    多选题
    Which three statements about end-to-end delay are true？ （）
    A

    End-to-end delay is the sum of propagation delays， processing delays， serialization delays， and queuing delays.

    B

    Coast-to-coast end-to-end delay over an optical link is about 20 ms.

    C

    Processing delay depends on various factors， which include CPU speed， CPU utilization， IP switching mode， and router architecture.

    D

    Propagation and serialization delays are related to the media.

    E

    Propagation delay is the time it takes to transmit a packet and is measured in bits-per-second （bps）.

    F

    Serialization delay is the time it takes for a router to take the packet from an input interface and put it into the output queue of the output interface.

    You are the network administrator for your company. A user is complaining that they are not able to access the network with the Junos Pulse client. You run a packet capture on the network interface to monitor the 802.1X authentication process. You notice that after the EAP- request/identity packet is received, and the supplicant responds with an EAP-response/identity packet, no further communication occurs for several seconds. What are three causes for this behavior?（）
    A

    The authenticator is not licensed to support Junos Pulse.

    B

    The authenticator did not receive the EAP-response/identity packet.

    C

    The authentication server is not receiving the RADIUS packet containing the EAP-response/identity data.

    D

    The authenticator is sending the request over its loopback interface.

    E

    The authentication server is sending back a RADIUS response packet, but the authenticator is not forwarding the response back to the supplicant.
