LPI Linux Certification in a Nutshell (In a Nutshell (O'Reilly)) Review

LPI Linux Certification in a Nutshell (In a Nutshell (O'Reilly))
Average Reviews:

(More customer reviews)
The first thing I want to say about reading this book is : I passed! Certification books serve four purposes: first, they serve as a way to prepare for computerized certification exams. Second, they provide a 'training plan' for learning the objectives in the certification. Third, can a book explain system administration concepts while limiting a reader's exposure to difficult, elusive topics until later? Fourth, can a book like this still be useful post-certification?
Part One (covering the 101 test) contained generous amounts of examples for text-processing commands and a really top notch discussion of permissions, ownership, booting and documentation. Helpfully, 'need to know' boxes are scattered throughout the book to indicate how important a topic is on the test. Frequently, the author will point out that although he explained a certain topic in depth, it won't be covered in depth on the test. I really appreciated that, although I found that the actual test covered certain topics (such as X Windows) in much more depth than Dean leads us to believe. One thing, by the way, to remember, is that often the book gives only the 5 or 6 most popular switches for each command. If you learned about these commands only from this book, you might be overlooking some important switches. I found this especially to be true when Dean discussed user management. I consider usermod 'g and usermod 'G to be really important commands, but this book didn't even mention them. On the other hand, Dean gave an explanation of regular expressions which was quite adequate for the purposes of this book. Although omitting some switches proved exasperating at times, the simplified view of the commands can be helpful for linux newbies.
Part Two (covering 102 test) covered a lot more ground: Apache, sendmail, nfs, dns, tcp-ip; heck, books have been written on each of those topics. The book covered well these topics in particular: compiling a kernel, troubleshooting tcp-ip and using rpm's. I found his discussion of Debian package management to be hard to follow, although that may be because I've never used it before in real life (but watch out! The test covers this in depth!). The book's discussion of network services (nfs, sendmail, apache, samba) was shallow at best, but I doubt anyone would rely on such a book for maintaining a web server, for example. But it provided some of the basics at least. The section on X Window was succinct and helpful. Also, some of the information presented is outdated, at least on Red Hat's latest distribution. Red Hat, for example, no longer uses inetd for startup, and some of the directory paths have since changed. These are minor quibbles, and one of the challenge of passing a certification like this is asking yourself: should I be learning things for the exam that are no longer accurate or relevant in current distributions? Certifications test the knowledge available at the time of test creation, when in reality new applications are being added and processes streamlined every day.
The book contains lots of sample multiple choice items, review questions and exercises. The multiple choice items didn't really add much to the book, but I frequently referred to the review questions. (Remember, the LPI exam has fill-in-the-blanks questions). Don't overlook the excellent 'highlighter's index' at the back of the book.
Two minor quibbles. First, the cover is not very strong and is bent, torn and curled over. The other is that the LPI exam objectives are not located at the front or back of the book. Rather, the table of objectives for 101 are in the front, and objectives for 102 are in the middle. I referred to this table constantly to see the amount of weight LPI was giving to a particular topic. Also, because the table of contents follow the LPI learning objectives (probably a smart thing), it is often difficult to find documentation about a certain command. For that I might recommend Linux in a Nutshell , 3rd Edition, which serves as a comprehensive index of commands and system utilities. It is excellent. Also, General Linux I Exam Prep (Exam: 101) by Dee Ann LeBlanc (published in 2000), is an extremely helpful book (and available for significantly reduced price used). Although it was one of the first to market and didn't address the LPI objectives explicitly, the exercises and presentation of material are every bit as good as Dean's book. Keep in mind also that LPI Linux Certification is not sufficient in and of itself. You will probably end up referring to other books such as Matt Welsh's Running Linux, Olaf Kirch's Linux Network Administrator's Guide or the unbelievably good Rute User's Tutorial and Exposition .

It's rare to find a book that covers the exam material so well that you only need to buy one book to pass the test - but this one is an exception. Not only does it cover the material well, it is truly an easy read. The test was relatively difficult because of it's breadth of testing topics but I passed with an 857 (700 required to pass) and I credit it to this guide.
Buy this book + read it AND understand it = pass the test.

A+ Certification All-in-One Exam Guide Review

A+ Certification All-in-One Exam Guide
Average Reviews:

(More customer reviews)
Ok. There have been some negative reviews about this book and I wanted to add my 2 cents to this. It is possible to pass the A+ Certification exams using little more than this book. I should know, as I personally did it. It wasn't easy, it took a lot of studying, and my scores weren't the greatest, but I did pass using little more than the book and practice exams that came on the CD with the book. I got a 574 on the Core and a 619 on the OS. Not impressive, but I'm not saying this book will make you incredible, I'm just saying you can pass using very little besides this book.
My strategy went as follows:
1) Read the book staight through for about 2 weeks, reading 150-300 pages a day while TAKING NOTES. Writing the information physically on a sheet of paper helps a lot.
2) Memorize the notes you took. Ingrain everything you think is important into your brain. And this isn't just necessarily facts. Its the concepts behind the facts. This book did a really good job with those and because of it, I was able to correctly guess a good number of the questions on the OS exam that would have otherwise stumped me.
3) Read the Objectives off CompTIA's website! This will help you catch anything that the book missed.
4) Take the practice exams with the book. I left one exam for Core and OS until I felt like I was done studying and just wanted a confidence boost. Don't underestimate this. Attitude can make a big difference. Also, don't underestimate the value of the practice exams. They are about as tough as the real thing. Some questions easier, some harder, but overall about the same difficulty.
5) Retake those practice exams until everything you missed is ingrained into your mind. There were at least 6 or 7 questions on each test I ONLY got right because I remembered getting them wrong on the practice exams.
6) Find any practice exams or questions online that you can. I opted to use some free ones, many of them only being about 10 questions or so, but they gave me other perspectives and ways to ask questions that I hadn't seen.
7) If you can, get some hands on experience. If the book is going over the Recovery Console, do it yourself. If you can picture doing things on the computer in your mind, it will help when it comes to test time.
8) Good luck! The more info you can get, the better, but with this book and your wits, you should at least be able to do better than I did. It took me about a month total of solid studying, and this is from someone who one year ago didn't even know how to build a PC, and had only made 3 before taking the test.
So overall, I think this book is worth it. I can't say anything about the competition because I haven't used it, but for about 50 bucks, this book is well written and easy to read, tells you at least MOST of what you know while being a little entertaining at the same time, and will come in handy as a great reference book. I've given it 5 stars not because its the most amazing thing written, but that it did what it was supposed to: get me to pass the A+ Exam.
I hope this review is helpful to those of you considering getting your certification!
