Final answer:
The default script that comes with a Splunk deployment is the 'search' script, which is essential for querying and analyzing indexed data within the platform.
Step-by-step explanation:
The default script that comes with a Splunk deployment is search. Splunk is a powerful platform for searching, monitoring, and analyzing machine-generated data, which makes the search functionality integral to its operation. The search script is used to retrieve data from the indexes in Splunk, making it possible for users to query their data and derive insights. While other scripts such as input, output, and lookup also play important roles in Splunk, the search script is a default part of the Splunk Search & Reporting application, commonly known as the Search app. Its primary function is to navigate through the indexed data and perform searches to help users analyze their data. This search script is a key feature for creating searches, reports, and dashboards, making it fundamental to the Splunk environment.
