CWNP CWNA-107 Exam Questions

Question 6 of 97

What wireless networking term describes the increase of RF energy in an intentional direction with the use of an antenna?

Directed Radiation

Active Amplification

Passive Gain

Beam Digression

Correct Answer: C

Question 7 of 97

Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?

Dish and grid

Dipole and yagi

Grid and sector

Patch and panel

Correct Answer: D

Patch and panel antennas are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation. These types of antennas provide semi-directional coverage suitable for indoor environments where coverage needs to be managed more precisely, unlike dipole or yagi antennas which are less typical for such implementations.

Question 8 of 97

What statement about the beamwidth of an RF antenna is true?

Horizontal and vertical beamwidth are calculated at the point where the main lobe decreases power by 3 dB.

Vertical beamwidth is displayed (in degrees) on the antenna’s Azimuth chart.

When antenna gain is lower, the beamwidth is also lower in both the horizontal and vertical dimensions.

The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.

Correct Answer: A

Question 9 of 97

Which one of the following is not a factor considered when calculating the Link Budget for an outdoor point-to-point WLAN bridge link?

MU-MIMO capabilities of the bridges

Receive antenna gain

Transmit power

Operating frequency

Correct Answer: A

Question 10 of 97

What best describes WPA2 in relation to 802.11 wireless networks?

WPA2 is specified in the 802.11 standard as implementing CCMP/AES.

WPA2 is the standard that defines security for WLANs.

WPA2 is a certification created by the Wi-Fi Alliance that validates devices correctly implement CCMP/AES.

WPA2 is the second version of WPA and it enhances security through the use of TKIP instead of WEP.

Correct Answer: C

WPA2 is a certification created by the Wi-Fi Alliance that validates devices correctly implement CCMP/AES. The Wi-Fi Alliance developed WPA2 to ensure interoperability and security in wireless networks, and it implements CCMP/AES for enhanced security measures over previous standards.
