PAS-C01 Migration Practice Question
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?
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
✓
The EBS volumes have insufficient provisioned IOPS for the workload.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The EBS volumes have insufficient provisioned IOPS for the workload.
Why this is correct
Insufficient IOPS can cause performance bottlenecks.
- ✗
The EBS volumes are using the wrong volume type.
Why it's wrong here
While possible, insufficient IOPS is a more common cause; volume type can be changed if needed.
- ✗
The EBS volumes are not encrypted.
Why it's wrong here
Encryption does not significantly impact performance.
- ✗
The EBS volumes are not EBS-optimized.
Why it's wrong here
EBS optimization is an instance feature, not a volume property. Most current instances support it.
