True or False: Best practice dictates always including a default match when using conditional expressions.

Including a default match when using conditional expressions is considered a best practice because it ensures that there is a defined output for all possible input scenarios. By utilizing a default match, you can avoid unexpected behavior in your Puppet manifests, which can lead to issues such as failed catalogs or unhandled cases.

In complex systems where multiple conditions may be evaluated, the absence of a default match can result in ambiguity and make troubleshooting more difficult. Defining a fallback option helps maintain clarity and robustness in the configuration management process.

This approach not only improves the reliability of your code but also enhances its maintainability. By anticipating cases that may not fit into predefined conditions, you can ensure that your manifests behave as expected and adhere to desired states without introducing unintended side effects.
