CWNA ACTUAL Exam Questions and
CORRECT Answers
Which one of the following organizations performs compatibility testing of 802.11 hardware?
a. IETF
b. Wi-Fi Alliance
c. FCC
d. MIC - CORRECT ANSWER - B is correct. The Wi-Fi Alliance performs compatibility
testing against 802.11 wireless devices based on 802.11 standards or subsets of those standards.
Within the 802.11 standard to understand the details of Beacon frame options. What organization
provides a website that you can use to gain access to the 802.11 standard?
a. IEEE
b. FCC
c. ITU-R
d. Wi-Fi Alliance - CORRECT ANSWER - A is correct. The IEEE website can be used to
access 802.11 standard documents. They are free after a period of six months passes from their
ratification.
Your organization has decided to install a WLAN in their warehouse facility. The warehouse is
approximately 400 meters from the main building and it has no Ethernet or other wired network
connection run between the main building and the warehouse. Which one of the following
wireless technologies will most likely be used to provide a link between the main building and
the warehouse?
a. WPAN
b. WMAN
c. WWAN
,d. WLAN - CORRECT ANSWER - D is correct. WLAN bridges will most likely be used
in this scenario as it is a shorter distance link than required by WWAN solutions.
What IEEE standard specified a port-based authentication solution?
a. 802.3
b. 802.1X
c. 802.1Q
d. 802.1D - CORRECT ANSWER - B is correct. The 802.1X standard specified port-based
authentication and is used in enterprise WLAN security solutions.
What frequency bands are most commonly used by WLAN hardware?
a. 2.4 GHz and 5 GHz
b. 2.4 GHz and 100 GHz
c. 5 GHz and 10 MHz
d. None of these - CORRECT ANSWER - A is correct. While the sub-1 GHz, TV
whitespace, and 60 GHz bands are used, by far the most commonly utilized bands are 2.4 GHz
and 5 Ghz.
What is indicated when a device is certified by the Wi-Fi Alliance as 802.11b/g/n certified?
a. It is a 5 GHz-only device
b. It is a 2.4 GHz-only device
c. It supports WPA2-Enterprise
d. It supports WPA-Personal - CORRECT ANSWER - B is correct. When the certificate
indicates only 802.11b/g/n, it indicates 2.4 GHz-only support as these amendments are all
operable in 2.4 GHz and, if 5 GHz were supported, 802.11a would be listed as well.
,What is based on an IETF document and defines communications between a lightweight access
point and a controller?
a. CAPWAP
b. 802.1Q
c. EAP
d. RADIUS - CORRECT ANSWER - A is correct. CAPWAP and LWAPP are defined in
IETF RFCs. They both specify methods of communications between an access point and a
controller.
What Wi-Fi Alliance certification ensures proper VoIP communications even when moving from
one access point to another?
a. WMM
b. Voice-Personal
c. Voice-Enterprise
d. WPS - CORRECT ANSWER - C is correct. Voice-Enterprise is a certification that
ensures proper communications for VoIP across a WLAN even when roaming between access
points. Voice-Personal only ensures such communications when connected to a single AP.
You have purchased an AP for a specific regulatory domain. You now that you cannot turn up the
transmit power beyond a specific level. What is the likely cause of this behavior?
a. Firmware problems
b. Radio failure
c. Regulatory constraints
d. IEEE constraints - CORRECT ANSWER - C is correct. One area of constraint imposed
by regulatory agencies is output power. When an AP ships for a specific regulatory domain, those
constraints are enforced.
, In what mode is an access point operating when clients connect to it in order to gain access to a
printer?
a. Distribution
b. Core
c. Access
d. None of these - CORRECT ANSWER - 1C is correct. When an access point is in access
mode, it is providing access to the resources to which it is connected for clients connected to the
access point.
What denotes the strength of an RF wave or signal?
a. Wavelength
b. Phase
c. Amplitude
d. Modulation - CORRECT ANSWER - C is correct. The amplitude is the strength or
power of the RF wave.
2. What is decreased as the frequency of a wave increases?
a. Wavelength
b. Phase
c. Modulation
d. Coding - CORRECT ANSWER - A is correct. As the frequency increases, the
wavelength decreases. Alternatively, as the wavelength increases, the frequency decreases.
3. What RF behavior is similar to light waves as seen in a mirror?
a. Absorption
b. Attenuation
