    • An internal DNS server

    • Domain controller
    • Certificate server
    • DHCP server
  4. Generally speaking, what three ways can Windows 7 be configured with a VPN client?
    • A Windows 7 VPN connection
    • A Connection Manager (CM) client
    • A Third Party client
  5. For authentication on a VPN server, RRAS can be configured to forward the authentication request to a ______, or use _____ authentication.

  12. Although PPTP (Point-to-Point-Tunneling-Protocol) is the easiest VPN protocol to implement, it's major drawback when compared to other options is....

    PPTP is not as secure as other protocols as it does not ensure data integrity or data origin authentication.
  13. List the six steps in the Remote Access VPN Connectivity Process
    • 1. The VPN client contacts the VPN server
    • 2. The VPN tunnel is negotiated
    • 3. The VPN tunnel is created
    • 4. Remote access authentication is performed
    • 5. Remote access authorization is performed
    • 6. The VPN connection is established
  14. Give a brief, simple description of DirectAccess
