If a search contains a subsearch, what is the order of execution?
Correct Answer:B
In a Splunk search containing a subsearch, the inner subsearch executes first (Option B). The result of the subsearch is then passed to the outer search. This is because the outer search often depends on the results of the inner subsearch to complete its execution. For example, a subsearch might be used to identify a list of relevant terms or values which are then used by the outer search to filter or manipulate the main dataset.
Which of the following fields are provided by the fieldsummary command? (select all that apply)
Correct Answer:AD
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.
Which statement about the coalesce function is accurate?
Correct Answer:C
The coalesce function in Splunk is used to evaluate each argument in order and return the first non-null value. This function can be used within an eval expression to create a new field in the results set, which will contain the first non-null value from the list of fields provided as arguments to coalesce. This makes it particularly useful in situations where data may be missing or inconsistently populated across multiple fields, as it allows for a fallback mechanism to ensure that some value is always presented.
When running a search, which Splunk component retrieves the individual results?
Correct Answer:B
The Search head (Option B) in Splunk architecture is responsible for initiating and coordinating search activities across a distributed environment. When a search is run, the search head parses the search query, distributes the search tasks to the appropriate indexers (which hold the actual data), and then consolidates the results retrieved by the indexers. The search head is the component that interacts with the user, presenting the final search results
What type of drilldown passes a value from a user click into another dashboard or external page?
Correct Answer:D
Contextual drilldown (Option D) is the type of drilldown that allows passing a value from a user click (e.g., from a table row or chart element) into another dashboard or an external page. This feature enables the creation of interactive dashboards where clicking on a specific element dynamically updates another part of the dashboard or navigates to a different page with relevant information, using the clicked value as a context for the subsequent view.
Which of the following is not a common default time field?
Correct Answer:A
In Splunk, common default time fields include date_minute, date_year, and date_day, which represent the minute, year, and day parts of event timestamps, respectively. date_zone (Option A) is not recognized as a common default time field in Splunk. The platform typically uses fields like _time and various date_* fields for time-related information but does not use date_zone as a standard time field.
