NEW QUESTION # 109
(The following figure shows a policy control matrix on a virtualized network deployed using iMaster NCE- Campus. Which of the following statements about the policy control matrix are true?Choose all that apply.)
- A. If a user is not within Guest Group, Research Group, or Sales Group, that user cannot access any network resources.
- B. Users within Sales_Group can communicate with each other.
- C. Users in Guest_Group cannot communicate with those in Research_Group.
- D. Users in Research_Group cannot communicate with those in Guest_Group.
Answer: B,C,D
Explanation:
Comprehensive and Detailed Explanation (200-250 words):
In an iMaster NCE-Campus policy control matrix, rows representsource security groupsand columns representdestination security groups. A green check mark indicates that communication is allowed, while a red cross indicates that communication is denied. This matrix enables fine-grained user access control in VXLAN-based virtualized campus networks.
From the figure, communication betweenGuest_Group and Research_Groupis explicitly denied in both directions, as indicated by red crosses. Therefore, statementsAandDare both correct. The matrix also shows a green check mark forSales_Group communicating with itself, meaning intra-group communication is permitted, makingstatement B correct.
Theunknowngroup represents users that are not classified into Guest_Group, Research_Group, or Sales_Group. In the matrix, the unknown group is not completely blocked from all resources by default; access behavior depends on explicit policy configuration. Since the figure does not indicate a universal deny policy for unknown users toward all destinations,statement C is incorrect.
According to HCIP Datacom Campus Network policy control design, security group-based access control allows administrators to precisely define which user groups can communicate, improving security and service isolation. Hence, the correct answers areA, B, and D.
NEW QUESTION # 110

- B. Check if the firewall on the remote CE device is blocking data packets.
- C. Check if the MPLS LSP is established on the P device.
- D. Check if the BGP VPNv4 neighbor between PE devices is established normally.
Answer: A
NEW QUESTION # 111
(Which of the following statements about the fabric global resource pool isfalse?)
- A. A VXLAN network identifier identifies a VXLAN.
- B. Configure a service VLAN pool when you need to configure external gateway interconnection VLANs, network service resource interconnection VLANs, management VLANs for policy association, and VN access VLANs.
- C. A bridge domain is a Layer 2 broadcast domain used to forward data packets on a VXLAN.
- D. VLANs for connecting to external networks, VLANs for connecting to network service resources, and VLANs for connecting underlay devices are allocated from the VLAN resource pool.
Answer: D
Explanation:
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
In a CloudCampus VXLAN fabric, theglobal resource poolcentrally manages identifiers such as VLANs, VNIs, and bridge domains to ensure consistent allocation across the fabric.
StatementAis correct because abridge domain (BD)is the VXLAN equivalent of a VLAN and represents a Layer 2 broadcast domain used for packet forwarding within a VXLAN network.
StatementCis also correct. AVXLAN Network Identifier (VNI)uniquely identifies a VXLAN segment and is a core VXLAN forwarding identifier.
StatementDis correct because theservice VLAN poolis used to allocate VLANs for multiple purposes, including external gateway interconnections, network service resource interconnections, policy association management, and VN access VLANs.
StatementBis false. VLANs used forunderlay device interconnectionsarenot allocated from the VLAN resource poolmanaged by the VXLAN fabric. Underlay VLANs belong to the traditional IP underlay network and are typically planned and configured independently. The VLAN resource pool is intended for overlay-related services and fabric-managed VLAN usage only.
Therefore, the incorrect statement isB.

(Which of the following are iMaster NCE-Campus license business models?Choose all that apply.)
- A. Tenant Subscription license (SaaS Mode)
- B. Global perpetual license (a-la-carte mode)
- C. Global perpetual license (N1 mode)
- D. Global subscription license (IaaS Mode)
Answer: A,B,C
Explanation:
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
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.
NEW QUESTION # 115

NEW QUESTION # 116
(A supermarket chain wants to manage all its branch networks through iMaster NCE-Campus. However, it does not want to purchase physical servers or software. In this case, which of the following deployment modes is recommended?)
- A. Cloud management
- B. MSP-owned cloud
- C. On-premise
- D. Huawei public cloud
Answer: D
Explanation:
iMaster NCE-Campus supports multiple deployment modes to meet the needs of different enterprise customers, including on-premise deployment, MSP-owned cloud deployment, and Huawei public cloud deployment. The choice of deployment mode mainly depends on whether the customer wants to invest in infrastructure, manage the platform independently, or use a fully hosted service.
In this scenario, the supermarket chain explicitlydoes not want to purchase physical servers or software, which means an on-premise deployment is not suitable. On-premise mode requires customers to prepare hardware resources, install software, and maintain the system themselves. Similarly, an MSP-owned cloud deployment typically involves a managed service provider hosting the platform, which may still require contractual dependency on a third party and is not the most straightforward option for enterprises seeking minimal investment and simplified operations.
According to HCIP Datacom Campus Network documentation, theHuawei public cloud deploymentis recommended for customers who want acloud-based, subscription-oriented solution. In this mode, iMaster NCE-Campus is hosted and operated on Huawei Cloud. Customers only need to register and subscribe to the service, without purchasing servers, storage, or management software. Huawei is responsible for system maintenance, upgrades, security, and high availability.
This deployment model is especially suitable forretail chains and multi-branch enterprises, such as supermarkets, because it enables centralized management of geographically distributed branch networks with low initial investment and fast rollout.
Therefore, the recommended deployment mode in this case isHuawei public cloud, making optionCthe correct answer.

NEW QUESTION # 123
(As shown in the figure, distributed VXLAN gateways are used, and thearp-proxy local enablecommand is configured onVBDIF 10 of SW1. Which of the following statements aretrue?)
- A. The ARP entry on PC1 is 172.16.1.2 # MAC B.
- B. After SW1 receives the packets sent from PC1 to PC2, SW1 searches the Layer 2 forwarding table and forwards the packets.
- C. After SW1 receives the packets sent from PC1 to PC2, SW1 searches the Layer 3 forwarding table and forwards the packets.
- D. The ARP entry on PC1 is 172.16.1.2 # MAC D.
Answer: C,D
Explanation:
Comprehensive and Detailed Explanation (200-250 words):
In this scenario,distributed VXLAN gatewaysare deployed, andlocal ARP proxyis enabled onVBDIF 10 of SW1. PC1 (172.16.1.1/24) needs to communicate with PC2 (172.16.1.2/24), which is located behind aremote distributed gateway (SW3).
Witharp-proxy local enable, SW1 doesnot flood ARP requests across the VXLAN tunnel. Instead, SW1 responds locally to PC1's ARP request using theMAC address of its own VBDIF interface. Therefore, PC1 learns172.16.1.2 mapped to MAC D, which is the MAC address ofVBDIF 10 on SW1, not MAC B (the actual MAC of PC2). This makesstatement C trueandstatement A false.
Once PC1 sends traffic to PC2, the destination MAC in the frame isMAC D, meaning the packet is delivered to thelocal Layer 3 gateway. SW1 then performsLayer 3 routing, not Layer 2 switching. SW1 looks up the Layer 3 forwarding table, determines the remote VTEP, encapsulates the packet into VXLAN, and forwards it across the VXLAN tunnel. Therefore,statement D is true, whilestatement B is false.
This behavior aligns with HCIP Datacom Campus Network documentation fordistributed gateways with ARP proxy enabled, where traffic is routed locally and optimized across the VXLAN fabric.
