Which CloudFormation stack policy action should the database engineer implement to meet these requirements?
Use a Deny statement for the Update:Modify action on the production database resources.
Use a Deny statement for the Update:* action on the production database resources.
Use a Deny statement for the Update:Delete action on the production database resources.
Use a Deny statement for the Update:Replace action on the production database resources.
Explanations:
TheUpdate:Modifyaction refers to modifying existing resources. Denying this action would prevent modifications but not delete or replace resources, which is not sufficient for preventing all unwanted changes in a production environment.
TheUpdate:*action applies to all update-related actions (Modify, Delete, Replace), making it the most comprehensive option to prevent changes to the production database resources.
TheUpdate:Deleteaction would prevent deletion of resources but would still allow modifications or replacements. This is insufficient for preventing updates that could affect production resources.
TheUpdate:Replaceaction applies to the replacement of resources, but other actions like modification or deletion could still occur. It does not prevent all types of updates to production resources.
I organize that the answer is:
Use a Deny statement for the Update:* action on the production database resources.
