PAS-C01 Migration Practice Question
During a migration of an SAP ERP system to AWS, the team notices that the SAP application performance is slow on the new EC2 instances. The instance type is correct for SAP certification. What is the most likely cause?

Correct answer & explanation
✓
EBS volumes are not provisioned with enough IOPS
Storage performance, specifically IOPS, often impacts SAP performance. Even if the instance type is correct, if the EBS volumes are not provisioned with sufficient IOPS, performance will suffer. Option D is correct. Option A (incorrect instance type) is not the issue. Option B (placement group) could be an issue but is less likely. Option C (security group) wouldn't cause performance issues.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Instances are in different placement groups
Why it's wrong here
Placement groups affect network latency, not necessarily performance.
- ✗
Incorrect EC2 instance type
Why it's wrong here
The instance type is correct per SAP certification.
- ✗
Security group rules are blocking traffic
Why it's wrong here
Security groups affect connectivity, not performance.
- ✓
EBS volumes are not provisioned with enough IOPS
Why this is correct
Insufficient IOPS leads to storage bottlenecks and slow performance.

Variation 1. During the migration of an SAP NetWeaver system, the team notices that the application server performance is degraded after migrating to AWS. The system uses AWS EBS volumes for storage. Which of the following is the most likely cause of the performance degradation?
medium- ✓ A.The EBS volumes have insufficient provisioned IOPS for the workload.
- B.The EBS volumes are using the wrong volume type.
- C.The EBS volumes are not encrypted.
- D.The EBS volumes are not EBS-optimized.
Why A: If EBS volumes are not provisioned with sufficient IOPS, the application server may experience performance degradation. EBS-optimized instances and appropriate volume types are important. EBS volumes are typically designed for durability, and encryption does not cause performance degradation.
