Huawei iMaster NCE-Campus supports multiplelicense business modelsto meet different customer deployment and commercial requirements.

TheGlobal perpetual license (N1 mode)is a traditional licensing model where licenses are purchased once and permanently authorized. It is commonly used in on-premises controller deployments and is therefore a supported model, makingoption A correct.

TheTenant Subscription license (SaaS mode)is designed for cloud-based deployments, especially in MSP or enterprise scenarios using Huawei Cloud services. In this model, tenants subscribe to services on a periodic basis, aligning with the SaaS delivery approach. This is a valid and supported licensing model, makingoption B correct.

TheGlobal perpetual license (a-la-carte mode)allows customers to flexibly purchase specific functional modules according to their needs rather than buying a bundled license. This model is also supported by iMaster NCE-Campus and is widely used for customized deployments, makingoption C correct.

TheGlobal subscription license (IaaS mode)is not a defined licensing business model for iMaster NCE-Campus. IaaS refers to infrastructure-level cloud services rather than application-level controller licensing. Therefore,option D is incorrect.

Hence, the correct answers are A, B, and C.

iMaster NCE-CampusInsight is anintelligent O&M analysis componentin Huawei’s CloudCampus Solution, designed to provide deep visibility, experience assurance, and fault diagnosis based onreal service traffic and user behavior. The statement is incorrect because CampusInsight doesnot rely on SNMP technologyto achieve its core capabilities.

According to HCIP Datacom Campus Network documentation, traditional SNMP is mainly used for basic device monitoring, such as interface status, CPU usage, memory usage, and simple alarms. SNMP focuses ondevice-level metricsand does not provide sufficient granularity to analyze application performance, user experience, or end-to-end service paths.

In contrast, iMaster NCE-CampusInsight usestelemetry, traffic sampling, flow analysis, and packet-level inspection technologiesto collect real-time and fine-grained data directly from network devices. These technologies allow CampusInsight to analyzeactual service traffic, identify application behavior, locate faults across the network path, and proactively detect network exceptions that affect user experience.

CampusInsight correlates data such as flow information, latency, packet loss, and service reachability to perform intelligent analysis and root cause identification. This enables capabilities like application experience assurance, abnormal traffic detection, and proactive fault prediction, which are beyond the scope of SNMP-based monitoring.

Therefore, because iMaster NCE-CampusInsight does not use SNMP as its primary data collection method and instead relies on advanced telemetry and traffic analysis technologies, the statement isFALSE.

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.

In IPsec, bothAuthentication Header (AH)andEncapsulating Security Payload (ESP)are implemented as IP protocols and are identified by specificIP protocol numbersin the IP header. These protocol numbers allow receiving devices to determine how the packet payload should be processed.

The protocol number assigned toAH is 51. AH provides data origin authentication, data integrity, and anti-replay protection but does not offer encryption. When an IP packet contains AH, the protocol field in the IP header is set to 51 so that the receiver can correctly process the AH header.

The protocol number assigned toESP is 50. ESP provides data confidentiality through encryption and can also provide integrity and authentication. Packets protected by ESP use protocol number 50 in the IP header.

The other options are incorrect because protocol number6represents TCP and17represents UDP, which are transport-layer protocols rather than IPsec protocols. Protocol number57is unrelated to IPsec.

According to HCIP Datacom Campus Network documentation and standard IP protocol assignments, the correct protocol numbers are AH = 51 and ESP = 50, making option B the correct answer.

SNMP and NETCONF are both commonly used network management protocols in campus networks, but they differ significantly in architecture, capabilities, and configuration management mechanisms. According to HCIP Datacom Campus Network documentation,NETCONF is designed for modern, model-driven network management, while SNMP is mainly used for monitoring and simple management.

Option A is incorrect because although both protocols use a client/server model, their roles are different. In SNMP, the managed device operates as an SNMP agent (server), while the NMS acts as the client. In NETCONF, the network device functions as the NETCONF server, and the management system is the client, not the other way around.

Option B is also incorrect because SNMP manages data using MIBs, whereas NETCONF usesdata models, typically based on YANG, instead of MIBs.

Option D is incorrect because SNMP does not support multiple configuration databases. It mainly provides basic read and write operations and is not suitable for complex configuration management or rollback.

Option C is correct. NETCONF provides alocking mechanismthat allows a client to lock a configuration datastore during configuration changes. This prevents multiple users or systems from modifying the same configuration simultaneously, avoiding conflicts and ensuring configuration consistency. This capability is a key advantage of NETCONF in intelligent campus network management and aligns with HCIP Datacom Campus Network best practices.

In astatic VXLAN tunneldeployment, MAC address learning relies ondata-plane trafficrather than a control-plane protocol. Unlike BGP EVPN-based VXLAN, where MAC and IP information is distributed through BGP, static VXLAN does not have a centralized or dynamic control mechanism to advertise host information.

As a result, VTEPs learn remote MAC addresses by inspectingencapsulated traffic, such as ARP request and reply packets, exchanged between hosts in the same VXLAN segment. When a host sends an ARP request, the local VTEP encapsulates the frame into a VXLAN packet and forwards it to the remote VTEP. Upon receiving the packet, the remote VTEP extracts the source MAC address and associates it with the corresponding VNI and tunnel endpoint.

This data-plane learning mechanism means that MAC address entries are built dynamically as traffic flows, which is why initial host communication may require broadcast or unknown unicast flooding. According to HCIP Datacom Campus Network documentation, this behavior is a defining characteristic of static VXLAN deployments.

Therefore, the statement isTRUE, and optionAis correct.

In a VXLAN BGP EVPN deployment, interconnection between Layer 2 and Layer 3 networks relies onIntegrated Routing and Bridging (IRB). According to HCIP Datacom Campus Network documentation, for a VPN instance to advertise its IP routes to the BGP EVPN control plane, the device must explicitly enable IRB route advertisement in the BGP view.

Theadvertise irbcommand is used to allow IP routes learned in a VPN instance to be advertised as EVPN Type 5 (IP Prefix) routes. These routes enable communication between different VNIs or between VXLAN segments and external Layer 3 networks. Without this command, the VPN instance routes remain local and are not distributed through the EVPN control plane, preventing proper Layer 3 connectivity across the VXLAN fabric.

The other options are incorrect in this context. Theadvertise vpnv4command is used in traditional MPLS VPN scenarios, not in BGP EVPN-based VXLAN networks. Theadvertise irbv6command is specific to IPv6 IRB scenarios and does not apply to IPv4 route advertisement unless explicitly required. Theadvertise l2vpn evpncommand is used to enable the EVPN address family itself but does not control the advertisement of IP routes from a VPN instance.

Therefore, to enable a VPN instance to advertise IP routes to the BGP EVPN address family in a VXLAN network, the correct command isadvertise irb.
