PAS-C01 Migration Practice Question
A company is migrating an SAP HANA database to AWS. The source system uses a Linux filesystem with a specific block size. After migration, the performance is lower than expected. What is the most likely cause?
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 Amazon EBS volume block size does not match the SAP HANA requirements
SAP HANA on AWS requires the EBS volume to have a block size that matches SAP HANA's requirements (typically 4 KiB). If the source system used a different block size (e.g., 512 bytes), performance degradation can occur. Option A (placement group) affects network latency, not block size performance. Option B (IOPS) is provisioned, but even with sufficient IOPS, block size mismatch can cause poor performance. Option D (encryption) does not impact block size or performance significantly.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The EC2 instance is not in a placement group
Why it's wrong here
Placement groups affect network performance, not block size.
- ✗
The Amazon EBS volume is not provisioned with enough IOPS
Why it's wrong here
IOPS provisioning is separate from block size.
- ✓
The Amazon EBS volume block size does not match the SAP HANA requirements
Why this is correct
SAP HANA requires 4 KiB block size on AWS, mismatch reduces performance.
- ✗
The EBS volume encryption is enabled, causing overhead
Why it's wrong here
Encryption overhead is minimal.
