    • MEF stand for Metro Ethernet Forum.
    • According to the MEF, 5 attributes distinguish Carrier Ethernet from familiar LAN-based Ethernet.
    • The bulk of MEF-CECP Exam questions relate to MEF specifications 6.1 and 10.2.
    • MEF standards published after April 2013 are not included in the MEF-CECP 2.0 exam.
    • If a bridge receives an Ethernet frame with an unknown unicast destination address, the frame is: Flooded.
    • When a bridge learns a MAC address, that address is: The source address within a frame received by the bridge.

    • The interface between an Operator MEN (Operator CEN) and the subscriber is called a: UNI.
    • Service multiplexing allows: Multiple EVCs on one UNI.
    • The physical demarcation point between the responsibility of the Service Provider and the responsibility of the Subscriber is the MEF definition of a UNI.
    • Equipment on the subscriber side of the UNI that connects to the MEN (CEN) is called the: Customer edge.
    • EVPL and EVP-LAN Carrier Ethernet service combinations can be offered simultaneously at a given UNI. B-)
