B. E-LAN
C. E-Line
D. E-Interworking
Correct Answer: C
Explanation/Reference:
Explanation:
Explanation:
. E-Line is based on a point-to-point Ethernet Virtual Connection. Two E-Line services are defined:
Ethernet Private Line (EPL): A very simple and basic point-to-point service characterized by low frame delay, frame delay variation, and frame loss ratio. No service multiplexing is allowed, and other than a committed information rate (CIR) no class of service (CoS) (Bandwidth Profiling) is allowed.
Ethernet Virtual Private Line (EVPL): A point-to-point service wherein service multiplexing (more than one Ethernet Virtual Connection) is allowed. The individual Ethernet Virtual Circuits can be defined with a rich set of Bandwidth Profiles and Layer 2 Control Protocol Processing methods as defined by the Metro Ethernet Forum.
