CWNA Exam (PW0-104) Objectives
Introduction
When you pass the CWNA exam, you earn credit towards the CWSP, and CWNE certifications.
This exam measures the candidate’s ability to understand the fundamentals of RF behavior and to describe the
features and functions of WLAN components. Also tested are the skills needed to install, configure, and
troubleshoot WLAN hardware peripherals and protocols.
The skills and knowledge measured by this examination are derived from a survey of wireless networking experts
and professionals. The results of this survey were used in weighing the subject areas and ensuring that the weighting
is representative of the relative importance of the content.
The following chart provides the breakdown of the exam as to the weight of each section of the exam.

CWNP Authorized Materials Use Policy
CWNP does not condone the use of unauthorized 'training materials', aka 'brain dumps'. Individuals who utilize
such materials to pass CWNP exams will have their certifications revoked. In an effort to more clearly
communicate CWNP's policy on use of unauthorized study materials, CWNP directs all certification candidates to
the CWNP Candidate Conduct Policy at:
