H12-841_V1.5 Exam Dumps : HCIP-Datacom-Campus Network Planning and Deployment V1.5

Explanation (Concise and Technical)

Position 1 → 100This corresponds toVNI 100, which is associated with BD10 and is used for communication between PC1 and PC3.

Position 2 → 3.3.3.3This is theremote VTEP IP addressof VTEP3, configured as a head-end peer for VNI 100 on VTEP1.

Position 3 → 200This representsVNI 200, which is bound to BD20 and enables VXLAN communication between PC2 and PC4.

Position 4 → 1.1.1.1This is theremote VTEP IP addressof VTEP1, configured as a head-end peer for VNI 200 on VTEP2.

This mapping follows standardstatic VXLAN tunnel configuration logicon Huawei devices, where each VNI is explicitly associated with remote VTEP peer addresses using head-end peer-list.

In VXLAN-based networks, inter-subnet communication and external network access requireLayer 3 forwarding capabilities. ALayer 3 VXLAN gatewayperforms routing between different VXLAN segments (VNIs) and enables traffic to exit the VXLAN overlay toward traditional non-VXLAN networks.

The NVE interface is responsible only for VXLAN encapsulation and decapsulation and does not perform routing. VLANIF interfaces are used in traditional VLAN environments and do not provide VXLAN interworking. A Layer 2 VXLAN gateway supports bridging only and cannot route between subnets.

Therefore, the Layer 3 VXLAN gateway is the correct solution for inter-subnet communication and external access.

Huawei’s free mobility solution is designed to provide consistent user access control and policy enforcement across the campus network, regardless of user location. According to HCIP Datacom Campus Network documentation, the solution is built around severalclearly defined core roles, each with specific responsibilities.

Theauthentication deviceis a core role. It performs user authentication using methods such as 802.1X, MAC authentication, or portal authentication, and associates user identity information with IP addresses or security groups.

Thepolicy enforcement deviceis also a core role. It enforces security and access control policies based on IP-security group information, ensuring that traffic complies with defined policies wherever the user is connected.

iMaster NCE-Campusis another core component of the free mobility solution. It acts as the centralized management and control platform, responsible for policy definition, IP-security group management, and coordination of information distribution between authentication points and policy enforcement points.

Thepolicy control device, however, isnot a core roleexplicitly defined in Huawei’s free mobility architecture. Policy control functions are integrated into iMaster NCE-Campus rather than implemented as a separate standalone device role. Therefore, “policy control device” is not recognized as a core role in the free mobility solution.

As a result, option B is the correct answer, while the other options represent essential components of Huawei’s free mobility solution as defined in HCIP Datacom Campus Network materials.
