SPLK-1002 Basic Searching and Transforming Commands Practice Question
This SPLK-1002 practice question tests your understanding of basic searching and transforming commands. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
The where command should be placed before the stats command.
Why it's wrong here
That would filter before count exists, not the issue.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
The rex command uses a named capturing group (?<field_name>regex) to extract fields. If the regex does not match the data (e.g., due to incorrect delimiters, whitespace, or field position), the field is not created or is null. The stats command then counts null values as zero, and the where count > 100 filters out those zeros. In real-world scenarios, common mistakes include forgetting to escape special characters or assuming a fixed field position when the log format varies.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
