- A
Add an additional HANA node to create a scale-out configuration and distribute the load.
Scale-out can be added online if using HANA system replication, but involves new instances. However, among options, this is the only one that adds CPU without stopping existing instance (though new instances needed).
- B
Enable Multi-AZ deployment for high availability.
Why wrong: Multi-AZ does not add CPU capacity.
- C
Change the EC2 instance type to a larger size using the AWS Management Console.
Why wrong: Changing instance type requires stopping the instance, causing downtime.
- D
Increase the provisioned IOPS on the EBS volumes.
Why wrong: IOPS increase does not add CPU.

PAS-C01 Technology Practice Question
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.
A company runs SAP HANA on AWS using a scale-up configuration. The system is experiencing high CPU utilization on the HANA server during peak load. The SAP administrator wants to add more CPU resources without disruption. Which action should be taken?
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
✓
Add an additional HANA node to create a scale-out configuration and distribute the load.
Option A is correct because adding an additional HANA node to create a scale-out configuration allows the system to distribute the workload across multiple nodes, providing additional CPU resources without downtime. SAP HANA supports scale-out configurations where new nodes can be added online using the 'ALTER SYSTEM ADD WORKER' command, enabling CPU scaling without restarting the existing system.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Enable Multi-AZ deployment for high availability.
Why it's wrong here
Multi-AZ does not add CPU capacity.
- ✗
Change the EC2 instance type to a larger size using the AWS Management Console.

Changing instance type requires stopping the instance, causing downtime.
- ✗
Increase the provisioned IOPS on the EBS volumes.
Why it's wrong here
IOPS increase does not add CPU.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse scaling up (changing instance type) with scaling out (adding nodes), and assume that changing the instance type can be done without disruption, but AWS requires stopping the instance for a type change, which causes downtime.
Detailed technical explanation
How to think about this question
SAP HANA scale-out configurations use a shared-nothing architecture where each node has its own CPU, memory, and storage, and data is partitioned across nodes. The 'ALTER SYSTEM ADD WORKER' command dynamically adds a new node to the cluster, and HANA automatically redistributes data partitions (e.g., using hash or round-robin partitioning) to balance the load. In real-world scenarios, this is critical for handling unpredictable spikes in OLAP workloads without requiring a maintenance window.
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.
