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.
An administrator wants to add a lookup table that maps user IDs to department names. The lookup file is a CSV with columns `user_id` and `department`. To use this lookup in searches, what must be configured?
Define the lookup as a time-based lookup.
Why wrong: Not time-based.
Define the lookup table file in the transforms.conf with a search string.
Why wrong: transforms.conf defines lookup parameters.
Upload the CSV to Splunk and it automatically becomes available.
Why wrong: Requires explicit definition.
Define a lookup definition in props.conf and transforms.conf.
Standard configuration.
Answer choices
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 in props.conf and transforms.conf.
Option D is correct because to use a static CSV lookup in Splunk, you must first upload the file to the lookups directory, then define a lookup stanza in transforms.conf specifying the filename, and finally create a lookup definition in props.conf (or via the UI) to make it available for search commands like `lookup` or `inputlookup`. This two-step configuration ensures Splunk can locate the file and map the fields correctly.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Define the lookup as a time-based lookup.
Why it's wrong here
Not time-based.
Define the lookup table file in the transforms.conf with a search string.
Why it's wrong here
transforms.conf defines lookup parameters.
Upload the CSV to Splunk and it automatically becomes available.
Why it's wrong here
Requires explicit definition.
Define a lookup definition in props.conf and transforms.conf.
Why this is correct
Standard configuration.

Common exam traps
Splunk often tests the misconception that uploading a CSV file alone makes it usable as a lookup, but the trap here is that you must configure both transforms.conf and a lookup definition (props.conf or UI) to register the lookup for search-time use.
Detailed technical explanation
Under the hood, Splunk reads the CSV file from `$SPLUNK_HOME/etc/apps/<app>/lookups/` and uses the transforms.conf stanza to map the CSV columns to search-time fields. The lookup definition in props.conf (or the UI) ties the transforms.conf stanza name to a lookup name used in SPL commands. A subtle behavior: if the CSV file is updated, Splunk caches the file; you must either restart Splunk or use the `| lookup` command with `update_period` to refresh the data without restart.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
