Lab Challenge	Designing a DNS Namespace

Exercise 12.1	Designing a DNS Namespace
Overview
	Your firm is launching a new division, which will have its own DNS namespace, and your first task is to design that namespace by specifying appropriate domain and host names for the computers in the division.
Mindset	Why is it practical and necessary to have a policy in place for the naming of your organization- domains and hosts?
Completion time	20 minutes

2.	On the worksheet shown in Figure 12-1 andin your Lab 12 worksheet file, write the domain names and the fully qualified domain names you have selected for the computers in the appropriate spaces.

Lab Challenge	Remote DNS Administration
Overview
	To complete this challenge, you must configure SVR-MBR-C to manage the DNS server running on SVR-DC-A using the DNS console.
Completion time	10 minutes

List the steps you took to configure SVR-MBR-C and take a screen shot of the Connect to DNS Server dialog box, by pressing Alt+Prt Scr, and then paste the resulting images into the Lab 12 worksheet file in the page provided by pressing Ctrl+V.

Exercise 12.2	Creating a DNS Zone
Overview
	The zone is the administrative division that DNS servers use to separate domains. The first step in implementing the DNS namespace you designed is to create a zone representing your root domain.
Mindset	What is the relationship between DNS zones and DNS domains?
Completion time	10 minutes

Question 1	Why is a zone for the root domain of your DNS namespace already present in the Forward Lookup Zones folder?




Question 2	What resource records appear in the new zone you created by default?






Exercise 12.3	Creating DNS Domains
Overview
	A single zone on a DNS server can encompass multiple domains, as long as the domains are contiguous. In this exercise, you create the departmental domains you specified in your namespace design.
Mindset	What is the difference between creating a second-level domain and a third-level domain?
Completion time	10 minutes

Question 3	What resource records appear in the new domains you created by default?





Exercise 12.4	Creating DNS Resource Records
Overview
	Now that you have created the zones and domains for your namespace, you can begin to populate them with the resource records that the DNS server uses to resolve host names into IP addresses.
Mindset	What good are zones and domains without resource records?
Completion time	20 minutes

Question 4	What must you do before you can select the Create associated pointer (PTR) record checkbox in the New Host dialog box?




9.	Take a screen shot of the DNS Manager console, showing the resource records you created in the Human Resources domain, by pressing Alt+Prt Scr, and then paste the resulting image into the Lab 12 worksheet file in the page provided by pressing Ctrl+V.

Lab Challenge	Using Reverse Name Resolution
Overview
	Reverse name resolution is when a resolver sends an IP address to a DNS server and receives a host name in return, rather than sending a host name and receiving an IP address.
Completion time	20 minutes

	To complete this challenge, you must configure the DNS server on SVR-DC-A to perform reverse name resolutions for all of the resource records you created in Exercise 12.4. 
	List the basic tasks you performed to complete the challenge and then take a screen shot of the DNS Manager console, showing the elements you created during the challenge, by pressing Alt+Prt Scr, and then paste the resulting image into the Lab 12 worksheet file in the page provided by pressing Ctrl+V.
