When an ACK frame is not received by the transmitting STA, what is assumed?

• A.  The receiver is offline
• B.  The frame was correctly delivered
• C.  The frame was not delivered and must be retransmitted
• D.  The receiver processed the frame, but did not respond with an ACK frame because 802.11w is enabled

When antenna gain is reported in dBi, the gain of the antenna is compared to what theoretical radiator?

• A.  Dipole radiator
• B.  Anthropomorphic radiator
• C.  Isotropic radiator
• D.  End-fire radiator

What wireless networking term describes the increase of RF energy in an intentional direction with the use of an antenna?

• A.  Passive Gain
• B.  Active Amplification
• C.  Directed Radiation
• D.  Beam Digression

What facts are true regarding controllers and APs in a Split MAC architecture?

• A.  An IP tunnel is established between the AP and controller for AP management and control functions.
• B.  Management and data frame types must be processed locally by the AP, while control frame types must be sent to the controller.
• C.  With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator.
• D.  Using centralized data forwarding, APs never tag Ethernet frames with VLAN identifiers or 802.1p CoS.

Three access points are used within a facility. One access point is on channel 11 and the other two are on channel 1. The two access points using channel 1 are on either side of the access point using channel 11 and sufficiently apart so that they do not interfere with each other when they transmit frames. Assuming no other APs are in the vicinity, is CCI still a possibility in this network and why?

• A.  No, because CCI only occurs in the 5 GHz frequency band.
• B.  Yes, because channel 11 loops around and causes CCI with channel 1.
• C.  Yes, because the client devices connected to one of the channel 1 APs will transmit frames that reach the other channel 1 AP as well as clients connected to the other channel 1 AP.
• D.  No, because the APs are far enough apart that no CCI will occur.
