- A
transaction sessionid
Why wrong: transaction sessionid groups events by session ID but imposes no time constraint, so it may include events far apart in time, failing the 5-second window requirement.
- B
transaction sessionid maxspan=5s
transaction sessionid maxspan=5s correctly groups events by session ID and limits the time span between first and last event to 5 seconds, meeting the requirement.
- C
join type=inner sessionid [search index=db]
Why wrong: join type=inner sessionid [search index=db] is for joining results from two searches, not for correlating events from different data sources within a time window.
- D
append [search index=db]
Why wrong: append [search index=db] simply appends results, with no correlation logic.
Question 366 of 500
How to Correlate Events from Different Sources Using the Transaction Command
This SPLK-1003 practice question tests your understanding of transactions and event correlation. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. A key principle to apply: transaction. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An analyst needs to correlate events from two different data sources (web logs and database logs) based on a common session ID. The events occur within a short time window of 5 seconds. Which command is most appropriate?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"which command"Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
transaction sessionid maxspan=5s
The transaction command groups events sharing a common field, but without additional options it lacks time boundaries. Option B uses maxspan=5s to enforce that only events within 5 seconds of each other are grouped, which directly matches the requirement. Options C and D (join and append) are not designed for correlating across data sources based on a common field within a time window. Therefore, option B is the most appropriate.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates often overlook the maxspan argument and assume that a basic transaction command enforces a time boundary, but without maxspan there is no guarantee events are within the required window.

How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
