SPLK-1001 Basic Searching and Transforming Commands Practice Question

Exhibit

index=weblogic sourcetype=accesslog
| rex "status=(?<status_code>\d+)"
| stats count by status_code
| where count > 100

Refer to the exhibit. An analyst runs this search and expects to see a table of status codes with their counts, filtered to those with count greater than 100. The search returns zero results even though there are many events. What is the most likely reason?

⚠ Common exam trap

Splunk often tests the misconception that a stats or where command is misordered, when the actual issue is a failed field extraction due to an incorrect regex pattern in rex.

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

The rex command is incorrectly extracting the status_code field.

The rex command is incorrectly extracting the status_code field because the regular expression pattern does not match the actual format of the status codes in the events. If the pattern is wrong or the field is not captured correctly, the stats command will not find any values for status_code, resulting in zero results even though events exist. The where command then filters on a field that doesn't exist or is null, returning no rows.

Answer analysis

Option-by-option breakdown

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

  • The sourcetype should be 'access_combined' instead.

    Why it's wrong here

    Not necessarily; sourcetype name may be correct.

  • The stats command should use 'values(status_code)' instead.

    Why it's wrong here

    That would return a list of values, not a count, and would not solve the zero results.

  • The rex command is incorrectly extracting the status_code field.

    Why this is correct

    If the pattern doesn't match, status_code is not extracted, leading to zero results when grouped.

  • The where command should be placed before the stats command.

    Why it's wrong here

    That would filter before count exists, not the issue.
