What happens when an 802.11a node broadcasts within the range of an 802.11g access point?
A . The access point transmits, but the node is unable to receive.
B . A connection occurs.
C . Both the node and the access point are unable to transmit.
D . The node transmits, but the access point is unable to receive.
Answer: D
Explanation:
Because 802.11a and 802.11b utilize different frequencies, the two technologies are incompatible with each other. A huge problem with 802.11a is that it’s not directly compatible with 802.11b or 802.11g networks. In other words, a user equipped with an 802.11b or 802.11g radio card will not be able to interface directly to an 802.11a access point.
