The correct answer is B.

OBJ-4.2: MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device. Public wireless networks can be configured to use MAC filtering to block access to devices once they reach a certain time limit. It appears that after 30 minutes, the restaurant’s wireless access points are adding your MAC address to the block list. If you change your MAC address through MAC spoofing, you can reconnect to the network for another 30 minutes without any issues. Since the wireless network provides the IP address, IP spoofing would not successfully allow you to reconnect since the MAC filtering would block your access before obtaining an IP. IP spoofing is a method of modifying the source address in the packet header to make the receiving computer system think the packet is from a trusted source, such as another computer on a legitimate network, and accept it. A dictionary attack is a method of breaking into a password-protected computer, network, or other IT resource by systematically entering every word in a dictionary or list file. A brute-force attack consists of an attacker submitting every possible combination for a password or pin until they crack it.
