PAS-C01 Migration Practice Question
A company is migrating an SAP HANA system from on-premises to AWS. The HANA system uses a large amount of memory (2 TB). Which EC2 instance type is most suitable for this workload?
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.32xlarge
(x2iedn.32xlarge) is correct because it is a memory-optimized instance with up to 4 TB of memory, making it suitable for SAP HANA workloads requiring 2 TB of memory. Option B (c5n.18xlarge) is wrong because c5n instances are compute-optimized and have less memory. Option C (m5n.24xlarge) is wrong because m5n instances are general-purpose and cannot support 2 TB of memory. Option D (r5.24xlarge) is wrong because r5 instances have a maximum memory of 768 GB.
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.32xlarge
Why this is correct
The x2iedn.32xlarge instance is memory-optimized and can support up to 4 TB of memory, making it ideal for large SAP HANA deployments.
- ✗
c5n.18xlarge
Why it's wrong here
The c5n.18xlarge is a compute-optimized instance with limited memory, not suitable for memory-intensive SAP HANA workloads.
- ✗
m5n.24xlarge
Why it's wrong here
The m5n.24xlarge is a general-purpose instance with insufficient memory for a 2 TB SAP HANA system.
- ✗
r5.24xlarge
Why it's wrong here
The r5.24xlarge instance has a maximum memory of 768 GB, which is below the required 2 TB for the SAP HANA workload.

Same concept, more angles
3 more ways this is tested on PAS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is migrating an SAP system from on-premises to AWS. The migration involves rehosting SAP HANA on EC2. Which of the following is the best practice for sizing the EC2 instance?
hard- A.Use a memory-optimized EC2 instance with the required memory.
- ✓ B.Use an EC2 instance that is listed in the SAP Certified and Supported SAP HANA Hardware Directory.
- C.Use a general-purpose EC2 instance with sufficient vCPUs and memory.
- D.Use a compute-optimized EC2 instance to ensure high CPU performance.
Why B: SAP HANA instances must be SAP-certified. The AWS instance types that are SAP-certified for HANA (e.g., r5.metal, u-6tb1) should be used. General-purpose instances are not certified. Memory optimized instances are correct but must be specific certified types. Compute optimized are not suitable.
Variation 2. A company is migrating a large-scale SAP HANA workload to AWS. The system requires high memory and low latency. Which EC2 instance type is most suitable for this migration?
medium- ✓ A.x1e.32xlarge
- B.m5.24xlarge
- C.c5.18xlarge
- D.r5.24xlarge
Why A: The x1e.32xlarge is purpose-built for high-memory, SAP HANA workloads, offering up to 3,904 GiB of memory and high-speed NVMe SSD storage with low-latency networking. It is certified by SAP for running production HANA environments, making it the most suitable choice for this migration.
Variation 3. A company is migrating a large SAP HANA workload to AWS. The source system runs on IBM Power Systems. They need to ensure that the target AWS infrastructure meets SAP certification requirements. Which EC2 instance type should they choose?
hard- A.m5.24xlarge
- B.c5.18xlarge
- C.i3en.24xlarge
- ✓ D.x1e.32xlarge
Why D: x1e.32xlarge is certified for SAP HANA production workloads. Therefore, Option D is correct. Option A (m5.24xlarge) is a general-purpose instance and not certified for SAP HANA. Option B (c5.18xlarge) is compute-optimized and not suitable for SAP HANA's memory requirements. Option C (i3en.24xlarge) is storage-optimized and not SAP HANA certified.
