PAS-C01 Migration Practice Question
A company is migrating a critical SAP HANA database from on-premises to AWS. The database is 6 TB, and the migration must be completed within a 4-hour downtime window. The network bandwidth between on-premises and AWS is 1 Gbps. Which approach should the company take to meet the downtime requirement?
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 physically transfer the data, then use AWS DMS for ongoing replication.
AWS Snowball Edge enables physical transfer of the 6 TB data, which is feasible within the 4-hour window despite the 1 Gbps network constraint. After the initial load, AWS DMS can be used for ongoing CDC replication. Option A is wrong because converting schema with SCT and restoring after upload still requires the initial upload over the network, which would exceed the downtime window. Option B is wrong because AWS DMS with CDC over the existing network for the full load cannot transfer 6 TB in 4 hours at 1 Gbps. Option D is wrong because a direct online migration over the network cannot meet the downtime requirement due to bandwidth limitations.
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 SCT to convert the schema, then export to Amazon S3 and restore into HANA on EC2.
Why it's wrong here
Uploading to S3 over 1 Gbps would still take too long.
- ✗
Use AWS DMS with change data capture (CDC) and start with a full load over the network.
Why it's wrong here
Full load over the network would exceed the downtime window.
- ✓
Use AWS Snowball Edge to physically transfer the data, then use AWS DMS for ongoing replication.
Why this is correct
Snowball Edge can transfer large data offline, meeting the time constraint.
- ✗
Perform a direct online migration using AWS DMS over the existing network.
Why it's wrong here
At 1 Gbps, transferring 6 TB would take over 13 hours, exceeding the 4-hour window.
