Big thanks to LA for course videos and labs. Rilindo's online resources (in git) were a great intro to Puppetlabs docs as well.
For anyone taking the exam, read up on Puppet style guide and practice in the Enterprise Console. Expect questions on External CAs, 'puppet module', and hiera_include. Read and study the Puppet docs as much as possible and pay close attention to any "best practices" tips . The questions are really aimed at figuring out how well you understand the material.
