Splunk Enterprise Certified Admin Practice Test

Which Splunk component is responsible for receiving data from forwarders?

1. Search Head

2. Indexer

3. Heavy Forwarder

4. Deployment Server

The correct answer is: Indexer

The indexer is the Splunk component that plays a crucial role in the data ingestion pipeline. Specifically, its primary responsibility is to receive data from forwarders, which are systems designed to send log data and other information to Splunk for processing and analysis. Once the data reaches the indexer, it is indexed, making it searchable and available for reporting and various analytical functions. The indexer not only stores and indexes the incoming data but also prepares it for search, optimizing the way data queries are performed within the Splunk environment. This process entails parsing, transforming, and storing data in a format that is efficient for quick retrieval and analysis. Understanding the indexer's function is fundamental for managing data flow within a Splunk deployment, as it sits as a central piece in the data ingestion architecture. The other components, while critical in their own right, serve different purposes—such as the search head, which is responsible for executing user searches against the indexed data, or the heavy forwarder, which can also index data but is primarily involved in sending data to the indexer. Meanwhile, the deployment server is tasked with managing configuration for forwarders and deploying apps or updates across distributed Splunk components.
