The answer is a misconfiguration in props.conf for the intended sourcetype. When an automatic lookup works manually with the lookup command but fails at index time, the problem is almost always in the props.conf configuration—specifically, the TRANSFORMS directive is either missing, pointing to the wrong sourcetype like 'web_access', or has incorrect syntax. This is because automatic lookups require a transforms.conf stanza to define the lookup, and a props.conf stanza that correctly associates that transform with the exact sourcetype being indexed; if the sourcetype name in props.conf doesn’t match the data’s sourcetype, Splunk never applies the enrichment. On the SPLK-1002 exam, this tests your understanding of index-time field extraction versus search-time lookup commands, and the common trap is assuming a working manual lookup guarantees automatic enrichment. Remember the mnemonic: “Manual works, auto fails? Check your props and transforms trails.”
SPLK-1002 Using Fields and Lookups Practice Question
This SPLK-1002 practice question tests your understanding of using fields and lookups. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company uses Splunk to monitor web server logs. They have a lookup table that maps IP addresses to geographic locations (city, country). The lookup is defined as a CSV file with fields: ip, city, country. The lookup definition is named 'geo'. The team wants to automatically add city and country to every web event at index time, so that all future searches have this enrichment without adding the lookup command. The team tries to set up an automatic lookup in props.conf for the sourcetype 'web_access', but the city and country fields still do not appear in the events. They verify that the lookup file exists and that the lookup definition works when used manually with the lookup command. What is the most likely cause of the automatic lookup not working?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The automatic lookup definition in props.conf is not correctly configured for the intended sourcetype
Option D is correct because the automatic lookup definition in props.conf must be correctly configured for the intended sourcetype. The most common misconfiguration is specifying the wrong sourcetype or incorrect syntax in the TRANSFORMS directive, which prevents the lookup from being applied at index time. Since the lookup works manually, the issue is with the props.conf configuration, not the lookup file or definition itself.
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.
✗
Index-time lookups are not supported; enrichment can only be done at search time
Why it's wrong here
Splunk does support index-time lookups via automatic lookups in props.conf, though search-time is more common.
✗
The lookup file must be in KV Store format for index-time lookups
Why it's wrong here
CSV files are acceptable for index-time lookups.
✗
The lookup must be invoked with the 'lookup' command in the search to populate the fields
Why it's wrong here
Automatic lookups are designed to work without explicit commands.
✓
The automatic lookup definition in props.conf is not correctly configured for the intended sourcetype
Why this is correct
If the props.conf stanza does not match the sourcetype, the lookup will not be applied.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume automatic lookups work identically to search-time lookups, but they require explicit configuration in props.conf and transforms.conf, and any syntax error or sourcetype mismatch will silently fail.

Detailed technical explanation
How to think about this question
Index-time lookups in Splunk are implemented using the TRANSFORMS directive in props.conf, which references a transform in transforms.conf that specifies the lookup table and fields to add. The lookup file must be placed in the correct directory (e.g., $SPLUNK_HOME/etc/system/lookups or an app's lookups folder) and the transform must define the correct input and output fields. A common pitfall is forgetting to restart Splunk after modifying props.conf or transforms.conf, as these changes are not picked up dynamically.

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.
