Assuming a standard time zone across the environment, what syntax will always return ewnts from between 2:00am and 5:00am?
Correct Answer:B
To always return events from between 2:00 AM and 5:00 AM, assuming a standard time zone across the environment, the correct Splunk search syntax is earliest=-2h@h AND latest=-5h@h (Option B). This syntax uses relative time modifiers to specify a range starting 2 hours ago from the current hour (-2h@h) and ending 5 hours ago from the current hour (-5h@h), effectively capturing the desired time window.
What happens to panels with post-processing searches when their base search Is refreshed?
Correct Answer:C
When the base search of a dashboard panel with post-processing searches is refreshed, the panels with these post-processing searches are refreshed automatically (Option C). Post-processing searches inherit the scope and results of the base search, and when the base search is updated or rerun, the post-processed results are recalculated to reflect the latest data.
What command is used la compute find write summary statistic, to a new field in the event results?
Correct Answer:C
The eventstats command in Splunk is used to compute and add summary statistics to all events in the search results, similar to the stats command, but without grouping the results into a single event(Option C). This command adds the computed summary statistics as new fields to each event, allowing those fields to be used in subsequent search operations or for display purposes. Unlike the transaction command, which groups events into transactions, eventstats retains individual events while enriching them with statistical information.
How can a lookup be referenced in an alert?
Correct Answer:C
To reference a lookup in an alert in Splunk, you would run a search that uses a lookup and then save that search as an alert (Option C). This method integrates the lookup within the search logic, and when the search conditions meet the alert's trigger conditions, the alert is activated. This approach allows the alert to leverage the enriched data provided by the lookup for more accurate and informative alerting.
