The company has just upgraded their access layer switches with AOS-CX switches and implemented an AAA solution with ClearPass. The company has become concerned about what actually connects to the user ports on the access layer switch, Therefore, the company is implementing 802.1X authentication on the AOS-
CX switches. An administrator has globally enabled 802.1X, and has enabled it on all the access ports connected to user devices, including VoIP phones, security cameras, and wireless Aruba IAPs. Wireless users are complaining that they successfully authenticate to the IAPs; however, they do not have access to network resources.

What should the company do to solve this problem? Implement device-based mode on the IAP-connected AOS-CX switch ports. Implement local user roles and local forwarding on the AOS-CX switches. Implement downloadable user roles and user-based tunneling (UBT) on the AOS-CX switches. Implement AAA RADIUS change of authorization on the AOS-CX switches.

Which ClearPass feature should the administrator leverage to help determine that MAC address spoofing is not occurring for this group of devices? User-based tunneling Device fingerprinting RADIUS change of authorization Downloadable user roles.
A network administrator sets up two aggregation layer AOS-CX switches in a VSX pair. The switches have layer-2 VSX LAGS to access layer switches. The VSX pair has IGMP configured on the layer-3 VLAN interfaces serving the access layer switches.

Forwarding and pruning of multicast traffic is based on a shared IGMP group database Join and leave messages are always forwarded across the ISL link between the VSX aggregate switches If one of the VSX switches reboots, the IGMP group database is automatically synchronized between the two switches.
Examine Route r4's partial OSPF configuration:

mtu 9000
ip ospf heilo-interval 1
ip ospf dead-interval 4
ip ospf authentication simple-text
ip ospf authentication-key key 123
When executing the "show ip ospf neighbors" command, Router 4 is in a FULL state with Router 3 and Router 2, but a 2-WAY state with Routed.
What is causing the 2-WAY state with Router 1?
