PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is running SAP S/4HANA on AWS with a scale-out HANA configuration. The system is experiencing performance degradation during peak hours. Monitoring shows high network throughput on the HANA nodes. Which EC2 instance family is best suited to mitigate this?
⚠ Common exam trap
Many exam-takers assume any memory-optimized instance (like r5) is sufficient for SAP HANA, overlooking the specific network throughput and SAP certification requirements for scale-out configurations that only x2iedn instances meet.
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
✓
x2iedn instances with high network bandwidth.
The x2iedn instances are specifically designed for SAP HANA scale-out configurations, offering high memory per vCPU and dedicated high network bandwidth via the Elastic Network Adapter (ENA). In a scale-out HANA setup, nodes communicate intensively over the network for data synchronization and shared storage access, so high network throughput directly mitigates the performance degradation during peak hours.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
x2iedn instances with high network bandwidth.
Why this is correct
x2iedn is specifically designed for SAP HANA with high network performance.
- ✗
c5 instances with placement groups.
Why it's wrong here
c5 is compute optimized, not suitable for HANA.
- ✗
r5 instances with enhanced networking.
Why it's wrong here
r5 instances have lower network bandwidth than x2iedn.
- ✗
m5 instances with EBS optimization.
Why it's wrong here
m5 is general purpose, not optimized for HANA.
