DBS-C01 Deployment and Migration Practice Question
A company is migrating a PostgreSQL database to Amazon Aurora PostgreSQL. They want to use the AWS DMS for the migration. Which THREE resources need to be created in the AWS account?
⚠ Common exam trap
The trap here is that candidates might think CloudFormation is mandatory for provisioning DMS resources, but the exam tests that only the replication instance and both endpoints are the core required components for a DMS migration task.
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
✓
DMS target endpoint pointing to Aurora PostgreSQL.
AWS DMS requires a target endpoint that specifies the connection details for the Amazon Aurora PostgreSQL database. This endpoint tells DMS where to load the migrated data, and it must be configured with the correct database name, credentials, and VPC settings to ensure successful connectivity during the migration task.
