PAS-C01 Migration Practice Question
A company is migrating their SAP Business Suite on SAP HANA to AWS. They need to transfer the data securely and efficiently. The source environment is in a different country with limited network bandwidth. The total data size is 100 TB. What is the most efficient migration approach?
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 for the initial data load, then AWS DMS for ongoing replication
For a 100 TB migration with limited network bandwidth, an offline transfer using AWS Snowball Edge is most efficient for the initial data load. After loading the data into AWS, AWS DMS can handle ongoing replication for any changes. This approach avoids the time and bandwidth constraints of network-based transfers. Option A (Direct Connect + DMS) would still require significant network time for the full load. Option C (VPN + DMS) is also network-bound and slow. Option D (DataSync over internet) is not efficient for 100 TB.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Establish an AWS Direct Connect connection and use AWS DMS for full load and replication
Why it's wrong here
AWS Direct Connect provides a dedicated network connection, but with limited bandwidth and 100 TB, the initial transfer would take too long. It is not the most efficient.
- ✓
Use AWS Snowball Edge for the initial data load, then AWS DMS for ongoing replication
Why this is correct
AWS Snowball Edge allows offline transfer of large data volumes, bypassing bandwidth constraints. After the initial load, AWS DMS can handle ongoing replication. This is the most efficient approach.
- ✗
Use a VPN connection and AWS DMS for both full load and continuous replication
Why it's wrong here
Using VPN and DMS relies on network transfer for the full load, which is slow over limited bandwidth and not efficient for 100 TB.
- ✗
Use AWS DataSync over the internet to transfer data and then switch to DMS
Why it's wrong here
AWS DataSync is optimized for online data transfer over network, but for 100 TB with limited bandwidth, it would be very slow and not efficient.
