Factors to Consider When Selecting an EC2 Instance for SAP HANA
This PAS-C01 practice question tests your understanding of technology. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which THREE factors should be considered when selecting an EC2 instance type for an SAP HANA production system? (Choose three.)
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
✓
The instance type must have sufficient memory capacity for the HANA database.
Option A is correct because SAP HANA is an in-memory database that loads all data into RAM for processing, so the EC2 instance must have sufficient memory capacity to accommodate the HANA database size, including overhead for operations and growth. AWS provides specific EC2 instance types (e.g., x1e, x1, r5, u-6tb1) with large memory configurations tailored for SAP HANA workloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume GPU acceleration (option C) is needed for HANA analytics due to the term 'analytics,' but SAP HANA does not leverage GPUs; instead, it uses CPU SIMD instructions and memory bandwidth for high-performance query processing.
Detailed technical explanation
How to think about this question
SAP HANA relies on a columnar in-memory database engine where data is compressed and stored in main memory, so memory sizing must account for the data footprint, row store, and additional buffers (e.g., 20-30% overhead). AWS SAP HANA certified instances follow the SAP HANA Tailored Data Center Integration (TDI) model, and network bandwidth (option B) is critical for HANA system replication (HSR) using TCP/IP and for backups to Amazon S3 or EBS, where insufficient bandwidth can cause replication lag or backup failures.
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.
TExam Day Tips
- 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
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.

Same concept, more angles
2 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. Which TWO of the following are valid considerations when sizing an SAP HANA instance on AWS for a production environment? (Choose 2.)
hard- A.Use EBS consistency groups for snapshot backups
- ✓ B.Consider instance store volumes for temporary data and high I/O throughput
- ✓ C.Ensure the instance type supports EBS optimization for dedicated network bandwidth
- D.Select an instance with at least 64 GB memory per HANA node
- E.Use a single large EBS volume to simplify management
Why B: Instance store volumes provide very high I/O throughput and low latency, which is critical for SAP HANA's temporary data (e.g., /hana/tmp, /hana/log) and for redo log writes. They are ephemeral but offer the performance needed for production workloads, making this a valid sizing consideration.
Variation 2. Which THREE factors should be considered when selecting an EC2 instance type for an SAP HANA production system?
medium- ✓ A.Memory (RAM) size
- ✓ B.SAP certification
- ✓ C.Network bandwidth
- D.Instance store volumes
- E.GPU capabilities
Why A: The correct answers are A, B, and C. SAP HANA is an in-memory database, so memory size (RAM) is critical. The instance must be SAP-certified to ensure compatibility and performance. Network bandwidth is important for HANA system replication and data transfer. Option D is incorrect because HANA uses EBS volumes for persistent storage, not instance store (which is ephemeral). Option E is incorrect because GPUs are not required for SAP HANA.
