As a network Administrator, you have recently deployed a new wireless VoIP network. You have provisioned a separate SSID for the VoIP phones with 802.1X/PEAP authentication and enabled
802.11r FT for fast roaming. Your VoIP phones also support FT roaming and you have made sure it is enabled in the device profile. What type of 802.11 Authentication would you expect the VoIP phones to perform first when connecting to the network?

문제7
Using a portable analyzer you perform a packet capture next to a client STA and you can see that the STA is associated to a BSS. You observe the STA sending packets to the AP and the AP sending packets to the STA. Less than 2% of all packets are retransmissions. You move to capture packets by the AP and, while the retry rate is still less than 2%, you now only see unidirectional traffic from the AP to the client. How do you explain this behavior?

A client is operating in an unstable RF environment. Out of five data frames transmitted to the client it only receives four. The client sends a Block Ack to acknowledge the receipt of these four frames but due to frame corruption the Block Ack is not received by the AP. Which frames will be retransmitted?
