Explanation:
You can use this task to create a GlobalNames zone to maintain a set of single-label, Domain Name
System (DNS) names that Windows Server 2008 DNS servers can resolve on behalf of DNS clients
throughout a single forest in Active Directory Domain Services (AD DS).
Deploying a GlobalNames zone in a single forest requires that you perform the following steps:
(A) Create a zone named GlobalNames that replicates to all domain controllers in the forest.
(B) Add an alias (CNAME) record to the zone for each host for which you want to provide single-label
name resolution. For example, if you want DNS clients to be able to access a server whose fully
qualified domain name (FQDN) is cweb.itgroup.contoso.com, add an alias (CNAME) resource record
that maps the name cweb to cweb.igroup.contoso.com.
Note:
A)
The Add-DnsServerPrimaryZone cmdlet adds a specified primary zone on a Domain Name System
(DNS) server.
B)
The Add-DnsServerResourceRecordCName cmdlet adds a canonical name (CNAME) resource
record to a specified Domain Name System (DNS) zone. A CNAME record allows you to use more
than one resource record to refer to a single host
D)

The Set-DnsServerGlobalNameZone cmdlet enables or disables single-label Domain Name System
(DNS) queries. It also changes configuration settings for a GlobalNames zone.
The GlobalNames zone supports short, easy-to-use names instead of fully qualified domain names
(FQDNs) without using Windows Internet Name Service (WINS) technology. For instance, DNS can
query SarahJonesDesktop instead of SarahJonesDesktop.contoso.com.
