What type of Tanium question might you use to find the operating system on multiple endpoints?

The correct choice pertains to a counting question, which is specifically designed to aggregate information from multiple endpoints efficiently. When seeking to identify the operating system across various machines within a network, a counting question allows you to compile data on features or attributes present on these endpoints, returning a tally of the operating systems detected.

This functionality is vital in environments where understanding the OS landscape can impact decisions on software deployment, security measures, and overall network management. Counting questions are powerful as they summarize the data into a singular output which reflects the prevalence of each operating system, providing insights more effectively than other types of questions.

In contrast, action questions are geared towards initiating specific tasks or commands on endpoints, while non-counting questions may retrieve data but do not aggregate or summarize it in a way that's conducive to quantitative analysis. Variable questions involve parameters that may change based on user input, focusing less on counting and more on retrieving specific data points. Thus, the characteristics of the counting question align perfectly with the goal of identifying multiple operating systems across endpoints in a concise manner.
