Your network contains a single Active Directory domainnamed contoso.com.
The domain contains two domain controllersnamed DC1and DC2that run Windows Server 2008 R2.
DC1 hosts a primary zone for contoso.com.
DC2 hosts a secondary zone for contosto.com.
On DC1, you change the zone to an Active Directory-integrated zoneand configure the zone to accept
secure dynamic updates only.
You need to ensure that DC2 can accept secure dynamic updates to the contoso.com zone.
Which command should you run?
A.
dnscmd.exe dc2.contoso.com /createdirectorypartition dns.contoso.com
B.
dnscmd.exe dc2.contoso.com /zoneresettype contoso.com /dsprimary
C.
dnslint.exe /ql
D.
repadmin.exe /syncall /force

automate routine DNS management tasks, or to perform simple unattended setup and configuration of new
DNS servers on your network.

Changes the zone type.
Syntax
dnscmd [<ServerName>] /zoneresettype <ZoneName> <ZoneType> [/overwrite_mem | /overwrite_ds]

<ServerName>
Specifies the DNS server to manage, representedby local computer syntax, IP address, FQDN, or host
name. If this parameter is omitted, the local server is used.
<ZoneName>

/dsprimary
Creates an Active Directory–integrated zone.
/primary /file <FileName>
Creates a standard primary zone.
/secondary <MasterIPAddress> [,<MasterIPAddress>…]
Creates a standard secondary zone.
/stub <MasterIPAddress>[,<MasterIPAddress>…] /file <FileName>
Creates a file-backed stub zone.
/dsstub <MasterIPAddress>[,<MasterIPAddress>…]
Creates an Active Directory–integrated stubzone.
/forwarder <MasterIPAddress[,<MasterIPAddress>]… /file<FileName>
Specifies that the created zone forwards unresolved queries to another DNS server.
/dsforwarder
Specifies that the created Active Directory–integrated zone forwards unresolved queries to another DNS
server.
/overwrite_mem | /overwrite_ds
