When preparing for testing in Manufacturing Cloud, what must test users have for mobile access?

To enable mobile access for test users in the Manufacturing Cloud, it is essential that they are assigned the Mobile User permission. This permission grants users the necessary access rights to utilize the mobile capabilities of the Salesforce platform effectively. Without this permission, users would likely face limitations or be completely restricted from accessing mobile features, which would hinder their ability to perform testing in a mobile environment.

The other options do not address the essential requirement for mobile access. While some features might have limitations on mobile or require specific setups, the core requirement remains that Mobile User permission is crucial for enabling comprehensive mobile functionality for test users. Thus, assigning this permission is vital to ensure that users can test and access the necessary features on their mobile devices.
