Which of the below mentioned steps are not required while using Cloudformation?
A . Create a stack
B . Configure a service
C . Create and upload the template
D . Provide the parameters configured as part of the template

Answer: B

Explanation:

AWS Cloudformation is an application management tool which provides application modelling, deployment, configuration, management and related activities. AWS CloudFormation introduces two concepts: the template and the stack. The template is a JSON-format, text-based file that describes all the AWS resources required to deploy and run an application. The stack is a collection of AWS resources which are created and managed as a single unit when AWS CloudFormation instantiates a template. While creating a stack, the user uploads the template and provides the data for the parameters if required.
