True or False: Splunk Cloud Search Heads can search on-premise and Cloud indexers by default.

Splunk Cloud Search Heads are designed to primarily interact with Splunk Cloud indexers. By default, they do not have the capability to search on-premise indexers. This is due to the architecture of Splunk Cloud, which is built to operate in a securely isolated environment where cloud infrastructure is not directly accessible from on-premises resources without specific configurations or setups.

For a Search Head to access on-premise indexers, it would usually require additional configurations, such as setting up a hybrid environment that allows for such interactions, which are not standard practices. This isolation is implemented to maintain security and integrity within the cloud environment.

Thus, the answer is that it is false to say that Splunk Cloud Search Heads can automatically search across both on-premise and cloud indexers without any specific configuration.
