Splunk SPLK-1004 Exam Actual Questions

An event handler action in Splunk is an action that is triggered based on user interaction with dashboard elements. Running an eval statement based on a user clicking a value on a form (Option A) is an example of an event handler action. This capability allows dashboards to be interactive and dynamic, responding to user inputs or actions to modify displayed data, visuals, or other elements in real-time.

The fieldsummary command in Splunk generates statistical summaries of fields in the search results, including the count of events that contain the field (count) and the distinct count of field values (dc). These summaries provide insights into the prevalence and distribution of fields within the dataset, which can be valuable for understanding the data's structure and content. Standard deviation (stdev) and mean (mean) are not directly provided by fieldsummary but can be calculated using other commands like stats for fields that contain numerical data.

Cascading inputs in Splunk dashboards allow the selection in one input (like a dropdown, radio button, etc.) to determine the available options in the subsequent input, creating a dependent relationship between them. An event handler can be configured to reset subsequent inputs based on the selection made in a preceding input (Option A), ensuring that only relevant options are presented to the user as they make selections. This approach enhances the dashboard's usability by guiding the user through a logical flow of choices, where each selection refines the scope of the following options.

In Splunk dashboards, event annotations are used to add informative overlays on timeline visualizations to mark significant events. The required element attribute to define an event annotation within a dashboard panel is <search type='annotation'> (Option D). This attribute specifies that the search within this element is intended to generate annotations, which are then overlaid on the timeline based on the time and information provided by the search results.

Repeating JSON data structures within a single event in Splunk are extracted as multivalue fields (Option C). Multivalue fields allow a single field to contain multiple distinct values, which is common with JSON data structures that include arrays or repeated elements. Splunk's field extraction capabilities automatically recognize and parse these structures, allowing users to work with each value within the multivalue field for analysis and reporting
