Question 1

What statement about the IEEE 802.11e QoS facility is true?

A. Toimprove efficiency, Block Acknowledgments arerequired for Voice and Video WMM queues. B. Four 802.1p user priorities are mapped to eight 802.11 transmit queues. C. When the Voice queue has frames awaiting transmission, no data will be transmitted from the Best Effort queue. D. 802.11 control frames are assigned to the 802.11 EF priority queue. E. 802.11 QoS is achieved by giving highpriority queues a statistical advantage at winningcontention.

Correct Answer: E

Question 2

What statements accurately describe the RF cables and connectors that are used in an
802.11 WLAN system? (Choose 3)

A. Two RF connectors of the same type (e.g. SMA), manufactured by different companies, may vary in specifications. B. Every RF connector causes insertion loss. C. RF cables have upper and lower frequency range specifications. D. 75 and 125 ohms are the typical impedances of 802.11 WLAN connectors. E. Large diameter RF cables cause greater loss than smalldiameter cables.

Correct Answer: A,B,C

Question 3

To ease user complexity, your company has implemented a single SSID for all employees.
However, the network administrator needs a way to control the network resources that can be accessed by each employee based on their department.
What WLAN feature would allow the network administrator to accomplish this task?

A. SNMP B. WPA2 C. WIPS D. RBAC E. IPSec F. VRRP

Correct Answer: D

Question 4

What statement about 802.11 WLAN performance is true?

A. In 802.11ac, changing the security mechanism from WPA2-Personal toWPA2-Enterprise will enable the VHT MCS rates. B. BSS support for 65 KB A-MPDUs willincrease the maximum data rate available to client devices. C. Use of larger frame sizes results in greater throughput in low interference environments. D. Compared to an Independent BSS, an Infrastructure BSS can provide almost twice the throughput between wireless nodes.

Correct Answer: C

Question 5

You were previously onsite at XYZ's facility to conduct a pre-deployment RF site survey.
The WLAN has been deployed according to your recommendations and you are onsite again to perform a post-deployment validation survey.
When performing this type of post-deployment RF site survey for VoWiFi, what are two steps that must be performed? (Choose 2)

A. Coverage analysis to verifyappropriate coverage and roamingboundaries B. Application analysis with anactive phone call on a VoWiFi handset C. Frequency-band hopping analysis to detect improper RF channel implementations D. Spectrum analysis to locate and identify RF interference sources E. Protocol analysis to discover channel use on neighboring APs

Correct Answer: A,B

Question 6

When a client moves to a new BSS within an ESS, whatstep is a part of the 802.11 reassociation process?

A. The current access point informs the IP gateway of the reassociation. B. The client station transmits a Reassociation Request frame to its currentaccess point. C. The current access point triggers theclient's reassociation service. D. The new access point transmits a Reassociation Response to the client station with a status value.

Correct Answer: D

Question 7

Which of the following frequency ranges are specified for use by IEEE 802.11 radios?
(Choose all that apply.)

A. 5.725 - 5.875 GHz B. 902 - 928 MHz C. 5.470 - 5.725 GHz D. 5.15 - 5.25 GHz E. 2.4000 - 2.4835 GHz

Correct Answer: A,C,D,E

Question 8

ABC Company has just purchased a 6 dBi patch antenna. After performing some testswith the 6 dBi antenna, they have concluded that more antenna gain is needed to cover their outdoor courtyard. When choosing an antenna with higher gain, what other antenna characteristic will also always change?

A. VSWR Ratio B. Fresnel Zone size C. Beamwidth D. Impedance E. Maximum input power

Correct Answer: C

Question 9

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

A. 802.1p to WMM mappings B. WMM-PS Dozing Interval C. RADIUS Server IP Address D. SNMPv3 Users E. EAP Authentication Type
