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.

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.

Authentication Header (AH) is one of the core IPsec security protocols and is designed to provideauthentication and integrity protectionfor IP packets. AH ensures that the received packet is from a legitimate sender and that the packet has not been altered during transmission.

AH supportsdata origin authenticationby verifying the identity of the sender using cryptographic algorithms. It also providesdata integrity checking, ensuring that packet contents are not modified in transit. Additionally, AH supportsanti-replay protectionby using sequence numbers to prevent attackers from capturing and retransmitting valid packets.

However, AHdoes not provide data encryption. All packet contents, including payload data, remain visible on the network. This limitation is inherent to the AH protocol design and is one of the main reasons ESP is more widely used in modern IPsec deployments.

According to HCIP Datacom Campus Network documentation, if confidentiality through encryption is required, ESP must be used instead of AH. Therefore, the function not supported by AH is data encryption, making option D the correct answer.
