CompTIA Linux+ XK0-005 Practice Question

A user reports that they cannot write to a file named 'report.txt' which should be writable by members of the group 'staff'. As a sysadmin, you check the permissions with ls -l report.txt and the output shows -rw-r--r-- 1 root staff 1048576 Jan 01 12:34 report.txt. What is the most likely reason for the user being unable to write to the file?

  • The file is too large to be written to by group members

  • The file only has write permissions for the owner

  • The group 'staff' does not exist on the system

  • The file is owned by the 'root' user, so only root can modify it
