Exercise 1.2 Creating a Windows Server 2012 NLB Cluster Overview During this exercise, you will create the NLB Cluster using Server01 and Server02.

Completion time 15 minutes

Mindset Question: You have a website that must be fault tolerant, so you decide to use MOAC 70-412: Configuring Advanced Windows Server 2012 Services

Exercise 1.3 Configuring DNS Overview Users will need to find the clusters. Therefore, during this exercise, you will configure DNS resource records.

Mindset Question: There are two things still missing. First, you will need to install IIS, and deploy the websites on Server01 and Server02. So when you are ready to go live, what are the last steps needed so that users can reach the websites?

Exercise 1.4 Configuring Cluster Properties Overview Currently, the port rules allow all TCP and UDP ports. During this exercise, you will redefine the port rules for only the ports that you need. Completion time 10 minutes

Mindset Questions: As mentioned earlier, the cluster is meant to support a website. What ports will you need to support the websites?

Question What filtering mode is selected and what affinity is selected? 4 MOAC 70-412: Configuring Advanced Windows Server 2012 Services

Why would you need to use single affinity?

Question 5

Exercise 1.5 Managing the Cluster Nodes Overview You need to do maintenance on the nodes. At this time, you need to stop one of the nodes, and then bring the node back online.

What does drainstop do?

Question 6

2. Take a screen shot of the Network Load Balancing Manager by pressing Alt+Prt Scr and then paste it into your Lab 1 worksheet file in the page provided by pressing Ctrl+V.

LAB REVIEW QUESTIONS

1. In Exercise 1.1,when you installed NLB, was it a role or a feature?

2. In Exercise 1.2,what mode (multicast or unicast) should you use if you have two network cards?

3. In Exercise 1.2, if you did choose to use multicast mode, what MAC addresses are assigned to the NLB network adapter?

4. In Exercise 1.3,what is the advantage of using an alias resource record.

5. In Exercise 1.4,what filter mode would you select if you want one server to be the primary web server, and the other node wait until the primary server goes down.

6. In Exercise 1.5, what would happen if you do not use drainstop to stop a node?

Lab Challenge Upgrading a Cluster Overview To complete this challenge, you will describe how to upgrade a cluster running on Windows Server 2008 R2 to Windows Server 2012. Completion time 10 minutes MOAC 70-412: Configuring Advanced Windows Server 2012 Services

You have a NLB cluster running on two servers running Windows Server 2008 R2. What would you do to upgrade the cluster to Windows Server 2012?/
