Free Huawei H12-891_V1.0 Exam Actual Questions

Note: Premium Questions for H12-891_V1.0 were last updated On Apr. 07, 2026 (see below)

Question #1

Free mobility implements policy management and permission control based on users' VLAN IDs and IP addresses.

Reveal Solution Hide Solution
Correct Answer: B

Why is Free Mobility Not Based on VLANs or IP Addresses?

Free mobility in Huawei CloudCampus implements policy-based user access control based on user identity (rather than VLANs or IP addresses).

Users can move across different network locations while maintaining their assigned security and access policies.

How Free Mobility Works:

Policies are applied based on User Groups instead of VLAN or IP.

Uses Group-Based Policy Control (GBP) and Software-Defined Access (SDA) principles.

Incorrect Statement

Traditional networks rely on VLANs and IP addresses for segmentation, but Free Mobility applies policies at the user level, allowing seamless access anywhere on the network.

Reference from Huawei HCIE-Datacom Documentation:

Huawei CloudCampus Solution Guide -- Free Mobility and Policy Control

HCIE-Datacom Training Material -- Identity-Based Networking


Question #2

What can be determined from the following IS-IS peer output?

Peer information for ISIS(1):

Peer System ID: ee8c.a0c2.baf3

Interface: GE0/0/0

State: Up

HoldTime: 7s

Type: L1

PRI: 64

MT IDs supported: 0(UP), 2(UP)

Local MT IDs: 0, 2

Area Address(es): 49.0022

Peer IP Address(es): 10.1.34.1

Peer IPv6 Address(es): FE80::2E0:FCFF:FE98:2576

Reveal Solution Hide Solution
Correct Answer: A

Comprehensive and Detailed

The IS-IS peer output shows:

IPv4 Peer Address: 10.1.34.1

IPv6 Peer Address: FE80::2E0:FCFF:FE98:2576

MT IDs (Multi-Topology) Supported: 0 (IPv4), 2 (IPv6)

Since both IPv4 and IPv6 peer addresses are listed, it confirms that both IPv4 and IPv6 IS-IS neighbor relationships are established between R4 and ee8c.a0c2.baf3.

Reference: Huawei HCIE Datacom -- IS-IS Multi-Topology Support


Question #3

When a Layer 3 switch sends IP packets originating from one VLAN to another LAN, which field in the following options is overridden?( Single choice questions).

Correct Answer: A

Question #4

By default, huawei firewalls provide the following security areas:
