PassQuestion has created a comprehensive set of Certified Wireless Network Administrator CWNA-109 Exam Questions, which are specifically designed to aid in effective preparation. Using these CWNA-109 exam questions, candidates will be fully prepared and will have the ability to clear their exams on their first attempt. The Certified Wireless Network Administrator CWNA-109 Exam Questions have been meticulously crafted based on the pattern of the real exams. This similarity in pattern will provide candidates with a familiar setting, allowing them to approach the CWNA Certification with greater confidence. 

Certified Wireless Network Administrator (CWNA)

The CWNA certification serves as the foundational wireless LAN certification in the CWNP Program. To secure this certification, you're required to appear for the CWNA exam at a Pearson Vue Testing Center and secure a score of 70% or more. For instructors, the passing score is 80% or higher. Regardless of your preparation method for the CWNA exam, we recommend beginning with the exam objectives. These provide a comprehensive list of the skills assessed in the exam. The CWNA certification remains valid for three years. You can renew it by passing one of the professional level certification exams (CWSP, CWDP, CWAP) before your CWNA expires, which will renew your CWNA for another three years. Alternatively, you can retake the current version of the CWNA exam.
