Dynamic VLAN authorization allows edge devices to dynamically assign users to specific VLANs based on authentication results. This mechanism is widely used to guide user traffic into the correct VN in a CloudCampus virtualized campus network.

Forwired users, bothMAC address authenticationand802.1X authenticationsupport dynamic VLAN assignment. Once authentication succeeds, the authentication server delivers authorization VLAN information to the edge node, and users are placed into the corresponding VLANs. Therefore, statementsCandDare correct.

Forwireless users,802.1X authenticationalso supports dynamic VLAN authorization, making statementBcorrect. However,Portal authentication for wireless users does not support dynamic VLAN assignmentin CloudCampus networks. Wireless Portal authentication typically controls access rights rather than VLAN placement.

According to HCIP Datacom Campus Network documentation, statement A is false, making it the correct answer.

To deploy802.1X authenticationon Huawei campus switches and use aRADIUS serverfor user authentication and authorization, several core configuration components are mandatory. All four options listed are required for a complete and functional deployment.

Anauthentication domainis mandatory because it defines where user authentication requests are processed and which AAA schemes are used. Without a domain, the switch cannot determine how to handle authentication requests, makingoption A mandatory.

Anauthentication profileis also required. This profile binds authentication methods (such as 802.1X), authentication domains, and access policies together. Interfaces reference the authentication profile to determine how users are authenticated, sooption B is mandatory.

An802.1X access profiledefines detailed 802.1X parameters, such as authentication mode, reauthentication behavior, and client handling. This profile is bound to interfaces to enable 802.1X authentication on specific ports, makingoption C mandatory.

Finally, anAAA schemeis essential because it defines the authentication, authorization, and accounting methods used by the device, including RADIUS server configuration. Without an AAA scheme, the device cannot communicate with the RADIUS server or obtain user authorization information. Therefore,option D is mandatory.

According to HCIP Datacom Campus Network documentation, all four configuration steps are required to successfully enable 802.1X authentication with RADIUS-based access control.

Huawei’s free mobility solution is based onsecurity group–based policy control. In this architecture, users are dynamically associated with security groups after authentication. These security group identifiers are thencarried in user trafficas metadata when packets traverse the campus network.

When traffic reaches apolicy enforcement device, such as an edge node or border node, the device does not rely on traditional attributes like IP address, MAC address, or port number to make forwarding decisions. Instead, it extracts thesource and destination security group informationembedded in the traffic and matches it against the security policy matrix configured on the controller.

This mechanism enables identity-based and location-independent access control. Even if a user moves to a different access point or changes an IP address, the same security policies continue to apply as long as the user remains in the same security group. This is the core advantage of free mobility in Huawei campus networks.

Port numbers, MAC addresses, and IP addresses are traditional Layer 2 and Layer 3 identifiers, but they do not provide sufficient context for identity-based policy enforcement. According to HCIP Datacom Campus Network documentation, security group information is the key attribute used for policy lookup and enforcement in free mobility solutions. Therefore, option A is correct.
