Jack has been monitoring his network using a specialized application. In spite of using a secure SSID password, unauthentic users are gaining access to his WiFi network without his consent. John wants specific users to be able to connect to his wireless network. What should he do?
  1. Enable MAC filtering
  2. Disable SSID broadcast
  3. Set beacon interval values to as low as possible
  4. Set beacon interval values to as high as possible
Explanation
Answer: A - Enable MAC ID filtering to ensure that any unknown MAC IDs are restricted from gaining access to the network.

Key Takeaway: Most wireless access points contain some type of MAC ID filtering that allows the administrator only to permit access to computers that have wireless functionalities containing certain MAC IDs. To set up MAC address filtering, you must configure a list of clients that will be allowed to join the network. You need to obtain the MAC addresses of each client from its operating system or configuration utility and then designate those addresses as authorized in the wireless access point or router.
