The internal Splunk authentication will take precedence over any external schemes, such as LDAP. This means that if a username exists in both $SPLUNK_HOME/etc/passwd and LDAP, the Splunk platform will attempt to log in the user using the native authentication first. If the authentication fails, and the failure is not due to a nonexistent local account, then the platform will not attempt to use LDAP to log in. If the failure is due to a nonexistent local account, then the Splunk platform will attempt a login using the LDAP authentication scheme. References:

 A [script://] input sends data to a Splunk forwarder using the standard output (STDOUT) and standard error (STDERR) streams of the script. A [script://] input is a type of scripted input that runs an executable script on a Splunk forwarder and indexes the data that the script outputs to STDOUT or STDERR. The script can be written in any scripting language, such as Python, Perl, or shell, and it can perform various tasks, such as querying APIs, databases, or remote data interfaces, and formatting the data for indexing. The Splunk forwarder launches the script at a specified interval and reads the data from its STDOUT or STDERR streams.

The other options are incorrect because they are not the methods that a [script://] input uses to send data to a Splunk forwarder. Option A is incorrect because UDP stream is not a method that a [script://] input uses, but rather a method that a network input uses to receive data from UDP ports. Option B is incorrect because TCP stream is not a method that a [script://] input uses, but rather a method that a network input uses to receive data from TCP ports. Option C is incorrect because temporary file is not a method that a [script://] input uses, but rather a method that a monitor input uses to read data from files or directories. References:
