NEW QUESTION # 61
(Which of the following statements about the underlay network of a VXLAN-based virtualized campus network isfalse?)
- A. When iMaster NCE-Campus is used to implement automatic orchestration of the routing domain on the underlay network, only OSPF single-area deployment is supported.
- B. When iMaster NCE-Campus is used to implement automatic orchestration of routing domains on the underlay network, only OSPF is supported.
- C. The underlay network provides IP reachability so that VXLAN-encapsulated service packets can be transmitted between VTEPs.
- D. The virtualized campus network solution introduces VXLAN technology, which uses MAC-in-UDP encapsulation to build a logical network over a traditional IP network.
Answer: B
Explanation:
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
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 supports OSPF 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.

NEW QUESTION # 68
(On a virtualized network deployed using iMaster NCE-Campus, after an administrator performs an operation, iMaster NCE-Campus delivers the following configuration to devices. Which of the following operations did the administrator perform?) acl number9997 rule1permit ip source ucl-groupnameResearch_Group destination ucl-groupnameSales_Group rule2permit ip source ucl-groupnameResearch_Group destination ucl-groupnameGuest_Group
- A. Create a security group.
- B. Create an authorization result.
- C. Deploy inter-VN communication.
- D. Deploy a policy control matrix.
Answer: D
Explanation:
In a virtualized campus network managed byiMaster NCE-Campus, traffic control between users or user groups is implemented throughsecurity groupsand apolicy control matrix. The configuration shown clearly reflects this mechanism.
The ACL usesucl-group names, such asResearch_Group,Sales_Group, andGuest_Group. These ucl-groups correspond tosecurity groupsdefined on iMaster NCE-Campus. The ACL rules explicitly permit IP traffic from one security group to other security groups. This type of ACL is automatically generated and delivered by the controller when apolicy control matrixis deployed.
A policy control matrix defineswho can access whomby specifying allow or deny relationships between security groups. Once the matrix is configured on iMaster NCE-Campus, the controller translates these logical policies into device-level ACLs and applies them to the appropriate enforcement points in the VXLAN fabric.
The presence of multiple rules permitting traffic from one group to multiple destination groups is a typical outcome of deploying such a matrix.
Creating a security group alone would not generate ACL rules. Deploying inter-VN communication would involve route exchange or gateway configuration, not ucl-group-based ACLs. Creating an authorization result would associate users with security groups but would not generate inter-group ACL rules.
Therefore, the administrator operation that resulted in this configuration wasdeploying a policy control matrix, making optionAthe correct answer.

NEW QUESTION # 81
Drag the user authentication results to the corresponding network access rights.
Answer:
Explanation:
Explanation:
* Position 1 # Before authenticationBefore users are authenticated, they are placed in thepre- authentication domain. At this stage, access is strictly limited to basic network services such as the Admission server,DHCP server, andDNS server. This allows users to obtain IP addresses and reach authentication-related services only.
* Position 2 # Upon authentication failuresIf user authentication fails or security posture checks (such as antivirus or patch verification) do not pass, users are redirected to theisolation domain. In this domain, access is restricted to remediation resources likevirus signature database serversandpatch servers, preventing users from accessing business services while allowing problem resolution.
* Position 3 # After successful authenticationAfter authentication succeeds, users enter thepost- authentication domain. At this stage, full or role-based access is granted to enterprise resources such as office data,R&D data,marketing systems, as well asintranet or Internet services, based on assigned policies.
This mapping reflects Huawei's standardNAC domain-based access control model, ensuring secure, staged network access.

(Huawei iMaster NCE-Campus provides the financial SD-WAN SRv6 solution to help the financial industry implement end-to-end scheduling. To use this function, you need to obtain the SRv6 function package license.)
- A. TRUE
- B. FALSE
Answer: A
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 advanced networking solutions tailored for industry-specific scenarios, including thefinancial SD-WAN SRv6 solution. This solution leverages Segment Routing over IPv6 (SRv6) to enable precise traffic steering, deterministic forwarding, and end-to-end service scheduling across the network.
Because SRv6 introduces enhanced forwarding capabilities and control-plane features beyond standard campus networking functions, Huawei licenses these capabilities separately. To activate SRv6-based financial SD-WAN features on iMaster NCE-Campus, customers must obtain theSRv6 function package license.
Without this license, SRv6-specific orchestration, scheduling, and optimization functions cannot be enabled.
According to HCIP Datacom Campus Network documentation, licensing ensures controlled feature activation and aligns with Huawei's modular service enablement strategy. Therefore, the statement is TRUE, and option A is correct.
