Splunk Fundamentals 1 Practice Exam

The primary function of an indexer in Splunk is to store and make data searchable. An indexer processes incoming data by indexing it, which means it organizes and stores data in such a way that it can be efficiently retrieved when users perform searches. This process involves transforming raw data into searchable events and creating an index that allows for fast querying. While visualization is an important part of using Splunk, it's typically performed by the search head rather than the indexer itself. Collecting machine data is primarily the role of forwarders, which relay the data to the indexer for processing. Managing user roles falls under the responsibilities of a different component, focusing on permissions and access control within Splunk, which is not related to the core indexing function.
