The latest exam code for this certification is CWNA-109. To ensure you are fully prepared and able to answer real CWNA-109 exam questions, Passcert offers the most recent Certified Wireless Network Administrator CWNA-109 Dumps that are designed to provide you with the knowledge and understanding required to successfully pass the exam. With these exceptional Certified Wireless Network Administrator CWNA-109 Dumps, you are guaranteed a brilliant success in the CWNA exam on your first attempt.
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. When you pass the CWNA exam, you earn credit towards the CWSP, CWDP, CWAP, and CWNE certifications and you earn the CWNA certification.
The Certified Wireless Network Administrator (CWNA) understands standards and operations of 802.11 wireless networks. Responsibilities include deploying, managing, monitoring, and basic troubleshooting of these networks. The CWNA can describe devices and operations of current WLAN technologies.
The CWNA exam has no prerequisites; however, the following are recommended knowledge and experience before attempting the CWNA 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
