Huawei IPsec supports multiple modes for establishing Security Associations (SAs):

A. Template negotiation — Used in IPsec policy templates and dynamic VPNs.

B. IKE auto-negotiation mode — Automatically negotiates parameters via IKE Phase 1/2.

C. Certificate negotiation — IPsec peers can authenticate each other using certificates during IKE negotiation.

D. Manual mode — Static IPsec SAs can be manually configured without IKE, often used in simple or static topologies.

Exact Extract - Huawei Security Configuration Guide (USG Series):

“IPsec SAs can be established manually or dynamically through IKE, including using PSKs or certificates. Template-based approaches simplify large-scale deployment.”

Huawei’sNQA (Network Quality Analysis)provides tools to test and monitor network performance such as latency, jitter, and packet loss. The supported test types include:

ICMP— For reachability and round-trip time testing.

UDP,TCP,HTTP,FTP, etc.

DNS,VoIP,DHCP(limited to simulation, not monitoring protocol status itself)

Protocols likeSNMPandOSPFarenot directly monitored by NQA, as these aremanagement or control plane protocols, not data-path or performance-measurable protocols.

Correct answer: C. ICMP

Huawei iMaster NCE-Campus as an Authentication Relay Agent

HuaweiiMaster NCE-Campuscan act as arelay agentfor authentication services, forwarding authentication requests between users and authentication servers (e.g., RADIUS, LDAP).

✅B. User Authentication

Validates user credentialsbefore granting network access.

Supports802.1X, Portal, MAC, and RADIUS authentication.

✅C. User Analysis

Analyzes user behavior and access patternsto optimize security and network policies.

✅D. Marketing

Providescustomized authentication portalswithadvertisements and promotional messages.

Incorrect Answer:

❌A. User Accounting–Accounting is handled by the authentication server (e.g., RADIUS), not the relay agent.
