Huawei H12-891_V1.0 Exam With Confidence Using Practice Dumps

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

Ethernet Segment Identifier (ESI) is a 10-byte identifier used in EVPN (Ethernet VPN) to uniquely identify an Ethernet segment across a network, particularly in multi-homing scenarios. It ensures loop prevention and redundancy.

Exact Extract - HCIE-Datacom EVPN Section:

“The ESI is a 10-byte identifier and must be unique across the entire EVPN network. It plays a key role in identifying Ethernet segments in multi-homed environments.”

ForSRv6 (Segment Routing over IPv6)deployment on abearer WAN, the following are essential:

IGP (OSPFv3 or IS-IS): Required for SID advertisement and SRv6 route computation →✅

BGP: Required when deployinginter-domain SRv6or for control plane distribution of VPN/service routes →✅

Not required:

MPLS: SRv6 replaces MPLS labels withIPv6-based SIDs→❌

BGP-LU: Used inMPLS-based inter-AS scenarios,not applicableto SRv6 →❌

Correct answers: B, C
