Suggested Answer: CD 🗳️
Ethernet private line (EPL) and Ethernet virtual private line (EVPL) are carrier Ethernet data services defined by the Metro Ethernet Forum. EPL provides a point- to-point Ethernet virtual connection (EVC) between a pair of dedicated usernetwork interfaces (UNIs), with a high degree of transparency. EVPL provides a point- to-point or point-to-multipoint connection between a pair of UNIs.
The services are categorized as an E-Line service type, with an expectation of low frame delay, frame delay variation and frame loss ratio. EPL is implemented using a point-to-point (EVC) with no Service Multiplexing at each UNI (physical interface), i.e., all service frames at the UNI are mapped to a single EVC (a.k.a. all- to-one bundling).
