[单选题]Ezonexam.com's network contains two domain controllers and approximately 500 client computers. The domain controllers run Windows 2000 Server. The client computers run Windows 2000 Professional. The majority of users have mobile computers. Users in Ezonexam often travel with their mobile computer for extended periods of time and do not have remote access to Ezonexam.com's network.You want to configure the domain controllers so that DNS only contains entries for computers that are active on the network. You also want to ensure that when users return you do not have to manually create or delete DNS entries.

正确答案 ：D

Configure both domain controllers with Active Directory integrated primary zones for the domain and enable scavenging and dynamic updates for the zone.

解析：解析：Explanation: Scavenging is a process whereby a DNS server periodically checks it's dynamically created records to see how long it's been since they were registered (or reregistered). Then, if the scavenger finds records that haven't been registered or reregistered in a long time, it deletes them from the zone file.
