QUESTION 6
To set up a connection to your ISP via your modem, what should you do (choose all that apply):
A. configure the dialer
B. configure the PPP settings
C. configure the pppd daemon
D. configure the PPTP settings
Answer: A,B,C
Explanation: As described in Debian's support document, there are actually two parts to setting up a
connection to your ISP. You have to configure the dialer (the chat program), and the PPP (Point-to-Point
Protocol) settings (the pppd daemon). PPP is the protocol that modems use to communicate over a serial
link. (PPP is a powerful protocol that is also often used when connecting distant routers over dedicated
leased lines.)

QUESTION 7
The modem speed setting of _________ may be too high only if your computer doesn't have a 16550 UART
chip.
A. 115200
B. 56700
C. 38400
D. 28800
Answer: A
Explanation: As described in Debian's support document, the speed setting of 115200 may be too high
only if you have a 486 computer that doesn't have a 16550 UART chip. If you're using a 486 and not sure
of the UART, play it safe and set the speed to 56700 instead. Exit the ee editor saving the file.

QUESTION 8
You wish to configure your soundcard. Type in the name of the Red Hat text/gui application that allows
you to set/autodetect the sound card?

A. have a kernel with the OSS sound modules ready
B. have a sound card chip with the OSS sound modules ready
C. have the on board sound module disabled
D. None of the choices.
Answer: A
Explanation: Sndconfig uses isapnp to detect common soundcards and writes a isapnp configuration to
and module control lines for use with your sound card. It requires a kernel with OSS sound modules to
be present.

QUESTION 10
What is used by Sndconfig to detect common soundcards (choose all that apply):
A. isapnp
B. pcipnp
C. usbpnp
D. None of the choices.
Answer: A
Explanation: Sndconfig uses isapnp to detect common soundcards and writes a isapnp configuration to
and module control lines for use with your sound card. It requires a kernel with OSS sound modules to
be present.

QUESTION 11
What Linux utility allows you to easily configure your Sound Blaster card on Linux?
A. Sndconfig
B. SoundConf
C. Usrconf
D. Sysconf
Answer: A
Explanation: Sndconfig is a utility that lets you configure your soundcard easily. It was written originally
for RedHat Linux, but now it is available for Debian GNU/Linux, too.

QUESTION 12
Sndconfig was written originally for which Linux distribution?
A. RedHat
B. SuSE
C. Debian
D. Corel
Answer: A
Explanation: Sndconfig is a utility that lets you configure your soundcard easily. It was written originally
for RedHat Linux, but now it is available for Debian GNU/Linux, too.

QUESTION 14
You have an old computer that you have set up to connect to the Internet with an external 56K modem
but are unable to establish a connection of greater than 9600bps.

A. Winnmodems are not supported in Linux.
B. The UART is not capable of handling more than 9600bps.
C. The serial port is not recognized by the kernel.
D. The modem is not configured to use the correct IRQ.
Answer: B

QUESTION 15
The _____ daemon is needed to establish a PPP link to another computer?
Answer: pppd

QUESTION 16
Which of the following is the ppp configuration file?
A. /etc/ppp/peers/provider
B. /etc/ppp/ provider
C. /etc/peers/ppp
D. /ppp/peers/provider
Answer: A
Explanation: As described in Debian's support document, /etc/ppp/peers/provider is the ppp
configuration file. You edit it by typing in:
cd /etc/ppp/peers<
ee provider

QUESTION 17
Your system allows only two serial ports to be active. You want to setup an internal ISA modem. Currently the
serial port 1 is used by a mouse. What should you do?
A. disable the second serial port in the BIOS and set the modem up to take its place.
B. enable the second serial port in the BIOS and set the modem up without a port.
C. disable the second serial port in the BIOS and set the modem up to run as port 3.
D. None of the choices.
Answer: A
Explanation: As described in Debian's support document, newer systems will come with either one or two
serial ports which are built into the motherboard. These are typically 9-pin male connectors on the back
of the PC. You can simply connect an external modem to one of these. If you add an internal modem to
the system it has to be set up as the next serial port (for example number 3 in a system that has two of
them built in). Or, if you system BIOS allows it, you could disable the second serial port and set the
modem up to take its place.

QUESTION 18
Which of the following modems are not supported by Linux (choose all that apply):
A. winmodem
B. 28.8K modem
C. 33.6K modem
D. 56K modem
Answer: A
Explanation: As described in Debian's support document, make sure your modem is not a "winmodem"
(a stripped-down modem that's controlled through a Windows software driver). Second, if at all possible
get yourself an external modem. An external non-winmodem modem presents a lot less headaches trying
to be PCI bus modems (which present driver issues), or they have to be set up via software - software
which is usually only available for Windows.

QUESTION 19
What command should you use to find out the version of the pppd daemon you're using (fill in the blank):
Answer: pppd -v
As described in Debian's support document, knowing the version of the pppd daemon you're using can
sometimes be useful. While pppd doesn't have a command-line parameter to show the version, using the -v
parameter does work because it's seen as an invalid parameter and, as such, causes the help screen to appear.

QUESTION 20
What is the name of the point to point protocol daemon that is used when connecting with a modem?
Answer: pppd

QUESTION 21
What program is needed to establish a PPP link to another computer?
A. pppd
B. wvdial
C. papd
D. kppp
Answer: B

QUESTION 27
Which of the following opens the specified SCSI device file and retrieves its actual SCSI address parameters?
A. Scsi_info
B. Scsi_dev
C. Scsiinfo
D. Scsi_conf
Answer: A
Explanation: Scsi_info opens the specified SCSI device file, and retrieves its actual SCSI address
parameters. It also looks up the device in /proc/scsi/scsi and retrieves the device's vendor information, if
available. Its output is a pair of Bourne-style shell commands to define the SCSI_ID and MODEL
variables based on this information. The SCSI_ID variable has three comma-separated fields: the SCSI
channel number, the device ID, and the logical unit number. In most cases, the channel and logical unit
will be 0.
QUESTION 28
Scsi_info looks up the device in which file?
A. /proc/scsi/scsi
B. /proc/scsi/scsi_info
C. /proc/scsi_info/scsi
D. /scsi/scsi
Answer: A
Explanation: Scsi_info opens the specified SCSI device file, and retrieves its actual SCSI address
parameters. It also looks up the device in /proc/scsi/scsi and retrieves the device's vendor information, if
available. Its output is a pair of Bourne-style shell commands to define the SCSI_ID and MODEL

QUESTION 61
To build a fresh new Linux system, how much free space should you reserve for the Linux partition?
A. 100 - 200MB
B. 200 - 300MB
C. 300 - 400MB
D. 700 - 800MB
Answer: D
Explanation: According to the technical information available at Linux From Scratch Ver 3.0, Before we
can build our new Linux system, we need to have an empty Linux partition on which we can build our
new system. I recommend a partition size of at least 750 MB. This gives enough space to store all the
tarballs and to compile all packages without worrying about running out of the necessary temporary disk
space. But you probably want more space than that if you plan to use the LFS system as your primary
Linux system.
