Splunk SPLK-1002 Practice Test 2

Which of the following statements describes this search?
sourcetype=access_combined I transaction JSESSIONID | timechart avg (duration)
This search uses the transaction command to group events that share a common value for JSESSIONID into transactions1.The transaction command assigns a duration field to each transaction, which is the difference between the latest and earliest timestamps of the events in the transaction1.The search then uses the timechart command to create a time-series chart of the average duration of each transaction1. Therefore, option A is correct because it describes the search accurately. Option B is incorrect because the search does not use the stats command or the pause field.Option C is incorrect because the transaction command does not require the startswith and endswith options, although they can be used to specify how to identify the beginning and end of a transaction1.Option D is incorrect because the transaction command does not have to be the last command in the search pipeline, although it is often used near the end of a search1.
