Objective: Configuring the Domain Name System (DNS)
Sub-Objective: Configure zones


Single Answer, Multiple Choice


You are the systems administrator for Verigon Corp. The company has one main office and two branch offices named Branch1 and Branch2. Each office has its own Active Directory domain named verigon.com, branch1.verigon.com and branch2.verigon.com, respectively. The client computers in each office use the Active Directory integrated Domain Name System (DNS) for internal name resolution.


The company is closing its Branch2 office. You want to delete the DNS zone for Branch2 from the DNS server named Branch2DNS. You want to ensure that the zone is deleted from Active Directory. Which command should you run?



  1. Dnscmd Branch2DNS /zonedelete branch2.verigon.com
  2. Dnscmd /zonedelete branch2.verigon.com
  3. Dnscmd Branch2DNS /zonedelete branch2.verigon.com /dsdel
  4. Dnscmd /zonedelete branch2.verigon.com /dsdel

Answer:
C. Dnscmd Branch2DNS /zonedelete branch2.verigon.com /dsdel


Tutorial:
You should run the Dnscmd Branch2DNS /zonedelete branch2.verigon.com /dsdel command. You can use either the DNS snap-in or the Dnscmd.exe command-line utility to delete a zone. The Dnscmd utility can be used to display and change the properties of DNS servers, zones and resource records. You can use the /zonedelete parameter in the Dnscmd command to specify the name of the DNS zone that you want to delete. The /dsdel parameter can be used to delete the zone from Active Directory. The /zonedelete parameter can also be used to delete a root zone from the DNS server. Deleting the root zone is required when you want to configure DNS forwarding. A Windows Server 2008-based DNS server contains the root zone by default. Therefore, the DNS forwarding option is disabled, and the DNS server cannot act as a forwarder. To configure DNS forwarding, you should delete the root zone and enable the DNS forwarding on the DNS server. This feature forwards DNS requests to external DNS servers for name resolution.


You should not run the Dnscmd Branch2DNS /zonedelete branch2.verigon.com command. This command will only delete the branch2.verigon.com zone, but it will not ensure that the zone is deleted from Active Directory. To delete the zone from Active Directory, you should include the /dsdel parameter in your command.


You should not run the Dnscmd /zonedelete branch2.verigon.com command or the Dnscmd /zonedelete branch2.verigon.com /dsdel command. To delete a zone from a command line, you can use the Dnscmd ServerName /zonedelete ZoneName [/dsdel] [/f] command. The ServerName and ZoneName values are required in this command.
