- A
The events are not indexed.
Why wrong: If events are not indexed, they wouldn't appear in search results at all.
- B
The lookup command uses output_fields incorrectly.
Why wrong: Incorrect output_fields may cause no output, but typically would not cause empty fields.
- C
The lookup file has duplicate keys.
Why wrong: Duplicates would cause multiple matches, not empty values.
- D
The lookup field name in the event does not match the lookup key.
Mismatch prevents matching, resulting in no enrichment.

SPLK-1002 Using Fields and Lookups Practice Question
This SPLK-1002 practice question tests your understanding of using fields and lookups. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A search uses a lookup to enrich results with a field 'status'. After the lookup, some events have empty status values. The lookup file contains a mapping for all possible status codes. What is a likely reason for empty values?
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 lookup field name in the event does not match the lookup key.
Option D is correct because the lookup command matches a field in the event (the lookup key) against a field in the lookup file. If the field name in the event does not exactly match the lookup key field name in the lookup file, no match occurs, and the output field (e.g., 'status') remains empty. This is a common misconfiguration when the lookup key field is misspelled or has a different case.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Splunk often tests the distinction between a lookup that returns no match (empty values) versus a lookup that fails due to syntax or data issues, and candidates mistakenly blame duplicate keys or output_fields instead of recognizing a key field mismatch.
Trap categories for this question
Command / output trap
Incorrect output_fields may cause no output, but typically would not cause empty fields.
Detailed technical explanation
How to think about this question
The lookup command performs a left join-like operation: for each event, it searches the lookup file for a row where the key field matches the event's field value. If no match is found, the output fields are set to null (empty). This behavior is analogous to an SQL LEFT JOIN where the right table has no matching row. In Splunk, the lookup file is typically a CSV or KV store, and the key field must be an exact string match (case-sensitive by default).
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 practitioner preparing for the SPLK-1002 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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
