What are the two default groups to which a new user is automatically added?

A new user is automatically added to the "Everyone" group by default because this group serves as a foundational category within user management systems, granting broad access rights and permissions necessary for basic functionality. It ensures that all users have some level of access to resources and services essential for their operation.

The "Everyone" group typically includes all authenticated users, making it a default inclusion when a new user is created. This allows seamless interaction with applications and resources without the need for immediate administrative actions to grant access.

In contrast, groups like "Trusted Users" or "Network Administrators" usually require specific privileges or roles that might not be available to all new users. "Guest Users" typically have restricted access, often used for external users or those with limited permissions, which is not suitable for new users who need basic functionalities immediately. Therefore, the "Everyone" group stands out as the correct answer for any new user’s automatic inclusion.
