PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 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?
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.
This provides high availability with failover across AZs.
B
Use Amazon S3 to store the ASCS configuration and launch a single EC2 instance with an Auto Scaling group.
Why wrong: S3 is not a suitable shared file system for ASCS.
C
Deploy ASCS on a single EC2 instance in one Availability Zone with an EBS volume snapshot for recovery.
Why wrong: A single AZ does not provide high availability.
D
Use Amazon RDS for SAP Central Services running in a Multi-AZ configuration.
Why wrong: Amazon RDS cannot host SAP Central Services.
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.
Option A is correct because 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.
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
The trap here is that candidates 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.
Detailed technical explanation
How to think about this question
SAP ASCS uses an enqueue replication server (ERS) to replicate lock tables, and the shared file system must support NFS v4 with Kerberos for secure access. FSx for NetApp ONTAP provides consistent snapshot capabilities and can be mounted simultaneously across AZs, while the Elastic IP address acts as the virtual IP (VIP) that is reassigned to the standby EC2 instance during failover. In a real-world scenario, the cluster manager (e.g., Pacemaker with SUSE or Red Hat) monitors the ASCS service and triggers the VIP reassignment and file system remount.
KKey Concepts to Remember

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 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.
