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 full load and ongoing replication using CDC
AWS DMS with full load and ongoing replication using CDC allows continuous syncing after the full load, minimizing downtime. Option D (full load only) would cause downtime during migration. Option B (AWS DataSync) is for file-based data, not databases. Option C (AWS SCT) is for schema conversion only, not data migration.
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 full load and ongoing replication using CDC
Why this is correct
Ongoing replication with CDC keeps the target in sync until cutover, minimizing downtime.
- ✗
Use AWS DataSync for the database files
Why it's wrong here
DataSync is for file transfers, not live database migration.
- ✗
Use AWS SCT to convert schema and then copy data manually
Why it's wrong here
SCT converts schema but does not perform ongoing replication.
- ✗
Use AWS DMS with full load only
Why it's wrong here
Full load only requires application downtime during the entire migration.
