    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.
