    Properties:
      DBInstanceClass: db.r5.large

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

✓

Add 'DeletionProtection': true to the Properties.

Adding 'DeletionProtection': true to the Properties of the AWS::RDS::DBInstance resource enables deletion protection for that DB instance. Option B is incorrect because 'DeletionPolicy: Retain' is a CloudFormation resource-level attribute that retains the resource when the stack is deleted, but it does not prevent deletion of the resource outside of CloudFormation. Option C is incorrect because 'PreventRDSDeletion' is not a valid property for RDS. Option D is incorrect because the correct syntax is 'DeletionProtection': true, not 'Enabled'.
