DBS-C01 Deployment and Migration Practice Question
A company is migrating an on-premises MySQL database to Amazon RDS for MySQL. The company wants to minimize application changes. Which endpoint type should the application use after migration?
⚠ Common exam trap
Many candidates confuse RDS instance endpoints with Aurora cluster endpoints, mistakenly selecting the cluster endpoint (Option B) for a standard RDS MySQL migration, even though cluster endpoints are exclusive to Aurora and not applicable to single-instance RDS deployments.

Correct answer & explanation
✓
RDS instance endpoint (DNS name)
The RDS instance endpoint (DNS name) is the standard connection endpoint for a single RDS DB instance, which is the target of a direct migration from on-premises MySQL to Amazon RDS for MySQL. This endpoint requires no application changes, as the application simply replaces the old on-premises hostname with the RDS instance DNS name, maintaining the same MySQL protocol and connection logic.
