistent profile and configuration access during failover. Amazon EFS provides a POSIX-compliant, NFS-based shared file system that supports concurrent access from multiple EC2 instances across Availability Zones, which is essential for the cluster to function correctly. Option E is correct because a virtual IP address (VIP) is needed to provide a stable endpoint for clients to connect to the ASCS instance, regardless of which node is active. This can be achieved using Route53 health checks with failover routing or AWS CLI scripts that reassign the IP to the active node, ensuring seamless failover.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
A common pitfall in AWS SAP exams is thinking that instance store volumes are suitable for persistent SAP cluster directories, but they are ephemeral and will cause data loss on instance stop or termination, making them invalid for failover-critical components.
Detailed technical explanation
How to think about this question
In a 2-node ASCS/ERS cluster, the /sapmnt share is typically exported via NFS and must be highly available; Amazon EFS provides a managed NFS file system that automatically replicates data across multiple AZs, ensuring the share is accessible even if one AZ fails. The virtual IP address (VIP) is managed using a cluster resource manager (e.g., Pacemaker) that leverages Route53 health checks or AWS CLI to update DNS records, enabling clients to reconnect to the active node after failover without manual intervention.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
