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.
An SAP administrator needs to configure high availability for SAP NetWeaver AS ABAP. They plan to use AWS services. Which combination of services is required?
Amazon EFS and Pacemaker on EC2
EFS provides shared storage; Pacemaker manages clustering.
AWS Global Accelerator and Auto Scaling
Why wrong: Not suitable for NetWeaver HA.
Elastic Load Balancing and Amazon Route 53
Why wrong: Need shared storage and clustering.
Amazon EBS Multi-Attach volumes
Why wrong: EBS Multi-Attach not supported across AZs.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon EFS and Pacemaker on EC2
Option A is correct because SAP NetWeaver AS ABAP high availability on AWS requires shared storage for the /sapmnt and /usr/sap/trans directories, which Amazon EFS provides via NFSv4, and a cluster manager like Pacemaker on EC2 to orchestrate failover between the primary and secondary application servers. This combination ensures that the SAP central services (ASCS and ERS) can fail over seamlessly in the event of an instance or availability zone failure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse general AWS HA services (like ELB or Auto Scaling) with the specific shared-storage and cluster-manager requirements of SAP NetWeaver AS ABAP, leading them to overlook the necessity of a cluster filesystem (EFS) and a cluster resource manager (Pacemaker).
Detailed technical explanation
Under the hood, Pacemaker uses STONITH (Shoot The Other Node In The Head) fencing via AWS APIs to ensure that a failed node cannot corrupt shared data, while Amazon EFS provides a fully managed NFSv4.1 file system that supports the required locking mechanisms (e.g., fcntl locks) for SAP transport directories. In a real-world scenario, if the primary ASCS instance in us-east-1a fails, Pacemaker triggers a failover to the standby in us-east-1b, remounting EFS and starting the SAP services within minutes, which is critical for maintaining SAP system availability during planned or unplanned downtime.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
