Pass the Huawei HCSP Presales H19-404_V1.0 Questions and answers with CertsForce

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.

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

All four statements correctly describe the trade-offs between direct and tunnel forwarding. With direct forwarding, an AP sends service traffic directly to the upstream network rather than encapsulating it in a CAPWAP data tunnel to the WAC. This eliminates unnecessary detours, avoids creating a WAC bandwidth bottleneck, reduces WAC load, and generally provides higher forwarding efficiency.

However, on a fabric network, Layer 3 roaming across different edge nodes may require the original edge or another designated device to remain the home agent. The resulting forwarding path and state synchronization can slightly affect roaming performance, making direct forwarding less suitable for extremely roaming-sensitive deployments. Huawei’s material explains that after Layer 3 roaming in direct-forwarding mode, traffic may continue to be forwarded through the home agent.

Tunnel forwarding sends AP service traffic through CAPWAP tunnels to the WAC. This simplifies centralized policy enforcement, security control, and traffic management. Its disadvantage is that all wireless traffic may detour through the WAC, increasing forwarding pressure and potentially creating a performance bottleneck.

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

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.

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

The two IPsec encapsulation modes are transport mode and tunnel mode. In transport mode, IPsec protects the upper-layer payload of the original IP packet while retaining the original IP header as the packet’s outer header. It is commonly associated with end-to-end host communication, although it can also protect a GRE packet between tunnel endpoints.

In tunnel mode, IPsec protects the complete original IP packet and adds a new outer IP header containing the addresses of the IPsec peers. This mode is commonly used between security gateways, routers, or site-to-site VPN endpoints because the original source and destination information can be protected within the encrypted inner packet. RFC 4301 formally defines transport and tunnel as the two IPsec security-association modes.

AH and ESP are not encapsulation modes. They are IPsec security protocols. Authentication Header provides integrity and source authentication but not encryption. Encapsulating Security Payload can provide encryption, integrity, authentication, and anti-replay protection. Either protocol can conceptually operate in transport or tunnel mode, although ESP is overwhelmingly used for encrypted enterprise VPN and SD-WAN data channels.

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

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.

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

Option B is false because it reverses the encapsulation behavior. In IPsec transport mode, the IPsec security header is inserted after the existing IP header; a new outer IP header is not normally added. In tunnel mode, the complete original IP packet is encapsulated and a new outer IP header is added. Tunnel mode therefore generally introduces greater overhead and produces a longer packet than transport mode, not the reverse.

The remaining statements are correct. IPsec supports both transport and tunnel modes. GRE over IPsec performs GRE encapsulation first, allowing GRE to transport the original payload, and then applies IPsec protection to the resulting GRE packet. The IPsec security association is established between the GRE tunnel endpoints, protecting the GRE-encapsulated traffic as it traverses an untrusted transport network.

Huawei SD-WAN data channels can use either GRE or GRE over IPsec. GRE provides flexible overlay encapsulation, while IPsec adds confidentiality, integrity, origin authentication, and anti-replay protection for site-to-site traffic. Huawei specifically identifies IPsec encryption as the mechanism securing site-to-site SD-WAN services.

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

Huawei switches’ unauthorized access prevention function can prevent users from connecting unauthorized hubs and sharing network access through unauthorized Wi-Fi hotspots. An unauthorized hub allows multiple terminals to enter the network through a port intended for a single managed endpoint. This can bypass normal terminal-count limitations, admission controls, and access-policy enforcement.

Unauthorized Wi-Fi hotspot sharing occurs when a user connects an authenticated endpoint to the enterprise network and then enables hotspot or connection-sharing functionality. Other terminals can subsequently access the network through that endpoint without completing the required authentication process. Huawei switches can analyze terminal behavior, MAC-address relationships, packet characteristics, and access patterns to identify and restrict this behavior.

A USB flash drive is a local storage device and does not provide Ethernet network access, so option A is unrelated to switch-based unauthorized network access prevention. An unauthorized router is normally controlled through device identification, NAC, port security, or explicit access policies rather than the specific hub and hotspot-sharing prevention function described by this question.

Huawei intelligent terminal management combines terminal identification, authorization, traffic analysis, and bogus-terminal detection to achieve visualized access and prevent unauthorized connectivity.

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

The statement is true. AI-based energy-saving systems analyze historical traffic and usage patterns to predict periods of low network demand. Ordinary AP radios or access devices can then enter an energy-saving state when their capacity is not required, while surrounding devices maintain sufficient coverage and service availability.

IoT APs, however, may host continuously operating IoT cards, sensors, electronic shelf-label services, Bluetooth location functions, RFID services, healthcare devices, or asset-tracking terminals. Placing such an AP into an energy-saving or hibernation state could interrupt more than ordinary Wi-Fi connectivity. It could also disable an IoT module’s power supply, management channel, data backhaul, or persistent sensing function. Huawei’s Wi-Fi and IoT convergence architecture uses APs as shared locations, power sources, and communication channels for IoT services.

Huawei also applies intelligent technologies to analyze AP load trends and perform predictive network optimization. The safer default is therefore to exclude IoT APs from automatic energy-saving actions unless the administrator confirms that their attached IoT services tolerate interruption. Accordingly, the answer is True.
