Sinopsis
If you have purchased this book or if you are thinking about purchasing this book, you probably have some interest in taking the CWNA® (Certified Wireless Network Administrator) certifi cation exam or in learning more about what the CWNA certification exam is about. We would like to congratulate you on this fi rst step, and we hope that our book can help you on your journey. Wireless networking is one of the hottest technologies on the market. As with many fast-growing technologies, the demand for knowledgeable people is often greater than the supply. The CWNA certifi cation is one way to prove that you have the knowledge and skills to support this growing industry. This Study Guide was written with that goal in mind.
This book was written to help teach you about wireless networking so that you have the knowledge needed not only to pass the CWNA certifi cation test, but also to be able to design, install, and support wireless networks. We have included review questions at the end of each chapter to help you test your knowledge and prepare for the test. We have also included labs, white papers, videos, and presentations on the book’s website (www.sybex.com/go/cwna3e) to further facilitate your learning.
Before we tell you about the certifi cation process and requirements, we must mention that this information may have changed by the time you are taking your test. We recommend that you visit www.cwnp.com as you prepare to study for your test to determine what the current objectives and requirements are.
If you have ever prepared to take a certifi cation test for a technology that you are unfamiliar with, you know that you are not only studying to learn a different technology, but probably also learning about an industry that you are unfamiliar with. Read on and we will tell you about CWNP.
CWNP is an abbreviation for Certifi ed Wireless Network Professional. There is no CWNP test. The CWNP program develops courseware and certifi cation exams for wireless LAN technologies in the computer networking industry. The CWNP certifi cation program is a vendor-neutral program.
The objective of CWNP is to certify people on wireless networking, not on a specifi c vendor’s product. Yes, at times the authors of this book and the creators of the certifi cation will talk about, demonstrate, or even teach how to use a specifi c product; however, the goal is the overall understanding of wireless, not the product itself. If you learned to drive a car, you had to physically sit and practice in one. When you think back and reminisce, you probably do not tell someone you learned to drive a Ford; you probably say you learned to drive using a Ford.
There are seven wireless certifi cations offered by the CWNP program: CWTS: Certified Wireless Technology Specialist CWTS is an entry-level enterprise WLAN certifi cation and a recommended prerequisite for the CWNA certifi cation. This certifi cation is geared specifi cally toward both WLAN sales and support staff for the enterprise WLAN industry. The CWTS certifi cation verifi es that sales and support staff are specialists in WLAN technology and have all the fundamental knowledge, tools, and terminology
to more effectively sell and support WLAN technologies.
to more effectively sell and support WLAN technologies.
CWNA: Certified Wireless Network Administrator The CWNA certifi cation is a foundation-level Wi-Fi certifi cation; however, it is not considered an entry-level technology certifi cation. Individuals taking this exam (exam PW0-105) typically have a solid grasp on network basics such as the OSI model, IP addressing, PC hardware, and network operating systems. Many candidates already hold other industry-recognized certifi cations, such as the CompTIA Network+ or Cisco CCNA, and are looking for the CWNA certifi cation to enhance or complement existing skills.
CWSP: Certified Wireless Security Professional The CWSP certifi cation exam (PW0-204) is focused on standards-based wireless security protocols, security policy, and secure wireless network design. This certifi cation introduces candidates to many of the technologies and techniques that intruders use to compromise wireless networks and that administrators use to protect wireless networks. With recent advances in wireless security, WLANs can be secured beyond their wired counterparts.
CWDP: Certified Wireless Design Professional The CWDP certifi cation exam (PW0-250) is a professional-level career certifi cation for networkers who are already CWNA certifi ed and have a thorough understanding of RF technologies and applications of 802.11 networks. This certification prepares WLAN professionals to properly design wireless LANs for different applications to perform optimally in different environments.
CWAP: Certified Wireless Analysis Professional The CWAP certifi cation exam (PW0-270) is a professional-level career certifi cation for networkers who are already CWNA certifi ed and have a thorough understanding of RF technologies and applications of 802.11 networks. This certification provides an in-depth look at 802.11 operations and prepares WLAN professionals to be able to perform, interpret, and understand wireless packet and spectrum analysis.
CWNE: Certified Wireless Network Expert The CWNE certifi cation is the highest-level certifi cation in the CWNP program. By successfully completing the CWNE requirements, you will have demonstrated that you have the most advanced skills available in today’s wireless LAN market. The CWNE certifi cation requires CWNA, CWAP, CWDP, and CWAP certifi cations. To earn the CWNE certifi cation, a rigorous application must be submitted and approved by CWNP’s review team.
