The answer is to add a second SAP application server in a different Availability Zone and configure load balancing. This action improves SAP application server HA on AWS without major changes because it introduces redundancy at the application tier while leaving the existing single-AZ database and architecture intact. By distributing user traffic across two AZs via a load balancer, the solution ensures continuous availability if one AZ fails, directly addressing the core requirement of improving high availability without a full architectural overhaul. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of the SAP application layer’s stateless nature and the minimal disruption required to achieve multi-AZ resilience. A common trap is overcomplicating the solution by suggesting database replication or instance resizing, but the key is that only the application server needs duplication. Memory tip: think “app layer, not data layer” — you only need to spread the stateless front-end, not the stateful back-end, to gain HA.
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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 workload on AWS uses a single Availability Zone deployment. The company wants to improve high availability without changing the existing architecture significantly. Which action should be taken?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add a second SAP application server in a different Availability Zone and configure load balancing.
Adding a second SAP application server in a different Availability Zone and configuring load balancing provides high availability by distributing traffic across multiple AZs, ensuring that if one AZ fails, the application remains accessible. This approach aligns with SAP's recommended architecture for multi-AZ deployments without requiring significant changes to the existing single-AZ setup, as it only adds an additional application tier instance and a load balancer.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 an Amazon EBS volume attached to multiple instances across AZs.
Why it's wrong here
EBS volumes are AZ-specific; cannot attach across AZs.
✓
Add a second SAP application server in a different Availability Zone and configure load balancing.
Why this is correct
This provides application tier HA across AZs.

✗
Increase the size of the EC2 instances to handle failover.
Why it's wrong here
Larger instances do not provide HA.
✗
Enable EBS Multi-Attach on the database volume.
Why it's wrong here
Multi-Attach is for clustered file systems, not HA.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse scaling (increasing instance size) with high availability, or assume EBS Multi-Attach works across Availability Zones, when in fact it is restricted to a single AZ and specific volume types.
Detailed technical explanation
How to think about this question
SAP application servers are stateless, allowing them to be placed behind a load balancer (e.g., AWS Application Load Balancer) across multiple AZs for seamless failover. The SAP Central Services (ASCS/ERS) typically require a separate high-availability mechanism (e.g., Pacemaker with EBS Multi-Attach or shared file system), but the question focuses on the application tier, where adding a second instance in a different AZ is the simplest path to multi-AZ resilience. In practice, this approach also requires updating the SAP transport routes and ensuring the load balancer health checks target the SAP application ports (e.g., 3200 for HTTP, 36xx for message server).

→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

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.
