Which of the following is correct in regard to configuring a Universal Forwarder as an...

Configuring a Universal Forwarder (UF) as an Intermediate Forwarder involves making changes to its configuration to allow it to receive data from other forwarders before sending it to indexers.

D. It is only possible to make this change directly in configuration files or via a deployment app: This is the correct answer. Configuring a Universal Forwarder as an Intermediate Forwarder is done by editing the configuration files directly (like outputs.conf), or by deploying a pre-configured app via a deployment server. The Splunk Web UI (Management Console) does not provide an interface for configuring a Universal Forwarder as an Intermediate Forwarder.

A. This can only be turned on using the Settings > Forwarding and Receiving menu in Splunk Web/UI: Incorrect, as this applies to Heavy Forwarders, not Universal Forwarders.

B. The configuration changes can be made using Splunk Web, CLI, directly in configuration files, or via a deployment app: Incorrect, the Splunk Web UI is not used for configuring Universal Forwarders.

C. The configuration changes can be made using CLI, directly in configuration files, or via a deployment app: While CLI could be used for certain configurations, the specific Intermediate Forwarder setup is typically done via configuration files or deployment apps.
