Question 1
You have captured 802.11 traffic using an adapter that includes the radio tap header. You see several frames often called announcement frames in the capture.
What best describes these types of frames?
A. They only include beacon and probe response frames
B. They are used to allow a STA to awake from sleep and for no other reason
C. They only include beacon and probe request frames
D. They are meant to provide information to the network that may result in state changes, but they are not open for rejection
Question 2
Given: Adjacent Channel Interference (ACI) can cause frame corruption and poor performance in WLANs. You are using a protocol analyzer in the attempt to detect ACI.
What should you look for in such a scenario?
A. Look at Retry counts
B. Capture on the channel you think may be impacted by ACI and see if any frames are captured from adjacent channels
C. Look for frames with a low signal strength value in the radio tap header
D. Look at CRC errors
Question 3
You are concerned with management overhead in your WLAN. When evaluating the network, you note that each dual-band AP provides for 4 SSIDs in each band with three secure SSIDs and one Open System SSID. The network runs only 802.11ac APs and uses
20 MHz channels in 2.4 GHz and 400 MHz channels in 5 GHz.
What can you do to reduce the impact of beacon frames on CCI and channel utilization?
A. Use only 40 MHz channels
B. Use the same security across all SSIDs
C. Increase the beacon interval
D. Disable SSID broadcasting
Question 4
You want to simplify viewing frames of a particular type in Wireshark.
What is used to specify frames for colorization?
A. Custom code must be written and the binaries recompiled
B. Filters are used to define the frames that should be colorized
C. A scripting language is available to modify the code before recompilation
D. Automated protocol analysis is used and no additional options may be specified
Question 5
You have been asked to recommend a protocol analysis solution that uses open source software and works with the Linux platform. It must provide decoding of 802.11ac frames and minimal support for reporting and statistics.
What solution would you recommend?
A. Wireshark
B. OmniPeek
C. Wi-Fi Analyzer Pro
D. CommView for Wi-Fi
