NQA on Huawei devices is designed to actively measure network performance by simulating service traffic and monitoring protocol behavior. It supports commonconnectivity and routing-related protocolsto detect delay, jitter, packet loss, and reachability.

NQA supportsICMP, which is widely used to test network connectivity and latency, makingoption D correct. It also supportsrouting protocol detection, including OSPF, enabling administrators to monitor routing convergence and path availability, validatingoption A.

DHCP and SNMP are management and configuration protocols rather than traffic or routing performance protocols. NQA does not actively simulate or monitor DHCP address allocation behavior or SNMP management communication, makingoptions B and C incorrect.

Thus, NQA focuses on traffic forwarding and routing health rather than control-plane management protocols.

Administrator:

– Defining a Security Group

– Defining a Policy Control Matrix

iMaster NCE-Campus:

– Delivering IP-Group Entries

– Delivering a Policy Control Matrix

In Huawei’s free mobility solution, responsibilities are clearly divided betweenadministratorsandiMaster NCE-Campusto achieve centralized control with automated policy delivery. Administrators are responsible forpolicy and security intent definition, while iMaster NCE-Campus handlesautomatic distribution and enforcement coordination.

Administrators firstdefine security groups, which represent logical user or terminal categories such as employees, guests, or IoT devices. These security groups form the basis of identity-based access control in the campus network. Administrators alsodefine the policy control matrix, which specifies communication permissions between different security groups, such as allow, deny, or redirect. This step represents business intent and security requirements and must be manually planned and configured.

Once these definitions are complete,iMaster NCE-Campus takes over the execution phase. It automaticallydelivers the policy control matrixto authentication points and policy enforcement points, translating high-level policies into device-level configurations. This ensures consistent policy enforcement across the entire campus network.

In addition, iMaster NCE-Campus automaticallydelivers IP-group entries, which bind user IP addresses to security groups. These entries are dynamically generated based on authentication results and are distributed to relevant devices so that traffic can be correctly identified and controlled as users move.

This division of labor aligns with HCIP Datacom Campus Network design principles, enabling simplified administration, reduced manual configuration, and truly seamless free mobility across the campus network.

Huawei’s free mobility solution is based onsecurity group–based policy control. In this architecture, users are dynamically associated with security groups after authentication. These security group identifiers are thencarried in user trafficas metadata when packets traverse the campus network.

When traffic reaches apolicy enforcement device, such as an edge node or border node, the device does not rely on traditional attributes like IP address, MAC address, or port number to make forwarding decisions. Instead, it extracts thesource and destination security group informationembedded in the traffic and matches it against the security policy matrix configured on the controller.

This mechanism enables identity-based and location-independent access control. Even if a user moves to a different access point or changes an IP address, the same security policies continue to apply as long as the user remains in the same security group. This is the core advantage of free mobility in Huawei campus networks.

Port numbers, MAC addresses, and IP addresses are traditional Layer 2 and Layer 3 identifiers, but they do not provide sufficient context for identity-based policy enforcement. According to HCIP Datacom Campus Network documentation, security group information is the key attribute used for policy lookup and enforcement in free mobility solutions. Therefore, option A is correct.
