An RTS frame should be acknowledged by which frame?

What is the default 802.11 authentication method for a STA when using Pre-RSNA?

Which one of the following is not a valid acknowledgement frame?

Which common feature of a Spectrum Analyzer would be the best to help you locate a non-802.11 interference source?

Which one of the following is an advantage of using display filters that is not an advantage of capture-time filters?

As a wireless network consultant you have been called in to troubleshoot a high-priority issue for one of your customers. The customer's office is based on two floors within a multi-tenant office block. On one of these floors (floor 5) users cannot connect to the wireless network. During their own testing the customer has discovered that users can connect on floor 6 but not when they move to the floor 5. This issue is affecting all users on floor 5 and having a negative effect on productivity.

To troubleshoot this issue, you perform both Spectrum and Protocol Analysis. The Spectrum Analysis shows the presence of Bluetooth signals which you have identified as coming from wireless mice. In the protocol analyzer you see the top frame on the network is Deauthentication frames. On closer investigation you see that the Deauthentication frames' source addresses match the BSSIDs of your customers APs and the destination address is FF:FF:FF:FF:FF:FF:FF.

What do you conclude from this troubleshooting exercise?

When performing protocol analysis, you capture an 802.1 lac data frame on channel 52, transmitted at MCS 8. At what data rate was the PHY Preamble transmitted?

What is used to respond with an uplink transmission to an MU-RTS trigger frame in the 802.11ax PHY?

In the 2.4 GHZ band, what data rate are Probe Requests usually sent at from an unassociated STA?

In which element of a Beacon frame would you look to identity the current HT protection mode in which an AP is operating?

Which one of the statements regarding the Frame Control field in an 802.11 MAC header is true?

Given a protocol analyzer can decrypt WPA2-PSK data packets providing the PSK and SSID are configured in the analyzer software. When performing packet capture (in a non-FT environment) which frames are required in order for PSK frame decryption to be possible?

What should the To DS and From DS flags be to set to in an Association Response frame?

In what scenario is Open Authentication without encryption not allowed based on the 802.11 standard?

Where, in a protocol analyzer, would you find an indication that a frame was transmitted as part of an A-MPDU?

What is the difference between a Data frame and a QoS-Data frame?

The PHY layer provides framing by adding a header to create what type of data unit?

Protocol analyzers may present field values in either binary, decimal or hexadecimal. What preceeds a hexadecimal value to indicate it is hexadecimal?
