In a VXLAN BGP EVPN network, different EVPN route types are used to advertise specific kinds of control-plane information.BGP EVPN Type 2 routes, also known asMAC/IP Advertisement routes, are primarily used to advertise Layer 2 and host-level Layer 3 reachability information between VTEPs.

According to HCIP Datacom Campus Network documentation, a Type 2 route carriesMAC address information, and it can optionally carry ahost IP addressassociated with that MAC. This enables efficient MAC learning and ARP suppression within the VXLAN fabric. TheL2VNIis also included in Type 2 routes, as it identifies the Layer 2 broadcast domain to which the MAC and IP information belongs.

TheL3VNIis not used to identify a Layer 2 broadcast domain but is associated with Layer 3 VPN forwarding and inter-VNI routing. While L3VNI information is relevant in EVPN-based Layer 3 services, it is not the primary identifier in a Type 2 route. However, the key distinction in this question lies in the difference between host routes and prefix routes.

AnIP prefixrepresents a network segment rather than a single host and is advertised usingEVPN Type 5 (IP Prefix) routes, not Type 2 routes. Type 2 routes only carry host IP addresses, not IP prefixes. Therefore,IP Prefixis not carried in a BGP EVPN Type 2 route, making optionCthe correct answer.

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 a CloudCampus virtualized campus network,Virtual Networks (VNs)provide service isolation, whilesecurity groupsenable identity-based access control. Even when inter-VN routing is technically available, communication between users in different VNs isnot permitted by default. Access permissions are controlled bysecurity group–based policies.

To allowR&D personnel and sales personnelto communicate, the network administrator must explicitly define thesecurity policy relationshipbetween the two security groups. This is achieved by deploying apolicy control matrixon iMaster NCE-Campus. The policy control matrix specifies whether traffic between source and destination security groups is allowed or denied and enforces the policy on relevant network devices.

Deploying an external network is unnecessary because communication is required within the campus network. Configuring access management relates to authentication and authorization during network access, not inter-group communication control. Configuring inter-VN communication enables routing capability but does not definewhethercommunication is permitted at the security policy level.

According to HCIP Datacom Campus Network documentation,security group communication permissions are controlled through the policy control matrix, making optionAthe correct task to meet the requirement.

iMaster NCE-Campus adopts a flexiblemulti-plane networking architectureto meet different deployment scale and reliability requirements. According to HCIP Datacom Campus Network documentation, iMaster NCE-Campus supports bothsingle-plane networkingandmulti-plane networking, and the selection depends on the system deployment mode.

In asingle-node system deployment, all functional components of iMaster NCE-Campus run on a single node. In this scenario,single-plane networking is optionaland can be used to simplify network planning and reduce deployment complexity. Management traffic, service traffic, and internal communication share the same network plane, which is sufficient for small-scale or test environments where high availability and strict isolation are not mandatory.

However, inmulti-node or cluster deployments, iMaster NCE-Campus requiresmulti-plane networking. Different network planes—such as management plane, service plane, and internal communication plane—are deployed separately to ensure high availability, scalability, performance isolation, and security. Single-plane networking isnot supportedin these deployments because it cannot meet the reliability and performance requirements of clustered systems.

This design ensures that large-scale campus networks benefit from fault isolation and load separation, while smaller deployments can use a simplified architecture. Therefore, the statement that single-plane networking is optional only in single-node system deployment is consistent with HCIP Datacom Campus Network design principles.

Hence, the correct answer isTRUE.
