You work as the network administrator at Domain.com. The Domain.com network consists of a single Active Directory forest containing a single domain named Domain.com. Domain.com has its headquarters located in London and branch office located in Paris. All servers on the Domain.com network run Windows Server 2008 and all client computers run Windows Vista.
Domain.com currently makes use of a computer named CERTKILLER-SR01 in the London office which has the DNS Server role installed. During the course of the day you receive instruction from Domain.com to prepare the network for decommissioning the WINS service from the network. Domain.com wants you to have forest-wide single name resolution.
What should you do?
A.
You should consider having a LegacyWINS zone created.
B.
You should consider having a GlobalNames zone created.
C.
You should consider having WINS-R lookup enabled in DNS.
D.
You should consider having Service Locator (SRV) records created for single name resources.
Explanation:
You should then have host (A) records created for single name resources.
You should then have host (A) records created for single name resources.
In order to decommission the WINS service and to enable forest-wide single name resolution, you need to create an Active Directory-integrated zone named GlobalNames and create host (A) records for the single name resources.
GNZ is intended to aid the retirement of WINS. Windows Server 2008 (WS2K8) introduces the GlobalNames zone (GNZ) where larger environments with multiple DNS suffixes can use a single name host across all domains.
To help customers migrate to DNS for all name resolution, the DNS Server role in Windows Server 2008 supports a special GlobalNames Zone (also known as GNZ) feature. Some customers in particular require the ability to have the static, global records with single-label names that WINS currently provides. These single-label names typically refer to records for important, well-known and widely-used servers for the company, servers that are already assigned static IP addresses and are currently managed by IT-administrators using WINS. GNZ is designed to enable the resolution of these single-label, static, global names for servers using DNS.
