A customer has completed the installation of an 802.11ac greenfield deployment at their corporate headquarters. They would like to leverage 802.11ac enhanced speeds on the trusted employee WLAN. In order to configure the employee WLAN, what Layer 2 security policies are valid?
A. WPA2 (TKIP)
B. WPA(AES)
C. OPEN
D. WEP
The answer is correct! 802.11ac is only supported with open authentication or with WPA2 and AES.
WPA2 with TKIP and WPA with AES are not supported
I think the emphasis here is about enhanced speed. With WPA (AES) it will slow it down due to the process it takes to encrypt and decrypt. So, though open is not suitable in real life, it is the fastest to meet the question’s intention.
Shouldn’t this be WPA (AES) ? because it is valid and provides enterprise level security. Open is not at all suitable for a trusted employee WLAN.
