A Linux administrator needs to set the permissions on a server. The administrator wants to have the files within the directory set to read-write permissions and the directory set to read-write…

The correct answer is D. umask 0077. Setting the umask to 0077 causes new directories to be created with 0777–0077 = 0700 (rw‑x only for the owner) and new files with 0666–0077 = 0600 (rw only for the owner), which matches the requirement of read/write on files and read/write/execute on the directory.
