Question no: 136
You are The Administrator of Testking's Network. All Client Computers Run Windows 2000 Professional.
All Servers Run Either Windows 2000 Server, Windows NT Server 4.0, or UNIX. All DNS Servers Run Versions of Bind Prior To 4.9.4.
You are planning a migration to an Active Directory domain structure. You install the DNS server service on several Windows 2000 member servers, choosing all default settings. Now you need to migrate your existing DNS records to the new DNS servers, while maintaining your existing DNS Servers As Secondary DNS Servers. Your Solution Must Involve The Fewest Possible Changes To your Current Network Configuration.
Which THREE ACTIONSHOULD You Perform? (Each Correct Answer Presents Part of The Solution. Choose Three)
A. Upgrade All Bind Versions TO 8.2.2
B. Disable Fast Zone Transfers
C. COPY AND RENAME All Zone Files from the Unix DNS Servers To The SystemRoot / System32 / DNS Folder on The New DNS Servers
D. INITIATE A zone Transfer from The New DNS Servers To The Unix DNS Servers
E. Configure the New DNS Servers with primary DNS Zones. Configure The Unix DNS Servers as Secondary Zone Servers.
F. Configure the New DNS Servers with Active Directory Integrated Zones. Configure The Unix DNS Servers as Secondary Zone Servers.
Answer: B, D, E
Explanation: by Default, All Windows-based DNS Servers USE A Fast Zone Transfer Format, Which Uses Compression and CAN include Multiple Records Per TCP Message During a connection
This Format is Also Compatible with More Recent Berkeley Internet Name Domain (Bind -Based DNS Servers That Run Versions 4.9.4 and later.
THE DNS MIGRATION Process in this Scenario Can Be Acc.complased in Three Steps.
First disable fast zone transfers on the Windows 2000 DNS servers. The reason for this is that DNS BIND 4.9.4 or later is required to support the fast zone transfer feature of Windows 2000 DNS. The fast zone transfer option is enabled by default in Windows 2000 DNS. (LEM: FAST ZONE INLY IN 2000 Native Mode.)
THEN INITIATE A zone Transfer from The New DNS Servers to the UNIX DNS Servers.
And configure the new DNS servers with primary DNS zones. Configure the UNIX DNS servers as secondary zone servers. To migrate from BIND servers using zone transfer we must install a DNS server on a Windows 2000 server computer. At the new server use the DNS console To Add Secondary Zones for All of Our EXISTING ZONES HOSTED AT THE BIND-BASED DNS Servers and
CONFIGURE The Bind Servers As The master Zones for Each of The Secondary Zones for Each of The Secondary Zones for Each of To Create. We must the initiate zone trans Servers to transfer the zones from the bind servers.
After completing the zone transfers, we must convert any of the secondary zones to primary zones that were obtained from primary zones at the BIND servers and for the other secondary zones that remain, we must update the master servers for those zones to use the new primary Servers Running Windows 2000 Server.
C Items are also possible, but more management time
