B : The Internet of Things is a system in which any object, natural or manmade, has its own IP address and is able to send and receive information over a network (i.e., the Internet) without human interaction. The adoption of the IPv6 created a vast number of IP addresses that allows a unique identify for every object on earth. C : The Internet of Things is a system in which any object, natural or manmade, has its own IP address and is able to send and receive information over a network (i.e., the Internet) without human interaction. The adoption of the IPv6 created a vast number of IP addresses, but there are still not enough to uniquely identify every object on the earth. D : The Internet of Things is a system in which any specially tagged inventory item has its own IP address and is able to send and receive information over a network (i.e., the Internet) without human interaction. The adoption of the IPv6 made it possible to create unique IP addresses for each inventory item.

Remote applications are widely used to allow consumers to locate stores and track packages, but advertising that is targeted based on location is not yet widely used. Such applications do allow advertisers to suggest stores, restaurants, and other services based on a user's location. D : The advertising executive is incorrect. Remote applications are widely used to allow consumers to locate stores and track packages, but advertising that is targeted based on locations is widely used. Such applications allow advertisers to suggest stores, restaurants, and other services based on a user's location.

Q 8.29: You are the manager of a coffee shop that provides free Internet access to its customers using a public hotspot. The coffee shop owner has read about evil twin attacks and asked you to post signs reminding customers that the information they share over your business's Internet connection might not be private. Is your boss justified in asking you to do this? A : Yes. The primary threat to a user's information in a public hotspot is war driving, when an attacker locates WLANs while driving (or walking) around a city or elsewhere. B : No. Information traveling over public hotspots is encrypted so that it is protected from evil twin attacks and other threats to a user's information. C : No. In evil twin attacks, the attacker uses a hotspotter to simulate a wireless access point with the same wireless network name, or SSID, as the one that authorized users expect. These types of attacks are common in corporate settings but rare in public hotspots. D : Yes. In one kind of evil twin attack, the attacker simply captures wireless transmissions. These attacks are more effective with public hotspots than with corporate networks.
