A technician is manually updating Windows workstations.

Creating a domain and joining the workstations to it provides centralized management and control over the computers, making the environment much more manageable.

Here's why a domain is beneficial:

Centralized administration: Manage user accounts, security policies, software installations, and updates from a single location (the domain controller).

Group Policy: Implement and enforce security policies, configure system settings, and control user access to resources.

Simplified updates: Deploy software updates and patches to multiple computers simultaneously.

Improved security: Enforce stronger password policies, control access to sensitive data, and enhance overall network security.

Here's why the other options are less suitable:

A. Downgrade all workstations from the Pro version to the Home version of the OS: The Home version has fewer features and management capabilities than the Pro version, making it less suitable for a business environment.

B. Upgrade all workstations from the Pro version to Pro for Workstations: While Pro for Workstations has advanced features, it's designed for high-performance tasks and might not be necessary for all users.

D. Make sure all workstations are operating under the same workgroup name: While being in the same workgroup allows for basic network sharing, it doesn't provide the centralized management capabilities of a domain.
