What command is utilized to display the default host name for all data inputs?

1. splunk show servername

2. splunk show default-hostname

3. splunk default-hostname show

4. splunk display hostname

The correct answer is: splunk show default-hostname

The command to display the default host name for all data inputs is 'splunk show default-hostname'. This command is specifically designed to query and show the default hostname that Splunk uses for data inputs. Understanding this command is important for proper configuration and management of data sources, as the host field is a crucial component in identifying the origin of the data within Splunk. The structure of the command indicates that it is an inquiry into the Splunk server's settings, where the focus is on retrieving specific configuration information related to the hostname. This is essential for users aiming to ensure that data is correctly attributed to the corresponding host when indexed in Splunk. Other options do not accurately reflect the correct syntax or context for retrieving the default host name. For instance, 'splunk show servername' suggests a different context related to the server's name but does not specifically address the default host name for data inputs. Similarly, 'splunk default-hostname show' and 'splunk display hostname' are not valid commands recognized by Splunk, which renders them ineffective for this purpose. Therefore, the command 'splunk show default-hostname' is the appropriate choice for displaying the default host name associated with data inputs in Splunk.
