What is the purpose of the umask value?

It sets the default permissions for new files and directories.

It sets the maximum permissions a user can have on any file.

It sets the owner and group for new files.

It sets the special permissions (setuid, setgid, sticky) for new files.

An administrator runs `ls -l` and sees the following output: `drwxr-sr-x 2 alice staff 4096 Mar 12 10:30 reports`. What can be determined about the directory?

The sticky bit is set, and only the owner can delete files.

The setgid bit is set, and new files will inherit the `staff` group.

The directory is owned by `staff` and the group is `alice`.

The setuid bit is set, and new files will inherit the `alice` user.
