NEW QUESTION 85
AP-1 is a 3×3:2 AP. STA-3 is a 3×3:3 client. What is the maximum number of spatial streams that can be used for a downlink HT-OFDM transmission from AP-1 to STA-3?

One spatial stream, because the definition of the AP indicates that it is capable of only one spatial stream.

Three spatial streams, because the definition of the client indicates that it is capable of only three spatial streams.

Two spatial streams, because the definition of the AP indicates that it is capable of only two spatial streams.

Three spatial streams, because the definition of the AP indicates that it is capable of only three spatial streams.

NEW QUESTION 86
You support a WLAN using dual- band 802.11ac three stream access points. All access points have both the 2.4 GHz and 5 GHz radios enabled and use 40 MHz channels in 2.4 GHz. A manager is concerned about the fact that each access point is connected using a 1 Gbps Ethernet link. He is concerned that the Ethernet link will not be able to handle the load from the wireless radios. What do you tell him?

His concern is valid and the company should upgrade all Ethernet link to 10 Gbps immediately.

His concern is valid and the company should immediately plan to run a second 1 Gbps Ethernet link to each AP.

Due to 802.11 network operations and dynamic rates used by devices on the network, the two radios will likely not exceed the 1 Gbps Ethernet link .

His concern is invalid because the AP will compress all data before transmitting it onto the Ethernet link.

NEW QUESTION 87
XYZ Company has decided to install an 802.11 WLAN system that will support 1000 wireless users, but they are concerned about network security. XYZ is interested in deploying standardized security features. In addition to WPA2-Enterprise with PEAP and role-based access control, XYZ would like to support management frame protection as well as a fast secure roaming protocol for future mobile handsets.
As XYZ Company selects a product to deploy, what two IEEE amendments, which are included in
802.11- 2016, should be supported to provide the management frame protection and fast secure roaming security features?

802.11j and 802.11k

802.11r and 802.11k

802.11z and 802.11w

802.11r and 802.11w

NEW QUESTION 88
What advantages does using predictive site survey modeling software offer over performing a manual site survey? (Choose 2)

Predictive modeling software can predict the ideal access point location 100% of the time, whereas the results from manual surveyingare less reliable.

Predictive modeling software makes it simple to assess multiple different AP locations and then adjust and display the AP’s expected coverage pattern in almost real-time.

Predictive modeling software provides more reliable data than manual surveys when fine-tuning and validating access point placement after the installation.

The exact impact of interference sources from external networks can be more accurately measured when using predictive modeling software than with manual surveys.

It takes less time to create an initial site survey for a large facility when using predictive modeling software than when performing a manual survey.

NEW QUESTION 89
What statement about the beamwidth of an RF antenna is true?

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

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

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

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

NEW QUESTION 90
An 802.11-based network uses an AP and has several connecting clients. The clients include iPhones, iPads, laptops and one desktop. What WLAN use case is represented?

Ad-hoc

WPAN

BSS

IBSS

NEW QUESTION 91
Lynne runs a small hotel, and as a value added service for her customers she has implemented a Wi-Fi hot-spot. Lynne has read news articles about how hackers wait at hot- spots trying to take advantage of unsuspecting users. She wants to avoid this problem at her hotel.
What is an efficient and practical step that Lynne can take to decrease the likelihood of active attacks on her customers’ wireless computers?

Implement Network Access Control (NAC) and require antivirus and firewall software along with OS patches.

Require EAP-FAST authentication and provide customers with a username/password on their receipt.

Implement an SSL VPN in the WLAN controller that initiates after HTTPS login.

Enable station-to-station traffic blocking by the access points in the hotel.

NEW QUESTION 92
You are implementing a VHT-capable AP. Which one of the following channels is available in the 802.11-2016 standard that was not available before the ratification of 802.11 ac?

161

153

144

NEW QUESTION 93
Which one of the following channels can be used for VHT transmissions?

NEW QUESTION 94
What factors does not influence the distance at which an RF signal can be effectively received?

Free Space Path Loss

Receiving station’s radio sensitivity

Transmitting station’s output power

Receiving station’s output power

NEW QUESTION 95
Which of the following frequency ranges are specified for use by IEEE 802.11 radios? (Choose all that apply.)

902 – 928 MHz

2.4000 – 2.4835 GHz

5.15 – 5.25 GHz

5.470 – 5.725 GHz

5.725 – 5.875 GHz

NEW QUESTION 96
In which plane of the three networking planes is an access point configured by a WLAN controlled?

Control

Management

Security

Data

NEW QUESTION 97
In a Wi-Fi client configuration utility, what feature is most likely to be user configurable?

802.1p to WMM mappings

SNMPv3 Users

WMM-PS Dozing Interval

RADIUS Server IP Address

EAP Authentication Type

NEW QUESTION 98
What statement about the IEEE 802.11-2016 QoS facility is true?

802.11 control frames are assigned to the 802.11 EF priority queue.

When the Voice queue has frames awaiting transmission, no data will be transmitted from the Best Effort queue.

802.11 QoS is achieved by giving high priority queues a statistical advantage at winning contention.

Four 802.1p user priorities are mapped to eight 802.11 transmit queues.

NEW QUESTION 99
An 802.11-based network uses an AP and has several connecting clients. The clients include iPhones, iPads, laptops and one desktop. What WLAN use case is represented?

Ad-hoc

WPAN

BSS

IBSS
