Which of the following is the definition of hub?

A device that connects two or more networks and selectively interchanges packets of data between them.

A network device that connects network segments, echoing all received traffic to all other ports.

A firewall device that examines the state of a connection as well as simple address, port, and protocol rules to determine how to process a packet.

A suite of protocols designed to connect sites securely using IP networks.

________ is a suite of protocols designed to connect sites securely using IP networks.

Dynamic Host Configuration Protocol (DHCP)

Network access control (NAC)

Point-to-Point Tunneling Protocol (PPTP)

Internet Protocol Security (IPSec)

________ allows the computer to get its configuration information from the network instead of the network administrator providing the configuration information to the computer. It provides a computer with an IP address, subnet mask, and other essential communication information, simplifying the network administrator’s job.

Internet Protocol Security (IPSec)

Dynamic Host Configuration Protocol (DHCP)

Point-to-Point Tunneling Protocol (PPTP)

Internet Control Message Protocol (ICMP)

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

Hub

Firewall

Router

Switch

What term is used to describe a method of IP address assignment that uses an alternate, public IP address to hide a system’s real IP address?

Application proxy firewall

Network address translation (NAT)

Internet Control Message Protocol (ICMP)

Network access control (NAC)

A _____________ contains rules that define the types of traffic that can come and go through a network.

Firewall

Hub

Switch

Network protocol

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 ________.

Stateful inspection firewall

Packet-filtering firewall

Application proxy firewall

Point-to-Point Tunneling Protocol (PPTP)

Which of the following is the definition of packet-filtering firewall?

An advanced firewall that processes all traffic between two systems. Instead of allowing a direct connection between two systems, it connects to each system separately and passes filtered traffic to the destination based on filtering rules.

A firewall device that has three NICs. One NIC connects to the Internet, the second connects to the internal network, and the third connects to a DMZ.

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

A protocol used on IP networks to provide configuration details automatically to client computers.

What name is given to a protocol to implement a VPN connection between two computers?

Dynamic Host Configuration Protocol (DHCP)

Internet Control Message Protocol (ICMP)

Screened subnet

Point-to-Point Tunneling Protocol (PPTP)

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

Wireless access point (WAP)

Wi-Fi Protected Access (WPA)

Screened subnet

Wired Equivalent Privacy (WEP)

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

A management protocol for IP networks.

A protocol to implement a VPN connection between two computers.

A method to restrict access to a network based on identity or other rules.

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