Which component of DSP uses REST API, HEC, UF?

The correct answer identifies input connectors as the component of DSP that utilizes REST API, HEC (HTTP Event Collector), and UF (Universal Forwarder). Input connectors are essential for receiving data from various sources into the Splunk environment, which is where these methods come into play.

REST API allows for easy integration and communication with external data sources, enabling the ingestion of data directly to the Splunk platform. The HTTP Event Collector is specifically designed to streamline data ingestion using HTTP requests, providing a straightforward way to send event data. The Universal Forwarder, on the other hand, acts as a lightweight agent that collects and forwards logs and metrics to the Splunk indexers, ensuring real-time data streaming.

These tools and methods are critical for feeding data into Splunk, which is why input connectors are directly associated with them. This highlights their role in expanding the ways data can be ingested into Splunk, making it essential for effective data handling in a cloud environment.
