SPLK-1001 Splunk Basics and Interface Navigation Practice Question
A security team wants to add department info from an external CSV file to events containing user IDs. The CSV has columns 'userid' and 'department'. What is the correct configuration?
⚠ Common exam trap
Splunk often tests the distinction between using a lookup definition name versus a filename in the `lookup` command, and the trap here is that candidates mistakenly use the CSV filename directly (as in Option C) instead of the defined lookup name, or confuse `inputlookup` (which loads the file as events) with `lookup` (which enriches existing events).
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
✓
Define a lookup definition with userid as input field and department as output field, then use | lookup department_lookup userid OUTPUT department
It follows the proper Splunk workflow for enriching events with external data: first define a lookup definition that maps the CSV file's 'userid' as the input field and 'department' as the output field, then use the `| lookup` command with the lookup name (not the filename) to automatically match the userid field in each event and add the corresponding department. This approach is efficient and scalable, as it performs a field-based lookup without requiring a separate join or manual file reference.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Define a lookup definition, then use | inputlookup department.csv
Why it's wrong here
inputlookup loads the CSV as events, not as enrichment.
- ✓
Define a lookup definition with userid as input field and department as output field, then use | lookup department_lookup userid OUTPUT department
Why this is correct
This is the correct sequence: define lookup definition and use lookup command.
- ✗
Define a lookup table, then use | lookup department.csv userid OUTPUT department
Why it's wrong here
Lookup command requires a definition name, not a filename.
- ✗
Use | join userid with department.csv
Why it's wrong here
Join is inefficient and not intended for lookups.
