Which tool is used for real-time interaction with endpoints in Tanium?

The correct choice is Tanium Ask, as it is designed specifically for real-time interaction with endpoints. Tanium Ask enables users to query endpoints in real time for immediate data retrieval and response. This capability is essential for tasks that require instant insights into endpoint status, such as checking configurations, running processes, or gathering system information quickly. The tool operates interactively, allowing users to pose questions and receive answers directly from the endpoints, thereby facilitating swift decision-making and troubleshooting.

In contrast, the Tanium Client operates on the endpoint itself, gathering and sending data to the Tanium Server but does not directly provide the interactive querying interface. Tanium Action is focused on executing commands or scripts on endpoints rather than real-time querying, while Tanium Trends is used for analyzing and visualizing data over time instead of engaging in immediate interaction.
