Domain 3.1: Operational Excellence — AWS SAP-C02 Practice Question 73

How to approach this question

Identify the CloudFormation feature that protects individual resources from deletion during updates.

Full Answer

A.Add a DeletionPolicy attribute with the value 'Retain' to the RDS database resource in the CloudFormation template.✓ Correct

In AWS CloudFormation, certain updates to a resource (like changing the DB identifier) require the resource to be replaced. CloudFormation does this by creating a new resource and deleting the old one. To prevent accidental data loss, you should add the `DeletionPolicy: Retain` attribute to stateful resources like databases. If CloudFormation attempts to replace the resource, it will create the new one but leave the old one intact.
