How do I learn Splunk administration?

Had an old coworker hit me up a week ago. He took a job as a SOC analyst where part of his job is going to be supporting Splunk. He's a smart guy but Splunk is more complex than it looks. Given I've also been asked a few times on how to certify on Splunk Admin I thought I might as well break down and start a video series on Splunk Administration.

I produced two videos to help him on his journey and I hope they help you.

Install of Splunk Enterprise on CentOS7, VirtualBox and firewalld
