In a VXLAN-based virtualized campus network, theunderlay networkis responsible for providing basic IP connectivity between VXLAN Tunnel Endpoints (VTEPs). Statement D correctly describes this fundamental role of the underlay. Statement C is also correct, as VXLAN usesMAC-in-UDP encapsulationto overlay Layer 2 networks on top of a traditional IP infrastructure.

When iMaster NCE-Campus is used for automatic orchestration of the underlay routing domain,multiple routing protocols can be supported, depending on the solution version and design. Therefore, statementA is false, because OSPF is not the only supported routing protocol.

Statement B is correct in the context of standard automated deployment: iMaster NCE-Campus supportsOSPF single-area deploymentfor simplified orchestration and maintenance of the underlay network.

According to HCIP Datacom Campus Network architecture principles, the underlay must be stable, simple, and highly available, but it is not limited to a single routing protocol. Thus,option Ais the incorrect statement and the correct answer.

DHCP is a core protocol used in campus networks to automatically assign IP addresses and deliver network parameters to hosts, improving deployment efficiency and simplifying address management. DHCP messages include several fixed fields and anOptions field, which plays a critical role in parameter delivery.

Option A isfalse. Even if only gateway and DNS server information needs to be delivered to a client, the DHCP Offer messagemust carry the Options field. Default gateway and DNS server information are delivered through specific DHCP options, such as Option 3 (Router) and Option 6 (DNS Server). Without the Options field, these parameters cannot be conveyed to the client.

Option B is correct. The Options field in DHCP messages uses aTLV (Type-Length-Value)format, allowing flexible extension and supporting various network parameters, including NTP server addresses, wireless AC addresses, and log server addresses, which aligns with HCIP Datacom Campus Network descriptions.

Option C is also correct. DHCP supportsstatic IP address allocationby binding a specific IP address to a client’s MAC address. This is commonly used for printers, servers, or network devices that require fixed IP addresses.

Option D is correct as well. Because DHCP uses broadcast messages that cannot cross Layer 3 boundaries, aDHCP relay agentis required when the client and server reside on different IP networks.

Therefore, option A is the only incorrect statement.

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.
