Splunk Enterprise Certified Admin Practice Test

Which instance contains a local fishbucket in a typical Splunk environment with a Universal Forwarder, Indexer, and Search Head?

1. Universal Forwarder

2. Indexer

3. Search Head

4. Each instance

The correct answer is: Each instance

In a typical Splunk environment, each instance plays a specific role in the data pipeline, and the local fishbucket is a crucial concept associated with how Splunk tracks which files have been read by the forwarders. The local fishbucket is a data structure that helps the Universal Forwarder keep track of the files it has already processed. When data is ingested, the forwarder writes an entry for each file into the fishbucket. This entry includes information such as the file path, the last read position, and the file's unique identifier. This prevents the forwarder from sending duplicate data to the Indexer by ensuring that only new data is forwarded during subsequent read operations. While the Universal Forwarder directly maintains the local fishbucket, the Indexer may also have its own implementation for managing indexed data but doesn’t manage the fishbucket for incoming data from forwarders. The Search Head does not have a fishbucket since it doesn't handle inbound data but rather interacts with data stored in the Indexers for search queries. Therefore, in a Splunk environment with a Universal Forwarder, Indexer, and Search Head, each instance indeed has its own functionality related to the data flow and tracking, but when specifically addressing the local fishbucket, it is predominantly
