Question 2: What is one reason why you might want to install the GRUB boot loader instead

of LILO?

Correct Answer: You want to boot from a network 

Your Answer: You want to create a system that can boot both Windows and Linux

LILO supports a wide variety of boot configurations, but you'll need the more modern GRUB

if you want to boot from a network.

Question 3: Which of the following software packages will not help you to run Windows

software on a Linux system?

Correct Answer: Samba

Your Answer: SambaWhile Samba emulates Microsoft's SMB networking protocol, it only lets Linux systems

connect to Windows servers. It won't actually help you run Windows software.

Question 4: What is a "shebang"?

Question 5: Which of the following Linux distributions is least  like the others?

Question 6: Which of the following versions of the Linux kernel is likely to be the most

stable on supported hardware?

Correct Answer: 2.4

Your Answer: 2.3

In the past, odd-numbered kernels were development releases and were therefore considered

unstable; kernel Version 2.7 doesn't even exist yet. Version 2.4 is the only stable production

release on the list.

Question 7: What distinguishes the Gentoo Linux installation procedure from that of most

other distributions?Correct Answer: It builds most of the system from source code.

Your Answer: It detects most mainstream PC hardware automatically.

A comprehensive Gentoo system can take a long time to install because it builds custom

versions of the software from your own specifications.

Question 8: Which of the following companies has not released open source Linux drivers for

its graphics hardware?

Question 10: Which of the following source code version control systems will you need to

use if you want to contribute code to the Linux kernel?

Correct Answer: GitYour Answer: CVS

Linus Torvalds created git for Linux kernel development after key contributors objected to

BitKeeper's license terms.

Question 11: The current Linux kernel source tree includes approximately how many lines of 

C++ code?

Correct Answer: Fewer than 500,000

Your Answer: Approximately 1 million

Besides the fact that Linux was started before good free C++ compilers were available, Linus

Torvalds is no fan of C++. Standard C and assembly language make up 99.71 percent of the

kernel.

Question 12: Who among the following has never contributed any source code to the Linuxkernel?

Correct Answer: Richard M. Stallman

Your Answer: Hans Reiser

Stallman thinks the name should be GNU/Linux, because the kernel doesn't function as an

OS without supporting code developed by the Free Software Foundation. But Stallman has

never actually written code for the kernel itself.

Question 13: If you needed to work primarily with very large multimedia files, which of the

following file systems would offer the best performance?

Correct Answer: XFS

Your Answer: Ext2fs

Originally developed by Silicon Graphics, XFS offers smooth data transfer and handles large

files very efficiently, either of which would be a boon to multimedia production.

Question 14: Of the following, which is the most widely used GUI windowing system among

major enterprise Linux distributions?

Correct Answer: X.org

Your Answer: Gnome

Trick question! Of the software projects listed, only X.org is a windowing system. The others

Question 15: What is the main benefit of the noatime mount option for Linux file systems?

Correct Answer: It improves performance by reducing the frequency of disk writes

Your Answer: It improves performance by reducing the frequency of disk writesNormally, Linux will update the time stamp on a file every time it is accessed. With the

noatime option, the kernel will update files only when their contents are changed.

Question 16: Which of the following virtualization technologies allows Windows virtual

machines to run on a Linux system?

Correct Answer: Xen

Most of the virtualization software listed can only launch other instances of Linux. Xen can

support Windows virtual machines also, provided your processor supports Intel VT or AMD-

V technology.

Question 17: In Linux parlance, what is a "binary blob"?
