Exam Objectives

The following exam objectives are covered in this lab:

  • Install and configure DNS
  • Manage DNS forwarders and root hints
  • Configure DNS delegation and DNS policies

Exercise 1 - Installing and Configuring DNS Forwarders

Domain Name System or DNS is an integral part of TCP/IP networking services for any server since Windows 2000, as DNS provides name location services for all computers in a local network (like a Windows domain) and in a public network (such as the Internet).

Domain Name System consists of two components. First, the name server (DNS) hosts the resource records used for translating hostnames to numeric IP addresses or vice-versa. Second, the resolver (DNS client) runs an application that sends a request to resolve a hostname/FQDN to its numeric IP address counterpart.

A forwarder is a Domain Name System (DNS) server in a local network that is used to redirect DNS queries to an external DNS server if the names cannot be resolved within the internal network. For organizations that maintain more than one Active Directory domain, conditional forwarders can be created where a server is set up to forward queries to specific domain names, thereby making name resolution faster and more efficient.

Exercise 2 - Managing DNS Root Hints and Delegated Zones

After installing and configuring a DNS server, there are many features and options that can be enabled to realize the full capacity of DNS to resolve names beyond the internal network.

When a corporate network user connects to a resource outside of the company’s network, a DNS server uses root hints to connect to the external network and find the server.

Root hints, also known as cache hints, contain hostname information that is required to resolve names outside of the authoritative DNS domains.

In this exercise, you will examine the root hints file included with a DNS server, and configure an external DNS forwarder that will forward name resolution requests outside of the lab network.

Exercise 3 - Configuring DNS Policies

DNS Server Policies are new features that were introduced in Windows Server 2016. These policies enable administrators to control how DNS responds to DNS queries based on factors such as transport protocol, subnet (location), and time of day.
