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 areconfigured 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 thatcomputer 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:
