PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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.
A company is designing an SAP HANA multi-node scale-out system on AWS. Which two of the following are required for the network configuration? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a separate subnet for HANA internal communication.
Option D is correct because SAP HANA multi-node scale-out systems require a dedicated subnet for internal inter-node communication to ensure low latency and high throughput. This separate network isolates HANA internal traffic (e.g., internal SQL and replication traffic) from other network traffic, which is critical for performance and stability.
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.
✗
Assign public IP addresses to each node for inter-node communication.
Why it's wrong here
Public IPs are not required and may introduce latency.
✗
Configure an Elastic Load Balancer to distribute traffic among nodes.
Why it's wrong here
HANA scale-out uses direct connections.
✗
Enable EBS optimization on all EC2 instances.
Why it's wrong here
Not a network requirement for scale-out.
✓
Create a separate subnet for HANA internal communication.
Why this is correct
Isolates HANA node-to-node traffic.
Related concept
Read the scenario before looking for a memorised answer.
✓
Place all nodes in a cluster placement group.
Why this is correct
Ensures low latency between nodes.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse external-facing components (like Elastic Load Balancers or public IPs) with internal cluster communication requirements, or they mistakenly think EBS optimization is a network prerequisite for HANA scale-out, when in fact the focus should be on placement groups and dedicated subnets for low-latency inter-node traffic.
Detailed technical explanation
How to think about this question
SAP HANA scale-out nodes use internal network interfaces for data replication and workload distribution, typically over TCP/IP with high bandwidth and low latency. A cluster placement group (Option E) ensures all nodes are in close physical proximity within a single Availability Zone, minimizing network latency and maximizing throughput for HANA's internal communication. The separate subnet (Option D) allows for dedicated routing and security group rules, preventing interference from other workloads and ensuring consistent network performance.
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
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.
