H12-841_V1.5 Huawei HCIP-Datacom-Campus Network Planning and Deployment V1.5 Free Practice Exam Questions (2026 Updated)

In campus network design, theegressis a critical point that connects the internal campus network to external networks such as the Internet or WAN. According to HCIP Datacom Campus Network architecture guidelines, ensuringhigh reliability at the egressis essential, even for small- and medium-sized campus networks, because external connectivity directly affects business continuity.

Deployingmulti-carrier linksat the egress is a recommended design practice to enhance reliability. Multi-carrier links refer to connecting the campus network todifferent service providersor independent external links. If one carrier experiences a failure, congestion, or maintenance issue, traffic can be switched to the backup carrier, ensuring uninterrupted external access. This approach significantly reduces the risk of service disruption caused by single-link or single-carrier failures.

For small- and medium-sized campuses, full redundancy with complex architectures may not be cost-effective. Multi-carrier backup links provide acost-efficient and practical solutionthat balances reliability and investment. Technologies such as static route backup, dynamic routing protocols, or policy-based routing can be used to implement automatic failover at the egress.

HCIP Datacom documentation emphasizes that egress reliability is not only a concern for large networks. Even smaller campuses require stable Internet and WAN access for cloud services, remote access, and centralized management platforms. Therefore, deploying multi-carrier links as backup at the egress is a valid and recommended design strategy.

Hence, the statement 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 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.

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 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.

IPsec VPN supports a variety ofsymmetric encryption algorithmsto protect data confidentiality during transmission. Commonly supported algorithms includeDES,3DES, andAES, all of which are used to encrypt the payload of IP packets in ESP.

AESis the most widely recommended algorithm due to its strong security and high performance.3DESandDESare legacy algorithms that are still supported for compatibility reasons, although they are considered less secure and are gradually being phased out in modern deployments.

DSA (Digital Signature Algorithm), however, isnot an encryption algorithm. It is an asymmetric algorithm used fordigital signatures and authentication, not for encrypting data. IPsec uses DSA only indirectly in certificate-based authentication scenarios, but it is never used as a data encryption algorithm in IPsec VPNs.

According to HCIP Datacom Campus Network documentation, IPsec VPN encryption relies exclusively on symmetric encryption algorithms such as DES, 3DES, and AES. Therefore,DSA is not supported as an IPsec encryption algorithm, makingoption Athe correct answer.

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.

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.

Comprehensive and Detailed Explanation (200–250 words):

In a VXLAN-based virtualized campus network, user terminals located in different access locations communicate with each other overVXLAN tunnelsestablished between VXLAN Tunnel Endpoints (VTEPs). These VXLAN tunnels form the overlay network, which abstracts the physical underlay and enables flexible Layer 2 and Layer 3 connectivity across the campus.

When communication is confined within the virtualized campus network, traffic remains inside the VXLAN overlay and is encapsulated and forwarded between VTEPs. However, when users or services inside the VXLAN network need to accessexternal networks, such as traditional IP networks, the Internet, or data centers that do not support VXLAN, traffic must exit the VXLAN overlay. This function is performed byborder nodes.

Border nodes act as the boundary between the VXLAN overlay and non-VXLAN networks. They are responsible for VXLAN encapsulation and decapsulation, routing between VXLAN segments and external networks, and enforcing security and policy controls at the network edge. According to HCIP Datacom Campus Network architecture principles, all traffic entering or leaving the VXLAN-based campus must pass through border nodes to ensure proper routing, policy enforcement, and service control.

Therefore, the statement is TRUE, and option A is correct.

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.
