Use AWS Global Accelerator to distribute traffic
Why wrong: Global Accelerator improves routing, does not add application servers.
- B
Increase the instance size of the existing application server
Why wrong: Vertical scaling has limits and may cause downtime.
- C
Manually launch additional EC2 instances and configure them as application servers
Why wrong: Manual process is not scalable or automated.

How to Auto Scale SAP Application Tier on AWS
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 runs SAP NetWeaver on AWS and notices that the application server is experiencing high CPU utilization during peak hours. They need to scale out the SAP application tier. What is the best approach?

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
✓
Use an Auto Scaling group to automatically launch additional application servers and register them with the SAP application load balancer
Option D is correct because it provides an automated, elastic scaling solution for the SAP application tier. An Auto Scaling group can dynamically launch additional EC2 instances based on CPU utilization metrics and automatically register them with the SAP application load balancer, ensuring seamless distribution of incoming user traffic across multiple application servers without manual intervention.
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 often confuse scaling up (increasing instance size) with scaling out (adding more instances), or they assume manual provisioning is acceptable, missing the requirement for automation and elasticity in a production SAP environment.
Detailed technical explanation
How to think about this question
Under the hood, SAP application servers require registration with the SAP Message Server and the load balancer to handle user sessions. An Auto Scaling group integrated with a lifecycle hook can automate the SAP-specific registration process (e.g., using sapstartsrv or sapcontrol) when new instances are launched. In a real-world scenario, this approach ensures that during flash sales or month-end processing, the SAP landscape can scale out within minutes without manual overhead, while also automatically deregistering and terminating unhealthy instances.
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 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.

Same concept, more angles
2 more ways this is tested on PAS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is deploying SAP NetWeaver on AWS and needs to ensure that the SAP application servers can automatically scale based on CPU utilization. Which AWS service should they use?
easy- ✓ A.AWS Auto Scaling groups with CloudWatch alarms
- B.Amazon CloudWatch to monitor CPU and send alerts
- C.AWS Lambda to start and stop instances based on a schedule
- D.Elastic Load Balancing (ELB) with health checks
Why A: AWS Auto Scaling groups with CloudWatch alarms allow SAP application servers to automatically scale in or out based on CPU utilization thresholds. This is the correct approach because Auto Scaling groups can dynamically adjust the number of EC2 instances in response to CloudWatch metric alarms, which is essential for handling variable SAP workload demands without manual intervention.
Variation 2. An SAP system on AWS is experiencing high CPU utilization on the application server during peak hours. The SAP administrator wants to add a new application server instance to distribute the load. Which AWS service should be used to automatically register the new instance with the existing SAP system's load balancer?
hard- ✓ A.Auto Scaling group
- B.AWS Lambda
- C.Amazon SQS
- D.AWS CloudFormation
Why A: An Auto Scaling group can automatically launch new EC2 instances based on scaling policies (e.g., when CPU utilization exceeds a threshold) and, when configured with a lifecycle hook or a launch template that includes a user-data script, can register the new instance with the existing SAP system's load balancer (such as an Application Load Balancer or Classic Load Balancer). This ensures the new application server is automatically added to the load balancer target group, distributing incoming traffic without manual intervention.
