What security method is commonly used for VoIP handsets when the infrastructure does not support OKC or FT roaming?
When the infrastructure does not support Opportunistic Key Caching (OKC) or Fast Transition (FT) roaming, WPA2-Personal is commonly used for VoIP handsets. This is because WPA2-Personal (also known as WPA2-PSK) does not require re-authentication with a RADIUS server, which can introduce delays that are not acceptable for the real-time communication needs of VoIP. Instead, WPA2-Personal uses a pre-shared key, which allows for faster roaming and avoids the latency issues associated with WPA2-Enterprise re-authentication.
correct answer is D. WPA2-Personal
D is the answer. With OKC, the client performs a standard 802.1X/EAP authentication on initial connection to the network. (Page 453 of CWNA-107 Study Guide). If the device doesn't support Fast Roaming, then Pre-shared Key (WPA2-PSK or WPA2-Personal) is recommended because WPA-Enterprise without Fast Roaming can introduce delay during roaming because of its requirement for full re-authentication.
Is this correct, i see the same question elsewhere with option PSK with passphrase
I mean WPA-Personal
