Final answer:
The statement that is not true about the Splunk Cloud REST API is that ingestion applications and add-ons do not have data parsing capabilities because they are designed to add such capabilities. (option 4)
Step-by-step explanation:
The Splunk Cloud REST API is not true is the fourth option: Splunk Cloud REST API ingestion applications and add-ons do not have data parsing capabilities. This statement is inaccurate because the main functionality of these applications and addons is to add data parsing and management capabilities to Splunk Cloud deployments.
To address the statements given:
Splunk Cloud REST API ingestion applications and add-ons are often modified from their on-premises versions to comply with Splunk Cloud's security and operational protocols. This is necessary to adapt to the managed service environment that Splunk Cloud offers.
Indeed, these applications and add-ons serve to enhance functionalities within a Splunk Cloud deployment, allowing for more specialized processing or integration with external systems.
For Splunk Cloud deployments, especially in the Classic experience, there might be options to install certain elements on an IDM (Intermediate Data Manager), indexers, or search heads as specified by Splunk's architecture and compatibility guidelines.
The incorrect statement suggests these applications and add-ons lack data parsing capabilities. In truth, data parsing is a core feature, as they are designed to help ingest and process data for analysis within Splunk Cloud.
