Just like our LPIC-1 Study Guide, this book contains detailed explanations for all of the LPIC-2 exam objectives, along with example questions, flashcards for self-study, and practice questions. The purpose of this book is to help you pass both of the LPIC-2 exams, 201 and 202. These exams cover more advanced topics than the LPIC-1 exam, such as the Linux kernel, system startup, filesystems, network operations, DNS servers, web servers, file servers, email servers, network client management, and security. This book will walk you through all of these topics, helping prepare you for the LPIC-2 exam questions.

The purpose of the Linux Professional Institutes (LPI) LPIC-2 program is to define the basic knowledge required to administer small to medium-sized mixed (Microsoft and Linux) networks, focusing on the Linux operating system. The program guides professionals wishing to build on knowledge gained from the LPIC-1 program.

It is expected that you have already passed the LPI Linux Essentials (optional) exam and the LPIC-1 (or CompTIA Linux+) exam and have at least five years experience in administering a Linux server(s) in a mixed network environment.

The successful LPIC-2 candidate should have at a minimum knowledge and experience concerning the following topics:
