An engineer is building a dashboard to visualize the number of alerts from various sources.

In Cortex XDR, dashboards and widgets supportdrilldownfunctionality, allowing users to click ona widget element (e.g., an alert name in a bar chart) to view detailed data filtered by the selected value. This is achieved usingXQL (XDR Query Language)queries with dynamic variables that reference the clicked element’s value. In the provided XQL query, the engineer wants to filter alerts based on thealert_nameselected in the widget.

The widget likely displays alert names along thex-axis(e.g., in a bar chart where each bar represents an alert name and its count). When a user clicks on an alert name, the drilldown query should filter the dataset to show only alerts matching that selectedalert_name. In XQL, dynamic filtering for drilldowns uses variables like $x_axis.value to capture the value of the clicked element on the x-axis.

Correct Answer Analysis (B):The variable$x_axis.valueis used to reference the value of the x-axis element (in this case, thealert_name) selected by the user. Completing the query with filter alert_name = $x_axis.value ensures that the drilldown filters the alerts dataset to show only those records where thealert_namematches the clicked value.

Why not the other options?

A. $y_axis.value: This variable refers to the value on the y-axis, which typically represents a numerical value (e.g., the count of alerts) in a chart, not the categoricalalert_name.

C. $x_axis.name: This is not a valid XQL variable for drilldowns. XQL uses $x_axis.value to capture the selected value, not $x_axis.name.

D. $y_axis.name: This is also not a valid XQL variable, and the y-axis is not relevant for filtering byalert_name.

Exact Extract or Reference:

TheCortex XDR Documentation Portalin theXQL Reference Guideexplains drilldown configuration: “To filter data based on a clicked widget element, use $x_axis.value to reference the value of the x-axis category selected by the user” (paraphrased from the Dashboards and Widgets section). TheEDU-262: Cortex XDR Investigation and Responsecourse covers dashboard creation and XQL, noting that “drilldown queries use variables like $x_axis.value to dynamically filter based on user selections” (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetlists “dashboards and reporting” as a key exam topic, including configuring interactive widgets.
