Which command will join a Universal Forwarder to a deployment server?

A Splunk Universal Forwarder is configured as a deployment client by setting the deployment server polling address. The CLI command used for this is:

$SPLUNK_HOME/bin/splunk set deploy-poll < deployment_server > : < management_port >

The management port is usually 8089 unless it has been changed.

Example:

/splunk set deploy-poll deploymentserver.example.com:8089

This command tells the Universal Forwarder to poll the deployment server for apps and configuration updates.

Option B is incorrect because splunk join d.server is not a valid Splunk CLI command.

Option C is incorrect because set deploy-server is not the correct CLI syntax for configuring a deployment client.

Option D is incorrect because join deploy-poll is not a valid Splunk CLI command.
