CWNA-106 Online Practice Questions and Answers

You are onsite with a client to perform a post-deployment site survey. When verifying a multiple channel VoWiFi deployment using a VoWiFi handset, which aspect is most important?

A. Performingprotocol analysis with a single wireless adapter that is scanning all channels in use

B. Testing a constant conversation orhandset tone while roaming from area to area, or performing an active survey

C. Configuring DSCP-to-802.11e QoS maps on the handset for each access category.

D. Verifying the VHT functionality to handle the call volume incurred by a single VoIP phone call.

What factors influence the distance that an RF signal can be effectively received? (Choose 3)

A. Transmitting station's power source

B. Receiving station's radio sensitivity

C. Free Space Path Loss

D. MAC layer encryption

E. Transmitting station'soutput power

F. Temperature in the Fresnel zone

ABC Company is planning toinstall a new 802.11ac WLAN, but wants to upgrade its wired infrastructure first to provide the best user experience possible. ABC Company has hired you to perform the RF site survey. During the interview with the network manager, you are told that the newEthernet edge switches will support VoIP phones and 802.11 access points, both using 802.3 PoE. After hearing this information, what immediate concerns do you note?

A. VoIP phones and 802.11 access points should not be powered by the same edge switch dueto distortion.

B. The edge Ethernet switches should support Ether-channel to get the best results out of the network.

C. If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal locations for

802.11 APs.

D. The power budget in the edgeswitches must be carefully planned and monitored based on the number of supported PoE devices.

As an RF wave propagates through space, the wave front experiences natural expansion that reduces its signal strength in an area.What term describes the rate at which this expansion happens?

A. MU-MIMO

B. Inverse square law

C. Fresnel zone thinning

D. Ohm's law

Which answer correctly completes the following sentence?

The WMM certification, created by the Wi-Fi Alliance, is based on the ___________ coordination function with support for ___________ QoS priority.

A. Hybrid, contention-based

B. Point, scheduled

C. Dynamic, distributed

D. Distributed,trigger-and-delivery

E. Enhanced, contention-free

In a Wi-Fi client configuration utility, what feature is most likely to be user configurable?

What parameter of the client drivershould be configured on a Windows computer to optimize moving from one AP to another within the ESS?

A. Band preference

B. Roaming threshold

C. ESSID selection

D. SSID selection

ABC Company is planning a point-to-multipoint outdoor bridge deployment with standalone (autonomous)

802.11 bridge units. 802.1X/EAP will be used for bridge authentication. A Linux-based RADIUS server will be used for authentication. What device in the bridge implementation acts as the 802.1X Authenticator?

A. The RADIUS server

B. All non-root bridges

C. A designated non-root bridge

D. The root bridge

E. The Ethernet switch

In an enterprise WLAN, what condition will prevent a dual-band VHT/HT client device from performing a fast and seamless transition (i.e. latency-sensitive applications are notdisrupted) between two access points that are managed by the same WLAN controller?

A. The current AP is using channel 1 and the new AP is using channel 40.

B. The SSID of the current AP does not match the SSID of the new AP.

C. The current AP supports only HT and the new AP is VHT capable.

D. The access points are hiding the SSID in Beacons and Probe Response frames.

What factors are taken into account when calculating theLink Budget of a point-to-point outdoor WLAN bridge link?

A. Antenna height

B. Transmit power

C. Operating frequency

D. Transmit antenna gain
