The Domain Name System (DNS) is one of the key topics that you’ll need to understand if you plan to take any of the Microsoft Windows Server 2012 R2 administration exams (70-410, 70-411, 70-412, and so forth).
It’s also imperative that you understand DNS to work with Active Directory because it requires DNS to function properly, and many important system functions (including Kerberos authentication and finding domain controllers) are handled through DNS lookups. Windows 2000, Windows XP, Windows Vista, Windows 7, and Windows 8 clients use DNS for name resolution and to find Kerberos key distribution centers (KDCs), global catalog servers, and other services that may be registered in DNS.
By the time you complete this chapter, you will have a deeper understanding of how DNS works and how to set up, configure, manage, and troubleshoot DNS in Microsoft Windows Server 2012 R2.
In this chapter, you’ll also learn how to install and manage DHCP, including how to set up plain DHCP scopes, superscopes, and multicast scopes. You’ll also learn how to set up integration between Dynamic DNS and DHCP and how to authorize a DHCP server to integrate with Active Directory.
