In Huawei campus access authentication designs, network access is divided intopre-authentication,isolation, andpost-authenticationdomains to control user access at different stages of authentication.

Thepre-authentication domainprovides users with only the most basic network services required to initiate authentication. These services typically includeDHCPandDNS. DHCP allows unauthenticated terminals to obtain IP addresses and basic network parameters, while DNS enables domain name resolution so that users can reach authentication portals or admission servers. Therefore,DHCP and DNS servers are essential components of the pre-authentication domain, making optionsC and D correct.

AnFTP serveris a general-purpose file transfer service and is not required for user authentication. Anantivirus serverbelongs to theisolation domain, where users are redirected if authentication fails or if their devices do not meet security posture requirements, such as outdated virus signatures. These servers provide remediation resources but are not part of the pre-authentication process.

According to HCIP Datacom Campus Network documentation, limiting the pre-authentication domain to only essential services reduces security risks while ensuring successful user onboarding.

1 →dh group1

2 →main

3 →esp

4 →tunnel

In the IKE proposal, the Diffie-Hellman group defines the key exchange strength used during IKE Phase 1 negotiation, which is whydh group1corresponds to position 1 under the IKE proposal configuration. Theexchange-mode mainsetting is part of IKEv1 Phase 1 and therefore correctly matches position 2 under the IKE peer configuration.

For the IPsec proposal, thetransformspecifies the protocol used to protect data traffic; since ESP is explicitly required,espcorrectly maps to position 3. Finally, theencapsulation-mode tunneldefines how packets are encapsulated in IPsec VPNs between gateways, makingtunnelthe correct match for position 4.

This mapping strictly follows HCIP Datacom Campus Network IPsec and IKE configuration logic and aligns with standard Huawei VRP command behavior.

In campus network architecture, theegress zoneplays a critical role as the boundary between the internal campus network and external networks such as the Internet, WAN, or cloud services. According to HCIP Datacom Campus Network design principles, the egress zone must meet multiple functional and security requirements to ensure stable, secure, and flexible network operation.

First,network connectivityis a fundamental requirement. The egress zone must reliably connect the campus intranet to external networks, ensuring uninterrupted access to external resources and services. High availability and redundancy are often considered in this aspect to avoid single points of failure.

Second,network secure ensuranceis essential. As the main security boundary, the egress zone must protect the campus network from external threats. This typically involves deploying security mechanisms such as firewalls, intrusion prevention, traffic filtering, and attack defense to ensure data and service security.

Third, the egress zone must provide strongservice control capability. This includes traffic identification, policy-based forwarding, bandwidth management, and application control. These capabilities allow administrators to optimize service quality, prioritize critical applications, and manage user access to external services.

Finally,various and flexible access modesare required to support different external connection scenarios, such as Internet access, MPLS WAN access, VPN connections, and cloud interconnection. This flexibility enables the campus network to adapt to evolving business and service requirements.

Therefore, all listed options are essential requirements for proper egress zone design, makingA, B, C, and Dthe correct answers.

CloudCampus virtualized campus networks support multiplefabric egress modesto connect VXLAN fabrics to external networks. These modes determine how traffic exits the fabric and whether egress resources are shared among multiple virtual networks.

Layer 3 shared egressallows multiple VNs to share the same Layer 3 egress interface, improving resource utilization and simplifying external connectivity.Layer 3 exclusive egressdedicates an independent Layer 3 interface to a specific VN, providing stronger isolation and higher security.

Layer 2 shared egressenables multiple VNs to access an external Layer 2 network through a shared interface. This mode is commonly used when the external network does not support Layer 3 integration.

Layer 2 exclusive egressis not supported in the CloudCampus solution because Layer 2 resources are typically designed to be shared to optimize scalability and simplify deployment.

Therefore, the correct answers are A, C, and

D.
