The delivered configuration clearly indicates that aVPN instancenamedMKThas been created and bound to a VXLAN identifier. In Huawei virtualized campus networks that useVXLAN + BGP EVPN, aVN (Virtual Network)configured on iMaster NCE-Campus is typically instantiated on devices as anip vpn-instance. This VPN instance represents the logical tenant or virtual routing domain used for service isolation.

Several key lines confirm this mapping. The commandip vpn-instance MKTis the core object created for a VN. Theroute-distinguisher (RD)is configured to ensure route uniqueness for that VPN instance. The presence ofvpn-target import/export extcommunityandvpn-target … evpnshows that routes are controlled and exchanged using BGP extended communities, including EVPN-related RTs for VXLAN EVPN route import/export. This is exactly what iMaster NCE-Campus generates when a VN is created and needs to participate in EVPN route distribution.

Finally, vxlan vni 6 binds the VPN instance to a VNI, which is how VXLAN identifies and separates virtualized networks. Creating a fabric or external network would not directly generate an ip vpn-instance with RD/RTs and a VNI binding. Therefore, the administrator operation was to create a VN named MKT.

In Huawei campus network access control solutions, different authentication methods are selected based onterminal capabilities, user mobility requirements, and service scenarios. According to HCIP Datacom Campus Network documentation,Portal authenticationandMAC address authenticationare designed for distinct use cases, and the statement correctly describes their recommended application scenarios.

Portal authenticationis well suited for environments withhigh user mobility and a wide variety of terminal types, such as shopping malls, supermarkets, airports, and exhibition centers. In these scenarios, users frequently connect and disconnect from the network using mobile phones, tablets, and laptops. Portal authentication provides a flexible and user-friendly access method, typically through a web page where users enter credentials, accept terms, or obtain temporary access. It does not require pre-installed client software and supports fast onboarding of diverse devices, making it ideal for public or semi-public access networks.

On the other hand,MAC address authenticationis recommended fordumb terminalsthat lack interactive user interfaces or browser capabilities. Devices such as printers, fax machines, IP phones, and some IoT terminals cannot complete Portal authentication. MAC authentication allows the network to authenticate these devices based on their MAC addresses, enabling automatic and seamless access once the MAC address is registered in the authentication system.

Using the appropriate authentication method improves user experience, simplifies network management, and enhances security. Therefore, the statement accurately reflects Huawei’s recommended authentication practices and isTRUE.

In the Huawei CloudCampus Solution,device registrationis a key step that allows network devices such as switches, routers, and APs to establish a trusted management relationship withiMaster NCE-Campus. When a device is powered on and configured for cloud or controller-based management, it sends a registration request to the controller using a predefined service port.

According to HCIP Datacom Campus Network documentation,port 18008is used as thedestination portfor device registration requests sent to iMaster NCE-Campus. This port is specifically reserved for device onboarding and registration services, ensuring secure and standardized communication during the initial connection phase. Once the registration is successful, the controller can authenticate the device, assign it to a site, and push management and service configurations.

The other options are not correct in this context.Port 53is used for DNS services and has no role in controller registration.Port 179is used by BGP for routing protocol communication and is unrelated to device management.Port 10020is commonly associated with other management or telemetry functions but is not used for device registration in CloudCampus solutions.

Correctly configuring network connectivity and firewall rules to allow traffic to destination port18008is essential for successful zero-touch provisioning and automatic onboarding of devices. Therefore, the correct destination port number for device registration requests to iMaster NCE-Campus is18008, making optionDthe correct answer.

The displayed entries match the format of EVPN routes that carryVTEP reachability informationrather than host MAC/IP bindings or IP prefixes. The key clue is the field naming style shown asNetwork(EthTagId/IpAddrLen/OriginalIp)along with values like0:32:1.1.1.0, which indicates an IP address with a /32 length carried as the “OriginalIp”. In Huawei VXLAN BGP EVPN implementations described in HCIP Datacom Campus Network materials, this type of information corresponds toEVPN Route Type 3 (Inclusive Multicast Ethernet Tag Route).

Type 3 routes are used by VTEPs to signal membership information for a broadcast domain and to supportBUM (Broadcast, Unknown unicast, Multicast)forwarding behavior in the VXLAN fabric. Practically, they also provide the remote VTEP IP information needed so that, once the underlay can reach that VTEP IP address at Layer 3 (for example via IGP/BGP underlay routes), the local device can establish VXLAN encapsulation forwarding to that peer.

By contrast,Type 2routes would display MAC address information (and possibly a host /32 IP together with the MAC), andType 5routes would show IP prefixes like /24 or /30 used for inter-subnet routing.Type 1routes are related to Ethernet segments for multihoming (ESI), which is not what this output shows. Therefore, only statement A is true.

In VXLAN-based networks, inter-subnet communication and external network access requireLayer 3 forwarding capabilities. ALayer 3 VXLAN gatewayperforms routing between different VXLAN segments (VNIs) and enables traffic to exit the VXLAN overlay toward traditional non-VXLAN networks.

The NVE interface is responsible only for VXLAN encapsulation and decapsulation and does not perform routing. VLANIF interfaces are used in traditional VLAN environments and do not provide VXLAN interworking. A Layer 2 VXLAN gateway supports bridging only and cannot route between subnets.

Therefore, the Layer 3 VXLAN gateway is the correct solution for inter-subnet communication and external access.

In HCIP Datacom Campus Network VXLAN architecture, VXLAN tunnels are classified based onhow the tunnel endpoints are created and maintained, which is referred to as the VXLAN tunnel creation mode. According to Huawei VXLAN design principles, there aretwo valid VXLAN tunnel types: static VXLAN tunnels and dynamic VXLAN tunnels.

Astatic VXLAN tunnelis manually configured by an administrator. In this mode, the source VTEP IP address, destination VTEP IP address, and related parameters are explicitly specified on devices. Static VXLAN tunnels are typically used in small-scale networks or test environments where the number of VTEPs is limited and network topology is simple. However, static configuration lacks scalability and flexibility, making it unsuitable for large campus fabrics.

Adynamic VXLAN tunnelis automatically created based on control-plane learning mechanisms, such asBGP EVPN. In this mode, VTEPs learn remote VTEP IP addresses dynamically through EVPN route advertisements (for example, Type 3 routes). When a remote VTEP becomes reachable at the underlay Layer 3 level, the VXLAN tunnel is automatically established without manual intervention. This mode is widely used in modern campus and data center networks due to its scalability and automation capabilities.

Options A and D are incorrect becausestatelessandstatefulare not official VXLAN tunnel creation classifications in Huawei’s VXLAN implementation. VXLAN itself is an encapsulation mechanism, and tunnel state is not categorized in this manner.

Therefore, the correct VXLAN tunnel types based on creation mode arestatic VXLAN tunnels and dynamic VXLAN tunnels.

In Huawei campus network solutions,free mobilityis a user-centric access control mechanism designed to decouple network policies from physical locations and traditional network identifiers. According to HCIP Datacom Campus Network documentation, free mobility doesnotrely on VLAN IDs or IP addresses as the basis for policy management and permission control. Instead, it is implemented based onuser identity, such as user accounts, roles, user groups, or device identities.

Traditional networks often bind security policies to VLANs or IP subnets, which means users receive different permissions when they move to different access points or switch ports. This approach lacks flexibility and increases configuration complexity. Free mobility solves this problem by using centralized authentication and authorization mechanisms, such as 802.1X or MAC authentication combined with AAA, to dynamically assign policies after user authentication.

Once a user is authenticated, the network enforces access permissions based on predefined user roles or groups, regardless of where the user connects to the network. Even if the user’s IP address or VLAN changes due to roaming, the same security policy is consistently applied. This ensures seamless access experience, simplifies network management, and enhances security control.

Because free mobility isidentity-based rather than VLAN- or IP-based, the statement claiming that it implements policy management and permission control based on users' VLAN IDs and IP addresses is incorrect. Therefore, the correct answer isFALSE.

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.

In Huawei campus networks, user access authentication is implemented through a standardized AAA framework that supports flexible authentication, authorization, and accounting methods. Statements A, B, and D correctly describe the authentication configuration process defined in HCIP Datacom Campus Network documentation. Administrators must first identify user domains and corresponding AAA schemes to ensure users are authenticated using appropriate methods. This is a foundational step for implementing network access control.

Access profiles and authentication profiles work together to define how users are authenticated. An authentication profile specifies the authentication mode, such as 802.1X or MAC authentication, while the access profile defines access control behavior. Binding these profiles and applying them to interfaces or VAP profiles enables consistent enforcement of access policies across wired and wireless networks.

When external authentication servers such as RADIUS or HWTACACS are used, interconnection parameters—including server IP addresses, shared keys, and ports—must be configured within the AAA scheme. This ensures reliable communication between network devices and authentication servers.

Statement C is false becauseiMaster NCE-Campus does support interconnection with third-party RADIUS servers. This capability allows enterprises to integrate existing authentication systems with Huawei campus solutions, improving compatibility and deployment flexibility. Therefore, the incorrect statement is option C.

Huawei campus switches support multiple flexible VLAN assignment methods to meet diverse access control and service deployment requirements. The most basic method isinterface-based VLAN assignment, where a physical or logical port is statically assigned to a specific VLAN. This method is simple and widely used in traditional access layer designs.

Huawei switches also supportMAC address–based VLAN assignment, allowing devices to be dynamically placed into VLANs based on their MAC addresses. This is useful in scenarios where users frequently move between access ports but require consistent VLAN membership.

Protocol-based VLAN assignmentenables traffic to be classified into VLANs based on upper-layer protocol types, which can be useful in special service separation scenarios. Additionally,IP subnet–based VLAN assignmentallows switches to assign VLANs according to the source IP address of packets, enabling logical grouping of users based on network layer addressing rather than physical location.

These VLAN assignment mechanisms enhance network flexibility, simplify user mobility, and improve access-layer service management. According to HCIP Datacom Campus Network documentation, Huawei switches indeed support VLAN assignment based on interface, MAC address, protocol, and IP address. Therefore, the statement is TRUE, and option A is correct.
