Splunk Enterprise Certified Admin Practice Test

Is it possible to use the host value instead of the DNS name or IP address for TCP input?

1. Yes, by setting connection_host to none

2. No, only DNS or IP address can be used

3. Only if the host is configured in the forwarder

4. Yes, but it requires additional configuration

The correct answer is: Yes, by setting connection_host to none

The host value can indeed be utilized instead of the DNS name or IP address for TCP input by configuring the connection_host setting. When you set connection_host to "none," you are instructing Splunk to not associate the incoming data with any specific host information derived from the DNS or the IP address. This enables the system to use the timestamp and source information from the incoming data itself. In practical scenarios, this configuration can help you manage data more efficiently by eliminating the need to resolve each incoming connection to a specific DNS or IP address, which may be particularly useful in environments where data comes from various unpredictable sources. Additional configurations are not necessary specifically for this function, as setting connection_host to none alone will achieve the desired behavior. However, it's important to be aware of the implications of this setting on data integrity and accuracy when analyzing logs in Splunk.
