SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a large-scale e-commerce platform from on-premises to AWS. The migration plan includes rehosting the application servers and replatforming the database to Amazon Aurora. The company needs to ensure minimal downtime during the cutover. Which strategy should the company use for the database migration?
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 DMS with a full load and ongoing replication to keep the target synchronized
AWS Database Migration Service (DMS) with ongoing replication allows continuous data sync, enabling a cutover with minimal downtime. Using a snapshot backup requires downtime for restoration. AWS DMS with full load only does not keep the target up-to-date. Using an application-level dual-write is complex and error-prone.
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 DMS with a full load and ongoing replication to keep the target synchronized
Why this is correct
Correct. Ongoing replication reduces downtime during cutover.
- ✗
Use AWS DMS with a full load only, then cut over
Why it's wrong here
Without ongoing replication, changes after the full load are lost, causing data loss.
- ✗
Use an application-level dual-write to both databases during the cutover
Why it's wrong here
Dual-write is complex and can lead to data inconsistency.
- ✗
Take a snapshot of the on-premises database and restore it to Amazon Aurora
Why it's wrong here
Restoring from a snapshot requires downtime for the final sync.
