QUESTION: 234

Which option may be used as a wireless LAN security feature?

Probe request frames
Protocol filters
Active scanning keys
ATIM windows

Answer(s): B

Explanation:

Protocol filters (IP protocol, IP port, and Ether type) prevent or allow the use of specific protocols through the bridge's Ethernet and radio ports. You can set up individual protocol filters or sets of filters. You can filter protocols for wireless client devices, users on the wired LAN, or both. For example, an SNMP filter on the bridge's radio port prevents SNMP access through the radio but does not block SNMP access from the wired LAN.
IP address and MAC address filters allow or disallow the forwarding of unicast and multicast packets either sent from or addressed to specific IP or MAC addresses. You can create a filter that passes traffic to all addresses except those you specify, or you can create a filter that blocks traffic to all addresses except those you specify.
