PAS-C01 Technology Practice Question
A company wants to migrate its SAP ERP system from on-premises to AWS using the SAP Application Performance Standard (SAPS) sizing approach. The current on-premises system has a SAPS rating of 15,000. The company needs to select an EC2 instance type that can provide sufficient compute capacity. Which EC2 instance family is most suitable for SAP HANA workloads?
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
✓
x1e
(x1e) is correct because SAP HANA is an in-memory database that requires high memory capacity, and the x1e instance family is memory-optimized and certified for SAP HANA workloads. Option A (c5) is wrong because it is compute-optimized and does not offer the memory required for HANA. Option B (p3) is wrong because it is GPU-optimized for machine learning, not memory-intensive databases. Option D (m5) is wrong because it is general-purpose and may not provide the dedicated memory or certification for HANA.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
c5
Why it's wrong here
c5 is compute-optimized, not suitable for HANA.
- ✗
p3
Why it's wrong here
p3 is GPU instances, not for HANA.
- ✓
x1e
Why this is correct
The x1e instance family is designed for high-memory SAP HANA workloads, offering up to 3,904 GiB of RAM per instance, which directly satisfies the SAPS rating of 15,000 by providing the memory-to-CPU ratio required for in-memory database processing. This constraint—memory capacity for SAPS—differentiates x1e from general-purpose families that lack sufficient RAM for HANA’s columnar storage.
- ✗
m5
Why it's wrong here
m5 is general purpose, not ideal for HANA.
