EXAM NUMBER : CWNA-108

EXAM NAME : Certified Wireless Network Administrator

QUESTIONS TYPE : Multiple-Choice

PASSING SCORES : 70%

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.

Main Areas Covered by CWNA:

- Radio Frequency (RF) Technologies

- Antenna Concepts

- Wireless LAN Hardware and Software

- Network Design, Installation, and Management

- Wireless Standards and Organizations

- 802.11 Network Architecture

- Wireless LAN Security

- Troubleshooting

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 has the ability to describe devices and
operations of current WLAN technologies.

The CWNA exam has no prerequisites; however, the following are recommended 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

The skills and knowledge measured by this examination are derived from a Job Task Analysis
(JTA) involving wireless networking experts (CWNEs) and professionals. The results of this JTA
were used in weighing the subject areas and ensuring that the weighting is representative of the
relative importance of the content.
When you pass the CWNA exam, you earn credit towards the CWSP, CWDP, CWAP, and
CWNE certifications and you earn the CWNA certification.

C. The antennas in the laptop have insufficient gain to detect the 5 GHz signals.
D. The access points are configured to disallow 5 GHz.
Correct Answer: C
QUESTION 60
A client complains of low data rates on his computer. When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11ac AP. Both the
client and AP are 2x2:2 devices. What is the likely cause of the low data rate issue?
A. Weak signal strength
B. CAT5e cabling run to the AP
