Pass the Huawei HCIP-Datacom H12-841_V1.5 Questions and answers with CertsForce

In Huawei campus WLAN solutions, different WLAN architectures are designed to meet varying network scales, cost requirements, and management complexity. The architecture described in this question matches theLeader APsolution.

ALeader APcan operate independently without a dedicated wireless controller, while also having the capability to manage asmall number of subordinate APs. The Leader AP takes on lightweight control functions, such as basic configuration management and simple roaming coordination among the managed APs. This allows wireless users to roam between APs with minimal service interruption, meeting basic mobility requirements.

According to HCIP Datacom Campus Network documentation, the Leader AP architecture is characterized bylow deployment cost and simple maintenance. Since no separate AC is required and the number of APs is limited, network planning and configuration are straightforward. This significantly reduces the technical skill level required for daily operation and maintenance, making it suitable for small campuses, retail stores, branch offices, and small enterprises.

In contrast,Fat APsoperate completely independently and do not support centralized roaming management.AC + Fit AParchitectures are designed for medium to large networks and require higher investment and professional maintenance.Agile distributed APsolutions focus on centralized APs and RUs, which do not align with the independent AP management described.

Therefore, the WLAN architecture that best fits the given characteristics isLeader AP, making optionAthe correct answer.

In iMaster NCE-Campus–based virtualized campus networks, thesiteis a fundamental management object used to organize and manage network resources. A site typically represents aphysical location or logical network scope, such as a campus, building, or branch, under a tenant. Tenants manage devices, configurations, and servicesby site, which makes statementB correct.

iMaster NCE-Campus allows administrators tocreate sites individually, enabling flexible deployment and incremental network construction. Therefore,statement C is correct. In addition, a site is created and owned by atenant administratorto represent the tenant’s network scope, makingstatement D correct.

StatementA is false. iMaster NCE-Campusdoes support batch site creation, which is commonly used in large-scale or MSP scenarios where many tenant sites or branch sites need to be deployed efficiently. Batch creation significantly reduces manual workload and improves deployment efficiency.

According to HCIP Datacom Campus Network documentation, site management supports bothsingle-site creation and batch site creation, enabling scalable and centralized O&M. Therefore, the statement claiming that batch site creation is not supported is incorrect.

In the Huawei CloudCampus Solution, the architecture is typically divided into themanagement layerand thenetwork layer. The management layer, represented by platforms such as iMaster NCE-Campus, is responsible for centralized configuration, monitoring, policy delivery, and intelligent O&M. Communication between these two layers relies on standardizedmanagement and control protocols.

NETCONFis a key protocol used between the management layer and network devices. It provides a structured and reliable mechanism for delivering configurations, querying device status, and performing automated service deployment. NETCONF works closely with data models to ensure consistency and accuracy in configuration management.

SNMPis also widely used in the CloudCampus Solution for monitoring and fault management. Through SNMP, network devices report performance data, alarms, and status information to the management platform, enabling real-time visibility and proactive maintenance.

YANGis not a transport protocol but a data modeling language; however, it plays a critical role in management-layer communication. YANG models define the structure of configuration and operational data exchanged between the controller and devices, typically carried over NETCONF. Therefore, YANG-related information is effectively exchanged between the management and network layers.

RADIUS, on the other hand, is used for user authentication, authorization, and accounting. It operates between network devices and authentication servers, not between the management layer and the network layer.

Thus, the correct options areNETCONF, SNMP, and YANG.

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.

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 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.

In a Huawei VXLAN BGP EVPN architecture,Route Targets (RTs)play a critical role in controlling route import and export between VPN instances on different VTEPs. When a BGP EVPN route is received by a VTEP, the device determines whether the route should be accepted or discarded based on RT matching rules.

According to HCIP Datacom Campus Network documentation, a received EVPN route is considered validas long as its RT matches either the EVPN Import Route Target (EVPN IRT) or the IP VPN Import Route Target (IP VPN IRT)configured on the local device. This design enables flexible route sharing between Layer 2 EVPN services and Layer 3 VPN services, supporting integrated routing and bridging (IRB) scenarios and inter-VNI communication.

If the RT carried in the EVPN route matches at least one of these import RTs, the route is imported into the corresponding VPN instance and can be used for traffic forwarding. Only when the RT doesnot match both the EVPN IRT and the IP VPN IRTwill the route be discarded. This mechanism ensures proper isolation between tenants while still allowing controlled route exchange where required.

Therefore, the statement accurately describes the EVPN route filtering logic used between VTEPs in Huawei VXLAN networks. The route is discardedonly when the RT differs from both configured import RTs, making the statementTRUE.

To prevent users from accessing the network using statically configured IP addresses, Huawei campus networks rely on a combination ofDHCP SnoopingandIP Source Guard (IPSG). DHCP Snooping works by monitoring DHCP message exchanges and building atrusted binding tablethat records legitimate IP–MAC–VLAN–interface mappings learned dynamically from a legal DHCP server. This binding table becomes the foundation for several Layer 2 security mechanisms.

IP Source Guard uses the DHCP Snooping binding table to strictly control traffic entering an interface. When IPSG is enabled, the switch permits only packets whose source IP address and MAC address match an entry in the DHCP Snooping binding table. If a user manually configures a static IP address, no valid DHCP binding exists for that host, so IPSG drops the traffic and denies network access. This directly prevents statically configured IP addresses from being used to access the network.

Dynamic ARP Inspection (DAI) focuses on preventing ARP spoofing and man-in-the-middle attacks, not static IP misuse. Port Security limits MAC addresses per interface but does not verify IP address legitimacy. Therefore, neither DAI nor Port Security alone can prevent users from assigning static IP addresses.

According to HCIP Datacom Campus Network security design principles,only the combination of DHCP Snooping and IPSGeffectively enforces IP address legitimacy and blocks statically configured IP access, making optionCthe correct answer.

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 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.
