Take the latest editions of the challenging RHCSA and RHCE certification exams with confidence.
This comprehensive self-study guide clearly explains what you need to know—and gets you fully prepared—for the RHCSA and RHCE certification exams. Written by a pair of Linux certification experts and experienced authors, this new edition has been thoroughly revised for Red Hat Enterprise Linux 8 and provides complete coverage of all exam objectives.
RHCSA/RHCE Red Hat Enterprise Linux 8 Certification Study Guide, Eighth Edition (Exams EX200 & EX294) is an integrated study system based on proven pedagogy. Each chapter includes step-by-step exercises, special "Exam Watch" and "On the Job" sidebars, "Two-Minute Drills," self-tests, and hands-on lab questions. The companion website contains searchable glossaries, downloadable virtual machine files, four complete lab-based practice exams (two for each exam), and 100+ lab-based exercises with answers and explanations.
Today, you can use Linux on everything from laptops and mobile devices to servers and mainframes. This makes Linux a versatile option for many different situations. Linux is also known for its strong security. Because it is open source, any security problems can be quickly found and fixed by the community. Linux also has strong rules about permissions and access, which makes it tough for harmful software to break in. Regular updates also help keep Linux safe and secure.
Linux also provides good support for virtualization, which lets users create and manage virtual machines (VMs) efficiently. With tools like Kernel-based Virtual Machine (KVM) and Xen, Linux allows users to run more than one operating system at the same time on a single machine. This is really useful in server environments, where virtualization makes things like software deployment and resource management easier.
On top of this, Linux is the go-to platform for container technologies like Docker and Kubernetes. Containers create isolated environments for applications, making them easier to move and run on different systems. Linux’s built-in features, such as namespaces and cgroups, are the backbone of containerization. These features make it easier to manage resources, isolate processes, and scale up. By bringing together Linux and containerization, software development and deployment have become faster and more efficient.
Having discussed the diverse capabilities and advantages of Linux, it’s essential to recognize the challenges that come with mastering it. Red Hat exams, for instance, are tough, and not many first-time test-takers pass the RHCSA exam. But don’t let that scare you. While passing isn’t guaranteed, this book is designed to help you prepare for and hopefully pass the RHCSA exam. The skills described in this book can also help you in your job as a Linux administrator. However, this book isn’t a replacement for the Red Hat prep courses, which we’ll talk about soon.
