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? (Choose three.)

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.
