Which feature helps in the rapid troubleshooting of endpoint issues within Tanium?

The selection of Live Query as the correct feature for rapid troubleshooting of endpoint issues within Tanium highlights its real-time capabilities. Live Query allows users to ask questions about the current state of endpoints and receive immediate responses. This feature is particularly useful for troubleshooting because it enables administrators to gather specific and up-to-date information from endpoints swiftly, ensuring that they can identify and diagnose issues as they arise.

With Live Query, users can probe different aspects of an endpoint, such as the status of services, current processes, or any unusual behavior, without waiting for scheduled reports or system updates. This instant access to data is invaluable in a troubleshooting context, where timely information can lead to quicker resolutions and minimize downtime.

In contrast, the other features, while beneficial in their own contexts, do not provide the same immediacy. Alert Notifications might inform users of issues but do not assist in diagnosing the underlying causes. Data Visualization can help in understanding trends and patterns over time but is not targeted for live issue resolution. Periodic Reporting provides regular updates and insights but lacks the promptness that Live Query offers when immediate data retrieval is necessary for troubleshooting.
