B.To group the results by one or more fields (Correct) Explanation by-clause Syntax: by <field-list> Description: Fields to group by. Example: BY addr, port Example: BY host
Which command is used to review the contents of a specified static lookup file? A.outputlookup B.inputlookup C.csvlookup D.lookup

When an alert action is configured to run a script, Splunk must be able to locate the script. Which is one of the directories Splunk will look in to find the script? A.$SPLUNK_HOME/etc/scripts B.$SPLUNK_HOME/bin/etc/scripts C.$SPLUNK_HOME/bin/scripts D.$SPLUNK_HOME/etc/scripts/bin
C.$SPLUNK_HOME/bin/scripts (Correct) Explanation If you have Splunk Enterprise, you can configure an alert to run a shell script or batch file when the alert triggers. The script or batch file that an alert triggers must be at either of the following locations: $SPLUNK_HOME/bin/scripts $SPLUNK_HOME/etc/apps/<AppName>/bin/scripts Specify an absolute path whenever a path is needed. If you use relative paths, it is important to remember that they are rooted in the Search and Reporting app's bin folder.

A.Click Selected Fields and select the field to add it to Interesting Fields B.Click Interesting Fields and select the field to add it to Selected Fields C.Click All Fields and select the field to add it to Selected Fields D.This scenario isn't possible because all fields returned from a search always appear in the fields sidebar

What must be done in order to use a lookup table in Splunk? A.The lookup file must be uploaded to the etc/apps/lookups folder for automatic ingestion B.The contents of the lookup file must be copied and pasted into the search bar C.The lookup file must be uploaded to Splunk and a lookup definition must be created D.The lookup must be configured to run automatically
C.The lookup file must be uploaded to Splunk and a lookup definition must be created (Correct) Explanation Creating a Lookup Upload the file required for the lookup(Lookup table files are files that contain a lookup table. A standard lookup pulls fields out of this table and adds them to your events when corresponding fields in the table are matched in your events. ) Define the lookup type (lookup defination-A lookup definition provides a lookup name and a path to find the lookup table. Lookup definitions can include extra settings such as matching rules, or restrictions on the fields that the lookup is allowed to match. One lookup table can have multiple lookup definitions. All lookup types require a lookup definition. After you create a lookup definition you can invoke the lookup in a search with the lookup command. ) Optionally, configure the lookup to run automatically (Use automatic lookups to apply a lookup to all searches at search time. After you define an automatic lookup for a lookup definition, you do not need to manually invoke it in searches with the lookup command.)
Which stats command function provides a count of how many unique values exist for a given field in the result set? A.count(field) B.count-by(field) C.dc(field) D.distinct-count(field)
C.dc(field) (Correct) Explanation distinct_count, dc - returns a count of unique values for a given field

[BY field-list] Here stats is a command, count is a function and vender_action is field. count returns the number of matching events based on the current search criteria Scenario Use the as clause to rename the count field
To specify a beginning and an ending for a time range, use earliest and latest
Examples: earliest=-h looks back one hour earliest=-2d@d latest=@d looks back from two days ago, upto the beginning of the day.
