1. vCenter Single Sign-On (SSO) for vSphere 7 Before we get started here, I just want to mention we’re about to learn about things like identity sources and how we can use these with the Vsphere client to get logged in. But starting in Vsphere 7, V Center supports federated authentication, and VMware is encouraging […]

1. The vSphere CPU Scheduler So, first off, we have a world. A world is simply a thread of execution inside an ESXi host. So a good example of a world would be a virtual CPU for a virtual machine. Each virtual CPU that I configure a virtual machine with is going to be a […]

1. 10.0 Addressing Networks with IPv6 In our last module, we got mathematical with IP version four. But the bad news is, with IPV-4 addresses, we’re out. And we have to rely on services such as network address translation in order to keep using them. The good news is that IP Version 6 is coming […]

8. 9.7 The Need for Subnetting We know that the different classes of IP addresses in the class A, class B, and class C ranges have a default subnet mask. However, we might want to alter that subnet mask. And in this video, we want to take a look at a couple of reasons we […]

1. 9.0 Addressing Networks with IPv4 In addition to physical Mac addresses, our network devices need logical addresses in order to communicate on our network as well as out to the Internet. These logical addresses are called IP addresses. That’s short for Internet Protocol addresses. And we’ve got two versions: version four and version six. […]

1. 8.0 Demystifying Wireless Networks Our network is becoming increasingly congested as more smartphones, laptops, and other devices connect to the Internet of Things. We need to be super familiar with wireless LAN concepts, and that’s what we’re going to be doing in this module. Specifically, we’re going to be understanding how data is encoded […]

11. 7.10 STP Example In this video, we want to get some practise analysing a spanning tree topology and determining who is the route bridge, what are the root ports, what are the designated ports, and which ports are blocking. And I wish I had been exposed to this. Prior to my interview at Walt […]

1. 7.0 Using Ethernet Switches I’ve got a question for you. Do you know what’s at the other end of the Ethernet cable plugged into the back of your computer right now, assuming you have a wired connection and not a wireless connection? The other end of that cable is probably plugged into an Ethernet […]

10. 6.9 Punch-Down Blocks So far in this module, we’ve been talking about 66 blocks and 110 blocks as punch-down blocks that we might find in a wiring closet where we’re physically punching down building wiring into the conductors inside the punch-down blocks. But CompTIA wants us to know about a couple of extra punch-down […]

1. Storage Account – Data Archiving and Access Tiers So continuing on talking about business continuity, in this video, we’re going to talk about something a little different, and that’s the concept of data archiving. Now, data archiving is not the same as data backups, although you might want to keep your data backups for […]
