I just passed I and can not find the self learning option for II?? There should be an option to take it after finishing the first one. Yes I have an account with an MSSP so 2 is free for us.
Splunk Fundamentals 2 is only offered as an instructor-led lecture, with labs. There is no self-learning option. It is delivered in a virtual classroom, or you can arrange for an instructor at your site.
