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

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 BGP EVPN-based VXLAN networks, route advertisement follows clearly defined standards regarding how endpoint and tunnel information is carried. According to HCIP Datacom Campus Network documentation,BGP EVPN does not use an EVPN Router MAC Extended Community to advertise the Router MAC of a VTEP. This statement is therefore incorrect.

In EVPN, different route types serve specific purposes. For example,EVPN Route Type 2 (MAC/IP Advertisement routes)are used to advertise MAC addresses (and optionally IP addresses) of endpoints. These routes associate endpoint information with a VTEP by using theBGP next-hop attribute, which contains the VTEP IP address. Similarly,EVPN Route Type 3 (Inclusive Multicast Ethernet Tag routes)also relies on the BGP next hop to identify the VTEP for VXLAN tunnel establishment and BUM traffic forwarding.

The Router MAC of a VTEP is alocal forwarding attribute, primarily used during VXLAN encapsulation and decapsulation on the device itself. It is not distributed through EVPN extended communities. While EVPN does define several extended communities for control and policy purposes, there is no standard or HCIP-defined “EVPN Router MAC Extended Community” used to carry the Router MAC field of a VTEP during route advertisement.

Therefore, based on HCIP Datacom Campus Network VXLAN EVPN principles, the statement is false.

Comprehensive and Detailed Explanation (200–250 words):

In this scenario,distributed VXLAN gatewaysare deployed, andlocal ARP proxyis enabled onVBDIF 10 of SW1. PC1 (172.16.1.1/24) needs to communicate with PC2 (172.16.1.2/24), which is located behind aremote distributed gateway (SW3).

Witharp-proxy local enable, SW1 doesnot flood ARP requests across the VXLAN tunnel. Instead, SW1 responds locally to PC1’s ARP request using theMAC address of its own VBDIF interface. Therefore, PC1 learns172.16.1.2 mapped to MAC D, which is the MAC address ofVBDIF 10 on SW1, not MAC B (the actual MAC of PC2). This makesstatement C trueandstatement A false.

Once PC1 sends traffic to PC2, the destination MAC in the frame isMAC D, meaning the packet is delivered to thelocal Layer 3 gateway. SW1 then performsLayer 3 routing, not Layer 2 switching. SW1 looks up theLayer 3 forwarding table, determines the remote VTEP, encapsulates the packet into VXLAN, and forwards it across the VXLAN tunnel. Therefore,statement D is true, whilestatement B is false.

This behavior aligns with HCIP Datacom Campus Network documentation fordistributed gateways with ARP proxy enabled, where traffic is routed locally and optimized across the VXLAN fabric.

In the Huawei free mobility solution based on iMaster NCE-Campus,IP-security groupsare used to associate user identities with IP addresses so that consistent security policies can be enforced regardless of user location. Apolicy enforcement point (PEP)must obtain IP-security group entries to correctly match traffic against security policies.

When the policy enforcement pointis not an authentication point, it cannot directly learn user identity information during access authentication. In this scenario, one supported method is to configureIP-security group entry subscriptionon iMaster NCE-Campus. After subscription is configured, iMaster NCE-Campus pushes the corresponding IP-security group entries to the policy enforcement point, which matches option A.

Another valid approach in this case is described in option B. If the authentication point and policy enforcement point are separate devices, theauthentication point can push IP-security group entriesto the policy enforcement point after successful user authentication. This ensures that enforcement devices receive real-time identity information.

If the policy enforcement pointalso functions as an authentication point, it can directly interact with iMaster NCE-Campus. In this scenario, iMaster NCE-Campusproactively pushes IP-security group entriesto the device, as stated in option C.

Option D is incorrect because iMaster NCE-Campus does not push IP-security group entries indiscriminately in all scenarios. The distribution mechanism depends on the role of the device and whether subscription or authentication-based pushing is configured.

Therefore, the correct answers are A, B, and C.

According to HCIP Datacom Campus Network architecture principles, campus networks can be classified from multiple dimensions to support scientific planning, design, and deployment. These classification methods help network designers select appropriate architectures, devices, and technologies based on actual service requirements.

Network scaleis a primary classification dimension. Campus networks are commonly divided into small, medium, and large-scale networks based on the number of users, terminals, access points, and network devices. This classification directly influences topology design, such as whether a simple two-layer architecture or a more scalable three-layer architecture is required.

Served objectsis another important classification method. Campus networks may serve office users, guests, teaching staff, students, production terminals, IoT devices, or video surveillance systems. Different served objects have different requirements for bandwidth, security, and access control, making this dimension critical for policy and service design.

Access moderefers to how users and devices connect to the campus network, including wired access, wireless access, or a hybrid of both. This classification impacts WLAN planning, authentication methods, and network access control strategies.

Service complexityreflects the types and number of services carried by the network. A campus network may provide basic data services or support complex services such as voice, video, cloud access, and industry applications. Higher service complexity requires more advanced network design and management capabilities.

Therefore, all listed options are valid classification methods for campus networks.

Encapsulating Security Payload (ESP) is one of the core protocols of the IPsec framework and is widely used in Huawei campus and SD-WAN network solutions to provide secure data transmission. ESP operates directly over IP and is identified by a uniqueIP protocol number, which allows network devices to recognize and process ESP packets correctly.

According to HCIP Datacom Campus Network documentation and standard IP protocol definitions,ESP uses protocol number 50. ESP provides essential security services such as data confidentiality through encryption, data integrity verification, authentication, and anti-replay protection. It can operate in bothtransport modeandtunnel mode, making it suitable for scenarios such as site-to-site VPNs and remote access VPNs.

The other options listed are incorrect.Protocol number 47is used by GRE (Generic Routing Encapsulation), which is a tunneling protocol and does not provide encryption.Protocol number 51is assigned to AH (Authentication Header), another IPsec protocol that provides integrity and authentication but does not support encryption.Protocol number 102is not associated with ESP or commonly used IPsec-related protocols.

Correct identification of ESP traffic using protocol number 50 is critical for firewall configuration, security policy enforcement, and proper forwarding of encrypted traffic in campus and WAN environments. Therefore, the correct answer is50, which corresponds to optionB.

In the Huawei CloudCampus Solution for small- and medium-sized campus networks,AR series routersare commonly deployed asegress gatewaysto provide Internet access, WAN connectivity, and centralized management integration. According to HCIP Datacom Campus Network documentation, AR devices supportmultiple deployment and management modes, ensuring flexibility during initial deployment and ongoing operations.

It is correct that an AR functioning as an egress gateway supportsweb-based network management, which allows administrators to perform basic configuration through a graphical interface. AR devices also supportregistration center query, enabling zero-touch provisioning by automatically discovering and registering with iMaster NCE-Campus. In addition,DHCP Option 148-based deploymentis supported, allowing the AR to obtain controller address information dynamically and establish a management connection.

However, the statement becomes incorrect when it claims thatCLI-based deployment is not supported. In fact, AR routers fully supportCLI-based configuration and deployment, which remains a fundamental management method in Huawei network devices. CLI access is widely used for initial configuration, troubleshooting, advanced feature configuration, and scenarios where automated or graphical tools are not available.

HCIP Datacom documentation emphasizes that CloudCampus deployment modes areadditive, not mutually exclusive. Web-based management, registration center onboarding, DHCP Option 148, and CLI can all coexist, giving administrators flexibility to choose the most suitable method based on deployment conditions.

Therefore, since AR devicesdo support CLI-based deployment, the statement is incorrect, and the correct answer isFALSE.

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.

The command output shows an EVPNRoute Type 2 (MAC Advertisement Route), which is used in VXLAN BGP EVPN fabrics to advertise host reachability information. The route clearly carries both aMAC address(b0d5-9dc7-3c41/48) and ahost IP address(172.16.1.173/32). In HCIP Datacom Campus Network VXLAN design, when a Type 2 route includes both MAC and IP information, it is classified as anIRB (Integrated Routing and Bridging) Type 2 route, enabling distributed gateways to perform Layer 2 forwarding and Layer 3 routing based on the same control-plane information. Therefore, statement A is correct.

Statement B is incorrect because ARP-related learning is not represented as a separate “ARP Type 2” EVPN route. EVPN uses MAC/IP Advertisement routes to distribute host reachability, not ARP-only route types.

Statement C is correct. The route containsRoute Target extended communities RT 0:2 and RT 0:3, which control EVPN route import. Any VPN instance configured with an import RT of 0:2 or 0:3 can successfully import this route and learn the corresponding host MAC and IP information.

Statement D is also correct. The output explicitly showsRT extended communitiesand theEVPN Router’s MACextended community. These attributes are essential for VXLAN tunnel identification, split-horizon forwarding, and correct EVPN operation in a campus fabric.

Hence, the correct answers are A, C, and D.

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.
