H19-301_V3.0 Exam Dumps - HCSA-Presales-IP Network Certification V3.0

Overview of Huawei Controllers:

Huawei offers a range of controllers under the iMaster NCE series, each designed for specific use cases.

Analysis of Each Controller:

iMaster NCE-Fabric:Focuses on data center network automation and management. It does not support unified LAN-WAN management.

iMaster NCE-WAN:Specializes in WAN management, particularly for SD-WAN solutions. It does not manage LANs.

iMaster NCE-Campus:Designed for campus networks, this controller supportsunified LAN-WAN management, enabling centralized control of both wired and wireless networks.

iMaster NCE-IP:Focuses on traditional IP/MPLS network management and does not support unified LAN-WAN management.

Conclusion:The correct answer is Option C, as iMaster NCE-Campus supports unified LAN-WAN management.

Huawei's wireless backhaul solution for rail transportation is designed to meet the unique demands of high-speed mobility and mission-critical communications. Key features include:

Low handover delay:Achieves handover delays as low as30 ms, ensuring seamless connectivity even at high speeds.

Active-active links:Provides highly reliable redundancy through active-active link configurations, minimizing downtime.

Support for train control systems:The solution can carry critical train control signals, ensuring safety and operational efficiency.

The claim that backhaul is unavailable at speeds of160 km/his incorrect. Huawei's solution supports reliable backhaul even at high speeds, making it suitable for modern high-speed rail networks.

HuaweiiMaster NCEis acentralized network management and control systemforSDN-capableandtraditionaldevices.

(A) True – SDN control via NETCONF/YANG:iMaster NCE usesNETCONF(based on theYANG model) to manage and controlSDN-enableddevices, automating configuration and policy enforcement.

(B) True – SNMP for traditional devices:Traditional network devices (non-SDN) are managed throughSNMP (Simple Network Management Protocol), which provides device monitoring and basic configuration.

(C) False – No direct control through CU (Control Unit):Huawei does not define aCUas an independent management entity in iMaster NCE. Instead, SDN-capable devices are controlled viaNETCONF/YANG, while traditional devices rely onSNMP.

Understanding Antenna Gain:

Antenna gain refers to the ability of an antenna to focus or direct radio frequency (RF) energy in a specific direction. Higher gain antennas provide stronger signals and extended coverage in the direction they are focused.

Impact on AP Selection:

In scenarios where long-range coverage or better signal strength is required, an AP with a higher antenna gain (within regulatory limits) is preferred.

However, it is important to ensure that the antenna gain complies with the regulatory requirements of the country where it is deployed.

Conclusion:The statement is TRUE because higher antenna gain improves signal strength and coverage, making such APs desirable for specific use cases.

Understanding Hardware-Based BFD:

Bidirectional Forwarding Detection (BFD) is a protocol used to detect faults in network paths quickly. Hardware-based BFD offloads processing to dedicated chips, enabling faster detection intervals.

Huawei CE6863E-48S6CQ Capabilities:

TheCE6863E-48S6CQswitch supports hardware-based BFD with aminimum packet sending interval of 3.3 ms, ensuring rapid fault detection and recovery.

Conclusion:The statement is TRUE because the CE6863E-48S6CQ supports hardware-based BFD with the specified interval.
