A)-c
B)-v

B)-e
C)-x
D)-a

Accepted Answer

The -x option is used with the tar command to extract a specified archive.

Question 4

When creating a system backup, temporary files in the /tmp and /var/tmp directories should be included.

Accepted Answer

Temporary files in the /tmp and /var/tmp directories should not be included in a system backup as they are meant to be temporary and can be recreated if necessary. Including them in a backup will only increase the backup size and time.

Question 5

It is good form to read the Makefile after you run the configure script.

Accepted Answer

Reading the Makefile after running the configure script can give you important information about the build process, including available build options and how files are compiled and linked together. This can be helpful for debugging any build issues that may arise.

The answer of When used with the compress command, the...

Question 8

You can perform up to ____ different incremental backups using the dump / restore utility.
A)7
B)8
C)9
D)10

Accepted Answer

The dump/restore utility allows for up to 9 different incremental backup levels, ranging from 0 to 9.

Question 9

The compression algorithm used by the compress utility has an average compression ratio of ____%.
A)30-40
B)40-50
C)50-60
D)60-70

Accepted Answer

The compress algorithm has an average compression ratio of 40-50%.

Question 10

The ____ option, when used with the gzip command, causes the compression ratio for files that have been compressed to be listed.
A)-c
B)-f
C)-r
D)-l

Accepted Answer

The -l option with the gzip command lists the compression ratio for files that have been compressed. Option -c is used to keep the original file, while option -f is used to force gzip to compress files, and option -r is used to compress directories recursively. None of these options give the compression ratio.

Question 11

The ____ command can be used to display the contents of a compressed file.
A)acat
B)zcat
C)cat
D)ccat

Accepted Answer

The zcat command is used to display the contents of a compressed file that has been created using gzip compression. The cat command can be used to display the contents of a normal uncompressed file. The acat and ccat commands do not exist in most Unix-based systems.

Question 12

If no level of compression is specified, the gzip command assumes the number ____.
A)4
B)5
C)6
D)7

Accepted Answer

The answer of If no level of compression is specified,...

Question 13

The make command looks for a Makefile and uses the information within to compile the source code into binary programs using the ____ for the local hardware architecture.
A)cc
B)gc
C)c++
D)gcc

Accepted Answer

The correct compiler for compiling source code into binary programs is gcc, which is a C compiler that can also compile C++ code. Choice A (cc) is a generic term for a C compiler and is not specific enough. Choice B (gc) could refer to Garbage Collection or the Go compiler, but neither are relevant to compiling source code with a Makefile. Choice C (c++) is a programming language and not a compiler, so it is not a valid choice.

Question 14

When using the compress utility, each file is renamed with a(n)____ filename extension to indicate that it is compressed.
A).c
B).cmp
C).cpz
D).Z

Accepted Answer

The Z filename extension is typically used to indicate that a file has been compressed using the compress utility.

Question 15

When using the cpio utility, the ____ option causes a new archive to be created.
A)-n
B)-c
C)-o
D)-a

Accepted Answer

The -o option in cpio utility stands for "create new archive". This option is used to create a new archive file of the specified files and directories.

Question 16

The filename extension given to files compressed with bzip2 is ____.
A).bz
B).bz2
C).gz
D).Z

Accepted Answer

Files compressed with bzip2 have a filename extension of .bz2. Option A is the filename extension for files compressed with bzip, option C is for files compressed with gzip and option D is for files compressed with compress.

Question 17

The most common package manager used by Linux systems today is the ____.
A)RPM
B)PRM
C)MPR
D)RMP

Accepted Answer

RPM (Red Hat Package Manager) is the most commonly used package manager on Linux systems, particularly on Red Hat-based distributions such as Red Hat Enterprise Linux, CentOS, and Fedora. RPM allows users to easily manage software installations, updates, and removals using a command-line interface or graphical software management tools. The other options listed (PRM, MPR, and RMP) are not valid package manager names.

Question 18

The compress utility preserves the original ownership, modification, and access time for each file that it compresses.

Accepted Answer

The compress utility does preserve the original ownership, modification, and access time for each file that it compresses.

Question 19

When using the gzip utility, the -1 option is also known as best compression and results in a higher compression ratio.

Accepted Answer

The -1 option is also known as fastest compression, which results in a lower compression ratio but quicker compression speed. The highest compression ratio can be achieved with the -9 option, also known as best compression, but it takes longer to compress.

Question 20

When used with the tar utility, the ____ option causes filenames to be stored in an archive using absolute pathnames.
A)-a
B)-b
C)-p
D)-n

Accepted Answer

The -p option, also known as --absolute-names, stores filenames using absolute pathnames. This option is used to preserve the full paths of files and directories when creating or extracting an archive.
