Free CWNA-108: Certified Wireless Network Administrator Exam Questions and Answers
Certified Wireless Network Administrator is exam CWNA-108, part of the CWNP wireless certification programme. The professional exams share one format exactly: 60 multiple-choice and multiple-answer questions in 90 minutes, 70% to pass — 80% if you are certifying as an instructor — sat through CWNP remote proctoring or at a Prometric centre, in English only, and valid for three years. CWNA is the hinge of the programme: it must be passed before CWSP, CWDP or CWAP, which can then be taken in any order. CWNP versions its codes as it revises each exam, so a number here may have been superseded by a later revision of the same certification.
