WAN connectivity Chapter 13 Flashcards
Which VPN technology enables direct connection between satellite locations?
Dynamic Multi Point VPN (DMVPN)
Define Dynamic Multi Point VPN (DMVPN)
A virtual private network solution optimized for connections between multiple locations directly.
Define Passive Optical Network (PON)
A fiber architecture that uses a single fiber to the neighborhood switch and then individual fiber runs to each final destination.
Define Wide Area Network (WAN)
A geographically dispersed network created by linking various computers and LANs over long distances, generally using least phone lines. No firm dividing line between LAN and a WAN
Define Multi Protocol Label Switching (MPLS)
Router feature that labels certain data to use a desired connection. Works with any type of packet switching (even ethernet) to force certain types of data to use a certain path.
Define Digital Subscriber Line (DSL)
Highspeed internet connection technology that uses regular telephone line for connectivity. DSL comes in several varieties including asymmetric (ADDSL) and symmetric (SDSL) and many speeds. Typical home user connections are ADSL with download speed of up to 9Mbps and an upload 1Kbps.
Define Data over cable service interface specification (DOCSIS)
standard protocol used by cable modem networks to facilitate data transfer
Define Point to point tunneling protocol (PPTP)
legacy protocol intended to provide a secure datalink between computers (VPN) long been included in windows, fallen out of favor because security issues
Define Layer 2 Tunneling Protocol (L2TP)
VPN protocol developed using CISCO L2F and Microsoft PPTP tunneling protocols that can be run on almost any connection imaginable. L2TP has no authentication or encryption, but is often used with ipsec to provide security
Define Secure Socket Layer VPN (SSL VPN)
Type of VPN that formally used SSL encryption but now uses TLS. The two most common types are SSL Portal VPNS and SSL Tunnel VPNS. Portal VPNS clients connect to the VPN server using a standard web browser. Tunnel VPNs, they use a dedicated VPN client. Despite the fact that SSL is no longer in use the SSL VPN moniker stuck.
Define Datagram TLS (DDLS VPN)
VPN solution that optimizes connections for delayed sensitive applications, such as voice and video. Uses TLS to provide encryption for enhanced security.
