4. C. Since the configuration looks correct, you probably didn’t screw up the copy job. However, when you
perform a copy from a network host to a router, the interfaces are automatically shut down and need to be
manually enabled with the
no shutdown
command.
5. D. Specifying the address of the DHCP server allows the router to relay broadcast traffic destined for a
DHCP server to that server.
6. C. Before you start to configure the router, you should erase the NVRAM with the
erase startup-
config
command and then reload the router using the
reload
command.
7. C. This command can be run on both routers and switches and it displays detailed information about each
device connected to the device you’re running the command on, including the IP address.
8. C. The Port ID column describes the interfaces on the remote device end of the connection.
9. B. Syslog levels range from 0–7, and level 7 (known as Debugging or local7) is the default if you were to
use the
logging ip_address
command from global config.
10. C. If you save a configuration and reload the router and it comes up either in setup mode or as a blank
configuration, chances are the configuration register setting is incorrect.
11. D. To keep open one or more Telnet sessions, use the Ctrl+Shift+6 and then X keystroke combination.
12. B, D. The best answers, the ones you need to remember, are that either an access control list is filtering
the Telnet session or the VTY password is not set on the remote device.
13. A, D. The
show hosts
command provides information on temporary DNS entries and permanent name-to-
address mappings creat ed using the
ip host
command.
14. A, B, D. The
tracert
command is a Windows command and will not work on a router or switch! IOS uses
the
traceroute
command.
15. D. By default, Cisco IOS devices use facility local7. Moreover, most Cisco devices provide options to change
the facility level from their default value.
16. C. To see console messages through your Telnet session, you must enter the
terminal monitor
command.
17. C, D, F. There are significantly more syslog messages available within IOS as compared to SNMP Trap
messages. System logging is a method of collecting messages from devices to a server running a syslog
daemon. Logging to a central syslog server helps in aggregation of logs and alerts.
18. E. Although option A is certainly the “best” answer, unfortunately option E will work just fine and your boss
would probably prefer you to use th e
show cdp neighbors detail
command.
19. D. To enable a device to be an NTP client, use the
ntp server
IP_address version number
command at global configuration mode. That’s all there is to it! Assuming your NTP server is working of
course.
20. B, D, F. If you specify a level with the “logging trap
level” command, that level and all the higher levels will
be logged. For example, by using the
logging trap 3
command, emergencies, alerts, critical, and error
messages will be logged. Only three of these were listed as possible options.
