H12-891_V1.0 Exam Dumps : HCIE-Datacom V1.0

FEC (Forwarding Equivalence Class) in MPLS is a group of packets that are forwarded in the same manner. MPLS can classify packets into FECs based on factors such as:

Destination IP address

Source address

CoS (Class of Service)

Application type

However, Fragment Offset, which is part of the IP header used for IP fragmentation, is not used in FEC classification. Fragment offset is more relevant to how IP packets are reconstructed and not suitable or used as a classification standard for forwarding decisions in MPLS.

Exact Extract - Huawei HCIE-Datacom V1.0 MPLS Chapter:

“FEC classification may be based on various parameters including destination address, source address, and even CoS values. However, fragment offset is not used as an FEC criterion, as MPLS forwarding occurs before IP reassembly.”

An IPsec Security Association (SA) includes the following critical components:

SPI (Security Parameter Index)

Destination IP address

Security Protocol (AH or ESP)

Encryption/Authentication algorithms

The Source IP address is not a defining parameter of an SA. SA is unidirectional and identified based on the SPI and destination address.

Exact Extract - Huawei Security Configuration Guide – IPsec Fundamentals:

“An SA is uniquely identified by the SPI, destination IP, and security protocol. The source address is not a determining factor in the SA.”

Huawei iMaster NCE-Campus as an Authentication Relay Agent

Huawei iMaster NCE-Campus can act as a relay agent for authentication services, forwarding authentication requests between users and authentication servers (e.g., RADIUS, LDAP).

✅ B. User Authentication

Validates user credentials before granting network access.

Supports 802.1X, Portal, MAC, and RADIUS authentication.

✅ C. User Analysis

Analyzes user behavior and access patterns to optimize security and network policies.

✅ D. Marketing

Provides customized authentication portals with advertisements and promotional messages.

Incorrect Answer:

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