Subtitles of the Movie

Now we've reached the wrap-up movie for this course. In this course, we've addressed all of the topics associated with the Red Hat Certified Technician exam. We started with the prerequisites as defined in the RHCT Exam Prep Guide and that's shown at the URL shown here. Yes, that's the correct URL, despite the RHCE in the address. The prerequisites apply to both RHCT and RHCE exams and what you've learned in this course also applies when you study for the RHCE. In any case, we've followed up by covering the elements of Red Hat's RHCT prep course, RH133. We finished this course by analyzing the two parts of the RHCT exam, troubleshooting and system maintenance followed by installation and configuration. The troubleshooting and system maintenance section requires that you solve five problems within one hour. The problems are associated with the following skills, you need to know how to boot systems into different run levels. That's typically done from the GRUB menu. You need to demonstrate that you can diagnose and configure misconfigured networking, as well as host name resolution issues. There are a number of command line tools you could use and in many cases you can address these problems with the network configuration tool. You need to know how to configure the X window as well as the desktop environment. If you know Linux, you know these are two separate issues. You need to demonstrate that you can add new partitions, file systems, and swap space. While this is best done during the installation process, the fact that this exists in the troubleshooting and system maintenance section means you have to know how to do this after Linux is installed, and to do all of this, you generally need to use standard command line tools to analyze problems and configure your system. Remember, you have to solve all five problems that are presented to you in order to pass this part of the exam. The installation and configuration section gives you two hours to demonstrate most or all of the following skills and I've split them up into three pages. You need to know how to install Red Hat Enterprise Linux over a network. When you do, you need to implement a custom partitioning scheme, whatever is presented to you during your exam. You should know how to configure printing, whether it be from a local printer or something over a network. A good linux administrator knows how to configure task scheduling. That's typically associated with the cron and AT daemons. When you configure a system as a work station, RHCTs are expected to know how to attach such systems to a network information service or an LDAP, lightweight directory access protocol server. RHCTs know how to configure the automounter, which is associated with the autofs daemon. RHCTs are expected to add and manage users and groups, know how to configure quotas for users and groups, and set access control lists, ACLs, for files and directories associated with these users and groups. As users sometimes need to work in groups, you need to know how to configure file systems and by implication, in my opinion, special directories for collaboration. Of course, when you use Red Hat systems, you have to install and update packages using the RPM command. And most importantly, you need to know how to properly update the kernel package and remember, when you're updating a kernel, you install, you never upgrade. RHCTs are expected to know how to configure updates and installations, Yum and the Pup commands. RHCTs need to know how to modify the system bootloader, which is associated with the GRUB configuration file. It's easiest to implement software right during the installation process, but with the skills you learned in this course, you should know how to do this after installation as well. You're expected to know how to modify and set kernel run time parameters and that's typically done in the etc slash sysctl.conf configuration file. And finally, you need to know how to use scripting to automate maintenance tasks and examples of this are available in the etc slash crontab configuration file. There are only about eight hours of videos associated with this course and the Red Hat prep course for the RHCT includes 32 hours of instruction, but the RH133 course, at least in the U.S., costs $2,500, so I'm glad you've made the choice to try out this course, perhaps in prep for the RH133 or, I believe, with some self-study, you can use this course to pass the RHCT exam. Thank you and good luck.
