Question #2
Which numeric mode gives the owner of filea.txt read and write access and gives the group and all other users no access?
Correct answer: C
Explanation
Read is 4 and write is 2, so the owner needs 6, and group and others get 0. The mode 640 would still let the group read the file, and 400 would take away the owner's write access.

Question #7
In case the command tar -tzf backup.tar.gz leads to the following output: dira/ dira/filea.txt dira/fileb.txt Which command extracts only the file filea.txt from the archive into the current directory?
Correct answer: E
Explanation
Members to extract are named after the archive and must match the stored path, here dira/filea.txt. Using only filea.txt does not match any member, -c would create a new archive, -j expects bzip2 instead of gzip, and swapping the arguments makes tar treat dira/filea.txt as the archive.
