1) Chapter 8 Using Virtualization in Windows 12 Server

Class,

A huge portion of this chapter deals with virtualization in Windows server 2012 and it important that everyone has a solid understanding of this technology and what it does because as the technology has progressed it has moved more into a virtualized environment. The days of having data centers the size of a Walmart are over and consolidation seems to be the norm now a days. What is virtualization? What are the pros of using virtualization on a Windows Server?

2) Chapter 8 Hyper V

Class,

There has been a lot of pros that have been attributed to Hyper-V technology. Does anyone see any cons that would not want to use Hper-V? In what scenario would Hyper-V not work for your enviornment?

3) Chapter 8 Snapshots

Class,

Here’s a real world scenario. Have you built a server or installed on Operating system? It take you a few hours to install the O/S, install the proper drivers for the hardware and get all of the update installed on your machine. And for some unknown reason your server or computer just bombs and your lose everything and have to completely start over because you didn’t backup your O/S. Well hopefully talking about his subject will help with that. What is a Snapshot as it related to virtualization? What’s the benefit of a Snapshot? For those who have used a VM or worked in a VM environment this should be a familiar concept.

4) Chapter 8 Chapter Review

So the general idea im getting from chapter 8 is the overall benefit and use of Hyper-V. It discusses some important details about virtual networks and virtual hard disk. At the begining i did notice it mentions taking you thru the steps for two install types one is a full installation and the other is server core. A important note or detail i did pick up on is that you need to ensure that your server meets not only the hardware requirements but also the software requirements as well. The server core installation creates a operating system without a GUI shell according the the book. But something i liked about the server core installation was how it reduces the attack surface since few applications are running. This increases system availability and thereby reduces downtime.

5) Chapter 9 Subnetting

I also find revisiting the concepts of subnetting to be extremely helpful as I am quite a newbee to all of these ideas and to understand networking, subnetting is absolutely essential! I especially found the way in which they described subnetting in the reading to helpful for me because I work in a hotel. Subnetting a hotel with over 1000 rooms could be something like using the number 101(1=floor 1 and 01 =room 1) the first room on the second floor would be 201 and so on. Someone looking for room 321 would go to the 3rd floor room 21. In computer terms to find a host in a network the router would route the packet to the correct network portion of the address and than the correct host ID.

6) Chapter 10 DHCP

Class,

I’d like to expand the conversation about DHCP. When talking about DHCP, we throw around terms like static IP, dynamic and scope and really don’t fully understand what they really mean. I’d like for us to dissect the whole process and really see the importance of DHCP for us to get our information. How would you define a DHCP? What exactly does it do? What does a DHCP server do? What’s a static IP address and why is it important?

7) Supporting Activity DNS

For me to troubleshoot the problems, I’ll first reboot the server, most times the problem solves itself if nothing else works. The only issue that I can think that may happen with the DDNS is if the port isn’t functioning correctly, an example is that the DDNS is not launching error. Once the user enables the port and it is working properly, then a restart or firmware update should take place to fix the error. A problem that may occur to some users is the DDoS attack; this is due to DNS services outages and temporary disconnects the network. The DNS cache settings can negatively impact the users if DNS cache poisoning takes place, unauthorized domain names or IP addresses get inserted into the DNS cache. According to Mitchell (2017), DNS cache poisoning happens when computer viruses or other attacks added invalid DNS entries into the cache, users will then transfer to a different destination instead of the one he/she was trying to access.
