The Huawei CloudCampus Solution adopts afour-layer architecture, not a three-layer one. According to HCIP Datacom Campus Network documentation, the architecture consists of theterminal layer,network layer,management and control layer, andapplication layer.

Theterminal layerincludes user devices such as PCs, mobile terminals, IoT devices, and other endpoints that access the campus network. Thenetwork layeris responsible for data forwarding and includes access, aggregation, and core network devices. Themanagement and control layer, represented by platforms such as iMaster NCE-Campus, provides centralized management, automation, policy control, and orchestration. Theapplication layerdelivers value-added services and business applications.

Because the terminal layer is an essential and explicitly defined component of the CloudCampus architecture, stating that the solution has only three layers is incorrect. Therefore, the statement isFALSE, making optionBthe correct answer.

1 →dh group1

2 →main

3 →esp

4 →tunnel

In the IKE proposal, the Diffie-Hellman group defines the key exchange strength used during IKE Phase 1 negotiation, which is whydh group1corresponds to position 1 under the IKE proposal configuration. Theexchange-mode mainsetting is part of IKEv1 Phase 1 and therefore correctly matches position 2 under the IKE peer configuration.

For the IPsec proposal, thetransformspecifies the protocol used to protect data traffic; since ESP is explicitly required,espcorrectly maps to position 3. Finally, theencapsulation-mode tunneldefines how packets are encapsulated in IPsec VPNs between gateways, makingtunnelthe correct match for position 4.

This mapping strictly follows HCIP Datacom Campus Network IPsec and IKE configuration logic and aligns with standard Huawei VRP command behavior.

In HCIP Datacom Campus Network security design,port securityis used to limit the number of MAC addresses that can be learned on an access interface, preventing unauthorized device access and MAC address spoofing. When the number of learned MAC addresses reaches the configured upper limit, the switch behavior depends on the configuredviolation mode.

One possible action isshutdown mode, where the switch sets the interface to an error-down state and generates an alarm. This corresponds to option A. The interface must be manually or automatically recovered before normal communication can resume. This mode provides the highest level of security and clear fault notification.

Another supported behavior isprotect mode, in which the switch silently discards packets from unknown source MAC addresses after the limit is reached. No alarms are generated in this case, which matches option C. This mode minimizes network disruption while still blocking unauthorized devices.

Therestrict modeis also supported. In this mode, the switch discards packets with unknown source MAC addresses and generates an alarm or log entry, corresponding to option D. This allows administrators to detect violations without shutting down the interface.

Option B is incorrect because when an interface enters the error-down state due to a port security violation, an alarm or log notification is always generated according to HCIP Datacom Campus Network behavior. Therefore, the valid actions are A, C, and D.

In a VXLAN BGP EVPN architecture,EVPN Type 5 routes, also known asIP Prefix routes, are used to advertiseLayer 3 reachability informationbetween VXLAN segments. These routes are essential for implementing inter-VNI communication and external network connectivity through distributed or centralized gateways.

According to HCIP Datacom Campus Network documentation, a Type 5 route carriesIP prefix information, including theIP prefix and its prefix length, allowing VTEPs to learn network-level routing information rather than host-level details. TheRoute Distinguisher (RD)is also included to ensure uniqueness of routes across different VPN instances, which is critical in multi-tenant environments. Additionally, thegateway IP addressis carried to identify the next-hop gateway responsible for forwarding traffic toward the advertised prefix.

Unlike EVPN Type 2 routes, which advertiseMAC address and optional host IP address information, Type 5 routes donotcarry MAC addresses. Type 5 routes operate purely at the Layer 3 level and are independent of Layer 2 forwarding. Their purpose is to exchange subnet-level routing information rather than endpoint-level details.

MAC addresses are only relevant for Layer 2 forwarding and ARP/ND suppression, which are functions of EVPN Type 2 routes. Including MAC information in Type 5 routes would be unnecessary and inefficient for Layer 3 routing purposes.

Therefore, the field that isnot carriedin a BGP EVPN Type 5 route is theMAC Address, making optionCthe correct answer.

Super VLAN is a Huawei campus network technology designed to solve broadcast domain and user isolation issues in large Layer 2 networks. It allows multiplesub-VLANsto be associated with a singleSuper VLAN, where the Super VLAN provides Layer 3 gateway services, and sub-VLANs remain Layer 2 isolated from each other. Users within different sub-VLANs cannot communicate directly at Layer 2, which effectively isolates users even though they share the same logical gateway.

This architecture significantly enhances user communication security by preventing direct Layer 2 attacks such as ARP spoofing or broadcast storms between users. In addition, broadcast packets generated within one sub-VLAN are confined to that sub-VLAN and do not propagate to others, preventing invalid or excessive broadcast traffic from impacting overall service quality.

Port isolation only isolates ports but does not provide centralized Layer 3 gateway management. IPSG focuses on IP address legitimacy enforcement rather than user isolation. Ethernet port security restricts MAC address access but does not control broadcast propagation or inter-user isolation across VLANs.

According to HCIP Datacom Campus Network design guidelines, Super VLAN is the correct technology for isolating users in the same VLAN scope while reducing broadcast impact and improving security, making option A correct.

iMaster NCE-Campus supports multiple deployment modes to meet the needs of different enterprise customers, including on-premise deployment, MSP-owned cloud deployment, and Huawei public cloud deployment. The choice of deployment mode mainly depends on whether the customer wants to invest in infrastructure, manage the platform independently, or use a fully hosted service.

In this scenario, the supermarket chain explicitlydoes not want to purchase physical servers or software, which means an on-premise deployment is not suitable. On-premise mode requires customers to prepare hardware resources, install software, and maintain the system themselves. Similarly, an MSP-owned cloud deployment typically involves a managed service provider hosting the platform, which may still require contractual dependency on a third party and is not the most straightforward option for enterprises seeking minimal investment and simplified operations.

According to HCIP Datacom Campus Network documentation, theHuawei public cloud deploymentis recommended for customers who want acloud-based, subscription-oriented solution. In this mode, iMaster NCE-Campus is hosted and operated on Huawei Cloud. Customers only need to register and subscribe to the service, without purchasing servers, storage, or management software. Huawei is responsible for system maintenance, upgrades, security, and high availability.

This deployment model is especially suitable forretail chains and multi-branch enterprises, such as supermarkets, because it enables centralized management of geographically distributed branch networks with low initial investment and fast rollout.

Therefore, the recommended deployment mode in this case isHuawei public cloud, making optionCthe correct answer.

In iMaster NCE-Campus, device management functions are tightly integrated with secure remote access mechanisms to ensure safe and efficient O&M operations. One such mechanism is theSSH proxy tunnel, which allows administrators to remotely access managed devices through the controller without directly exposing device management interfaces to the external network.

According to HCIP Datacom Campus Network documentation, theSSH proxy tunnel is automatically established when the Command Line function is usedon the Device Management page. When an administrator clicks theCommand Lineoption, iMaster NCE-Campus dynamically builds a secure SSH proxy channel between the controller and the target device. This enables real-time CLI access to the device through the web interface while maintaining strict security controls.

Other functions such asSummary,Entry Query, andDevice Configurationdo not require direct CLI interaction with the device. These functions rely on management protocols and configuration delivery mechanisms such as NETCONF or telemetry, and therefore do not trigger the establishment of an SSH proxy tunnel.

The Command Line function is specifically designed for scenarios such as advanced troubleshooting, manual verification, or executing device-level commands. Automatically enabling the SSH proxy tunnel at this moment ensures that CLI access is bothsecure and on-demand, reducing attack surfaces and simplifying remote maintenance.

Therefore, the function that automatically enables the SSH proxy tunnel isCommand Line, making optionDthe correct answer.

In the Huawei CloudCampus Solution, access points can operate in different modes depending on network size, architecture, and management requirements. For asmall- or medium-sized campus networkwhere asingle AP is used as the network egressand must becentrally managed by iMaster NCE-Campus, the recommended operating mode isCloud mode.

When an AP works inCloud mode, it establishes a direct management connection with iMaster NCE-Campus through the cloud. The AP can independently provide wireless access services while also performing gateway and egress functions, such as user traffic forwarding and policy enforcement. This eliminates the need to deploy a dedicated wireless AC or additional gateway devices, significantly simplifying network architecture and reducing deployment cost.

Fit modeAPs rely on a local or centralized AC for control and therefore cannot independently function as a network egress.RU modeis used only in Agile Distributed Wi-Fi scenarios and depends on a central AP, making it unsuitable for this scenario.Fat modeAPs can operate independently but lack deep integration with iMaster NCE-Campus for cloud-based centralized management and automated service provisioning.

HCIP Datacom Campus Network documentation highlights Cloud APs as the optimal choice for small and medium campuses that require simplified deployment, cloud-based management, and integrated gateway capabilities. Therefore, to meet both the management and egress requirements described, the AP should operate inCloud mode.

Hence, the correct answer isC.

In the Huawei CloudCampus Solution, devices such as switches and APs support multipleprovisioning modesto integrate with iMaster NCE-Campus, including Web interface provisioning, CLI-based provisioning, and registration center query. These methods allow devices to obtain controller information and register successfully.

Firewalls, however, have stricter provisioning mechanisms due to security considerations. They do not supportDHCP Option 148, which is commonly used by switches and APs to automatically discover the management controller.

Instead, firewalls must be provisioned manually through the Web interface or CLI, or discovered via registration center mechanisms. According to HCIP Datacom Campus Network documentation,DHCP Option 148 is not supported by firewalls, makingoption Cthe correct answer.

In astatic VXLAN tunneldeployment, Huawei devices use anNVE (Network Virtualization Edge) interfaceas the logical tunnel interface for VXLAN encapsulation and decapsulation. The NVE interface represents the VTEP and does not have a one-to-one relationship with Bridge Domains (BDs) or VXLAN tunnels.

AnNVE interface can be associated with multiple VNIs, each corresponding to a different BD. Therefore, when multiple BDs exist on a VTEP,only one NVE interface is required, makingstatement B correctandstatement A incorrect.

In static VXLAN, thedestination VTEP addressesare specified usingingress replication listsunder each VNI. This allows a single NVE interface to establishmultiple VXLAN tunnelsto different remote VTEPs. As a result, there is no requirement to create a separate NVE interface for each tunnel, makingstatement D correctandstatement C incorrect.

According to HCIP Datacom Campus Network VXLAN configuration principles, the correct practice is to createone NVE interface per VTEP, associate multiple VNIs with it, and define remote peers through ingress replication. Therefore, the correct answers areB and D.

Huawei iMaster NCE-Campus supports advanced networking solutions tailored for industry-specific scenarios, including thefinancial SD-WAN SRv6 solution. This solution leverages Segment Routing over IPv6 (SRv6) to enable precise traffic steering, deterministic forwarding, and end-to-end service scheduling across the network.

Because SRv6 introduces enhanced forwarding capabilities and control-plane features beyond standard campus networking functions, Huawei licenses these capabilities separately. To activate SRv6-based financial SD-WAN features on iMaster NCE-Campus, customers must obtain theSRv6 function package license. Without this license, SRv6-specific orchestration, scheduling, and optimization functions cannot be enabled.

According to HCIP Datacom Campus Network documentation, licensing ensures controlled feature activation and aligns with Huawei’s modular service enablement strategy. Therefore, the statement is TRUE, and option A is correct.

In the Huawei Agile Distributed Wi-Fi Solution, the wireless architecture is designed to simplify deployment and reduce dependency on traditional centralized WLAN controllers. The solution is composed mainly of a **central AP** and multiple **Remote Units (RUs)**. The central AP integrates key control and management functions that are traditionally provided by a standalone AC. These functions include RU discovery and registration, radio parameter configuration, SSID and security policy delivery, traffic control, and basic WLAN service management.

Because the central AP performs these AC-like roles, RUs do not need to be managed individually, and a separate wireless controller is not required for the Agile Distributed Wi-Fi system to operate. This architecture is especially suitable for indoor distributed scenarios such as hotels, dormitories, hospitals, and office buildings, where RUs are deployed in rooms or corridors and centralized control is still required.

From the HCIP Datacom Campus Network perspective, this design reduces network complexity, lowers deployment and maintenance costs, and improves scalability. While an external AC or centralized management platform may still be introduced for unified management across multiple sites or for advanced O&M requirements, it is **not mandatory** for the basic Agile Distributed Wi-Fi solution. Therefore, the statement that no AC is needed because the central AP can manage multiple RUs is correct according to HCIP Datacom Campus Network documentation.

In a virtualized campus network built with iMaster NCE-Campus,virtual networks (VNs)are designed to belogically isolated by default. This isolation is achieved through VXLAN and VPN instances, ensuring that users in different VNs cannot communicate unless explicit interconnection mechanisms are configured. While thepolicy control matrixis an important component of access control, it isnot sufficient by itselfto implement mutual access between users in different VNs.

According to HCIP Datacom Campus Network documentation, the policy control matrix is used to defineinter-group or inter-user access permissions, typically based onsecurity groups. It controls whether traffic is permitted, denied, or restricted between different user groups. However, the policy control matrix only definessecurity policy behaviorand does not establish Layer 3 connectivity between isolated virtual networks.

To enable mutual access between users in different VNs, the administrator must also configureinter-VN connectivity mechanisms, such asexternal networks,border nodes, orroute import and export policies. This includes enabling route exchange between VPN instances using BGP EVPN and configuring appropriate gateway or routing paths. Only after Layer 3 reachability is established can the policy control matrix take effect to permit or restrict traffic.

Therefore, deploying a policy control matrix alone does not meet the technical requirements for inter-VN communication. Bothconnectivity configuration and policy controlare required. Hence, the statement is incorrect, and the correct answer isFALSE.

HuaweiCloudEngine S series switchesare designed for modern campus access scenarios that require flexible device deployment, especially for wireless APs, IP phones, cameras, and IoT terminals. According to HCIP Datacom Campus Network documentation, these switches supportPoE long-distance power supply, allowing power and data to be transmitted overCat5e Ethernet cables for distances of up to 200 metersunder specific conditions.

Traditionally, standard Ethernet transmission and PoE delivery are limited to 100 meters. However, Huawei CloudEngine S series switches introducePoE Long Distance (PoE LD) mode, which extends the maximum transmission distance while maintaining stable power delivery and communication. This capability is particularly valuable in campus environments such as schools, hospitals, warehouses, and outdoor corridors, where powered devices may be located far from access switches.

When PoE long-distance mode is enabled, the switch optimizes signal transmission and power output to ensure reliable operation over extended cabling. This reduces the need for additional intermediate switches or power supplies, simplifying network architecture and lowering deployment and maintenance costs.

It is important to note that this feature applies to supported CloudEngine S models and compliant powered devices, and appropriate cable quality such as Cat5e is required. Within these design constraints, CloudEngine S series switches are fully capable of delivering PoE over distances up to 200 meters.

Therefore, the statement is correct, and the answer isTRUE.

DHCP is a core protocol used in campus networks to automatically assign IP addresses and deliver network parameters to hosts, improving deployment efficiency and simplifying address management. DHCP messages include several fixed fields and anOptions field, which plays a critical role in parameter delivery.

Option A isfalse. Even if only gateway and DNS server information needs to be delivered to a client, the DHCP Offer messagemust carry the Options field. Default gateway and DNS server information are delivered through specific DHCP options, such as Option 3 (Router) and Option 6 (DNS Server). Without the Options field, these parameters cannot be conveyed to the client.

Option B is correct. The Options field in DHCP messages uses aTLV (Type-Length-Value)format, allowing flexible extension and supporting various network parameters, including NTP server addresses, wireless AC addresses, and log server addresses, which aligns with HCIP Datacom Campus Network descriptions.

Option C is also correct. DHCP supportsstatic IP address allocationby binding a specific IP address to a client’s MAC address. This is commonly used for printers, servers, or network devices that require fixed IP addresses.

Option D is correct as well. Because DHCP uses broadcast messages that cannot cross Layer 3 boundaries, aDHCP relay agentis required when the client and server reside on different IP networks.

Therefore, option A is the only incorrect statement.

In Huawei campus networks, access authentication and authorization are implemented based on the AAA framework. After a user is successfully authenticated, the network enforces anauthorization result, which defines what network resources the user is allowed to access and how traffic is controlled. These authorization results are typically delivered by the authentication server or configured locally on network devices.

According to HCIP Datacom Campus Network documentation,authorization results focus on policy and access control attributes, not basic network parameter assignment. Common authorization items includeVLAN assignment,security group assignment, andACL application. VLANs determine the user’s logical network location, security groups enable group-based policy control, and ACLs restrict or permit traffic based on predefined rules. These elements directly affect access permissions and security enforcement.

AnIP address, however, does not need to be defined in the authorization result. In campus networks, IP addresses are usually assigned dynamically throughDHCP, either by a DHCP server or a DHCP relay function on network devices. The IP address allocation process is independent of user authorization and does not represent an access control policy.

Separating IP address assignment from authorization simplifies network design and improves scalability. It allows users to obtain IP addresses automatically while access rights are enforced consistently through identity-based policies. Therefore, among the given options,IP addressis not an item that must be defined in the authorization result.

Hence, the correct answer isB.

In large- and medium-sized Huawei campus network admission designs, it is common forPCs to be connected downstream of IP phones. In such scenarios, both the IP phone and the PC share the same physical access port on the switch, but they have different authentication and service requirements.

To support this deployment model, Huawei recommendsmulti-mode authentication. Multi-mode authentication allowsmultiple authentication methods to coexist on the same interface. Typically, the IP phone usesMAC address authenticationto quickly obtain voice service access, while the connected PC uses802.1X authenticationto obtain data network access. This ensures that voice and data services are securely and independently authenticated without requiring additional ports.

Portal authentication is mainly used for web-based access and is not suitable for chained device scenarios. Pure 802.1X or MAC authentication alone cannot meet the requirement because they do not support differentiated authentication for multiple terminals behind a single interface.

According to HCIP Datacom Campus Network admission control guidelines, multi-mode authentication is the correct solution for PCs connected to IP phones, making option A correct.

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.

Port isolation is commonly used on access switches to preventwired terminalsfrom communicating directly with each other at Layer 2. This enhances security by blocking lateral attacks and unnecessary broadcast traffic.

Forwireless users, Huawei APs and WLAN controllers (or central APs in agile distributed scenarios) providewireless user isolationmechanisms. Wireless user isolation prevents clients connected to the same SSID or AP from directly communicating with each other, even though they share the same wireless medium. This is widely used in guest networks, dormitories, and public WLAN environments.

Therefore, the statement that APs cannot implement wireless user isolation is incorrect. According to HCIP Datacom Campus Network WLAN design principles,wireless user isolation is fully supported by APs, either locally or under centralized control.

Hence, the statement is FALSE, and option B is correct.

Explanation (Based on HCIP Datacom Campus Network Design)

Position 1 → 802.1X AuthenticationThis authentication point corresponds to aPC connected to an access switch. PCs typically support 802.1X clients, making802.1X authenticationthe preferred and most secure method for wired user access. It provides strong identity-based access control using a RADIUS server.

Position 2 → Portal AuthenticationThis point representswireless user access. Portal authentication is commonly used for wireless terminals, especially guest or mobile users, where browser-based authentication is required. Users authenticate through a web page redirected by the access device.

Position 3 → MAC Address AuthenticationThis point corresponds tonon-802.1X-capable terminals, such as IP phones or printers. These devices cannot initiate 802.1X or Portal authentication, soMAC address authenticationis used to identify and authenticate them based on their MAC addresses.

This authentication deployment aligns with Huawei NAC best practices:

802.1X for capable wired terminals

Portal for wireless or guest access

MAC authentication for dumb or IoT devices

In VXLAN BGP EVPN, different EVPN route types carry different kinds of reachability information. The displayed entries areIP prefix routesbecause each record shows anIP prefix and prefix length(for example, 172.16.2.0:24 and 192.168.122.0:30) rather than a MAC address with a host /32. In HCIP Datacom Campus Network VXLAN EVPN, such network-segment routes are advertised usingEVPN Route Type 5 (IP Prefix Route). Type 5 routes are used to distributeLayer 3 reachabilitybetween VTEPs for inter-subnet/inter-VRF routing, and they inherently carrynetwork/mask information, which makes statement D correct.

These routes are associated with theL3 VXLAN forwarding plane, meaning they belong to theL3VNI(the VPN instance/VRF context). L3VNI is used for routing between IP subnets in an EVPN VXLAN fabric, while L2VNI is used for pure Layer 2 bridging within a broadcast domain. Because the entries shown are IP prefixes (not MAC learning information), they align withL3VNI-based routing, so statement B is correct and statement A is incorrect.

Statement C is incorrect becauseType 2routes are MAC/IP Advertisement routes typically used for host reachability (often /32) and include MAC information, which is not present in these entries.

In a CloudCampus virtualized campus network,Virtual Networks (VNs)provide service isolation, whilesecurity groupsenable identity-based access control. Even when inter-VN routing is technically available, communication between users in different VNs isnot permitted by default. Access permissions are controlled bysecurity group–based policies.

To allowR&D personnel and sales personnelto communicate, the network administrator must explicitly define thesecurity policy relationshipbetween the two security groups. This is achieved by deploying apolicy control matrixon iMaster NCE-Campus. The policy control matrix specifies whether traffic between source and destination security groups is allowed or denied and enforces the policy on relevant network devices.

Deploying an external network is unnecessary because communication is required within the campus network. Configuring access management relates to authentication and authorization during network access, not inter-group communication control. Configuring inter-VN communication enables routing capability but does not definewhethercommunication is permitted at the security policy level.

According to HCIP Datacom Campus Network documentation,security group communication permissions are controlled through the policy control matrix, making optionAthe correct task to meet the requirement.

Huawei’s free mobility solution is designed to provide consistent user access control and policy enforcement across the campus network, regardless of user location. According to HCIP Datacom Campus Network documentation, the solution is built around severalclearly defined core roles, each with specific responsibilities.

Theauthentication deviceis a core role. It performs user authentication using methods such as 802.1X, MAC authentication, or portal authentication, and associates user identity information with IP addresses or security groups.

Thepolicy enforcement deviceis also a core role. It enforces security and access control policies based on IP-security group information, ensuring that traffic complies with defined policies wherever the user is connected.

iMaster NCE-Campusis another core component of the free mobility solution. It acts as the centralized management and control platform, responsible for policy definition, IP-security group management, and coordination of information distribution between authentication points and policy enforcement points.

Thepolicy control device, however, isnot a core roleexplicitly defined in Huawei’s free mobility architecture. Policy control functions are integrated into iMaster NCE-Campus rather than implemented as a separate standalone device role. Therefore, “policy control device” is not recognized as a core role in the free mobility solution.

As a result, option B is the correct answer, while the other options represent essential components of Huawei’s free mobility solution as defined in HCIP Datacom Campus Network materials.

In a VXLAN-based virtualized campus network, theunderlay networkis responsible for providing basic IP connectivity between VXLAN Tunnel Endpoints (VTEPs). Statement D correctly describes this fundamental role of the underlay. Statement C is also correct, as VXLAN usesMAC-in-UDP encapsulationto overlay Layer 2 networks on top of a traditional IP infrastructure.

When iMaster NCE-Campus is used for automatic orchestration of the underlay routing domain,multiple routing protocols can be supported, depending on the solution version and design. Therefore, statementA is false, because OSPF is not the only supported routing protocol.

Statement B is correct in the context of standard automated deployment: iMaster NCE-Campus supportsOSPF single-area deploymentfor simplified orchestration and maintenance of the underlay network.

According to HCIP Datacom Campus Network architecture principles, the underlay must be stable, simple, and highly available, but it is not limited to a single routing protocol. Thus,option Ais the incorrect statement and the correct answer.

In Huawei CloudCampus wireless solutions for small- and medium-sized campus networks,refined traffic controlmeans the ability to precisely limit and manage bandwidth consumption at theindividual user level. Among the available rate limiting modes,user-based rate limitingis specifically designed to meet this requirement.

User-based rate limiting applies bandwidth control policiesper authenticated user, regardless of which SSID, AP, or radio the user is connected to. This allows administrators to ensure fair bandwidth allocation, prevent a single user from monopolizing wireless resources, and provide differentiated service levels for different user roles, such as employees, guests, or VIP users. This fine-grained control aligns with identity-based access and policy management promoted in HCIP Datacom Campus Network design.

In contrast,SSID-based rate limitingcontrols bandwidth at the service level. It limits total traffic for an entire SSID, which affects all users connected to that SSID collectively, rather than individually.Radio-based rate limitingcontrols bandwidth per radio interface, focusing on wireless resource optimization instead of user-level fairness.ACL-based rate limitingis mainly used for traffic classification and control in wired or advanced scenarios and is not suitable for per-user refined wireless traffic control in CloudCampus WLAN deployments.

Therefore, when the requirement is refined traffic control foreach individual wireless user,user-based rate limitingis the most appropriate and effective option. Hence, the correct answer isA.

Position 1 → Before authenticationBefore users are authenticated, they are placed in thepre-authentication domain. At this stage, access is strictly limited to basic network services such as theAdmission server,DHCP server, andDNS server. This allows users to obtain IP addresses and reach authentication-related services only.

Position 2 → Upon authentication failuresIf user authentication fails or security posture checks (such as antivirus or patch verification) do not pass, users are redirected to theisolation domain. In this domain, access is restricted to remediation resources likevirus signature database serversandpatch servers, preventing users from accessing business services while allowing problem resolution.

Position 3 → After successful authenticationAfter authentication succeeds, users enter thepost-authentication domain. At this stage, full or role-based access is granted to enterprise resources such asoffice data,R&D data,marketing systems, as well asintranet or Internet services, based on assigned policies.

This mapping reflects Huawei’s standardNAC domain-based access control model, ensuring secure, staged network access.

iMaster NCE-CampusInsight is anintelligent O&M analysis componentin Huawei’s CloudCampus Solution, designed to provide deep visibility, experience assurance, and fault diagnosis based onreal service traffic and user behavior. The statement is incorrect because CampusInsight doesnot rely on SNMP technologyto achieve its core capabilities.

According to HCIP Datacom Campus Network documentation, traditional SNMP is mainly used for basic device monitoring, such as interface status, CPU usage, memory usage, and simple alarms. SNMP focuses ondevice-level metricsand does not provide sufficient granularity to analyze application performance, user experience, or end-to-end service paths.

In contrast, iMaster NCE-CampusInsight usestelemetry, traffic sampling, flow analysis, and packet-level inspection technologiesto collect real-time and fine-grained data directly from network devices. These technologies allow CampusInsight to analyzeactual service traffic, identify application behavior, locate faults across the network path, and proactively detect network exceptions that affect user experience.

CampusInsight correlates data such as flow information, latency, packet loss, and service reachability to perform intelligent analysis and root cause identification. This enables capabilities like application experience assurance, abnormal traffic detection, and proactive fault prediction, which are beyond the scope of SNMP-based monitoring.

Therefore, because iMaster NCE-CampusInsight does not use SNMP as its primary data collection method and instead relies on advanced telemetry and traffic analysis technologies, the statement isFALSE.

In Huawei’s free mobility solution based on iMaster NCE-Campus, the method used for obtaining IP-security group entries depends on whether the device acts as an authentication point, a policy enforcement point, or both. When a devicefunctions as both an authentication point and a policy enforcement point, it can directly obtain user identity information during the authentication process.

According to HCIP Datacom Campus Network documentation, when authentication occurs on a device, that device locally learns user identity attributes such as IP address, security group, and access policy. In this scenario, the device doesnot need to subscribeto IP-security group entries from iMaster NCE-Campus in order to view or use user information. iMaster NCE-Campus proactively delivers relevant policy and security group information to the device as part of centralized control and coordination.

IP-security group entrysubscriptionis required only when the policy enforcement point isnotthe authentication point. In that case, the enforcement device must subscribe to IP-security group entries or receive them from the authentication device to correctly enforce policies.

Because the device in this scenario performs both authentication and enforcement roles, user information is directly available without subscription. Therefore, the statement claiming that administrators must subscribe to IP-security group entries to view user information is incorrect.

Hence, the correct answer isFALSE, which aligns with Huawei free mobility operational principles defined in HCIP Datacom Campus Network materials.

In a CloudCampus VXLAN fabric,node role planningis a fundamental design task that directly affects scalability, performance, and manageability. Huawei defines clear roles for fabric nodes, includingedge nodes,border nodes, and optionallyroute reflectors (RRs).

Statements A, B, and C correctly describe recommended design practices. Core devices are commonly deployed asborder nodesbecause they have higher performance and are well suited to connect the VXLAN fabric to external networks such as WANs or data centers. Access or aggregation devices acting asedge nodesenable end-to-end VXLAN automation and allow user traffic to be encapsulated and decapsulated close to the access layer. Additionally, when external networks exist in different physical locations, deployingmultiple border nodesimproves reliability and optimizes traffic paths.

Statement D is incorrect. In a VXLAN network usingBGP EVPN with route reflectors,edge nodes do not need to establish BGP peer relationships with each other. Instead, edge nodes establish BGP EVPN peer relationshipsonly with the RR, which centrally reflects EVPN routes to other nodes. This design significantly reduces the number of BGP sessions and improves scalability in large networks. Border nodes may also peer with the RR, but full-mesh peering between edge nodes is not required.

Therefore, the false statement isD, making it the correct answer.

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.

Administrator:

– Defining a Security Group

– Defining a Policy Control Matrix

iMaster NCE-Campus:

– Delivering IP-Group Entries

– Delivering a Policy Control Matrix

In Huawei’s free mobility solution, responsibilities are clearly divided betweenadministratorsandiMaster NCE-Campusto achieve centralized control with automated policy delivery. Administrators are responsible forpolicy and security intent definition, while iMaster NCE-Campus handlesautomatic distribution and enforcement coordination.

Administrators firstdefine security groups, which represent logical user or terminal categories such as employees, guests, or IoT devices. These security groups form the basis of identity-based access control in the campus network. Administrators alsodefine the policy control matrix, which specifies communication permissions between different security groups, such as allow, deny, or redirect. This step represents business intent and security requirements and must be manually planned and configured.

Once these definitions are complete,iMaster NCE-Campus takes over the execution phase. It automaticallydelivers the policy control matrixto authentication points and policy enforcement points, translating high-level policies into device-level configurations. This ensures consistent policy enforcement across the entire campus network.

In addition, iMaster NCE-Campus automaticallydelivers IP-group entries, which bind user IP addresses to security groups. These entries are dynamically generated based on authentication results and are distributed to relevant devices so that traffic can be correctly identified and controlled as users move.

This division of labor aligns with HCIP Datacom Campus Network design principles, enabling simplified administration, reduced manual configuration, and truly seamless free mobility across the campus network.
