Understand the different wireless technologies.
Cell phones, Bluetooth (802.15), and 
wireless networking (802.11) are all called wireless technologies, even though they are all 
different. Be aware of their differences, strengths, and weaknesses. Understand the basics 
of securing 802.11 networking.
Understand Fibre Channel.
Fibre Channel is a form of network data storage solution (i.e., 
SAN (storage area network) or NAS (network-attached storage)) that allows for high-speed 
file transfers.
Understand FCoE.
FCoE (Fibre Channel over Ethernet) is used to encapsulate Fibre 
Channel communications over Ethernet networks.
Understand iSCSI.
iSCSI (Internet Small Computer System Interface) is a networking stor-
age standard based on IP.
Understand 802.11 and 802.11a, b, g, n, and ac.
802.11 is the IEEE standard for wireless 
network communications. Versions include 802.11 (2 Mbps), 802.11a (54 Mbps), 802.11b 
(11 Mbps), 802.11g (54 Mbps), 802.11n (600 Mbps), and 802.11ac (1.3+ Mbps). The 
802.11 standard also defines Wired Equivalent Privacy (WEP).
Understand site survey.
A 
site survey
is the process of investigating the presence, strength, 
and reach of wireless access points deployed in an environment. This task usually involves 
walking around with a portable wireless device, taking note of the wireless signal strength, 
and mapping this on a plot or schematic of the building.
Understand WPA2.
WPA2 is a new encryption scheme known as the Counter Mode with 
Cipher Block Chaining Message Authentication Code Protocol (CCMP), which is based on 
the AES encryption scheme.
Understand EAP.
EAP (Extensible Authentication Protocol) is not a specific mechanism 
of authentication; rather it is an authentication framework. Effectively, EAP allows for new 
authentication technologies to be compatible with existing wireless or point-to-point con-
nection technologies.
