Objective 1.2: Understand VMware NSX Architecture

Keep in mind, these are simply my reference notes that I used in conjunction with the official VCP6-NV course and the official product guides from VMware. For this Id stress taking a look at chapter 3 and 5 of the NSX design guide, which covers NSX Functional Components. Also using the vmware Hands on Labs or your own labs will help flesh out knowledge on the topics. Its good to review how these pieces interact with each other. For instance knowing what happens if a component of NSX dies or goes offline, and its impact, like will NSX Manager being powered off, disturb pushed DFW rules?
