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 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

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.

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.

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?

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.

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.
