SAP HANA EC2 Instance Type Selection: Which Instance to Choose?

This PAS-C01 practice question tests your understanding of migration. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

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

Option A (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.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.

    Related concept

    Read the scenario before looking for a memorised answer.

  • 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.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.

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.
