PAS-C01 Design of SAP Workloads on AWS Practice Question
A company plans to migrate its SAP ERP system to AWS. The system currently runs on IBM Db2 and uses a large amount of memory. The architect needs to choose an EC2 instance type that is SAP certified and provides high memory. Which instance family should the architect select?
⚠ Common exam trap
A common mix-up: candidates confuse memory-optimized families (like R5) with SAP-certified high-memory families (like X1e), not realizing that SAP certification requires specific instance types that have passed SAP's validation for large memory configurations and database compatibility.

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.32xlarge
The x1e.32xlarge instance is SAP-certified for high-memory workloads and is specifically designed for large in-memory databases like IBM Db2. It offers up to 3,904 GiB of memory, making it suitable for SAP ERP systems that require a large memory footprint. Other instance families like C5, R5, and I3 are not SAP-certified for high-memory SAP workloads or lack the necessary memory capacity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
c5.18xlarge
Why it's wrong here
c5 instances are compute-optimized and not ideal for high-memory SAP workloads.
- ✓
x1e.32xlarge
Why this is correct
x1e instances are SAP-certified with up to 3,904 GiB of memory, suitable for large SAP systems.
- ✗
r5.24xlarge
Why it's wrong here
r5 instances are memory-optimized but x1e provides higher memory sizes certified for SAP.
- ✗
i3.16xlarge
Why it's wrong here
i3 instances are storage-optimized with NVMe SSD, not designed for high-memory workloads.
