Detailed explanation-1: -An administrator needs to secure a wireless network and restrict access based on the hardware address of the device. Which of the following solutions should be implemented? A security administrator must implement a firewall rule to allow remote employees to VPN onto the company network.
Detailed explanation-2: -MAC address filtering allows you to block traffic coming from certain known machines or devices. The router uses the MAC address of a computer or device on the network to identify it and block or permit the access. Traffic coming in from a specified MAC address will be filtered depending upon the policy.
Detailed explanation-3: -Wireless access points or routers allow you to configure MAC filter control lists. Such a control list specifies the addresses that are allowed to connect to the network. Anyone using a wireless network adapter that does not match the list of allowed MAC addresses will be denied access.
Detailed explanation-4: -MAC address filtering restricts access to the wireless network to hosts that have specific MAC addresses. This can be done in two different ways: +Use a whitelist, which defines a list of MAC addresses that are allowed to connect. +Use a blacklist, which defines a list of MAC addresses that are not allowed to connect.
