LAB : CONFIGURING DNS ZONES

Exercise 8.1 Installing DNS

Overview

Domain Name System (DNS) is already installed on RWDC01. However, we need a second DNS server for future exercises. Therefore, during this exercise, you install a second DNS server on Server01.

Mindset

DNS is a naming service that is used by TCP/IP network and is an essential service used by the Internet. For years, Windows servers have included the DNS role.

Exercise8.2 Creating Primary and Secondary Zones

Overview

During this exercise, you create primary and secondary zones on RWDC01 and Server01.

Mindset

For the Contoso Corporation, you are building a new network. Therefore, you need to install DNS to support your network. You have three primary sites. When you use primary and secondary zones, you can have only one primary zone. The other sites have to be secondary zones. Therefore, you will have one primary zone and two secondary zones.

Exercise8.3 Creating an Active Directory Integrated Zone

Overview

During this exercise, you create an Active Directory Integrated zone.

Mindset

You decide that you want to improve the DNS system for your company and you are thinking of switching to Active Directory-Integrated zones. Active Directory-Integrated zones are fault tolerant, they offer better security, and they have more efficient replication. With these features, you don't have to worry about primary and secondary zones because each DNS server acts as a master.

Exercise8.4 Configuring Zone Delegation

Overview

In this exercise, you delegate a subdomain called support under fabrikam.com on a different DNS server.

Mindset

Subdomains allow you to break up larger domains into smaller, more manageable domains. Then by using delegation, you place the subdomain on another DNS server.

Exercise8.5 Creating a Stub Zone

Overview

In this exercise, you create a stub zone that points directly to another DNS server.

Mindset

A stub zone is a copy of a zone that contains only necessary resource records-Start of Authority (SOA), Name Server (NS), and Address/Host (A) record-in the master zone and acts as a pointer to the authoritative name server.

Exercise8.6 Configuring Forwarding and Conditional Forwarding Zones

Overview

To improve performance, you can control which DNS servers requests are forwarded to when performing naming resolution by configuring forwarding and creating conditional forwarding zones. In this exercise, you configure forwarding and create a conditional forwarding zone.

Mindset

By default, when a client contacts a DNS server and the DNS server does not know the answer, it performs an iterative query to find the answer (which means it first contacts the root domain and additional DNS servers until it finds the authoritative DNS server for the zone). However, DNS servers can be configured to be forwarded to another DNS server or a conditional forwarder based on the domain name queried.

Exercise8.7 Configuring Zone Transfers

Overview

By configuring zone transfers, you can control to which servers DNS information is copied.

Mindset

You need to configure zone transfers between multiple DNS servers. What are the three types of zone transfer available?
