Overview/Description
The DNS namespace is subdivided into different DNS zones, which are hosted by a specific authoritative server or group of servers. Zones define the DNS namespace for authoritative servers that resolve client queries. This course explores DNS zone and replication in Windows Server 2008, including stub zones and their use in Microsoft DNS. It also discusses how Primary and Secondary servers of a DNS zone must perform zone transfers to ensure each server has an up-to-date DNS database. In addition, the course describes how Active Directory-integrated DNS zones store their data in the Active Directory application partition, and rely on the AD replication process to update the appropriate servers with zone data. This course is one in a series that covers the objectives for Microsoft exam 70-642 TS: Windows Server 2008 Network Infrastructure, Configuring. Passing this exam completes the requirements for the MCTS: Windows Server 2008 Network Infrastructure, Configuring certification, and counts as credit towards the following certifications: Microsoft Certified IT Professional (MCITP): Enterprise Administrator, and the Microsoft Certified IT Professional (MCITP): Server Administrator.
