HOTSPOT
A company has client computers that run Windows 7. You set up a virtual private network (VPN)
infrastructure that encapsulates Point-to-Point Protocol (PPP) traffic over the Secure Sockets Layer
(SSL) channel of the HTTPS protocol.
You need to create the VPN connection on the company’s client computers. Which type of VPN should you use? (To answer, select the appropriate setting or settings in the work area.)
Answer: Secure Socket Tunneling Protocol (SSTP)
Explanation:
SSTP
Secure Socket Tunneling Protocol (SSTP) is a new tunneling protocol that uses the HTTPS protocol
over TCP port 443 to pass traffic through firewalls and Web proxies that might block PPTP and
L2TP/IPsec traffic. SSTP provides a mechanism to encapsulate PPP traffic over the Secure Sockets
Layer (SSL) channel of the HTTPS protocol. The use of PPP allows support for strong authentication
methods, such as EAP-TLS. SSL provides transport-level security with enhanced key negotiation,
encryption, and integrity checking.
