PAS-C01 Migration Practice Question
A company wants to migrate a 10 TB SAP HANA database to AWS with minimal downtime. The network bandwidth between the on-premises data center and AWS is 1 Gbps. Which migration method is most suitable?
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
✓
Use AWS Snowball Edge to transfer the initial data load, then use AWS DMS for ongoing replication.
Given the large data size and limited bandwidth, using AWS Snowball Edge for initial load reduces network dependency. AWS DMS with CDC requires a stable connection but initial load over 1 Gbps would take >22 hours. Backup/restore over network also suffers from bandwidth. SAP HANA System Replication requires high bandwidth and low latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use AWS Snowball Edge to transfer the initial data load, then use AWS DMS for ongoing replication.
Why this is correct
Snowball Edge handles large data offline; DMS can do CDC after initial load.
- ✗
Use SAP HANA System Replication directly over the internet.
Why it's wrong here
Requires high bandwidth and low latency; 1 Gbps may not be sufficient.
- ✗
Use AWS DMS with ongoing replication to migrate data incrementally.
Why it's wrong here
Initial load over 1 Gbps would take too long for a 10 TB database.
- ✗
Use AWS Backup to back up the database to S3 and restore to an EC2 instance.
Why it's wrong here
Backup over network still limited by bandwidth; downtime may be high.
