Self Test

The format of this book and chapter is different from other Practice Exams book in the McGraw-Hill series. Each chapter will include a brief overview of several different objectives on the Red Hat Certified System Administrator (RHCSA) and Red Hat Certified Engineer (RHCE) exams. This chapter starts with a description of the exams. It continues with an overview of the 64-bit hardware required to set up the virtual machine (VM) software covered by the RHCSA exam. It also includes instructions for how to load the preconfigured VMs compressed on the compressed VMs that are available for download from McGraw-Hill Professional Media Center Download web page. For additional download instructions, please see the "About the Download" appendix at the end of this book.

The Red Hat exams are an advanced challenge. While this book provides labs and sample tests to help you prepare for the RHCSA and RHCE exams, it provides minimal explanation of exam objectives. If you want additional information, I encourage you to start with the RHCSA/RHCE Red Hat Linux Certification Study Guide (Exams EX200 & EX300), 6th Edition. In addition, Red Hat offers several courses to help prepare for these exams, as described in the front matter.

To prepare for the Red Hat exams, you need a physical 64-bit system that can support hardware-based virtualization. The objectives for the Red Hat exams specify virtualization. Red Hat's default virtual machine (VM) solution is the Kernel-based Virtual Machine (KVM). Red Hat offers KVM software that can host VMs only on its 64-bit releases. (As options that support "nested" virtualization are not free, they have not been tested for this book.)

In this chapter, you'll set up RHEL 6 on such a 64-bit system, with KVM in place. (Yes, based on a related RHCSA objective, there will be a lab where you'll demonstrate how to install KVM-based software after installation is complete.) You'll then use the compressed virtual machines available on the MHP Media Center download web page. As they're based on the same source code used for RHEL 6, "rebuild" distributions such as the Community Enterprise Operating System (CentOS) and Scientific Linux (SL) should work in the same fashion. In general, most tasks can be performed on the VMs. But there are at least two exceptions when it's better to run a task on the physical system: when you create an installation HTTP/FTP server later in this chapter and when you set up a Virtual Network Computing (VNC) client in Chapter 9. Other labs may also use the physical host system.

For the purpose of this book, I'll run most commands as the Linux administrative user, root. Logging in as the root user is normally discouraged unless you're administering a computer.

However, because the RHCSA and RHCE exams test your administrative skills, it's appropriate to run commands in this book as the root user. But you also need to know how to set up regular users with partial or full administrative privileges.

As with the rest of the book, no guarantees are provided for the downloadable VMs.

All chapters in this book include a brief discussion of relevant exam objectives. Every objective on both the RHCSA and RHCE exams is covered in one or more of the 17 chapters in this book. Three RHCSA objectives are covered in this chapter. Just be aware, Red Hat has been known to modify objectives from time to time, so be sure to review them as you go through this book. As of this writing, the objectives were just moved to the following URLs: www.redhat.com/training/courses/ex200/examobjective and www.redhat.com/training/courses/ex300/examobjective.

The RHCSA and RHCE Exams

The first Red Hat exams were given in 1999. And they've evolved since then. Until 2003, there was actually a multiple-choice component to the RHCE exam. At that time, the three-part exam was 6.5 hours long.

In 2009, Red Hat removed the requirement to install RHEL on a bare-metal system. They've since refocused the requirement for installation on a VM. In addition, there is no longer a separate troubleshooting section on either exam.

The RHCSA was introduced with the release of RHEL 6, as a replacement for the Red Hat Certified Technician (RHCT) exam. The RHCT was a complete subset of the RHCE. The RHCSA is different. Although the topics are closely related, they are separate from those now listed for the RHCE.

The Exam Experience

Red Hat's certification tests are hands-on exams. As such, they are respected throughout the industry as a sign of genuine practical knowledge. When you pass a Red Hat exam, you will stand head and shoulders above the candidate who has passed only a "standard" multiple-choice certification exam.

When time starts, you'll be faced with a live system. You'll be given actual configuration problems associated with the items listed in the exam objectives for each certification. Naturally, this book is dedicated to helping you master the skills associated with those objectives.

While you won't have Internet access during the exam, you will have access to online documentation such as man and info pages as well as documentation in the /usr/share/doc/ directories, assuming appropriate packages are installed.

In addition, Red Hat provides the exam in electronic format. While the basic instructions may be in a local language such as English, the RHCSA and RHCE exams are available in 12 different languages: English, Simplified Chinese, Traditional Chinese, Dutch, French, Italian, Japanese, Korean, Portuguese, Russian, Spanish, and Turkish. (If you're unsure, contact Red Hat training at US 1-866-626-2994, or via www.redhat.com/training/.)

Red Hat also has prep courses for both exams. The outlines for those courses are available from www.redhat.com. While this book is not intended as a substitute for such courses, it is consistent with the outline of those courses. This book covers the objectives associated with each of these exams.

The RHCSA Exam

The RHCSA exam allows you to demonstrate your ability to configure live physical and virtual systems for networking, security, custom file systems, package updates, user management, and more. In essence, the RHCSA exam covers skills required to configure and administer a Linux workstation in the enterprise.

You have two and a half hours to complete the tasks given on the RHCSA exam. You complete the tasks by configuring a live RHEL system. Any changes that are made must survive a reboot. When you've completed the given tasks, the person grading the exam will see if the system is configured to meet the requirements. For example, if you're told to "create, delete, and modify local user accounts," it doesn't matter if the associated configuration file has been modified with the vi editor...
