You have a server named DNS1 that runs Windows Server 2012 R2.
You discover that the DNS resolution is slow when users try to access the company intranet home page by
using the URL http://companyhome.
You need to provide single-label name resolution for CompanyHome that is not dependent on the suffix search
order.
Which three cmdlets should you run? (Each correct answer presents part of the solution. Choose three.)

A.
Add-DnsServerPrimaryZone

B.
Add-DnsServerResourceRecordCName

C.
Set-DnsServerDsSetting

D.
Set-DnsServerGlobalNameZone

E.
Set-DnsServerEDns

F.
Add-DnsServerDirectory Partition

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.
