Free Huawei H12-891_V1.0 Practice Exam with Questions & Answers | Set: 10

Comprehensive and Detailed Explanation:

On-premise moderefers to deploying theHuawei iMaster NCE-Campus controllerwithin the enterprise network instead of using a cloud-based solution.

✔Best suited forsmall and midsize campus networksthat require:

Greater control over data security

Local network automation

No reliance on cloud connectivity

Sinceon-premise mode is recommended for small and midsize campus networks, the statement isTRUE.

Understanding Network Monitoring Data Categories

????Network devices operate across three functional planes:

✅A. Management Plane:

Handlesdevice configuration, authentication, and monitoring.

Example:SNMP, SSH, NETCONF logs.

✅B. Data Plane (Forwarding Plane):

Handlespacket forwarding and switching.

Example:Interface statistics, traffic rates, dropped packets.

✅C. Control Plane:

Handlesrouting, signaling, and protocol operations.

Example:BGP, OSPF, and MPLS signaling messages.

❌D. Monitoring Plane (Incorrect Choice):

There is no "monitoring plane" in network architecture.

Monitoring tools collect data frommanagement, control, and data planes, butdo not form a separate plane.

Why is the Answer D (Monitoring-plane data)?

❌Monitoring-plane does not exist as a separate category in network architecture.

✅O&M tools collect data from management, control, and data planes, but do not define a separate "monitoring plane".

Real-World Application:

Huawei iMaster NCE-Campus & iMaster NCE-WANcollect real-timenetwork statistics and alarms.

Network Performance Monitoring (NPM)toolsanalyze control-plane eventsto detect failures.

Network migration typically includes the followingphases:

Preparation Phase:

Network survey

Migration plan design

Backup

Pre-configuration

Middle Phase (Migration Execution):

On-site monitoring

Migration implementation

Service test (to verify the migration effect)

Post-Migration Phase:

Optimization

Documentation

Final acceptance

Hence,Migration preparationis part of theinitial phase, not themiddle phase.

Correct answer: A. Migration preparation

Comprehensive and Detailed Explanation:

✔Thecorrect sequence of operations:

Download the file from remote device(/vrpcfg.cfg) → Store as C:\backup.cfg.

Upload the renamed file (backup.cfg) back to the remote device.

✔Breaking Down the Correct Option (B):

✅sftp.get('/vrpcfg.cfg', r'C:\backup.cfg')→ Downloads vrpcfg.cfg from the remote device and renames it backup.cfg in C:\.

✅sftp.put(r'C:\backup.cfg', '/')→ Uploads backup.cfg back to the remote device.

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.”
