Possible bugs in Mock Exam 1, question about time

LFCS
#1

Hi guys, couple of questions here:

  1. At the exam we have 2 hours, but in Mock Exams it is only 60 min, so is this really similar to the real exam?

  2. Is passwd -l and usermod -L similar? because in Mock Exam 1 Q. 12 I’ve locked and unlocked password by usermod command but it failed and told me to use passwd I think this is the same.

  3. Q. 13 Define a resource limit for the user called jane. Set a limit for this user so that she can open no more than 30 processes. This should be a hard limit.
    I did like this and failed

#*               soft    core            0
#*               hard    rss             10000
#@student        hard    nproc           20
#@faculty        soft    nproc           20
#@faculty        hard    nproc           50
#ftp             hard    nproc           0
#@student        -       maxlogins       4
jane             hard    nproc           30

Is it bug?

Another one
A. Make sure that /usr/local/bin/script1.sh runs every Monday at 4AM

I did like this:

0 4 * * mon /usr/local/bin/script1.sh

and this is not passed, because the ‘answer’ is

0 4 * * 1 /usr/local/bin/script1.sh

but this is the same…
/etc/crontab →

# | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat

The next one:

A. Change the location of the error logs file. Errors should now be collected at /var/log/httpd_errors.log

My answer

ErrorLog "/var/log/httpd_errors.log"

not passed, because:

Change ErrorLog "logs/error_log" to ErrorLog "logs/httpd_errors.log"

btw how above answer is ok if

[root@centos-host httpd]# ll total 0 drwxr-xr-x. 2 root root 37 Aug 18 06:32 conf drwxr-xr-x. 2 root root 82 Aug 18 05:50 conf.d drwxr-xr-x. 2 root root 226 Aug 18 05:50 conf.modules.d lrwxrwxrwx. 1 root root 19 Nov 12 2021 logs -> ../../var/log/httpd

logs points to /var/log/httpd not /var/log …
Is anybody here?
