SPLK-1003 Event filtering Practice Question

This SPLK-1003 practice question tests your understanding of advanced searching and statistics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: event filtering. 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.

A team uses a large index with many sourcetypes. They want to find events where the field "status" contains either "error" or "failure" (case-insensitive), and also ensure that "response_time" > 1000. Which search best optimizes performance?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

index=main | stats avg(response_time) as avg, count as cnt by category | where cnt>=100 | sort -avg | head 5

None of the provided options correctly implement the required search. The question asks for events where status contains 'error' or 'failure' (case-insensitive) and response_time > 1000. However, all options perform aggregation by category and ignore the status filter entirely. A correct search would use a pattern like: `index=main (status=*error* OR status=*failure*) response_time>1000`. None of the options filter events as required, so they are all incorrect.

Key principle: Event filtering

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • index=main | eventstats avg(response_time) as avg by category | stats count as cnt by category | where cnt>=100 | sort -avg | head 5

    Why it's wrong here

    This option uses eventstats and stats to compute average and count per category, but it does not filter events based on status or response_time. It also references 'avg' in a sort command after the where clause, which is not allowed.

  • index=main | top category | eval avg=avg(response_time) | where count>=100

    Why it's wrong here

    This option uses top category and then attempts to compute average with eval, but it does not filter events and has incorrect syntax (eval cannot compute avg on a field without aggregation).

  • index=main | stats avg(response_time) as avg by category | where cnt>=100 | sort -avg | head 5

    Why it's wrong here

    This option uses stats to compute average by category but does not include a count field, so the subsequent 'where cnt>=100' will fail because 'cnt' is not defined. No status filter is applied.

  • index=main | stats avg(response_time) as avg, count as cnt by category | where cnt>=100 | sort -avg | head 5

    Why this is correct

    This option computes both average and count per category correctly, but it still does not filter events by status or response_time, which is the primary requirement of the question.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap is that candidates may focus on optimizing aggregation performance and overlook that the stem's filtering conditions (status containing 'error'/'failure' and response_time>1000) are not addressed by any of the options. The question tests the ability to identify when options are mismatched to the query requirements.

Trap categories for this question

  • Command / output trap

    This option uses eventstats and stats to compute average and count per category, but it does not filter events based on status or response_time. It also references 'avg' in a sort command after the where clause, which is not allowed.

Detailed technical explanation

How to think about this question

The stats command in Splunk processes events in a single streaming pass, computing multiple aggregations (avg, count) per group without requiring separate subsearches or eventstats. For large indexes, this reduces memory and CPU overhead. The where clause after stats filters on the computed count, which is more efficient than filtering before aggregation because it avoids processing events that would be discarded later. Sorting by avg descending and limiting to head 5 further reduces data transfer to the search head.

KKey Concepts to Remember

  • Event filtering
  • Case-insensitive search
  • Combining conditions
  • Aggregation commands

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Real-world example

How this comes up in practice

A practitioner preparing for the SPLK-1003 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Event filtering Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
