Splunk Enterprise Certified Admin 2026 – 400 Free Practice Questions to Pass the Exam

To verify if the forwarder is successfully sending data to the indexer, the correct method involves monitoring the continuous output of the `splunkd.log` using the `tail -f` command combined with specific grep filtering. This command allows you to actively watch the log file for real-time updates, thereby providing immediate visibility into the data transfer processes.

Utilizing `egrep` allows you to filter the log entries for multiple patterns, in this case, 'TcpOutputProc' and 'TcpOutputFd'. The 'TcpOutputProc' refers to the process responsible for managing the TCP connections used to send data to the indexer, while 'TcpOutputFd' typically indicates the file descriptor numbers associated with those TCP connections. Seeing these entries confirms that the forwarder is attempting to transmit data and provides insights into the status of these connections.

Other options do not effectively provide the same real-time monitoring capability combined with comprehensive filtering. For instance, using `cat` instead of `tail -f` lacks the ability to show live updates, which is crucial for immediate troubleshooting. Moreover, limiting the grep command to just 'TcpOutputProc' would miss out on pertinent information provided by 'TcpOutputFd'. The approach taken in the correct answer combines both real
