Which file is necessary for including environment-specific properties in your deployment?

The correct choice emphasizes the importance of a Customization File when it comes to including environment-specific properties in your deployment. A Customization File is designed to hold overrides and settings that can change depending on the environment where the application is running, such as development, testing, or production.

This file allows developers to specify different configurations for various environments without changing the core application code. This capability is particularly important in maintaining consistency and ensuring that sensitive or environment-specific details—like database connections or API keys—are managed appropriately across deployment stages.

In contrast, while other files like Configuration and Settings Files could potentially hold various settings, they do not specifically focus on the customization aspect for different environments in the same way. A Deployment File generally refers to something that outlines the components and assets being deployed, rather than managing environmental properties. This underscores the importance of utilizing the correct file type to ensure seamless deployment processes tailored to each environment.
