You need to ensure that the zone only replicates to DNS servers that support DNSSEC

Your network contains an Active Directory forest named contoso.com. Contoso.com contains three domain controllers that run Windows Server 2008 R2 and three domain controllers that run Windows Server 2003. All domain controllers are configured as DNS servers. You configure the contoso.com zone to use DNSSEC. You need to ensure that the zone only replicates to DNS servers that support DNSSEC. What should you do first?

A.
Modify the Notify settings of the contoso.com zone.

B.
Create an application directory partition.

C.
Move the contoso.com zone to the ForestDnsZones application directory partition.

D.
Add a server certificate to the Windows Server 2003 DNS servers.

Explanation:
you’ve installed Windows Server 2008 Core, you don’t use DHCP and you want to get the thing So

on the network. I keep forgetting how to do this so I thought remember!
I’m assuming that you’ve got as far as changing the administrator password and logging in. The next step is as easy as typing a few commands into the plain black window you see in front of you. let’s assume that we want the server to have the following network configuration:
For this example,

HOSTNAME: win2008core
IP ADDRESS: 10.1.5.16
SUBNET MASK: 255.255.255.128
DEFAULT GATEWAY: 10.1.5.126

DNS SERVER: 10.10.20.6
DNS SERVER: 10.20.4.3

We first have to extract two pieces of information from the server. The current hostname and the index of the NIC that we want to configure.
The hostname can be acquired simply by entering the command:
“WIN-87abac8chasa87 or something random like that.
hostname This will return something like
we’ll need it later.
Make a note of the name returned as

Next enter the following command:
netsh interface ipv4 show interfaces
This will return an output a bit like the one below. The important thing though is getting the index you’re interested in (3 in this case). By default this will probably be (Idx) value for the interface that
“Local Area Connection”.
called
To setup the IP details for the interface just enter the following command:
netsh interface ipv4 set address name=”3″ source=static address=10.1.5.16 mask=255.255.255.128
gateway=10.1.5.126
To add the DNS servers to this interface, use the following commands:
netsh interface ipv4 add dnsserver name=”3″ address=10.10.20.6 index=1 netsh interface ipv4 add dnsserver name=”3″ address=10.20.4.3 index=2 Note that we incremented the index value in the second command. That was quite easy really. All that remains is to rename the server. This is done with another simple command using the value that we obtained earlier:
netdom renamecomputer WIN-87abac8chasa87 /NewName:win2008core All that you then need to do is reboot the server:
shutdown /r /t 0
