A network protocol governs how networking equipment interacts to deliver data across the network.

True

The OSI Reference Model is a theoretical model of networking with interchangeable layers.

True

The Physical Layer must translate the binary ones and zeros of computer language into the language of the transport medium.

True

The term network access control (NAC) describes a method to restrict access to a network based on identity or other rules.

True

What term is used to describe the current encryption standard for wireless networks?

Wi-Fi Protected Access (WPA)

A ___________ controls the flow of traffic by preventing unauthorized network traffic from entering or leaving a particular portion of the network.

firewall

A method to restrict access to a network based on identity or other rules is the definition of ________.

network access control (NAC)

A firewall that examines each packet it receives and compares the packet to a list of rules configured by the network administrator is the definition of ________.

packet-filtering firewall

Network ________ is gathering information about a network for use in a future attack.

reconnaissance

Which of the following is the definition of network address translation (NAT)?

A method of IP address assignment that uses an alternate, public IP address to hide a systemís real IP address.

Which OSI Reference Model layer includes all programs on a computer that interact with the network?

Application Layer

Which OSI Reference Model layer is responsible for transmitting information on computers connected to the same local area network (LAN)?

Data Link Layer

________ allows the computer to get its configuration information from the network instead of the network administrator providing the configuration information to the computer.
