Which statements accurately describe next steps?

A customer wants to implement Virtual IP redundancy, such that in case of a ClearPass server outage, 802.1x authentications will not be interrupted. The administrator has enabled a single Virtual IP address on two ClearPass servers.

Which statements accurately describe next steps? (Select two.)
A . The NAD should be configured with the primary node IP address for RADIUS authentication on the 802.1x network.
B . A new Virtual IP address should be created for each NA
D . Both the primary and secondary nodes will respond to authentication requests sent to the Virtual IP address when the primary node is active.
E . The primary node will respond to authentication requests sent to the Virtual IP address when the primary node is active.
F . The NAD should be configured with the Virtual IP address for RADIUS authentications on the 802.1x network.

Answer: DE

Explanation:

In an Aruba network, APs are controlled by a controller. The APs tunnel all data to the controller for processing, including encryption/decryption and bridging/forwarding data. Local controller redundancy provides APs with failover to a backup controller if a controller becomes unavailable. Local controller redundancy is provided by running VRRP between a pair of controllers. The APs are then configured to connect to the “virtual-IP” configured for the VRRP instance.
