Which of the following is NOT a type of Forwarder in Splunk?

In Splunk, forwarders are components that send data from various sources to indexers for processing. There are two main types of forwarders: the Universal Forwarder and the Heavy Forwarder. The Universal Forwarder is a lightweight, dedicated agent designed for efficient data forwarding with minimal resource utilization, while the Heavy Forwarder can perform data processing, such as rich data transformation and routing, before sending data to indexers.

The term "Light Forwarder" is not recognized as a standard type of forwarder within Splunk's architecture. Therefore, it correctly identifies the option that does not exist as an official category of forwarder in Splunk.

The Single Instance Forwarder is sometimes informally referred to; however, this term refers to instances where a Splunk instance acts both as a forwarder and an indexer, and it is not an official term like Universal Forwarder or Heavy Forwarder. Thus, the identification of a "Light Forwarder" as a non-existent type reinforces the understanding of Splunk’s categorization of forwarders.
