Overview

Introduction

The Installing and Configuring DHCP Server Part 2 module provides you with the instruction and server hardware to develop your hands-on skills in the defined topics. This module includes the following exercises:

  • Preparing System Requirements for a Multi-Segment Network
  • Managing DHCP Server Scopes
  • Implementing DHCP Fault Tolerance

Lab time: It will take approximately 1 hour to complete this lab.

Exam Objectives

The following exam objectives are covered in this lab:

  • Creating Superscopes and Multicast Scopes
  • Configuring a Resilient DHCP Infrastructure

Exercise 1 - Preparing System Requirements for a Multi-Segment Network

Enterprise networks spanning multiple network segments typically have DHCP servers in each network that handle the allocation of IP addresses, subnet masks, and other essential TCP/IP configurations to enable the seamless connection of Windows clients to corporate resources.

In this exercise, you will create a scenario where a DHCP server with connections to two network subnets, namely 192.168.0.0 and 192.168.1.0, will lease IP addresses to Windows clients. A virtual machine guest called PLABDC02 will be set up as a domain server and a DHCP server to complete this objective.

Exercise 2 - Managing DHCP Server Scopes

Part of creating and managing a DHCP server is the creation and management of IP address pools or Scopes. DHCP Scopes contain a database of IP addresses that are leased to requesting DHCP clients to ensure connectivity.

An enterprise network normally spans more than one network subnet and is distributed in different locations. A Superscope in DHCP is an administrative tool that allows an administrator to manage multiple IP address pools and group them into a single entity.

Exercise 3 - Implementing DHCP Fault Tolerance

A DHCP server supports the failover of IP address Scopes to another server to ensure uninterrupted access to essential client/server applications by client workstations on the corporate network.

In this exercise, you will configure failover between two servers, PLABDC01 and PLABDC02, both of which are running DHCP services. Failover is possible between DHCP servers if both are members of the same Active Directory domain.

DHCP supports the implementation of name protection where DHCP registers a computer’s hostname and IP address of a client to the preferred DNS server. This feature prevents duplicate registration of Host (A) and Pointer (PTR) records to the DNS server, by another client workstation.
