Jane, a security administrator, needs to implement a secure wireless authentication method
that uses a remote RADIUS server for authentication. Which of the following is an
authentication method Jane should use?
A.
WPA2-PSK
B.
WEP-PSK
C.
CCMP
D.
LEAP
Why is the answer D – LEAP? I think it should be A – WPA2-PSK. Can you please explain why?
Because PSK (Pre-Shared Key) is a local authentication by the WAP. They want a remote RADIUS server to do the authentication.
Protected EAP (PEAP) is supported by RADIUS.
Sorry, I meant LEAP, a Cisco proprietary method, is supported by RADIUS
Because I’m awesome!!
WPA-PSK does not use Radius, WPA2-Enterprise does and LEAP is the protocol to access the Radius server.
A & B are wrong because they use Pre Shared Key (PSK). This means that they will authenticate with a key that was pre established on both devices. The question is asking to authenticate with a remote RADIUS server. C is also wrong because CCMP/AES is used for encryption. That leaves D for the win!!
Are these questions on the exam or just practice questions? Can someone verify who has taken it within last month, please?
LEAP uses dynamic Wired Equivalent Privacy (WEP) keys that are changed with more frequent authentications between a client and a RADIUS server. WEP keys are less likely to be cracked — and less long-lived if cracked — due to this frequency.
