The correct answer is B. Configure GlobalNames zones on the DNS servers in the network. GlobalNames zones in Windows Server 2008 DNS enable single-label name resolution equivalent to WINS/NetBIOS, allowing IPv6 migration without touching client computers.
Question
You work as a Network Administrator for Infonet Inc. The company has a Windows Server 2008 Active Directory-based single forest multiple domain IPv4 network. All the DNS servers on the network run Windows Server 2008. The users in the network use NetBIOS name to connect network application on the network. Your manager requires you migrate the network to IPv6- enabled network without affecting any client computers. Which of the following actions will you take to accomplish the task?
Options
- AConfigure stub zone on the DNS servers in the network.
- BConfigure GlobalNames zones on the DNS servers in the network.
- CInstall a new Windows Server 2003 DNS server computer on each domain and configure GlobalNames
- DConfigure the client computers to use WINS.

Why each option
GlobalNames zones in Windows Server 2008 DNS enable single-label name resolution equivalent to WINS/NetBIOS, allowing IPv6 migration without touching client computers.
Stub zones only store NS and SOA records for delegated zones to improve query efficiency and do not provide any single-label name resolution capability.
GlobalNames zones let Windows Server 2008 DNS resolve single-label names (like NetBIOS names) without requiring WINS, because the zone is replicated forest-wide via Active Directory and answers single-label queries natively - clients continue using their existing NetBIOS names while the network operates over IPv6 without any client-side reconfiguration.
GlobalNames zone support was introduced in Windows Server 2008 and does not exist in Windows Server 2003, so adding a 2003 DNS server would not fulfill the requirement.
Configuring clients to use WINS directly modifies client computers, which violates the constraint of not affecting client computers and does not advance the IPv6 migration goal.
