Question #1
When a data frame is encrypted with WPA2, to which portion of the frame is the encryption applied?
Please select an optionIncorrectCorrect answer: B
CCMP protects the MSDU, which comprises the LLC header and its payload, so the LLC is included in the encrypted portion. The MAC header must stay readable for addressing and is therefore excluded.
Was this answer correct?Question #2
What is the function of 802.11 Management frames?
Please select an optionIncorrectCorrect answer: A
Management frames establish and maintain membership in the basic service set, covering beacons, probes, authentication and association. Data flow, configuration pushes and traffic prioritization are handled by other frame types or mechanisms.
Was this answer correct?Question #3
Where would you look in a packet trace file to identify the configured Minimum Basic Rate (MBR) of a BSS?
Please select an optionIncorrectCorrect answer: A
Basic rates are the rates flagged as mandatory within the Supported Rates and Extended Supported Rates elements of the beacon; the lowest of those is the MBR. No MBR element or action frame exists.
Was this answer correct?Question #4
Which one of the these is the most important in the WLAN troubleshooting methodology among those listed?
Please select an optionIncorrectCorrect answer: C
Directly observing and reproducing the problem gives objective evidence, while user and manager accounts are subjective and vendor debug knowledge only helps after the symptom is known.
Was this answer correct?Question #5
What is the function of the PMD sub-layer?
Please select an optionIncorrectCorrect answer: A
The PMD is the lowest PHY sub-layer and handles modulation and transmission, turning the bits handed down by the PLCP into RF signals on the medium.
Was this answer correct?Question #6
How does a VoIP Phone, using WMM Power Save, request data frames buffered at the AP?
Please select an optionIncorrectCorrect answer: B
WMM Power Save (U-APSD) uses trigger frames: any QoS data frame from the phone in a delivery-enabled access category prompts the AP to release its buffered frames. PS-Poll belongs to legacy power save.
Was this answer correct?Question #7
What does the value of the Listen Interval field in an Association request frame indicate?
Please select an optionIncorrectCorrect answer: C
how often a STA in power save mode wakes to listen to Beacon management frames.
Was this answer correct?Question #8
Which one of the following is not a valid reason for an AP to fail a STAs association?
Please select an optionIncorrectCorrect answer: A
Association happens before the 4-way handshake, so the AP has no way to know the PSK is wrong at that point; unsupported authentication algorithm, capacity limits and missing required rates all produce a failed association status.
Was this answer correct?Question #9
Where, in a protocol analyzer, would you find an indication that a frame was transmitted as part of an AMPDU?
Please select an optionIncorrectCorrect answer: B
Was this answer correct?Question #10
When performing protocol analysis, you capture an 802.11ac data frame on channel 52, transmitted at MSC 8. At what data rate was the PHY Preamble transmitted?
Please select an optionIncorrectCorrect answer: B
The transmitter sends the preamble at 1 Mbps (802.11 or 802.11b DSSS) or 6 Mbps (802.11a or 802.11g ERP-OFDM).
