PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP administrator is troubleshooting a performance issue on an SAP NetWeaver system running on AWS. The system uses an Oracle database. The CPU utilization of the database server is consistently below 30%, but application response times are slow. Which THREE checks should the administrator perform to identify the bottleneck?
⚠ Common exam trap
Many candidates assume low CPU utilization means the system is not busy, overlooking that I/O wait, network latency, or database contention can cause slow responses without consuming CPU cycles.
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
✓
Use Amazon CloudWatch metrics to check network throughput and latency between the application and database servers.
High network latency or insufficient throughput between the application and database servers can cause slow response times even when CPU utilization is low. Amazon CloudWatch metrics such as NetworkIn, NetworkOut, and NetworkPacketsIn/Out can reveal congestion or bandwidth saturation, which is a common bottleneck in SAP NetWeaver deployments on AWS.
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 Amazon CloudWatch metrics to check network throughput and latency between the application and database servers.
Why this is correct
Network latency can cause slow responses.
- ✓
Check the EBS volume queue length and I/O wait times on the database server.
Why this is correct
High queue length indicates I/O bottleneck.
- ✓
Examine Oracle database wait events for enqueue and latch contention.
Why this is correct
Database locks can cause slow responses.
- ✗
Increase the number of CPU cores on the database server.
Why it's wrong here
CPU is already underutilized.
- ✗
Enable Amazon EBS Elastic Volumes to increase volume size dynamically.
Why it's wrong here
Volume size does not directly fix performance.
