Objective 2.8
Plan a NetBIOS Name Resolution Strategy
15-51
Objective 2.8 Answers
1.
Correct Answers: B
A. Incorrect: The NetBIOS name cache contains all the NetBIOS names that the
computer has recently resolved by any means, whether the resolved names are
for
computers on the local network or another network.
B. Correct: Broadcast transmissions are limited to the local network, so the
broad-
cast method can only resolve the name of a computer on the local network.
C. Incorrect: You can create entries in an Lmhosts file for the NetBIOS name
of any
computer on any network. In fact, the primary reason for using Lmhosts files
is to
resolve the names of computers on other networks.
D. Incorrect: WINS can resolve the NetBIOS names of any computer on any net-
work.
2.
Correct Answers: D
A. Incorrect: A computer running a Windows operating system always checks
the
NetBIOS name cache before using any other NetBIOS name resolution method,
but it uses Lmhosts only after broadcast name resolution has failed.
B. Incorrect: A computer running a Windows operating system always checks
the
NetBIOS name cache before using any other NetBIOS name resolution method,
then uses broadcasts and, failing that, Lmhosts.
C. Incorrect: Computers running Windows operating systems try to resolve
Net-
BIOS names using broadcast transmissions before they try using Lmhosts, and
they always check the NetBIOS name cache before any other mechanism.
D. Correct: A computer running a Windows operating system that is not a WINS
cli-
ent always checks the NetBIOS name cache first when trying to resolve a
NetBIOS
name, then tries the broadcast transmission method. If the broadcast method
fails,
the computer tries to look up the name in the Lmhosts file.

Correct Answers: B
A. Incorrect: This replication topology would result in only the New York
WINS
servers having complete replicas of the database, because all replication
traffic is
traveling in one direction.
B. Correct: This solution is called a ring replication topology, because
each site is
sending its data to the east and receiving data from the west. This enables
every
server to have a complete replica of the WINS database without creating a
large
amount of redundant WAN traffic.
