What should you configure?

Your network contains an Active Directory domain named contoso.com. The domain
contains a domain controller named DC1. DC1 is a DNS server for contoso.com. The
properties of the contoso.com zone are configured as shown in the exhibit. (Click the Exhibit button.)

The domain contains a server named Server1 that is part of a workgroup named Workgroup.
Server1 is configured to use DC1 as a DNS server.
You need to ensure that Server1 dynamically registers a host (A) record in the contoso.com
zone.
What should you configure?

A.
The workgroup name of Server1

B.
The Security settings of the contoso.com zone

C.
The Dynamic updates setting of the contoso.com zone

D.
The primary DNS suffix of Server1

Explanation:
When any computer or a standalone server is added to a domain as a member, the network
identifies that computer with its Fully Qualified Domain Name or FQDN. A Fully Qualified
Domain Name consist of a hostname and the DNs suffix separated by a “. ” called period. An
example for this can be server01. msftdomain.com where “server01″ is the hostname of the

computer and “msftdomain.com” is the DNS suffix which follows the hostname. A complete
FQDN of a client computer or a member server uniquely identifies that computer in the entire
domain.
Primary DNS suffix must manually be added in Windows 8 computer to change its hostname
to Fully Qualified Domain Name so that it becomes eligible to send queries and receive
responses from the DNS server. Following are the steps which can be implemented to add
primary DNS suffix to a Windows 8 computer hostname:
Log on to Windows 8 computer with administrator account.
From the options available on the screen click Control Panel.
On the opened window click More Settings from the left pane.
On the next window click System and Security category and on the appeared window click
System.
On View basic information about your computer window click Change settings under
Computer name, domain, and workgroup settings section.
On System Properties box make sure that Computer Name tab is selected and click
Change button.
On Computer Name/Domain Changes box click More button.
On DNS Suffix and NetBIOS Computer Name box type in the DNS domain name as the
DNS suffix to the Windows 8 computer under Primary DNS suffix of this computer field.
Click Ok button on all the boxes and restart the computer to allow changes to take effect.

For years, Windows DNS has supported dynamic updates, whereas a DNS client host
registers and dynamically updates the resource records with a DNS server. If a host’s IP
address changes, the resource record (particularly the A record) for the host is automatically
updated, while the host utilizes the DHCP server to dynamically update its Pointer (PTR)
resource record. Therefore, when a user or service needs to contact a client PC, it can look
up the IP address of the host. With larger organizations, this becomes an essential feature,
especially for clients that frequently move or change locations and use DHCP to
automatically obtain an IP address. For dynamic DNS updates to succeed, the zone must be
configured to accept dynamic updates:
