DBS-C01 Deployment and Migration Practice Question
A company is migrating a MySQL database from on-premises to Amazon RDS for MySQL. They want to use native MySQL replication to minimize downtime. Which configuration is required in the on-premises MySQL server?
⚠ Common exam trap
Watch out — candidates often confuse logging features (slow query log, audit log, error log) with the binary log, which is the only log that provides the change data stream required for native MySQL replication.

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
✓
Enable binary logging with binlog_format = ROW
Native MySQL replication requires binary logging on the source server to capture all changes. Setting binlog_format = ROW ensures that row-level changes are logged, which is the recommended format for cross-version replication and is required by Amazon RDS for MySQL to support replication from an external source. Without binary logging enabled, the on-premises MySQL server cannot act as a replication master.
