Each lab in this manual requires that you answer inquiries. take screen shootings. and execute other activities that you will document in a worksheet named for the lab. such as Lab12_worksheet. docx. It is recommended that you use a USB flash thrust to hive away your worksheets. so you can subject them to your teacher for reappraisal. As you perform the exercisings in each lab. open the appropriate worksheet file. fill in the needed information. and salvage the file to your brassy thrust. After finishing this lab. you will be able to:
Design a DNS namespace

Estimated lab clip: 90 proceedingss
Exercise 12. 1
Planing a DNS Namespace
Your house is establishing a new division. which will hold its ain DNS namespace. and your first undertaking is to plan that namespace by stipulating appropriate sphere and host names for the computing machines in the division. Mindset
Why is it practical and necessary to hold a policy in topographic point for the naming of your organization’s spheres and hosts? Completion clip
1. Plan a DNS namespace for your organisation that conforms to the undermentioned guidelines. The root sphere name for the organisation is adatum. com. All of the extra spheres you create must be low-level to this sphere. The internal web must be in a different sphere from the external web.
The organisation consists of three internal divisions: Gross saless. Human Resources. and Production. Each division must be represented by a separate subdomain in the namespace. Each division has departmental waiters executing assorted functions and every bit many as 200 workstations. merely some of which are shown in the diagram. Your host names should place the map of each computing machine.
Three waiters on an external margin web host the company’s Internet services: Web. FTP. and e-mail. These waiters must be in the sphere adatum. com. 2. On the worksheet shown in Figure 12-1 and in your Lab 12 worksheet file. compose the sphere names and the to the full qualified sphere names you have selected for the computing machines in the appropriate infinites.

End of exercising.
Remote DNS Administration
To finish this challenge. you must configure SVR-MBR-C to pull off the DNS waiter running on SVR-DC-A utilizing the DNS console. Completion clip
List the stairss you took to configure SVR-MBR-C and take a screen shooting of the Connect to DNS Server duologue box. by pressing Alt+Prt Scr. and so glue the resulting images into the Lab 12 worksheet file in the page provided by pressing Ctrl+V. End of exercising. You can go forth the Windowss open for the following exercising.
Exercise 12. 2
Making a DNS Zone
The zone is the administrative division that DNS waiters use to divide spheres. The first measure in implementing the DNS namespace you designed is to make a zone stand foring your root sphere. Mindset
What is the relationship between DNS zones and DNS spheres? Completion clip
1. On SVR-MBR-C. in Server Manager. chink Tools & gt ; DNS. The DNS Manager console appears. 2. Expand the SVR-DC-A node and choose the Forward Lookup Zones booklet ( see Figure 12-2 ) .
The DNS Manager console
Why is a zone for the root sphere of your DNS namespace already present in the Forward Lookup Zones booklet?
3. Right-click the Forward Lookup Zones booklet and. from the context bill of fare. choice New Zone. The New Zone Wizard appears. 4. Click Next to short-circuit the Welcome page. The Zone Type page appears. 5. Leave the Primary Zone option and the Store the zone in Active Directory cheque box selected and click Next. The Active Directory Zone Replication Scope page appears.
6. Click Next to accept the default scene. The Zone Name page appears. 7. In the Zone name text box. type the internal sphere name from the diagram you created in Exercise 12. 1 and click Next. The Dynamic Update page appears. 8. Choose the Allow both nonsecure and unafraid dynamic updates option and chink Next. The Completing the New Zone Wizard page appears. 9. Click Finish. The new zone appears in the Forward Lookup Zones booklet in the console. Question 2
What resource records appear in the new zone you created by default?
End of exercising. You can go forth the Windowss open for the following exercising. Exercise 12. 3
Making DNS Domains
A individual zone on a DNS waiter can embrace multiple spheres. every bit long as the spheres are immediate. In this exercising. you create the departmental spheres you specified in your namespace design. Mentality
What is the difference between making a second-level sphere and a third-level sphere? Completion clip
1. On SVR-MBR-C. in the DNS Manager console. right-click the zone you created utilizing the internal sphere name from your namespace in Exercise 12. 2 and. from the context bill of fare. choice New Domain. The New DNS Domain duologue box appears. as shown in Figure 12-3.
The New DNS Domain duologue box
2. In the Type the new DNS sphere name text box. type the name of the Human Resources sphere you specified in your namespace design and chink OK. Note
When you create a sphere within a zone. you specify the name for the new sphere comparative to the zone name. For illustration. to make the hour. int. contoso. com sphere in the int. contoso. com zone. you would stipulate merely the hour name in the New DNS Domain duologue box.
3. Repeat steps 1 to 2 to make the spheres for the Gross saless and Production sections from your namespace design. Question 3
What resource records appear in the new spheres you created by default?
End of exercising. You can go forth the Windowss open for the following exercising.
Exercise 12. 4
Making DNS Resource Records
Now that you have created the zones and spheres for your namespace. you can get down to dwell them with the resource records that the DNS waiter uses to decide host names into IP references. Mindset
What good are zones and spheres without resource records?
1. On SVR-MBR-C. in the DNS Manager console. expand and right-click your root sphere zone ( adatum. com ) and. from the context bill of fare. choice New Host ( A or AAAA ) . The New Host duologue box appears. as shown in Figure 12-4.
The New Host duologue box
2. In the Name text box. type the host name of the Internet web waiter you specified in your namespace design. 3. In the IP Address text box. type 10. 0. 0. 10.
What must you make before you can choose the Create associated arrow ( PTR ) record cheque box in the New Host duologue box?
4. Click Add Host. A DNS message box appears. saying that the resource record was created. 5. Click OK. A new. clean Add Host duologue box appears.
6. Repeat steps 2 to 4 to make Host records for the Internet FTP and Internet e-mail waiters in your namespace design. utilizing the IP addresses 10. 0. 0. 11 and 10. 0. 0. 12. severally. 7. In the three spheres you created in Exercise 12. 3. create Host resource records for all of the staying computing machines in your namespace design. puting each computing machine within its appropriate subdomain ; Human Resources. Gross saless. or Production. utilizing the names you specified in your diagram and different IP references in the 10. 0. 0. 10 to 10. 0. 0. 30 scope. Note
For the intents of this exercising. the existent IP addresses you use when
making your resource records do non count. In an existent DNS deployment. you must either stipulate an appropriate IP reference for each host. based on the subnet to which the computing machine is connected. or rely on DHCP to make the resource records for the computing machines.
8. Click Done to shut the Add Host duologue box.
9. Take a screen shooting of the DNS Manager console. demoing the resource records you created in the Human Resources sphere. by pressing Alt+Prt Scr. and so glue the resulting image into the Lab 12 worksheet file in the page provided by pressing Ctrl+V. 10. Close the DNS Manager console.
End of exercising. You can go forth the Windowss open for the following exercising.
Lab Challenge Using Reverse Name Resolution
Reverse name declaration is when a resolver sends an IP reference to a DNS waiter and receives a host name in return. instead than directing a host name and having an IP reference. Completion clip
To finish this challenge. you must configure the DNS waiter on SVR-DC-A to execute contrary name declarations for all of the resource records you created in Exercise 12. 4. List the basic undertakings you performed to finish the challenge and so take a screen shooting of the DNS Manager console. demoing the elements you created during the challenge. by pressing Alt+Prt Scr. and so glue the resulting image into the Lab 12 worksheet file in the page provided by pressing Ctrl+V. End of lab. You can log off or get down a different lab. If you want to re-start this lab. you’ll need to snap the End Lab button in order for the lab to be reset.
