Your network contains an Active Directory domain named contoso.com. The domain contains a member server
named Server1. Server1 runs Windows Server 2012 andhas the DHCP Server server role installed.
You create two IPv4 scopes on Server1. The scopes are configured as shown in the following table.
The DHCP clients in Subnet1 can connect to the client computers in Subnet2 by using an IP address or a
FQDN.
You discover that the DHCP clients in Subnet2 can connect to client computers in Subnet1 by using an IP
address only.
You need to ensure that the DHCP clients in both subnets can connect to any other DHCP client by usinga
FQDN.
What should you add?
A.
The 006 DNS Servers option to Subnet2
B.
The 015 DNS Domain Name option to Subnet1
C.
The 006 DNS Servers option to Subnet1
D.
The 015 DNS Domain Name option to Subnet2
Explanation:
To enable DNS on the network, you need to configureDNS clients and servers. When you configure DNS
clients, you tell the clients the IP addresses of DNS servers on the network. Usingthese addresses, clients can
communicate with DNS servers anywhere on the network, even if the servers areon different subnets.
When the network uses DHCP, you should configure DHCP to work with DNS. To do this,
you need to set theDHCP scope options 006 DNS Servers and 015 DNS Domain Name.
Issue: The DNS domain option (option 15) is not configured for one or more scopes. Impact: DHCP IPv4 clients
will not be provided with a DNS domain and will notbe able to resolve names.
Resolution:
Configure a DNS domain option as a server or scope option using the DHCP MMC: Dynamic Host
Configuration Protocol (DHCP) uses options to pass additional Internet Protocol (IP) settings toDHCP clients on
a network. Examples of DHCP options include: The default gateway IP address, The Domain Name System
(DNS) serverIP address
The DNS domain name
Membership in the Administrators or DHCP Administrators group is the minimum required to complete
thisprocedure.
To configure DNS server as a scope option or serveroption
1. Click Start, point to Administrative Tools and then click DHCP.
2. In the console tree, expand the App1icable DHCP server, expand IPv4, and then right- click Server Options
3. Click Configure Options, check 015 DNS Domain Name, type the App1icable domain name in String value:,
and then click OK.
