What information can the Agile Controller deliver to the NAS device for permission control? (Multiple choice)

Question

Options

• AVLANs
• BACLs
• CStatic ARP binding relationship
• DStatic routing
• ESome Specific RADIUSM Properties

• A
  75% (40)
• C
  17% (9)
• D
  8% (4)

Explanation

In Huawei's Agile Controller (also known as the policy controller in campus networks), the controller communicates with NAS (Network Access Server) devices via RADIUS to enforce access policies. After authenticating a user, the Agile Controller can push VLANs (A) to segment network traffic, ACLs (B) to filter which resources a user can reach, and RADIUS attributes (E) - proprietary or standard RADIUS VSAs (Vendor-Specific Attributes) that carry policy metadata like bandwidth limits or user groups.

C (Static ARP binding) is incorrect because ARP bindings are configured locally on the switch/router for IP-MAC security and are not delivered dynamically by a policy controller via RADIUS. D (Static routing) is incorrect because routing table entries are managed by the routing protocol stack or local configuration, not pushed to a NAS device by an authentication controller.

Memory tip: Think "VAR" - VLAN, ACL, RADIUS attributes - these are the three policy "levers" a controller can pull over a RADIUS channel. ARP and routing belong to the device's own local plane, not to controller-delivered authorization.
