XK0-005 Question #1831: Real Exam Question with Answer & Explanation

Question

An administrator wants to copy files from /opt/tools to the home directory at /home/admin. Which of the following should the administrator run?

Options

• Amkdir -p /home/admin/tools
• Bcp -R /opt/tools ~
• Ccd /opt/tools; rsync /home/admin
• Dscp /opt/tools localhost:/

Explanation

To copy the /opt/tools directory and its contents to the /home/admin directory, the cp -R command with the tilde shorthand for the home directory is the correct approach.

Common mistakes.

• A. mkdir -p only creates a directory if it does not already exist; it does not copy any files or directories.
• C. rsync requires both a source and a destination, and the provided syntax is incomplete and incorrect for the stated goal of copying, as cd only changes the current directory.
• D. scp is used for secure copying, but localhost:/ specifies the root directory on the local host, not the home directory, and this syntax is not the most direct way to copy a directory to a user's home folder.
