A network administrator is implementing NAE on AOS-CX switches. When attempting to create an agent on a particular switch, the agent appears in the NAE Agents panel with a red triangle error symbol and a status of
"Unknown".
What is the cause of this issue?

• A.The administrator does not have the appropriate credentials to interact with NAE.
• B.The number of scripts or agents has exceeded the hardware's capabilities.
• C.A connectivity issue exists between NAE and the AOS-CX switch
• D.The RESTful API has not been enabled on the AOS-CX switch.

An administrator is replacing the current access switches with AOS-CX switches. The access layer switches must authenticate user and networking devices connecting to them. Some devices support no form of authentication, and some support 802.1X. Some ports have a VoIP phone and a PC connected to the same port, where the PC is connected to the data port of the phone and the phone's LAN port is connected to the switch.
Which statement is correct about this situation?

• A.Device fingerprinting is required for authentication
• B.802.1X must be configured to work in fallback mode
• C.Device mode should be implemented
• D.The client-limit setting for port access needs to be changed

An AOS-CX switch is configured to implement downloadable user roles. Examine the AOS-CX switch output:

Based on this output, what is the state of the user's access?

• A.The RADIUS request timed out to the AAA server
• B.No downloadable user role exists
• C.MAC authentication has passed, but 802.1X authentication is in progress
• D.The port should be configured for 802.1X

Examine the VSX-related configuration of the core layer AOS-CX switch:

A network administrator is troubleshooting a connectivity issue involving the VSX LAG (link aggregation) between the core and access layer switch, during HW replacement of one of the core switches.
Which configuration should the administrator add to the core switch to fix this issue?

• A.ICX-Tx-Core1(config)# interface 1/1/45
  ICX-Tx-Core1(config-if-vlan)# active-gateway ip 192.168.0.0 mac 02:02:00:00:01:00
• B.ICX-Tx-Core1(config)# interface lag 1 multi-chassis
  ICX-Tx-Core1(config-if-lag-if)# mtu 9198
• C.ICX-Tx-Core1(config)# vsx
  ICX-Tx-Core1(config-vsx)# system-mac 02:01:00:00:01:00
• D.ICX-Tx-Core1(config)# interface 1/1/46-1/1/47
  ICX-Tx-Core1(config-if-vlan)# active-gateway ip 10.1.11.1 mac 02:02:00:00:01:00

What is correct regarding the operation of VSX and multicasting with PIM-SM routing configured?

• A.Each VSX peers runs PIM and builds its own group database. One of the VSX peers is elected as the designated router (DR) to forward multicast streams to a receiver VLAN
• B.Each VSX peers runs PIM and builds its own group database. Both VSX peers can forward multicast streams to receivers in a VLAN, achieving load sharing
• C.Each VSX peers runs PIM and creates a shared group database. One of the VSX peers is elected as the designated router (DR) to forward multicast streams to a receiver VLAN
• D.Each VSX peers runs PIM and creates a shared group database. Both VSX peers can forward multicast streams to receivers in a VLAN, achieving load sharing
