A users Junos Pulse client uses 802.1X to access a wired network and is failing to authenticate. You run a packet capture from the users PC and notice that immediately after the client machine sends an EAPoL-start packet, an EAP-failure packet is returned. You review the RADIUS troubleshooting logs on the MAG Series device and do not see any authentication attempts from the user. Other users on the same Ethernet switch are successfully authenticating. Which device is sending the EAP-failure packet to the workstation?()A、The RADIUS serverB、The EAPoL serverC、The workstation's network adapterD、The Ethernet switch

多选题When implementing WLAN security, what are three benefits of using the Temporal Key Integrity Protocol (TKIP) instead of WEP? ()ATKIP uses an advanced encryption scheme based on AESBTKIP provides authentication and integrity checking using Cipher Block Chaining Message Authentication Code (CBC-MAC)CTKIP provides per-packet keyingand a rekeying mechanismDTKIP provides message integrity checkETKIP reduces WEP’s vulnerabilities byusing different hardware encryption chipsetFTKIP uses a 48 bit InitializationVector

多选题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? ()AThe authenticator is not licensed to support Junos Pulse.BThe authenticator did not receive the EAP-response/identity packet.CThe authentication server is not receiving the RADIUS packet containing the EAP-response/identity data.DThe authenticator is sending the request over its loopback interface.EThe authentication server is sending back a RADIUS response packet, but the authenticator is not forwarding the response back to the supplicant.
