Wymagania wstępne

The CWNA has no prerequisites; however, the following are recommended knowledge and experience before attempting the CWNA training and exam:

  • Basic knowledge of networking (routers, switches, cabling, etc.)
  • Basic knowledge of TCP/IP
  • At least 1 year of work experience with wireless LAN technologies
Poziom trudności
Czas trwania 4 dni
Certyfikat

The participants will obtain certificates signed by Compendium CE (course completion).

The CWNA certification is a foundational level wireless LAN certification for the CWNP Program. To earn a CWNA certification, you must take the CWNA exam at a Pearson Vue Testing Center and pass with a 70% or higher. Instructors must pass with a 80% or higher. However you choose to prepare for the CWNA exam, you should start with the exam objectives, which cover the full list of skills tested on the exam.  The CWNA certification is valid for three (3) years. To recertify, pass one of the professional level certifications exams (CWSP,CWDP, CWAP) BEFORE your CWNA expires. By doing so, the CWNA will be renewed for another three (3) years. Or retake the current version of the CWNA exam.

While the Certified Wireless Specialist (CWS) and Certified Wireless Technician (CWT) certifications are not a required prerequisite to the CWNA certification, it is highly recommended. It will provide a solid learning foundation before continuing to pursue the CWNA.

CWNA exam is available through the Pearson VUE test centers.

Each participant in an authorized CWNP CWNA training held in Compendium CE will receive a free CWNA-109 Certified Wireless Network Administrator Exam voucher.
