The correct answer is to redistribute the tables across nodes using HANA’s table partitioning features. In a scale-out architecture, SAP HANA relies on hash-based or round-robin partitioning to distribute data evenly across worker nodes; when this distribution becomes skewed, query performance degrades because some nodes handle disproportionate workloads. The targeted fix is to use ALTER TABLE ... REORGANIZE or reload the data, which forces HANA to re-partition and rebalance the rows across all nodes. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that adding nodes or scaling instance types does not correct existing data skew—only a redistribution operation addresses the root cause. A common trap is to confuse hardware scaling with data-level tuning, so remember the memory tip: “Reorganize, not resize” to fix uneven distribution.
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. 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 running SAP HANA on AWS using a scale-out architecture with multiple worker nodes. The system is used for real-time analytics. Recently, query performance has degraded. The HANA administrator notices that the data is not evenly distributed across nodes. What is the best course of action?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Redistribute the tables across nodes using HANA's table partitioning features.
HANA scale-out relies on table partitioning and distribution to ensure even data distribution. Redistributing tables using ALTER TABLE with REORGANIZE or reloading data can fix imbalance. Option A (add nodes) may help but does not fix existing imbalance. Option B (change instance type) is not directly related. Option D (memory) is not the issue. Option C is the targeted fix.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Redistribute the tables across nodes using HANA's table partitioning features.
Why this is correct
Partitioning and redistribution ensures even data distribution.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the memory allocation for the HANA database.
Why it's wrong here
Memory allocation does not affect data distribution.
✗
Add more worker nodes to the scale-out cluster to distribute the load.
Why it's wrong here
Adding nodes does not automatically rebalance existing data.
✗
Upgrade the EC2 instance type of all nodes to a memory-optimized type.
Why it's wrong here
Memory increase does not solve distribution problem.

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.
