Which of the following MUST be done when imaging a Windows Server that will be used as a template?

Removing software is an optional customization based on template requirements, not a mandatory step for all imaging templates.

Running Windows Updates is good practice to keep the template current, but it is not a mandatory step that prevents system conflicts when deploying multiple instances like Sysprep.

Updating drivers is beneficial but not universally mandatory for a template; Sysprep handles driver generalization, and specific driver updates can be managed post-deployment or through other methods.

Sysprep (System Preparation Tool) is essential for imaging a Windows Server as a template because it generalizes the Windows installation by removing system-specific data like security identifiers (SIDs), allowing the image to be deployed to multiple new machines without conflicts.
