Question 1

In Linux the semaphore structure contains ____ fields.
A) two
B) three
C) four
D) five

Accepted Answer

The semaphore structure in Linux contains three fields: a value, a wait queue, and a spinlock. The value field holds the current value of the semaphore, the wait queue holds the processes currently waiting on the semaphore, and the spinlock is used to protect access to the semaphore.

Question 2

Linux terminal management conforms to ____ standards, and it also supports pseudo-terminals as well as process control systems.
A) POSIX
B) SCSI
C) USB
D) DLL

Accepted Answer

Linux terminal management conforms to POSIX standards, which is a set of standards that specify the behavior of operating systems and their interfaces, particularly those that are designed to be compatible with UNIX. It also supports pseudo-terminals, which are virtual terminals controlled by the user program, and process control systems, which allow the user to manage multiple processes concurrently. SCSI and USB are hardware interfaces, and DLL is a Windows dynamic link library, none of which are relevant to Linux terminal management.

Question 3

Because Linux is written and distributed under the ____ General Public License, its source code is freely distributed and available to the general public.
A) GPL
B) Open Publication
C) GNU
D) MPP

Accepted Answer

Linux is distributed under the GNU General Public License, which allows the source code to be freely distributed and available to the general public.

Question 4

Virtual memory in Linux is managed using a multiple-level table hierarchy, which accommodates both 64- and ____-bit architectures.
A) 32
B) 96
C) 128
D) 512

Accepted Answer

The multiple-level table hierarchy in Linux virtual memory management accommodates both 64- and 32-bit architectures. Therefore, option A is the correct choice. Options B, C, and D are not valid choices as they do not align with the available options for architectures in Linux virtual memory management.

Question 5

Linux provides ____ queues and semaphores to allow two processes to synchronize with each other.
A) exec
B) fork
C) wait
D) pause

Accepted Answer

Linux uses the wait system call to allow one process to wait for another to finish, which is a form of synchronization. Queues and semaphores are also synchronization mechanisms but are not explicitly listed in the options.

Question 6

The page replacement algorithm is an expanded version of the ____ replacement policy.
A) clock page
B) clock
C) page clock
D) page

Accepted Answer

The answer of The page replacement algorithm is an expanded...

Question 7

Fedora Core 2 was introduced in ____.
A) 2003
B) 2004
C) 2005
D) 2006

Accepted Answer

Fedora Core 2 was released in May 2004.

Question 8

Linux is ____, which improves its portability from one system to another.
A) device unique
B) device portability
C) device dependent
D) device independent

Accepted Answer

Linux is device independent, meaning it is not tied to any specific hardware or architecture. This allows it to be easily ported from one system to another without requiring significant changes to the underlying code.

Question 9

Filenames are not case sensitive in Linux.

Accepted Answer

In Linux, filenames are case sensitive, meaning that "File.txt" and "file.txt" would be considered two distinct files.

Question 10

A path name can be either one name or a list of names separated by dashes.

Accepted Answer

A path name can be either one name or a list of names separated by forward slashes (/) or backslashes (\) depending on the operating system. Dashes are not used to separate names in a path.

Question 11

The Fedora Project issues updates free to the public about every ____ months.
A) two
B) four
C) six
D) eight

Accepted Answer

Fedora Project releases updates approximately every six months.

Question 12

All Linux files are organized in directories that are connected to each other in a treelike structure.

Accepted Answer

This is true, Linux follows a hierarchical file system where directories are organized in a tree-like structure. The root directory is the starting point of the tree, and all other directories branch out from it.

Question 13

Only when all FIFO processes are completed does the scheduler proceed to execute processes of ____ priority.
A) higher
B) lower
C) the highest
D) the lowest

Accepted Answer

In a FIFO (First In, First Out) scheduling, processes are executed in the order they arrive. Once all FIFO processes are completed, the scheduler moves on to execute processes of lower priority, as higher priority processes would have been executed first.

Question 14

Virtual memory management uses ____ levels of tables.
A) two
B) three
C) four
D) five

Accepted Answer

Virtual memory management uses three levels of tables. The first level is the page table, the second level is the page directory, and the third level is the page directory pointer table.

Question 15

In Linux device management, the ____ device number is used as an index to the array to access the appropriate code for a specific device driver.
A) major
B) minor
C) unique
D) support

Accepted Answer

In Linux device management, the major device number is used as an index to the array to access the appropriate code for a specific device driver. The minor device number is used to differentiate between different devices of the same type. Therefore, the major device number is the best answer for this question.

Question 16

When a process begins execution, its segments have a ____ size.
A) large
B) variable
C) small
D) fixed

Accepted Answer

When a process begins execution, its segments have a fixed size. This is because the operating system assigns a fixed amount of memory to the process during its creation. The size of the segments can vary depending on the specific operating system and the type of segments (code, data, stack, heap) that the process requires.

Question 17

The ____ device used in Linux memory management can be a partition on the disk or it can be a normal file.
A) pointer
B) swap
C) page
D) database

Accepted Answer

The swap device is used in Linux memory management and it can either be a partition on the disk or a normal file. A pointer is not a device used in memory management, a page refers to a unit of data that can be moved in and out of memory, and a database is not directly related to memory management.

Question 18

Information about the well-being of a Linux system is available using the System Monitor window.

Accepted Answer

The System Monitor window provides information about various factors like CPU usage, memory usage, disk usage, network activity, and more, which can help to determine the well-being of a Linux system.

Question 19

Filenames can include a space, however this can cause complications if you're running programs from the command line because a program named interview notes would be viewed as a command to run two files: interview and notes.

Accepted Answer

This is because spaces are used as delimiters in command line arguments, so the space in the filename would be interpreted as a separator between two arguments or files.

Question 20

The process of grouping and splitting usable memory is known as the ____.
A) process algorithm
B) grouping algorithm
C) buddy algorithm
D) group/split algorithm

Accepted Answer

The process of grouping and splitting usable memory is known as the buddy algorithm. This algorithm is commonly used in operating systems for memory management. It works by dividing memory into smaller chunks and then grouping them together into larger blocks as necessary. When a process requests memory, the algorithm finds the closest larger block and splits it into smaller chunks to allocate to the process. When the process releases the memory, the algorithm re-groups the smaller chunks back into larger blocks.
