I am setting up Jamf for the first time in my Org. We are connecting with Azure AD. I have my jump start in two weeks and I have a little confusion around if "my AD is externally facing" and if not "I need to set up Jamf Infrastructure Manager" before the Jump Start. I am not a networking guru and I do not want to look dumb to my team so looking to bring a little more knowledge around this to my first meeting about this on Monday. Can someone help?
