Dear KodeKloud,
Today I was attempting Jenkins Level 1 Test and found interesting situation. In question 5 it was asked to install Mailer plugin and disable it, I did it, after some question later it was asked to install Git and GitLab plugins, which enabled back Mailer plugin. Ofcource I found it when I pushed end exam and validation failed Mailer plugin question. I went back to Jenkins to disable again Mailer plugin, at it’s not possible, because there is dependencies with Git plugins which uses mailer, so to get green all questions I had to disable Git and GitLab plugins, otherwise it was not possible to disable mailer.
