Splunk Core Certified User Practice Exam

Which of the following can be sources of external data used by a Lookup?

1. Only internal data

2. Scripts and CSV files

3. Geospatial data only

4. Only structured database files

The correct answer is: Scripts and CSV files

The correct response highlights that Lookups in Splunk can utilize various forms of external data, specifically scripts and CSV files. This is important because Lookups are designed to enhance Splunk's existing data by providing additional context that can improve search results and insights. CSV files are commonly used because they allow for the organization of data in a structured format that Splunk can easily interpret and align with existing event data. When incorporated into searches, these CSV files can provide supplementary details about events, allowing for enriched data analysis. Scripts can also serve as a source of external data for Lookups. When a script is executed, it can return data in a structured format, which Splunk can integrate seamlessly into its search capabilities. This flexibility allows users to both automate data retrieval processes and customize how data is pulled into their Splunk environment. In contrast, internal data refers to the data that is ingested directly into Splunk from logs, events, and other sources already being monitored, which is not what Lookups are designed to address. Likewise, options focused solely on geospatial data or structured database files limit the scope of external data sources, as Lookups can engage a broader range of data types, not restricted to just one category.
