B. You can create files in this directory.
C. You can execute the file named script.
D. You can edit and save files in this directory.
E. You can create sub-directories in this directory.
F. You change permissions on files in this directory.
Answer: CD


不明白为啥D也是答案.  test1 不是 754吗? 怎可能改除了script1之外的档?




186. You have two users that are abusing the system by creating scripts that run periodically as cron jobs that
continuously harass other users. You have been instructed to disable cron for these two users.
Which three (what?) describe how to configure the server to block specific users from using cron? (Choose
three.)
A. Protect the crontab command so that only privileged users are allowed to run it.
B. Remove the /etc/cron.d/cron.allow file and add their names to /etc/cron.d/cron.deny
C. Remove the crontabs associated with each offending user in the /var/spool/cron/crontabs director.
D. Remove their names from the /etc/cron.d/cron.allow file and add their names to /etc/cron.d/cron.deny
E. Add their names to the /etc/cron.d/cron.deny file. It is not necessary to remove their names from the
/etc/cron.d/cron.allow file.
F. Remove their names from the /etc/cron.d/cron.allow file only. If the default /etc/cron.d/cron.deny exists, it
does not need to be changed.
Answer: BDF

为何E不行? 不是同时存在cron.allow & cron.deny时会被deny access吗?

是不是drwxr-xr-T的原因？
