Quick Answer
The correct answer includes four true statements about fields and lookups, with the key being that lookups enrich events by matching a field in your data to a field in an external table, such as a CSV file or KV store. This enrichment process is fundamental to the Splunk Core Certified User SPLK-1002 exam, which tests your ability to use the `| lookup` command for adding context to raw events and the `| inputlookup` command for loading an entire lookup file into the search pipeline for direct inspection or aggregation. A common trap is confusing `| lookup` with `| inputlookup`—remember that `| lookup` appends fields to existing events, while `| inputlookup` treats the lookup file itself as the event source. Additionally, geospatial lookups require latitude and longitude coordinates and are paired with the `| geom` command for map visualizations. For the exam, a solid memory tip is: “Lookup enriches, inputlookup replaces”—the former adds data to your events, the latter turns the lookup into your search results.

Correct answer & explanation
✓
A lookup table can be used to add fields to events based on a match between a field in the event and a field in the lookup file.
The first option is correct because lookup tables in Splunk allow you to add fields to events by matching a field in the event with a field in the lookup file, enriching the data. The second option is correct because the `| lookup` command supports both CSV files and KV store collections, enabling flexible data enrichment. The fourth option is correct because geospatial lookups require latitude and longitude coordinates and are used with the `| geom` command for map visualizations. The fifth option is correct because `| inputlookup` loads the entire lookup file into search results, allowing direct inspection or aggregation of lookup data.
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 misconception that `| rex` extracted fields are automatically added to the field sidebar and searchable without additional configuration, but in reality they are transient within the search pipeline unless explicitly persisted.
Detailed technical explanation
How to think about this question
Under the hood, lookups in Splunk are implemented as search-time operations that use in-memory hash tables for CSV lookups or KV store lookups via the KV Store REST API, which can handle larger datasets. The `| rex` command performs regex extraction at search time, but extracted fields are only available within the search pipeline unless explicitly promoted via `| fields` or index-time extraction in transforms.conf. Geospatial lookups rely on the `| geom` command to render map tiles, and the lookup file must include latitude and longitude fields in decimal degrees format (e.g., WGS84).
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.
