You are tasked with describing the various frames used in 802.11 communications.
What frame is used for spectrum management, fast BSS transition and some other actions taken within a BSA?

• A.PS Poll
• B.CTS
• C.BlockAck
• D.Action

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.Look at CRC errors
• C.Capture on the channel you think may be impacted by ACI and see if any frames are captured from adjacent channels
• D.Look for frames with a low signal strength value in the radio tap header

You must report on frame types seen on the WLAN. You want to list the frame types by both name and binary value.
What frame type is represented by the binary value 011010, which includes the Type and
Subtype values?

• A.Authentication
• B.Beacon
• C.PS-Poll
• D.Association Request

A new firmware has been released for the AP model you use in your WLAN. You have more than 120 of these APs installed.
What is a good reason for applying a firmware update on an enterprise AP?

• A.Enable 4x4:4 spatial streams on a 3x3:3 AP
• B.Enable the short guard interval
• C.Disable lower data rates
• D.Enable new security features and patch vulnerabilities

You have been asked to recommend a solution for protocol capture of 802.11 frames consisting of 3x3:3 802.11ac communications. The requirement specifies that you gain a general view of a coverage area and does not require that you capture from specific user locations. The solution must be the least expensive practical solution possible that does not disrupt user access to the WLAN and it must be based on enterprise WLAN hardware.
What solution would you recommend so that any coverage area could be monitored on demand?

• A.Install laptop-based protocol analyzer near each AP
• B.Install sufficient Aps so that an AP can be taken offline to perform protocol analysis as needed
• C.Install the minimum number of Aps required for coverage and use these Aps for protocol analysis as needed
• D.Install Wireshark on the Aps natively to allow dynamic capture while serving clients
