CompTIA Linux+ XK0-006 (V8) Practice Question

You previously compressed a large ISO image with xz and noticed that the original file disappeared after the job finished. This time you must:

  • Achieve the highest compression ratio (maximum preset in its extreme variant).
  • Use all available CPU cores on an 8-core workstation.
  • Keep the input file so that the uncompressed ISO remains on disk.

Which command line meets all three requirements when run from the directory that contains the file image.iso?

  • xz -9e -d -T0 -k image.iso

  • xz -9e -T0 -k image.iso

  • xz -9e -T0 image.iso

  • xz --keep -T all -9e image.iso
