Chapter 9 Practice Test Answers
1. A. Simple Network Management Protocol (SNMP) allows the administrator to
monitor the network from a network management system (NMS).
2. B. Windows Internet Name Service allows NetBIOS names to be resolved to IP
addresses.
3. B. An A record lists a unique host name and IP address in the DNS database.
4. C. UNIX workstations can only use DNS to resolve host names to IP addresses.
5. D. BOOTP allows a diskless workstation to receive an IP address automatically.
6. B. A client node may keep an IP address for the duration of the lease time
assigned to the scope.
7. D. Reservations in DHCP allow a client node to receive the same IP address
whenever that client requests an IP address or attempts to renew a lease.
Reservations prevent the administrator or technician from having to go to every
machine and type in all the IP information.
8. C. If a client node receives a DHCPNACK to a request for renewal of the lease,
the client node will continue to try to contact the DHCP server until T2 time. At
T2 time the client node will repeat the DORA process.
9. A. BOOTP allows the broadcast packets of the DHCP request process to be
repackaged and transported across the router.
10. B and C. DNS and hosts file will both allow the client to resolve host names to IP
addresses.
11. C. It is WINS’ job to resolve a NetBIOS name to its IP address.
12. D. The fully qualified domain name (FQDN) includes the machine host name and
all domains that may represent the location of the machine in the DNS hierarchy.
13. C. SNMP agents will not report to or take orders from an NMS that is not part of
its community.
14. A. A records are unique records.
15. B. All a client node needs to register its NetBIOS name and IP address with the
WINS server is the IP address of one or more WINS servers.
16. D. The SOA record indicates which DNS server is authoritative for the zone.
17. C. NAT provides a low-level firewall that permits the use of private addresses on
the internal network while still giving users access to the Internet.
18. C, E, and H. An SNMP-managed network must have agents running on the
devices, objects to monitor, and a management console that can collect the data
provided by the agents.
19. B. NAT will not prevent unsolicited traffic from coming onto the network. What
it does do is allow the administrator to either route that traffic to a specific
resource (Web server for example) or discard the traffic.
20. B and C. This network is a mix of Windows workstations and servers and UNIX
workstations. The older Windows workstations will only use WINS for resource location,
and the UNIX boxes can only use DNS for resource location. Later Windows
workstations (2000 Professional) will use DNS first and WINS second.
