PAS-C01 Migration Practice Question
A company is migrating a 10 TB SAP HANA database to AWS. They have a limited time window and need to minimize migration time. The database is running on a physical server with 1 Gbps network link to AWS. Which migration strategy 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 database files offline
AWS Snowball Edge provides a high-capacity physical device for offline data transfer, avoiding network bandwidth limitations. Option A is wrong because AWS Direct Connect requires setup time and still is limited by 1 Gbps bandwidth, which would still result in long transfer times for 10 TB. Option C is wrong because AWS SCT is for schema conversion, not data transfer. Option D is wrong because AWS DMS over a 1 Gbps link would take too long for 10 TB of data.
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 Direct Connect to increase bandwidth before migration
Why it's wrong here
Setting up AWS Direct Connect takes time and even with increased bandwidth, transferring 10 TB over a network connection would still be slower than using an offline physical device like AWS Snowball Edge, especially given the limited time window.
- ✓
Use AWS Snowball Edge to transfer the database files offline
Why this is correct
Snowball Edge can transfer 10 TB quickly via physical shipment.
- ✗
Use AWS SCT to convert the database and then use DMS
Why it's wrong here
SCT does not handle large data transfer.
- ✗
Use AWS DMS over the existing network link
Why it's wrong here
Using AWS DMS over the existing 1 Gbps network link would take too long for a 10 TB database. The transfer time would be many hours or even days, exceeding the limited time window. Snowball Edge provides a faster offline transfer.
