GSLC · Question #501
Which of the following security protocols can be used to support MS-CHAPv2 for wireless client authentication? Each correct answer represents a complete solution. Choose two.
The correct answer is B. PEAP D. PPTP. MS-CHAPv2 requires a tunneling or encapsulating protocol to carry it securely; both PEAP and PPTP provide that capability for wireless and VPN authentication respectively.

Why each option
MS-CHAPv2 requires a tunneling or encapsulating protocol to carry it securely; both PEAP and PPTP provide that capability for wireless and VPN authentication respectively.
HTTP is a web transfer protocol and has no mechanism to carry or encapsulate MS-CHAPv2 authentication exchanges.
PEAP (Protected Extensible Authentication Protocol) creates a TLS-encrypted tunnel over which MS-CHAPv2 is used as the inner authentication method, making it a standard 802.1X wireless authentication choice.
IPsec authenticates using certificates or pre-shared keys via IKE and does not natively support MS-CHAPv2.
PPTP (Point-to-Point Tunneling Protocol) natively uses MS-CHAPv2 for user authentication and directly supports MS-CHAPv2 credentials as part of its design.
