XK0-005 Question #1852: Real Exam Question with Answer & Explanation

Question

A systems administrator needs to compress log files using the .tar.bz2 format. Which of the following commands should the administrator use?

Options

• Atar -cvtf logs.car.bz2 /var/log/*
• Btar -cvzf logs.tar.bz2 /var/log/*
• Ctar -cvjf logs.tar.bz2 /var/log/*
• Dtar -cvbf logs.tar.bz2 /var/log/*

Explanation

To create a tar archive and compress it using bzip2, the tar command with the -c, -v, -j, and -f options is the correct approach.

Common mistakes.

• A. The -t option is used to list the contents of an archive, not to create or compress it, and -car is not a valid option for bzip2 compression.
• B. The -z option is used for gzip compression, not bzip2 compression, so it would create a .tar.gz file.
• D. The -b option sets the blocking factor of the archive, which is an advanced option and not used for selecting a compression algorithm like bzip2.
