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.

IKEv1 negotiation consists of two phases.Phase 1is responsible for establishing a secure IKE Security Association (SA), including peer authentication, key exchange, and protection of subsequent negotiations. In Huawei IPsec implementations, IKEv1 Phase 1 supportsMain modeandAggressive mode.

Main modeuses six message exchanges to securely negotiate parameters, protect identity information, and establish a trusted channel. It provides higher security and is commonly used in site-to-site IPsec VPN scenarios.Aggressive mode, on the other hand, completes negotiation using only three message exchanges, offering faster setup at the cost of reduced identity protection.

Quick modeis not part of IKEv1 Phase 1; it is used inPhase 2to negotiate IPsec SAs for data traffic protection.Normal modeis not a valid IKEv1 negotiation mode.

According to HCIP Datacom Campus Network documentation and standard IPsec principles, the supported IKEv1 Phase 1 negotiation modes areMain mode and Aggressive mode, makingoptions B and Ccorrect.

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.

Explanation (Concise and Technical)

Position 1 → 100This corresponds toVNI 100, which is associated with BD10 and is used for communication between PC1 and PC3.

Position 2 → 3.3.3.3This is theremote VTEP IP addressof VTEP3, configured as a head-end peer for VNI 100 on VTEP1.

Position 3 → 200This representsVNI 200, which is bound to BD20 and enables VXLAN communication between PC2 and PC4.

Position 4 → 1.1.1.1This is theremote VTEP IP addressof VTEP1, configured as a head-end peer for VNI 200 on VTEP2.

This mapping follows standardstatic VXLAN tunnel configuration logicon Huawei devices, where each VNI is explicitly associated with remote VTEP peer addresses using head-end peer-list.

BGP EVPN is an extension of the BGP protocol designed to support large-scale Layer 2 and Layer 3 virtualization, such as VXLAN-based campus and data center networks. To achieve this, BGP EVPN defines multipleEVPN route typesthrough BGP extensions, including MAC/IP Advertisement routes, Inclusive Multicast routes, Ethernet Segment routes, and IP Prefix routes. Therefore, statement A is correct.

In BGP EVPN, routing information is carried using theMP_REACH_NLRI (Multiprotocol Reachable Network Layer Reachability Information)attribute. EVPN-specific NLRI formats are encapsulated within MP_REACH_NLRI, making statement C correct.

Each EVPN route includes aRoute Distinguisher (RD), which is part of the EVPN NLRI itself. The RD is used to ensure route uniqueness across different EVPN instances. Since the EVPN NLRI is carried inside MP_REACH_NLRI, the RD is effectively carried through MP_REACH_NLRI as well, which makes statement B correct.

Statement D is incorrect.Route Targets (RTs)are not carried in MP_REACH_NLRI. Instead, RTs are transmitted usingBGP extended community attributes, which control route import and export policies between EVPN instances. RTs are used for VPN membership control, not for route reachability advertisement.

In summary, BGP EVPN relies on BGP extensions and MP_REACH_NLRI to transport EVPN routing information and RDs, while RTs are carried separately as extended community attributes. Hence, the correct answers are A, B, and C.

iMaster NCE-Campus adopts amulti-plane architectureto improve system security, scalability, and operational stability. The planes are logically isolated so that different types of traffic and functions do not interfere with each other. The two most commonly referenced planes are themanagement planeand theservice plane.

Themanagement planeis mainly responsible for system-level operations such as device registration, controller maintenance, system management, and internal communication between system components. For this purpose, it uses a dedicated access interface and port number to ensure secure and stable management connectivity.

Theservice plane, on the other hand, is designed fordaily network service operations. Administrators access this plane to perform tasks such as campus network planning, configuration delivery, monitoring, alarm viewing, and intelligent O&M operations. To keep service access independent and secure, the service plane uses its own dedicated login port.

According to HCIP Datacom Campus Network documentation, theservice plane of iMaster NCE-Campus uses port 18009. Administrators log in to the service plane by accessing the service IP address together with this port number. This separation ensures that service operations remain available even when management-plane functions are restricted or under maintenance.

Therefore, the correct port number for theservice planeis18009, making optionBthe 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.

Policy association is a core concept in Huawei campus network security design and is used to associate users, devices, and control elements for unified policy enforcement. According to HCIP Datacom Campus Network documentation, policy association definesthree fixed roles:Terminal,Access device, andControl device.

TheTerminalrepresents the end user or user device accessing the network. TheAccess deviceis typically a switch or wireless access device that provides network access and enforces authentication and authorization policies. TheControl device, such as an authentication or policy control node, is responsible for policy decision-making and centralized management.

APortal serveris not a role within policy association. Instead, it is aservice componentthat provides web-based authentication pages and user interaction during Portal authentication. While it participates in the overall authentication process, it does not belong to the policy association role model.

Therefore, among the given options,Portal serveris not one of the three defined policy association roles. This makesoption Bthe correct answer.

Telemetry is a next-generation network data collection technology designed to overcome the limitations of traditional SNMP polling. One of its major advantages is that it ismodel-driven, relying onYANG modelsto define structured and extensible data formats. This allows Telemetry to support various data types and provides stronger semantic meaning than SNMP MIBs, makingoption A correct.

Another key advantage ishigh-frequency data collection. Telemetry supportssecond-level or even sub-second-level reporting, enabling more precise and real-time network monitoring. This capability is critical for intelligent O&M scenarios such as fault prediction, traffic analysis, and SLA assurance. SNMP, by contrast, typically relies on periodic polling with much lower precision. Therefore,option D is correct.

Telemetry does not establish sessions based on SSH. Instead, it typically uses protocols such asgRPCover secure transport channels like TLS. Hence,option B is incorrect.

Option C is also incorrect because Telemetry focuses ondata subscription and reporting, not on configuring or managing device databases. Configuration management remains the responsibility of controllers or network management systems, not the Telemetry mechanism itself.

According to HCIP Datacom Campus Network documentation, Telemetry’s strengths lie in model-driven data representation and high-precision, real-time monitoring, making A and D the correct answers.
