5. Which of the following is not an advantage of SCSI hard disks over EIDE hard disks?

A. SCSI supports more devices per IRQ.

B. SCSI hard disks are less expensive than their EIDE counterparts.

C. SCSI allows multiple simultaneous transfers on a single chain.

D. The highest-performance drives come in SCSI format.

6. As a general rule, which of the following is most important in order for a video card to be used in a Linux business workstation?

A. The card should be supported by the commercial Accelerated-X and Metro-X servers.

B. The card should have much more than 8MB of RAM for best speed.

C. The card should be supported by XFree86.

D. The card should be the most recent design to assure continued usefulness in the future.

7. When installing an EIDE hard disk, what feature might you have to set by changing a jumper setting on the disk?

B. The drive's termination (on or off)

C. The drive's master or slave status

8. Why might you want to check the motherboard BIOS settings on a computer before installing Linux?

A. The BIOS lets you configure the partition to be booted by default.

B. You can use the BIOS to disable built-in hardware you plan not to use in Linux.

C. The motherboard BIOS lets you set the IDs of SCSI devices.

D. You can set the screen resolution using the motherboard BIOS.

9. You want to attach an old 10MBps SCSI-2 scanner to a computer, but the only SCSI host adapter you have available is a 20MBps UltraSCSI device. The system has no other SCSI devices. Which of the following is true?

A. You can attach the scanner to the UltraSCSI host adapter; the two are compatible, although you may need an adapter cable.

B. You must set an appropriate jumper on the UltraSCSI host adapter before it will communicate with the SCSI-2 scanner.

C. You must buy a new SCSI-2 host adapter; SCSI devices aren't compatible across versions, so the UltraSCSI adapter won't work.

D. You can attach the scanner to the UltraSCSI host adapter, but performance will be very poor because of the incompatible protocols.

10. A new Linux administrator plans to create a system with separate /home, /usr/local, and /etc partitions. Which of the following best describes this configuration?

A. The system won't boot because /etc contains configuration files necessary to mount non-root partitions.

B. The system will boot, but /usr/local won't be available because mounted partitions must be mounted directly off of their parent partition, not in a subdirectory.

C. The system will boot only if the /home partition is on a separate physical disk from the /usr/local partition.

D. The system will boot and operate correctly, provided each partition is large enough for its intended use.

11. Which of the following best summarizes the differences between DOS's FDISK and Linux's fdisk?

A. Linux's fdisk is a simple clone of DOS's FDISK, but written to work from Linux rather than from DOS or Windows.

B. The two are completely independent programs that accomplish similar goals, although Linux's fdisk is more flexible.

C. DOS's FDISK uses GUI controls, whereas Linux's fdisk uses a command-line interface, but they have similar functionality.

D. Despite their similar names, they're completely different tools— DOS's FDISK handles disk partitioning, whereas Linux's fdisk formats floppy disks.

12. Which of the following characteristics differ between Linux and commercial Unix systems? (Choose all that apply.)

A. Ability to run open source software

B. Cost

C. History of kernel source code base

D. Underlying principles of OS design

13. In what ways do Linux distributions differ from one another? (Choose all that apply.)

B. Kernel development history

C. Installation routines

D. Ability to run popular Unix servers

14. Which of the following packages are most likely to be needed on a computer that functions as an office file server?

B. Unused firewall software

C. Uncompiled source code

D. Software development tools

16. Which of the following is not required in order for software to be certified as open source?

B. The license must not require that the software be distributed as part of a specific product.

C. The license must not require that changes be distributed under the same license.

D. The program must come with source code, or the author must make it readily available on the Internet.

17. Which of the following is true of commercial software licenses in

Linux? (Choose all that apply.)

C. They are uncommon compared to open source licenses.

D. They necessarily prevent distribution of the commercial package with a Linux distribution.

18. How do you set IRQs on PCI boards?

A. You don't; PCI boards don't use IRQs.

B. You don't; they're set automatically by the BIOS or kernel.

C. By adjusting jumpers on the board.

D. By editing the /etc/isapnp.conf file and running isapnp.
