Which types of deployments can reference environment variables?

The choice indicating that all types of deployments can reference environment variables is correct because environment variables serve as a flexible configuration mechanism that can be utilized across various deployment types.

In the context of deployment processes, environment variables allow users to manage configurations and settings dynamically without hardcoding values. This is crucial in scenarios where different environments such as development, testing, and production might require different configurations. For example:

• In the case of Git commits, environment variables can help set parameters that might affect how the code is built or tested.

• Data deployments can leverage environment variables to drive changes in data configurations or settings that need to be updated depending on the target environment.

• Custom settings deployments can utilize environment variables for settings that might need to adjust based on the environment the deployment is taking place in.

Thus, the ability to reference environment variables enhances the versatility and adaptability of all types of deployments, making it easier to manage changes across different systems and stages in the deployment pipeline.
