  1. MAC address, manufacturer hardware, and SSID filtering
  2. Protocol, SSID, and WEP filtering
  3. SSID, MAC address, and Protocol filtering
  4. WEP, 802.11 standard, and manufacturer hardware filtering
Explanation
Answer - C - The three types of filtering that can be performed on a wireless LAN are SSID, MAC address, and Protocol filtering.

Key Takeaway: SSID filtering should be done to segment the network. SSID filtering does not present any real level of security. MAC filters are effective for home and small office wireless LANs where managing lists of MAC addresses is feasible. Protocol filters should be used as a means of bandwidth control.
