NEW QUESTION 66
You are configuring an access point to use channel 128. What important fact should be considered about this channels?

It is a 22 MHz channel so it will overlap with the channels above and below it

It is a 2.4 GHz frequency band 40 MHz channel, so it should not be used

It is a channel that is unsupported by most access points

It is a channel that likely requires DFS when used

NEW QUESTION 67
You are troubleshooting a problem with interference from a non-802.11 device. Given that the device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum analyzer. You want to view the signal from the interfering device over time to see the activity that is generating.
What common spectrum analyzer view should you use for this analysis?

APs

Waterfall/Spectrogram

Real-time FFT

Clients

NEW QUESTION 68
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 voice over Wi-Fi, what is an action that must be performed?

Spectrum analysis to locate and identify RF interference sources.

Frequency-band hopping analysis to detect improper RF channel implementations.

Application analysis with an active phone call on an VoWiFi handset.

Protocol analysis to discover channel use on neighboring APs.

NEW QUESTION 69
A non-802.11 device is suspected of causing interference on the WLAN. You are not certain of the location or type of device. What is the best solution for locating this non-802.11 device?

Access point spectrum analyzer

Laptop-based spectrum analyzer with an omni-directional antenna

Laptop-based spectrum analyzer with a directional antenna

Laptop-based protocol analyzer with an omni-directional antenna

NEW QUESTION 70
The IEEE 802.11-2012 standard requires VHT capable devices to be backward compatible with devices using which other 802.11 physical layer specifications (PHYs)?

OFDM

HR/DSSS

ERP-PBCC

DSSS-OFDM

NEW QUESTION 71
During a post-implementation survey, you have detected a non-802.11 wireless device transmitting in the area used by handheld 802.11g scanners. What is the most important factor in determining the impact of this non-802.11 device?

Receive sensitivity

Channel occupied

Airtime utilization

Protocols utilized

NEW QUESTION 72
As a consultant, you’ve been hired by XYZ Company to provide recommendations about client device selection, operation, and interoperability. What information should be considered to help them choose the right WLAN client devices?

802.11n OFDM is more susceptible to high-power, narrowband interference than 802.11a

In order to earn Wi-Fi Alliance certification, 802.11n clients stations are required to support both
2.4 and 5 GHz frequencies

802.11ac devices support the features of the VHT PHY only in the 5 GHz frequency band.

802.11ac is not backwardly compatible with 802.11n or 802.11a.

When HR/DSSS devices are present, VHT MCS rates are disabled for the entire BSS.

NEW QUESTION 73
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?

Performing protocol analysis with a single wireless adapter that is scanning all channels in use

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

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

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

NEW QUESTION 74
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 in their department.
What WLAN feature would allow the network administrator to accomplish this task?

RBAC

WPA2

WIPS

SNMP

NEW QUESTION 75
The center frequency of channel 1 in the 2.4 GHz band is 2.412 GHz (2412 MHz).
What is the center frequency of channel 4?

2.413 GHz

2.417 GHz

2.422 GHz

2.427 GHz

NEW QUESTION 76
A client complains of low data rates on his computer. When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11acAP. Both the client and AP are 2×2:2 devices.
What is the likely cause of the low data rate issue?

Weak signal strength

Too few spatial streams

Lack of support for 802.11n

CAT5e cabling run to the AP

NEW QUESTION 77
In a mesh BSS (MBSS), according to the 802.11-2016 standard, what device connect the mesh to an Ethernet network?

Mesh Gate

Mesh Switch

Mesh Router

Mesh Portal

NEW QUESTION 78
In an 802.11n WLAN with a heterogeneous set of associated client devices including 802.11b,
11g, and 11n, what HT protection mode will the BSS use?

Mode 0: No protection mode (Greenfield)

Mode 1: Nonmember protection mode

Mode 2: 20 MHz protection mode

Mode 3: Non-HT mixed mode

NEW QUESTION 79
The requirements for a WLAN you are installing state that it must support unidirectional delays of less than 150 ms and the signal strength at all receivers can be no lower than -67 dBm. What application is likely used that demands these requirements?

VoIP

E-Mail

FTP

RTLS

NEW QUESTION 80
In a long-distance RF link, what statement about Fade Margin is true?

A Fade Margin is unnecessary on a long-distance RF link if more than 80% of the first Fresnel zone is clear of obstructions.

The Fade Margin is a measurement of signal loss through free space and is a function of frequency and distance.

Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading.

The Fade Margin of a long-distance radio link should be equivalent to the receiver’s low noise filter gain.
