QUESTION NO: 251
You are the administrator of TestKing’s network. The network includes one DNS server running UNIX,
three file servers running NetWare 5.0, two servers running Windows 2000 Server, and 250 client
computers. The client computers run either Windows 2000 Professional or Windows NT Workstation 4.0.
Currently, all computers on your network use TCP/IP as their only network protocol, and all have static
IP addresses. All client computers have the address of the DNS server statically entered.
You install DHCP and DNS on a new computer named DD1, which runs Windows 2000 Server. You then
decommission the UNIX DNS server. You configure DD1 to require secure dynamic updates. You also
configure DD1 so it always DNS records for all DHCP clients. You configure the DHCP scope to assign
DD1 as the DNS server for all client computers. All servers continue to use static IP addresses.
Users now report they cannot access resources located on the NetWare file servers. However, they can
access resources located on the Windows 2000 computers.

You need to ensure that all users can access resources on the NetWare file servers. What should you do?
A. Configure DD1 so it does not require secure dynamic updates.
B. Configure the NetWare file servers to point to DD1 for DNS name resolution.
C. On DD1, create CNAME (canonical name) records that point to the NetWare file servers.
D. On DD1, create A (host) records that point to the NetWare file servers.

Answer: D

Explanation: We must manually add A (Host) records for the NetWare file servers. NetWare computers would
not be able to use dynamic DNS and register themselves in the DNS zone.
Incorrect Answers:
A: The NetWare file servers would not be able to register themselves dynamically under any
circumstances. Removing the requirement for secure dynamic updates would not enable the NetWare
file servers to register in the DNS zone.
B: The Windows 2000 clients must be able to access the NetWare file servers. We don't have to change
how the NetWare file servers uses name resolution.
C: Canonical name (CNAME) records enable you to associate more than one host name with an IP address.
This is sometimes referred to as aliasing. In this scenario, however, we don't have any records for the
NetWare file servers in the DNS zone so adding CNAME records for them would be pointless.
