Which of the following is NOT a core asset listed in IT Glue?

In the context of IT Glue, core assets are fundamental components to managing documentation and information effectively. Software licenses, while important, do not fall under the category of core assets in IT Glue. Core assets typically include elements that are essential for day-to-day IT operations, such as configurations, passwords, and SSL trackers.

Configurations are critical as they help document how systems are set up and maintained. Passwords are vital for security and access control, and SSL trackers are necessary for managing security certificates effectively. These components are typically the foundational building blocks that support an IT organization's documentation practices.

Software licenses, while necessary for compliance and asset management, serve a more specific purpose and are often managed separately in asset management platforms or tools. Thus, they do not fit the core asset classification in IT Glue.
