You need to keep several things in mind when designing a complex name resolution strategy at the enterprise level. These include prioritizing security while at the same time providing a reliable and robust infrastructure for the organization. Several features of Windows Server 2012 can be used to create this robust and reliable design.
In addition to the features you can use to create a robust and reliable design, you should also be intimately familiar with DNS for the exam. This includes being familiar with the DNS protocol as well as the tools and concepts surrounding implementation of DNS in an enterprise.
Many of these tools and concepts have existed for quite some time and aren’t directly called out as objectives on the exam. As an enterprise administrator, you are expected to have the prerequisite knowledge of a primary protocol such as DNS.

Note: ADDITIONAL REFERENCES
Table 2-2 provides links to additional reference information for these concepts, but you’re encouraged to pursue supplemental DNS information beyond that which is listed here and on the exam objectives.
