PAS-C01 Migration Practice Question
A company is migrating their SAP S/4HANA system to AWS. They plan to use SAP HANA Cockpit for migration. During the pre-migration assessment, they find that the on-premises HANA system uses a mix of row and column store tables. The target AWS HANA instance is provisioned on a memory-optimized instance. They want to ensure optimal performance post-migration. Which additional step should they take?
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
✓
Convert row store tables to column store tables where possible
Converting row store tables to column store improves performance for analytical workloads, which is typical for S/4HANA. Option A is wrong because reducing memory allocation could degrade performance. Option B is wrong because disabling compression would increase storage and memory usage. Option D is wrong because increasing parallelism may not help if the storage layout is suboptimal.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduce the memory allocation of the HANA instance
Why it's wrong here
Reducing memory allocation could degrade performance.
- ✗
Disable data compression on the target HANA instance
Why it's wrong here
Disabling compression would increase storage and memory usage.
- ✓
Convert row store tables to column store tables where possible
Why this is correct
Converting row store tables to column store where possible improves performance for analytical workloads, which is typical for S/4HANA. This is the correct additional step.
- ✗
Increase the number of HANA index servers
Why it's wrong here
Increasing the number of HANA index servers may not help if the storage layout is suboptimal. The key issue is the table storage type.
