PAS-C01 Design of SAP Workloads on AWS Practice Question
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?
⚠ Common exam trap
Many exam-takers confuse CloudWatch's monitoring and alerting capability with the actual scaling action, forgetting that CloudWatch alone cannot modify the instance count without an Auto Scaling group.
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
✓
AWS Auto Scaling groups with CloudWatch alarms
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
AWS Auto Scaling groups with CloudWatch alarms
Why this is correct
Auto Scaling groups can dynamically adjust capacity based on CPU utilization metrics from CloudWatch.
- ✗
Amazon CloudWatch to monitor CPU and send alerts
Why it's wrong here
CloudWatch monitors and alerts but does not automatically scale instances.
- ✗
AWS Lambda to start and stop instances based on a schedule
Why it's wrong here
Lambda can schedule start/stop but is not designed for dynamic scaling based on CPU.
- ✗
Elastic Load Balancing (ELB) with health checks
Why it's wrong here
ELB distributes incoming traffic but does not automatically scale instances.
