SAP-C02 Q89 · Storage

Question

A company is using AWS CloudFormation to deploy its infrastructure. The company is concerned that, if a production CloudFormation stack is deleted, important data stored in Amazon RDS databases or Amazon EBS volumes might also be deleted. How can the company prevent users from accidentally deleting data in this way?

Accepted Answer

**Option A: Add a DeletionPolicy attribute to RDS and EBS resources in CloudFormation templates.**

The `DeletionPolicy` attribute is a CloudFormation resource-level attribute specifically designed to control what happens to a resource when:
1. The resource is removed from the template
2. The entire stack is deleted

**How it satisfies each requirement:**

- **Prevent data loss on stack deletion**: Setting `DeletionPolicy: Retain` tells CloudFormation to keep the resource (and its data) even if the stack is deleted. The resource becomes an orphaned resource that still exists in the account.
- **Works for RDS**: `DeletionPolicy: Snapshot` can automatically create a final DB snapshot before deletion, preserving data. `Retain` keeps the entire DB instance.
- **Works for EBS**: `DeletionPolicy
