Practice Free H19-404_V1.0 HCSE-Presales-Campus Network Planning and Design V1.0 Exam Questions Answers With Explanation

The statement is true. iMaster NCE-Campus supports multiple on-premises deployment combinations rather than being restricted exclusively to Huawei-branded physical servers and Huawei virtualization platforms. The training material explicitly lists physical-server deployment using SUSE Linux and a third-party server, as well as virtual-machine deployment using VMware.

The platform can also be deployed using Huawei server and virtualization combinations, including Huawei 2288X servers, EulerOS, FusionCompute, and TaiShan-based environments. The availability of several combinations enables customers to select an architecture consistent with their existing data-center standards, procurement strategy, virtualization environment, and operational requirements.

Huawei nevertheless identifies a recommended platform combination in the training material. A recommendation does not mean that the other listed combinations are unsupported; it identifies the preferred configuration for standardized deployment and support. The material displays third-party server plus SUSE Linux and VMware-based virtual-machine deployment as valid alternatives while recommending Huawei 2288X V5 plus EulerOS.

The deployment must still satisfy the specified CPU, memory, storage, network-interface, software-version, and compatibility requirements. Therefore, the statement is True.

==================

WAPI, or WLAN Authentication and Privacy Infrastructure, is the wireless LAN security standard proposed by China. It provides wireless link authentication and data-protection mechanisms and was developed as an alternative security framework for WLAN environments. Huawei’s training material explicitly identifies WAPI as a WLAN security standard proposed in China and states that it provides stronger protection than legacy WEP and WPA mechanisms.

WPA, WPA2, and WPA3 belong to the Wi-Fi Protected Access family maintained through Wi-Fi industry certification. WPA was introduced as an interim improvement over WEP. WPA2 adopted stronger IEEE 802.11i security mechanisms, including AES-based CCMP. WPA3 later introduced stronger password-authentication and enterprise-security options.

WAPI incorporates authentication and encryption as part of an integrated wireless security architecture. Its deployment depends on regional requirements, terminal compatibility, AP support, and the organization’s regulatory or cryptographic-policy obligations. The question asks which standard originated as a Chinese wireless security standard, not which standard is most widely deployed internationally. Therefore, WAPI is the only correct choice, making option B the verified answer.

==================

Huawei SD-WAN provides all four technologies. Per-flow load balancing distributes separate application flows among multiple links that have the same priority and satisfy the required SLA. Per-packet load balancing can transmit packets from one flow across multiple eligible links, improving aggregate bandwidth utilization for large file transfers, backups, and replication.

Multi-fed and selective receiving duplicates critical traffic across different links. The receiving device selects valid packets, removes duplicates, and preserves packet order. Packet loss or failure on one path therefore does not interrupt the service, enabling zero-millisecond link switchover in applicable deployments.

A-FEC dynamically generates redundant packets and adjusts the redundancy ratio according to measured packet loss. The receiving device reconstructs lost packets, reducing video freezing and voice-quality deterioration. Huawei describes both adaptive FEC and multi-fed selective receiving as WAN-optimization mechanisms for key traffic.

Intelligent traffic steering selects links according to application identity, quality, bandwidth, priority, and load. Therefore, A, B, C, and D are all correct.

==================

Professional security devices should be deployed at the headquarters or another centralized Internet-access site. Under centralized Internet access, branch Internet traffic is first carried through the SD-WAN overlay to the centralized gateway. The headquarters security infrastructure then performs access control and security inspection before forwarding the traffic to the Internet.

This approach is appropriate when branch CPEs lack sufficient processing capacity or advanced security functions. A centralized firewall or dedicated security platform can provide intrusion prevention, antivirus inspection, URL filtering, application control, content security, and unified logging. It also allows the enterprise to enforce one consistent security policy instead of maintaining separate advanced configurations at every branch.

Deploying advanced security capabilities on each CPE, as proposed in option C, is a distributed local-breakout design and does not satisfy the stated limitation concerning security-processing capability. Third-party cloud security services can be used in some site-to-cloud or secure Internet-access architectures, but they are not the intended headquarters-based centralized solution in this question.

Huawei explicitly states that centralized Internet traffic is diverted to the centralized access site and that the firewall function is deployed there to secure Internet services. Therefore, option D is correct.

==================

Authentication points should generally be placed on access devices close to the terminals. For wireless users, the AP or WLAN access device is the natural admission point because it directly controls the station’s wireless association and service access. For wired users, the access switch directly connects the endpoint and can enforce 802.1X, MAC-address authentication, VLAN authorization, ACLs, and security-group policies.

Huawei recommends access devices as authentication points for employees and specifically recommends access switches as authentication points for wired dumb terminals using MAC-address authentication. Deploying enforcement close to endpoints prevents unauthenticated or unauthorized traffic from traversing deeper into the campus network. It also improves fault isolation, policy granularity, and scalability because admission processing is distributed across access devices.

Option A is incorrect. A centralized authentication point can simplify configuration and policy management, but it does not inherently provide higher performance. It can create concentrated processing pressure, enlarge the Layer 2 scope, and allow unauthenticated traffic to travel farther before being evaluated. Therefore, the recommended principles are represented by B, C, and D.

==================

MRA, or Media Redundancy Auto-Manager, supports the automatic election of the Media Redundancy Manager in an MRP ring. When several devices are configured with the MRA role, they exchange control information and elect one device to perform the MRM function. The elected MRM supervises the ring, blocks one ring port during normal operation to prevent a Layer 2 loop, detects failures, and changes the forwarding state when the ring becomes open.

An MRC is a Media Redundancy Client. It participates in the MRP ring and forwards MRP control packets, but it does not initiate the automatic manager-election process. MRM represents the operational manager role after election or manual configuration, rather than the role specifically designed to support election. MIM refers to a Media Redundancy Interconnection Manager, which is associated with interconnecting and protecting multiple MRP rings rather than electing the manager within one ring. MRP itself distinguishes the ring manager from ring clients and uses the manager to control ring forwarding and recovery.

==================

AR routers support registration query center–based deployment, email-based deployment, and DHCP Option 148–based deployment. In registration query center deployment, the router obtains basic network connectivity, resolves or contacts Huawei’s registration service, retrieves the address and port of iMaster NCE, and then initiates registration. Huawei identifies AR routers, firewalls, switches, and APs as applicable devices for this method.

Email-based deployment is a major SD-WAN ZTP method for AR routers operating as CPEs. An administrator creates the site and ZTP configuration on iMaster NCE and sends a deployment URL to the onsite engineer. After the URL is opened and the parameters are written to the router, the device connects to the WAN and automatically registers with the controller.

DHCP Option 148 can provide the controller’s southbound IP address and port number to an IPv4 AR router, enabling automatic registration. Barcode scanning through the CloudCampus APP is specifically presented as an AP onboarding method, not an AR-router deployment method. Therefore, A, C, and D are correct.

Huawei SD-WAN supports full-mesh, hub-spoke, and partial-mesh interconnection models. In a full-mesh topology, every site can communicate directly with the other sites. This model minimizes intermediate forwarding and is appropriate when branches frequently exchange latency-sensitive traffic such as voice, video, or collaborative application data.

In a hub-spoke topology, branch sites communicate with a central headquarters or data-center hub. Branch-to-branch traffic normally traverses that hub. The model is simple, scalable, and suitable for enterprises whose applications and shared resources are concentrated at headquarters.

Partial-mesh is used when most sites can communicate directly but some sites lack direct underlay connectivity or do not require direct tunnels. Those sites can communicate through a redirect or intermediate site. Huawei describes full-mesh, hub-spoke, and partial-mesh as supported topology designs and explains the role of a redirect site in partial-mesh networking.

“Partial-spoke” is not a defined SD-WAN topology model. A spoke is a role within hub-spoke networking rather than an independent partial-spoke topology. Therefore, A, B, and D are correct.

==================

All four options represent objectives of a next-generation advanced industrial network. IP-based connections establish a standardized communications foundation, allowing production systems, controllers, sensors, machines, and management platforms to communicate through scalable Ethernet and IP technologies instead of isolated proprietary field networks.

Networked devices extend connectivity across operational technology assets so that equipment status, production data, and control information can be shared across production lines, plants, data centers, and cloud platforms. Network intelligence introduces automated provisioning, telemetry, analytics, fault prediction, policy optimization, and closed-loop operations. These capabilities reduce manual configuration and improve production availability.

Network-security integration is equally essential because greater openness and interconnection increase the potential attack surface. Security must therefore be integrated into access control, segmentation, device identification, encrypted communication, anomaly detection, and policy enforcement rather than added as an isolated external system. Huawei’s broader CloudCampus architecture similarly emphasizes automated provisioning, intelligent O & M, secure interconnection, integrated wired and wireless management, and open network capabilities. The four objectives collectively create an open, connected, intelligent, and secure industrial communications architecture.

==================

WIPS is the correct technology because it provides wireless intrusion prevention capabilities, including detecting and containing rogue access points, rogue stations, ad hoc devices, spoofing attempts, flood attacks, and other malicious activity on the radio interface. Huawei’s security-design material groups WIDS and WIPS with wireless attack detection and rogue-device containment. It recommends attack detection in public areas and primary or secondary education environments with high security requirements.

WIDS primarily detects and reports suspicious behavior, while WIPS adds active prevention or containment actions according to the configured policy. The other options serve different purposes. Mesh is a wireless networking architecture used to provide backhaul connectivity or extend coverage between APs; it is not an attack-detection mechanism. Spectrum analysis identifies non-Wi-Fi interference sources and evaluates radio-frequency utilization, but does not provide complete security attack detection and containment. Protected Management Frames protects selected 802.11 management frames against forgery, deauthentication, and disassociation attacks, but it is a protection mechanism rather than the comprehensive detection system requested. Therefore, WIPS is the correct answer.

==================

All four options are recognized terminal identification methods. MAC OUI examines the first three bytes of a device’s MAC address to determine its manufacturer, although it generally cannot identify the exact model or operating system. DHCP option identification analyzes fields such as DHCP options 12, 55, and 60, which can reveal the hostname, parameter-request list, vendor class, and other terminal characteristics. SNMP query is an active identification method that retrieves device details from relevant MIB objects and is particularly useful for printers, network devices, and other SNMP-capable equipment.

Nmap is also an active scanning method. It analyzes open ports, service responses, protocol behavior, and operating-system fingerprints to estimate a terminal’s device type and OS. Huawei distinguishes information-reporting methods from proactive scanning methods: MAC OUI and DHCP options generally use information observed in traffic, whereas SNMP and Nmap actively query or scan the endpoint. iMaster NCE-Campus can correlate multiple fingerprints to improve identification accuracy and automatically apply terminal-specific access policies.

==================

The statement is true in the context of Huawei’s AI-assisted application-identification architecture. Conventional identification depends mainly on predefined signatures, fixed destination addresses, port numbers, protocol fields, DNS correlation, or deep packet inspection. Huawei’s standard SD-WAN process uses Service Awareness and First-Packet Identification signature databases to identify and group application traffic. These mechanisms are effective for known applications but become less reliable when traffic is encrypted, applications change versions, or previously unseen applications appear.

A CNN-based classifier learns multidimensional traffic characteristics such as packet-length sequences, timing, direction, and flow behavior. It can classify traffic matching learned application patterns and, when implemented with open-set detection, recognize flows outside known classes as unknown or zero-day applications. Commercial-grade deep-learning traffic classification research demonstrates identification of known encrypted applications together with the handling of unknown zero-day applications.

This does not mean the system automatically assigns an exact commercial name to every unseen application. It detects that the traffic does not match established classes so that it can be investigated, labelled, and incorporated into later model updates. Therefore, the statement is True.

==================

iMaster NCE-Campus primarily improves the operations and maintenance experience in this solution. It provides centralized planning, deployment, configuration, policy orchestration, monitoring, topology management, device management, alarm handling, and maintenance through a unified graphical interface.

Instead of configuring each switch, AP, WAC, firewall, or router separately, administrators can define services and policies centrally and deliver them across the network. Huawei states that iMaster NCE-Campus provides integrated LAN and WAN management, integrated deployment, integrated policies, and integrated O & M, thereby improving deployment and O & M efficiency. It also provides network monitoring, service alarms, file management, log management, device maintenance, user management, and virtual-network management from one platform.

Wireless, wired, and application experience analysis is more directly associated with iMaster NCE-CampusInsight, which uses telemetry, AI, protocol tracing, and predictive analysis to quantify user and application experience. iMaster NCE-Campus serves as the management and control platform that simplifies administrators’ daily work. Therefore, the experience specifically improved by iMaster NCE-Campus is the O & M experience, making option C correct.
