Question 3

Correct Answer:

Verified

One of EAP's advantages is its flexibility.It is supported by nearly all modern operating systems and can be used with any authentication method.For example,although the typical network authentication involves a user ID and password,EAP also works with biorecognition methods,such as retina or hand scanning.EAP is also adaptable to new technology.Therefore,no matter what future wireless encryption schemes are developed,EAP will support them.

A ____ firewall is a router (or a computer installed with software that enables it to act as a router)that examines the header of every packet of data it receives to determine whether that type of packet is authorized to continue to its destination.
