Networking Chapter 11 Advanced Networking DevicesVirtual Private Network (VPN) - correct answer Companies can establish direct private network links among themselves or create private, secure Internet access, in effect a "private tunnel" within the Internet endpoints - correct answer the ends of the tunnel where the data is encrypted and decrypted. VPN Tunnel - correct answer The secure connection created between user's computer and a company's network is called a(n) _____. Point-to-Point Tunneling Protocol (PPTP) - correct answer A protocol that works with PPP to provide a secure data link between computers using encryption. (Data Link Layer) Routing and Remote Access Service (RRAS) - correct answer A special remote access server program, originally only available on Windows Server, on which a PPTP endpoint is placed in Microsoft networks. VPN Connection Quality - correct answer A system connected to a VPN looks as though it's on the local network but performs much slower than if the system was connected directly back at the office because it's not local at all. host-to-site VPN - correct answer A VPN created between a host and a network across a local or intermediary network. Also known as a remote access VPNs. Layer 2 Tunneling Protocol (L2TP) - correct answer VPN technology that has quickly gaining popularity due to the inclusion of IPSec as its security protocol. Runs on almost any type of connection, including telephone lines, ethernet, and fiber. Layer 2 Forwarding (L2F) - correct answer A VPN protocol designed (by Cisco Systems) with the intent of providing a tunneling protocol for PPP. Like L2TP, L2F lacks native security features. VPN concentrator - correct answer A device that aggregates hundreds or thousands of VPN connections. client-to-site VPN - correct answer Also known as a remote-access VPN, a client-to-site VPN interconnects a remote user with a site, as an alternative to dial-up or ISDN connectivity, at a reduced cost. site-to-site VPN - correct answer Interconnects two sites, as an alternative to a leased line, at a reduced cost. host-to-host VPN - correct answer A type of VPN in which two computers create a VPN tunnel directly between them. Both computers must have the appropriate software installed, and they can't serve as a gateway to other hosts on their respective networks. SSL VPN (Secure Socket Layer VPN) - correct answer A VPN format that works with a web browser (installing a separate client is not necessary); The two most common types of SSL VPNs are SSL portal VPNs and SSL tunnel VPNs. Datagram TLS (DTLS) - correct answer optimize connections for delay-sensitive applications, such as voice and video over a VPN. Uses UDP datagrams rather than TCP segments for communication. This enhances certain types of VPN traffic. Dynamic Multipoint VPN (DMVPN) - correct answer a Cisco software solution for building multiple VPNs in an easy, dynamic, and scalable manner; enables direct VPN connections between multiple locations directly. Also employs standard security (IPsec) to make all the connections secure from unwanted prying. IPSec VPN - correct answer a secure implementation of VPN with encryption Generic Routing Encapsulation (GRE) - correct answer A tunneling protocol designed to encapsulate a wide variety of network layer packets inside IP tunneling packets; paired with IPsec for encryption. You can use GRE to make a point-to-point tunnel connection that carries all sorts of traffic over Layer 3, including multicast and IPv6 traffic.
