QUESTION 30

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.

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
