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
✓
AWS Database Migration Service (AWS DMS) with ongoing replication
AWS DMS with ongoing replication (change data capture) is the correct choice because it can continuously capture changes from the RDS for SQL Server source and replicate them to an Amazon S3 bucket in near real time. Option A (AWS Glue) is incorrect because AWS Glue is a batch ETL service, not designed for real-time change data capture. Option C (Amazon RDS for SQL Server native replication) is incorrect because native replication features like Always On Availability Groups or log shipping replicate data to another SQL Server instance, not directly to S3. Option D (Amazon Kinesis Data Streams) is incorrect because while it can ingest streaming data, it would require additional custom application logic to capture changes from RDS and push to Kinesis, making it less straightforward than DMS for this use case.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Glue
Why it's wrong here
Glue is for batch ETL, not real-time change data capture.
- ✓
AWS Database Migration Service (AWS DMS) with ongoing replication
Why this is correct
DMS supports change data capture to replicate changes to S3 nearly in real time.
- ✗
Amazon RDS for SQL Server native replication
Why it's wrong here
Native replication does not directly write to S3.
- ✗
Amazon Kinesis Data Streams
Why it's wrong here
Kinesis can ingest data but requires additional setup to capture database changes.
