IT Ess 2 Modul 12

1 Which version of the Linux kernel includes ISA PnP support that does not require the isapnp program?

2.1.x
2.2.x
2.3.x
*2.4.x

2 Which program is used to insert a single module into the Linux kernel?

imsmod
smod
ismod
*insmod

3 A module needs to be loaded. However, confirmation that the Linux kernel can load the module is important. Which of the following options of the insmod program will accomplish this task?

-s
*-p
-f
-k

4 Which option of the insmod program will send output to a log file instead of the console?

*-s
-p
-f
-k

5 What is the main concept to be aware of when installing hardware on a Linux system?

price
type of device
*compatibility
number of slots available

6 Which insmod option will automatically unload the module when it is no longer being used?

-s
-p
-f
*-k

7 Which Linux file needs to be edited to specify an IRQ for an Ethernet card?

/lilo.conf
/irq.conf
*/etc/lilo.conf
etc/loli.conf
/etc/irq.conf

8 Which of the following factors should be considered when installing a SCSI drive to ensure system compatibility? (Choose three.)

*variant
RPM
*ID
*termination
drive size
average seek time

9 What would be the most important feature to consider when selecting a video card for a workstation based on performance?

warranty
*amount of on-board RAM
manufacturer
price

10 What is the most common cause of core system hardware failure?

static discharge
*overheating
incorrect drivers
excessive use and age
physical damage

11 Which insmod option will instruct the program to load the module even if the module was compiled for a different kernel?

-s
-p
*-f
-k

12 How is PnP handled in a Linux system? (Choose two.)

*isapnp program
iopnp program
ISA configuration option in control panel
*ISA configuration option in the Linux kernel

13 On a Linux system, which of the following files will show the interrupt request number allocation?

/dev/interrupt
*/proc/interrupt
/interrupt
/var/interrupt

14 A technician is adding an internal PnP modem to a system, but a check of system resources shows that all available IRQs are reserved or being used by other devices. What could the technician do to get the device to work?

manually assign the IRQ of another device that is not expected to be used at the same time as the modem
use trial and error to find an IRQ that will work with the modem
configure the modem to work without an IRQ
change CMOS settings to allow the BIOS to free up an unused IRQ
*configure the modem to use a DMA address instead of an IRQ

15 A new EIDE hard drive has been added to a Linux workstation. The hard drive is functioning but performance is poor. What should the administrator do first to check the installation?

ensure that the ribbon cable connector being used is the one closest to the motherboard
ensure that the jumpers on the hard disk are set to configure it as the master drive on EIDE channel 1
repartition the disk to create smaller partitions
*use the hdparm utility to test the disk and set options

16 Which of the following Linux files can be viewed to see resource allocations? (Choose three.)

*/proc/interrupt
*/proc/dma
/proc/imports
*/proc/ioports
/proc/alloc

17 Which two steps should a technician perform first when troubleshooting a new EIDE hard drive installation that a computer does not recognize? (Choose two.)

*check CMOS to ensure that the hard drive settings are correct
*ensure that the drive has the correct master or slave jumper settings
ensure that the kernel contains the correct drivers for the drive
make sure the device number and termination are correct

18 Which of the following is an OS-independent component that is responsible for basic hardware and resource configuration before the OS loads?

*USB ports
SCSI
BIOS
CPU

19 Some PCMCIA driver packages allow drivers to be mounted while a device is installed and unmounted when the device is removed from a laptop. Which feature makes this possible?

ACPI
*Card Services
lsmod
mount
sleep
umount

20 Which two of the following statements about SCSI devices and configuration are true? (Choose two.)

*The SCSI controller needs to be terminated if it is at the end of a chain.
A forked chain occurs when two SCSI cables are connected to a single controller.
Throughput can be reduced if all SCSI devices are not the same variant.
*All SCSI devices in a chain must have the same device number.
