H12-841_V1.5 Exam Dumps : HCIP-Datacom-Campus Network Planning and Deployment V1.5

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.

In a CloudCampus virtualized campus network,Virtual Networks (VNs)provide service isolation, whilesecurity groupsenable identity-based access control. Even when inter-VN routing is technically available, communication between users in different VNs isnot permitted by default. Access permissions are controlled bysecurity group–based policies.

To allowR&D personnel and sales personnelto communicate, the network administrator must explicitly define thesecurity policy relationshipbetween the two security groups. This is achieved by deploying apolicy control matrixon iMaster NCE-Campus. The policy control matrix specifies whether traffic between source and destination security groups is allowed or denied and enforces the policy on relevant network devices.

Deploying an external network is unnecessary because communication is required within the campus network. Configuring access management relates to authentication and authorization during network access, not inter-group communication control. Configuring inter-VN communication enables routing capability but does not definewhethercommunication is permitted at the security policy level.

According to HCIP Datacom Campus Network documentation,security group communication permissions are controlled through the policy control matrix, making optionAthe correct task to meet the requirement.

1 →dh group1

2 →main

3 →esp

4 →tunnel

In the IKE proposal, the Diffie-Hellman group defines the key exchange strength used during IKE Phase 1 negotiation, which is whydh group1corresponds to position 1 under the IKE proposal configuration. Theexchange-mode mainsetting is part of IKEv1 Phase 1 and therefore correctly matches position 2 under the IKE peer configuration.

For the IPsec proposal, thetransformspecifies the protocol used to protect data traffic; since ESP is explicitly required,espcorrectly maps to position 3. Finally, theencapsulation-mode tunneldefines how packets are encapsulated in IPsec VPNs between gateways, makingtunnelthe correct match for position 4.

This mapping strictly follows HCIP Datacom Campus Network IPsec and IKE configuration logic and aligns with standard Huawei VRP command behavior.
