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.

In a VXLAN-based campus or data center network, different node roles are defined to ensure proper traffic forwarding between traditional networks, the VXLAN overlay, and external networks. According to HCIP Datacom Campus Network documentation,edge nodes(also known as VTEPs) are responsible for encapsulating and decapsulating traffic between traditional Layer 2 or Layer 3 networks and the VXLAN overlay network. This allows legacy networks to communicate with virtualized VXLAN segments.

However, when traffic needs to leave the VXLAN fabric and accessexternal networks, such as a WAN, Internet, or another non-VXLAN domain, theborder nodeis used. The border node sits at the boundary of the VXLAN fabric and provides interconnection between the VXLAN network and external routing domains. It performs functions such as VXLAN termination, route advertisement, and traffic forwarding between overlay and underlay or external networks.

In BGP EVPN-based VXLAN deployments, the border node typically participates in BGP routing to exchange reachability information with external devices, ensuring seamless communication between VXLAN tenants and outside networks. This architectural separation improves scalability, simplifies network design, and enhances control over traffic entering or leaving the VXLAN fabric. Therefore, the correct node through which a VXLAN network accesses an external network is theBordernode.

iMaster NCE-Campus supports multiple deployment modes to meet the needs of different enterprise customers, including on-premise deployment, MSP-owned cloud deployment, and Huawei public cloud deployment. The choice of deployment mode mainly depends on whether the customer wants to invest in infrastructure, manage the platform independently, or use a fully hosted service.

In this scenario, the supermarket chain explicitlydoes not want to purchase physical servers or software, which means an on-premise deployment is not suitable. On-premise mode requires customers to prepare hardware resources, install software, and maintain the system themselves. Similarly, an MSP-owned cloud deployment typically involves a managed service provider hosting the platform, which may still require contractual dependency on a third party and is not the most straightforward option for enterprises seeking minimal investment and simplified operations.

According to HCIP Datacom Campus Network documentation, theHuawei public cloud deploymentis recommended for customers who want acloud-based, subscription-oriented solution. In this mode, iMaster NCE-Campus is hosted and operated on Huawei Cloud. Customers only need to register and subscribe to the service, without purchasing servers, storage, or management software. Huawei is responsible for system maintenance, upgrades, security, and high availability.

This deployment model is especially suitable forretail chains and multi-branch enterprises, such as supermarkets, because it enables centralized management of geographically distributed branch networks with low initial investment and fast rollout.

Therefore, the recommended deployment mode in this case isHuawei public cloud, making optionCthe correct answer.
