NEW QUESTION # 16
(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. After SW1 receives the packets sent from PC1 to PC2, SW1 searches the Layer 2 forwarding table and forwards the packets.
- B. After SW1 receives the packets sent from PC1 to PC2, SW1 searches the Layer 3 forwarding table and forwards the packets.
- C. The ARP entry on PC1 is 172.16.1.2 # MAC B.
- D. The ARP entry on PC1 is 172.16.1.2 # MAC D.
Answer: B,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.
NEW QUESTION # 17
In Huawei's WAN bandwidth management solution, which of the following functions can "limit bandwidth usage by different departments beyond their limits, such as limiting the speed to

- A. Only set bandwidth quotas; disconnect the network immediately after exceeding the quota.
- B. Bandwidth is set by user, without distinction by department.
- C. All departments share bandwidth, with no quotas or speed limits.
- D. Department-based bandwidth quotas and over-limit policies
Answer: D
NEW QUESTION # 18
In Huawei's SD-WAN solution, which of the following technologies can "ensure that the VPN tunnel data encryption algorithm between branches and headquarters is the national standard SM4, meeting the compliance requirements of information security level protection"?
- A. Unencrypted tunnel data, relying solely on MPLS label hiding.
- B. Automatically selects the encryption algorithm; it is not possible to manually specify the national standard encryption algorithm.
- C. It consistently uses international encryption algorithms (such as AES) and does not support Chinese national encryption algorithms.
- D. Specify the encryption algorithm as SM4 in the SD-WAN tunnel configuration.
Answer: D
NEW QUESTION # 19

NEW QUESTION # 22

- B. Configure routing policies on the PE device to import CE routes into the BGP VPNv4 address family.
- C. Configure the BGP protocol on the CE device to directly advertise the VPNv4 address family to the PE.

NEW QUESTION # 23
(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. Huawei public cloud
- C. MSP-owned cloud
- D. On-premise
Answer: B
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 # 24
(Fabric nodes need to be planned during fabric design on a CloudCampus virtualized campus network. Which of the following statements about node planning on a fabric is false?)
- A. If a BGP EVPN RR is required on a VXLAN network, BGP peer relationships need to be established between edge nodes and border nodes and between edge nodes.
- B. When the fabric needs to connect to two external networks located in different physical locations, two border nodes need to be deployed.
- C. It is recommended that access devices be deployed as edge nodes to implement end-to-end automatic VXLAN deployment.
- D. It is recommended that core devices be deployed as border nodes, and access or aggregation devices be deployed as edge nodes.
Answer: A
Explanation:
In a CloudCampus VXLAN fabric,node role planningis a fundamental design task that directly affects scalability, performance, and manageability. Huawei defines clear roles for fabric nodes, includingedge nodes, border nodes, and optionallyroute reflectors (RRs).
Statements A, B, and C correctly describe recommended design practices. Core devices are commonly deployed asborder nodesbecause they have higher performance and are well suited to connect the VXLAN fabric to external networks such as WANs or data centers. Access or aggregation devices acting asedge nodesenable end-to-end VXLAN automation and allow user traffic to be encapsulated and decapsulated close to the access layer. Additionally, when external networks exist in different physical locations, deployingmultiple border nodesimproves reliability and optimizes traffic paths.
Statement D is incorrect. In a VXLAN network usingBGP EVPN with route reflectors,edge nodes do not need to establish BGP peer relationships with each other. Instead, edge nodes establish BGP EVPN peer relationshipsonly with the RR, which centrally reflects EVPN routes to other nodes. This design significantly reduces the number of BGP sessions and improves scalability in large networks. Border nodes may also peer with the RR, but full-mesh peering between edge nodes is not required.
Therefore, the false statement isD, making it the correct answer.
