You are a wireless network administrator for a company that has installed a network that is based
on Cisco WLC and uses Aironet 1140 Series APs. The clients are using the 2.4 GHz band and
WPA TKIP for Layer 2 security. The president of the company reads a news article on the benefits
of 802.11n and wants to deploy it at the office so that the company can use data rates of up to 150
Mb/s. What should you tell the president?
A.
You need to change your Layer 2 security policy to WPA2 AES to achieve the 300 Mb/s data
rate.
B.
You need to purchase different APs because the 1140 Series supports only up to 54 Mb/s.
C.
You need to change the client Layer 2 security to WPA2 TKIP.
D.
You need to change the client Layer 2 security to open.
E.
802.1n data rates are possible only on 5 GHz.
F.
802.11n data rates are possible with the current client Layer 2 security, but for a theoretical data
rate of 300 Mb/s, you need to use channel bonding, which is not recommended on the 2.4 GHz
band.
