You want to create a timechart showing the average response time by host, but you only want to see data for the last 7 days. How do you handle missing time buckets?
A Splunk administrator is troubleshooting a dashboard that uses the timechart command to display average CPU usage per host. The search returns results, but the chart shows a single line labeled 'ALL' instead of separate lines for each host. The search is: index=os sourcetype=cpu | timechart avg(cpu_usage) BY host. What is the most likely cause?
A security analyst needs to identify source IP addresses that have triggered more than 10 failed login events within a single hour, but the events arrive out of order and some hours have no events at all. The analyst wants a row for every hour in the search range, even hours with zero failed logins, so gaps are visible in the report. Which command should be used to produce this result?
A Splunk user needs to display the top 10 source IP addresses by number of failed login attempts, but also wants to see the percentage of total failed logins that each IP represents. Which command should be used to achieve this in one step?
A security analyst runs a search that returns web access logs with fields clientip, status, and bytes. They need to produce a table where each row shows a clientip, the total number of requests from that clientip, and the total bytes transferred by that clientip, but they also need to retain the original status field for each event for later filtering. Which command should they use?
A Splunk power user is analyzing web server logs and needs to create a report that shows the top 5 referring domains for each HTTP status code. The user wants to use a single search that returns a table with columns for status, referer_domain, and count, sorted by status and then by count descending. Which TWO commands are essential to achieve this? (Choose two.)
An administrator is building a search to correlate authentication failures with subsequent successful logins from the same user. The base search returns events with fields user, action, and _time.

A Splunk user has a search that returns events with a field named 'duration' in milliseconds. The user wants to display the duration in a more readable format, such as '1.5s' or '2m 30s', without changing the underlying numeric value used for calculations. Which command should the user employ to create a new field called 'readable_duration' that contains the formatted string?
A Splunk power user is working with a dataset that contains a field named 'product_id' and a field named 'product_name'. The user needs to create a new field that combines these two fields into a single string in the format 'product_id: product_name', and also needs to ensure that if either field is null, the combined field shows 'Unknown' instead of a partial string. Which two eval expressions will correctly produce the desired combined field? (Choose two.)
A Splunk power user runs a search that returns a field named duration_ms with values such as 1250 and 3400. They need to display this field in a table as a three-digit decimal number of seconds, rounded to two decimal places, without altering the underlying events. Which command should they use?
A Splunk power user has a search that returns events with a field named status_code. They need to replace every occurrence of the value 404 with Not Found and every occurrence of 500 with Server Error in the displayed results, while leaving all other values unchanged. Which command accomplishes this with the least effort?
A Splunk power user is preparing a report and needs to rename the field src_ip to Source Address and the field dest_ip to Destination Address in the final results, without changing the underlying field values. The user also wants to ensure that if either field is missing, the search does not fail but simply omits the renamed field. Which two commands can achieve the renaming? (Choose two.)
A Splunk power user has a search that returns a field named product_id containing values like 1001, 1002, and 1003. They need to add a new field named product_category that maps 1001 to Hardware, 1002 to Software, and 1003 to Services, and should be Unknown for any other product_id. Which command should they use?
A Splunk power user needs to display a table of web access logs where the status field is shown as either Success or Failure based on whether the status code is less than 400 or not. The user also wants to ensure that the original status field remains available for further calculations later in the search. Which command should they use?
A security analyst needs to correlate failed login events with subsequent successful logins from the same source IP within a 10-minute window. The raw events contain src_ip and action fields but no session identifier. Which Splunk transforming command should the analyst use to group these events into sessions based on time proximity?
A security analyst needs to enrich raw firewall logs by attaching the matching department name from a lookup table. The lookup table contains department IDs, and the firewall logs contain a field called dept_id. The analyst wants to add the department name to each event without discarding events that have no matching department ID. Which command should be used?
A Splunk administrator is building a dashboard panel that must show the total number of events per sourcetype and also include a column showing what percentage each sourcetype contributes to the overall event count. The search already uses stats count by sourcetype. Which approach will add the percentage column correctly in a single search?
A Splunk power user needs to calculate the total number of events per sourcetype and include a column that shows the percentage of total events each sourcetype represents. The search should return a table with sourcetype, count, and percentage. Which sequence of commands achieves this?
