NEW QUESTION 38
In the 2.4 GHz band, what data rate are Probe Requests usually sent at from an unassociated STA?

The minimum basic rate

1 Mbps

6 Mbps

NEW QUESTION 39
In the analyzer trace shown, the TBTT is nominally 102.5 milliseconds.

Why does the Beacon transmission interval vary?

The access point must arbitrate to gain access to the RF medium in order to transmit a Beacon.

The DCF Interframe space (DIFS) is nominally 50 µs, but typically varies by as much as 10 µs, which causes delays in Beacons.

This trace shows an HT network where HR/DSSS nodes are active on the network. The access point is changing slot times from short to long as needed.

Beacon frames vary in size, and therefore some take slightly longer to send than others.

NEW QUESTION 45
As it pertains to HT L-SIG TXOP Protection, what statement is true?

Support for L-SIG TXOP Protection is indicated by HT stations in the L-SIG field of the PLCP header of HT-mixed format frames.

Support for L-SIG TXOP Protection is indicated in the HT Capabilities Info field of (re)association request frames sent by ERP, OFDM, and HT-OFDM stations.

An L-SIG TXOP protected frame exchange sequence always begins with an RTS/CTS or a CTS- to-Self.

L-SIG TXOP Protection is specified for the purpose of protecting OFDM (802.11a/g) and HT- OFDM (802.11n) transmissions from HR/DSSS stations.

NEW QUESTION 46
A client is operating in an unstable RF environment. Out of five data frames transmitted to the client it only receives four. The client sends a Block Ack to acknowledge the receipt of these four frames but due to frame corruption the Block Ack is not received by the AP. Which frames will be retransmitted’

All data frames

Both the corrupted data and Block Ack

Only the data frame which was corrupted

Only the Block Ack

NEW QUESTION 47
Which parameters accurately describe the Beacon Interval field in the Beacon frame? (Choose 2)

Value can range from 0 to 2007

4-octet length

Indicates the exact time interval between Beacon transmissions

Indicates the desired time interval between TBTTs

easured in time units of 1024 µs

NEW QUESTION 48

(Choose 2)

RSN IE

SSID

Status code

Association ID

Supported rates

NEW QUESTION 49
You are analyzing a problem with a specific client adapter.
The vendor specifications sheet does not provide detailed information.
What tool can you use to provide the most detailed specification information in many such cases?

WLAN controller

Spectrum analyzer

FCC ID Search

Wi-Fi finder

NEW QUESTION 50
WMM-PS trigger frames can be what type of IEEE 802.11 frames? (Choose 2)

QoS Null

Reassociation

QoS Data

CTS

QoS Action

PS-Poll

NEW QUESTION 51
ABC Company’s WLAN administrator is getting complaints from one user that his WLAN throughput is sluggish compared to other users in his area. The administrator takes his diagnostics laptop, which has a wireless protocol analyzer installed, to the area where the complaining user works. The administrator uses the PING utility to test connectivity from the complaining user’s wireless client station to another wireless client station across the closest access point, while capturing the wireless frames.
The administrator sees what is displayed in this screenshot.

From this screenshot, which statements can you conclude to be TRUE that are related to the complaining user’s throughput problem? (Choose 2)

The complaining user’s WLAN client utilities are configured with a small fragmentation threshold.

The complaining user’s station is retransmitting fragments many times likely due to nearby RF interference.

The access point and other stations are using ERP-OFDM modulation, and the complaining user’s wireless client station is using HR/DSSS modulation.

The complaining user’s wireless client station should be using RTS/CTS as a protection mechanism, but it is not.

The access point is not signaling for protection (Protection = no) in the Beacons, but it should be.

NEW QUESTION 52
Which one of the following is not a valid reason for an AP to fail a STAs association?

Requesting station has the wrong PSK

Does not support the specified authentication algorithm

AP is unable to handle additional associations

Requesting station does not support all the required data rates

NEW QUESTION 53
What does the value of the Listen Interval field in an Association Request frame indicate?

How long a STA performing active scanning will listen for Probe Responses before changing channels

How often a STA will go off channel to look for other BSSs

How often a STA in power save mode wakes up to listen to Beacon frames

How long a STA waits for an Ack before retransmitting the frame

NEW QUESTION 54

When operating a BS5 in the CBRS band

When operating a BSS in FIPS mode

When operating a BSS in a government facility

Only when a STA roams back to an AP it has previously been associated with

Every time a STA roams

NEW QUESTION 56

An 802.11 wireless adaptor

A firmware upgrade for the spectrum analysis adapter

A directional antenna

SNMP read credentials to the WLAN controller or APs

A supported WLAN adaptor with a customized driver

Any 802.11 wireless adaptor

A dual radio spectrum analyzer card

SNMP read credentials to the WLAN controller or APs

NEW QUESTION 58
Shown is a screenshot of a wireless protocol analyzer displaying the decode information for a single 802.11 encrypted data + CF-Poll frame. The infrastructure BSS on which this information was captured is using WEP and this particular frame was sent from a client station (STA) to an access point (AP).

As a protocol analyst, how would you explain the existence of this frame on the wireless medium given the information in the decode?

The IEEE 802.11 network is using both version 1 and version 2 protocols simultaneously. This unexpected frame is from the version 2 protocol set.

The frame was sent by a client station that does not comply with IEEE HR/DSSS standard to an access point that is Wi-Fi certified.

The access point is operating as a repeater, and clients must poll repeater access points in order to transmit data frames through them.

The frame was misinterpreted because of insufficient information received by the analyzer due to frame corruption.

NEW QUESTION 59
What is the Extended IFS used in 802.11 contention?

When the higher data rates are used and you want the fastest medium access times

When the lower data rates are used and you want the fastest medium access times

When 802.11ac must coexist with 802.11n

When a frame reception begins but the received frame is incomplete or corrupted based on the FCS
