topology?

A
60
Q

A DMZ, also known as a perimeter network, holds devices that need to be seen by the security zones of a network. It is an example of a local area network (LAN), which is a network confined to a single building or an area of a building.

A
61
Q

IP addresses are logical addresses assigned to devices. These addresses allow
devices to communicate with each other within a network. Private IP addresses
are nonroutable addresses, meaning that data cannot be sent directly from
devices with these addresses to devices outside the network in which the
devices reside. A loopback IP address allows a device to test network
functionality.

A
62
Q

Local area networks (LANs) encompass a building or a portion of a building. They can be wired and/or wireless in nature. A special type of LAN, a virtual LAN (VLAN), is a logical LAN that allows for multiple networks to share one or more physical switches.

A
63
Q

Wide area networks (WANs) are networks that connect multiple networks in multiple locations. Many businesses transmit data from one location to another
over a WAN connection. The world’s largest WAN is the internet.

A
64
Q

Users and businesses have many choices for determining the best possible internet connection to fill the need for a solid connection. Some connections, such as leased lines and DSL, are dedicated connections. Some connections have faster bandwidth than others and some are not in large use in the current scope of internet connections

A
65
Q

Most mobile devices run on cellular networks, which offer speeds such as 4G, 3G, or 2G. These speeds vary greatly depending on a user’s cellular plan or proximity to a mobile tower.

A
66
Q

Satellite networks are prominent in areas where cable or DSL internet is not available. While faster than dial-up, satellite comes with certain limitations.

A
67
Q

Wireless networks have standards and with those standards come frequencies
and top speeds, both of which users will want to know for the exam. The key
component to understand is the compatibility among the different wireless
standards.

A
68
Q

There are two basic categories of network security for wireless networks. One involves using wireless standards and the other uses an authentication server.
Users will want to know how both types of network security work for the exam.

A
69
Q

Not all wireless connections involve a single, central wireless access point. Some connections are directly between two devices while others connect entire wired
networks with each other.

A
70
Q

The placement of a wireless access point in a home or business network can affect the speeds obtained by devices accessing the WAP. By keeping placement
in mind, users can avoid issues such as wireless interference.

A
71
Q

The placement of a wireless access point in a home or business network can affect the speeds obtained by devices accessing the WAP. By keeping placement
in mind, users can avoid issues such as wireless interference.

A
72
Q

802.11ac

A

Improves upon 802.11n by implementing wider channels (80 or 160 MHz versus 40 MHz) in the 5
GHz band, more spatial streams (up to eight versus four), higher-order modulation (up to 256-QAM
vs. 64-QAM), the addition of MU-MIMO, and yields a data rate of up to 433.3 Mbps per spatial
stream, 1300 Mbps total, in 80 MHz channels in the 5 GHz band.

73
Q

802.11a

A

Provides protocols that allow transmission and reception of data at rates of 1.5 to 54 Mbps and
operates at a frequency of 5 GHz.

74
Q

802.11b

A

Has a maximum raw data rate of 11 Mbps, uses the same media access method defined in the
original standard, and operates at a frequency of 2.4 GHz.

75
Q

802.11g

A

Operates at a maximum physical layer bit rate of 54 Mbps exclusive of forward error correction codes,
or about 22 Mbps average throughput, and operates at a frequency of 2.4 GHz. It is also fully
backwards compatible with 802.11b hardware.

76
Q

802.11n

A

Improves upon the previous 802.11 standards by adding MIMO. 802.11n operates on both the 2.4
GHz and the 5 GHz bands. Support for 5 GHz bands is optional. Its net data rate ranges from 54
Mbps to 600 Mbps.
