　　2.An 802.11b telephone is receiving an audio signal from an access point, but cannot send audio. What is a possible cause?

　　A: The RSSI value on the telephone is greater than 35.

　　B: The access point is set to receive only at 802.11g data rates.

　　C: The security settings in the telephone do not match the settings in the access point.

　　D: The transmit power in the telephone is significantly lower than the transmit power in the access point.

　　Correct Answers:　D

　　3.Refer to the exhibit. Switches A and C are running PVST+ STP, and Switch B is running 802.1Q STP. If the BPDU of the root in VLAN 1 is better than the BPDU of the root in VLAN 2, then there is no blocking port in the VLAN 2 topology. The BPDU of VLAN 2 never makes a "full circle" around the topology; it is replaced by the VLAN 1 BPDU on the B-C link, because B runs only one STP merged with VLAN 1 STP of PVST+. Thus, there is a forwarding loop. What does PVST+ do to correct this?
