Exam question from Amazon's AWS-SysOps
Question #: 537
Topic #: 1
[All AWS-SysOps Questions]

An AWS CloudFormation template creates an Amazon RDS instance. This template is used to build up development environments as needed and then delete the stack when the environment is no longer required. The RDS-persisted data must be retained for further use, even after the CloudFormation stack is deleted.
How can this be achieved in a reliable and efficient way?

  • A. Write a script to continue backing up the RDS instance every five minutes
  • B. Create an AWS Lambda function to take a snapshot of the RDS instance, and manually execute the function before deleting the stack
  • C. Use the Snapshot Deletion Policy in the CloudFormation template definition of the RDS instance
  • D. Create a new CloudFormation template to perform backups of the RDS instance, and run this template before deleting the stack

Selected Answer: C
Using a Snapshot Deletion Policy is a reliable and efficient way to retain the data because it automates the process within the CloudFormation stack itself. It ensures that the final snapshot is created and preserved, eliminating the need for manual intervention or separate scripts.

C : With the DeletionPolicy attribute you can preserve or (in some cases) backup a resource when its stack is deleted. You specify a DeletionPolicy attribute for each resource that you want to control. If a resource has no DeletionPolicy attribute, AWS CloudFormation deletes the resource by default.
