PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is migrating its SAP HANA database to AWS and needs to choose the most appropriate EC2 instance type. The workload requires high memory bandwidth and is CPU-intensive. Which instance family would best meet these requirements?
⚠ Common exam trap
Test-takers frequently confuse compute-optimized (C5) or storage-optimized (I3) families with SAP HANA requirements, overlooking that SAP HANA's in-memory nature demands memory-optimized instances like X1e with high memory bandwidth and capacity, not just raw CPU or I/O performance.
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 instance family
The X1e instance family is purpose-built for high-memory, CPU-intensive SAP HANA workloads, offering up to 3.9 TB of memory and high memory bandwidth per vCPU. This aligns with SAP HANA's requirement for large in-memory databases and compute-intensive processing, making D the correct choice.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
M5 instance family
Why it's wrong here
M5 is general-purpose and may not provide sufficient memory bandwidth for HANA.
- ✗
I3 instance family
Why it's wrong here
I3 is storage-optimized for high disk I/O, not for memory bandwidth.
- ✗
C5 instance family
Why it's wrong here
C5 is compute-optimized, not designed for high memory bandwidth in SAP HANA.
- ✓
X1e instance family
Why this is correct
X1e instances are memory-optimized with high memory bandwidth, ideal for SAP HANA workloads.
