H19-301_V3.0 Exam Dumps - Huawei HCPA-IP Network Questions and Answers

VXLAN (Virtual Extensible LAN) is a network virtualization technology that addresses the limitations of traditional VLANs and MAC address tables by enabling large-scale Layer 2 networks over Layer 3 infrastructure. It is particularly useful in data centers with a growing number of virtual machines (VMs).

Among the options provided:

CE6881 : This switch supports VXLAN and is designed for high-density data center environments. It provides excellent scalability and performance for VXLAN-based networks, making it the most suitable choice.

CE9860 : While this switch is a high-end model, it is primarily used for core or aggregation layers and may not be the best fit for VXLAN at the access layer.

CE6820 : This switch does not support VXLAN, making it unsuitable for the scenario.

CE5882 : This is an older model and lacks the advanced features required for modern VXLAN deployments.

Thus, the correct answer is A , as the CE6881 is the most appropriate model for VXLAN scenarios.

Huawei'sSD-WAN multi-fed and selective receiving technologyis not limited to5G links. This technology can be applied to various types of WAN links, including MPLS, Internet, LTE, and 5G, to optimize traffic steering and improve reliability.The multi-fed feature allows multiple links to be used simultaneously, while selective receiving ensures that the best path is chosen for each application based on real-time conditions. This flexibility makes the technology applicable across diverse network environments, not just 5G.

Overview of Audio and Video Service Assurance:

Huawei provides advanced mechanisms to ensure high-quality audio and video services in wireless networks, even under congestion.

Analysis of Each Statement:

Option A:This is incorrect. The correct default priority order isVI -> VO -> BE -> BK(Voice > Video > Best Effort > Background).

Option B:This is correct. Beacon frames can be used to instruct APs to suppress heavy-traffic users, ensuring fair resource allocation.

Option C:This is correct. Huawei's lab tests show that delays for voice and video services in congestion scenarios are56% lowerthan the industry average.

Option D:This is correct. The default scheduling priority order isVI -> VO -> BE -> BK.

Option E:This is incorrect. Heavy-traffic services are not automatically suppressed; suppression requires explicit configuration.

Conclusion:The correct statements are Options B, C, and D.

Huawei's CloudWAN solutions target various railway services and market opportunities. Below is an analysis of each option:

Integrated information network : This refers to the unified network infrastructure that integrates multiple railway systems, such as passenger information, ticketing, and security. It is a key focus area for Huawei routers.

Vehicle-ground communication network : This involves communication between trains and ground stations, enabling real-time monitoring, diagnostics, and control. It is a critical railway service supported by Huawei routers.

Interconnection load balancing between backbone clouds : This is more relevant to cloud data center interconnections rather than railway-specific services. It is not a primary focus for railway services.

Railway signal bearer network : This refers to the network that carries signaling and control information for safe train operations. It is a core railway service supported by Huawei routers.

Thus, the correct answer is C , as interconnection load balancing between backbone clouds is not directly related to railway services.

HuaweiiMaster NCE(Network Cloud Engine) is an intelligent network automation platform that integratesmanagement, analysis, and controlcapabilities, but it doesnot handle routing functions directly.

(A) Management – True: iMaster NCE provides centralizednetwork lifecycle management, including configuration, monitoring, and automation.

(B) Routing – False: Routing is handled by network devices like routers and switches, not by iMaster NCE itself.

(C) Analysis – True: The platform incorporatesbig data analyticsto provide network insights, fault prediction, and performance optimization.

(D) Control – True: iMaster NCE serves as anSDN controller, managing network policies, path selection, and automation.

The Huawei CloudEngine S8700 series switches are designed for enterprise campus networks and aggregation layers, offering advanced hardware features that ensure high performance, scalability, and reliability. Below is an explanation of each option:

Cards with ultra-high-density GE optical/GE electrical/10GE optical ports : The S8700 supports high-density interfaces, including Gigabit Ethernet (GE) and 10 Gigabit Ethernet (10GE) ports, making it suitable for large-scale campus networks.

Ultra-high PoE++ output capability, supporting ultra-long-distance high-performance PoE transmission : The switch provides Power over Ethernet (PoE++) support, delivering up to 90W per port. This capability is ideal for powering devices like IP cameras, wireless access points, and IoT devices over long distances.

Service subcards are integrated on the main control board panel, separating the forwarding plane from the control plane and enriching port combinations : This design enhances modularity and flexibility, allowing users to customize port configurations based on their specific requirements.

The main control boards work in 1:1 backup mode. When a main control board is removed and then installed, no packet loss occurs and the performance does not deteriorate : The S8700 ensures high availability through redundant main control boards. This feature guarantees uninterrupted operation even during maintenance or failures.

All four options accurately describe the hardware characteristics of the S8700, making them all correct.

To exchange routes between Autonomous Systems (ASs), BGP (Border Gateway Protocol) is used. BGP is specifically designed for inter-AS routing and supports scalable and policy-based route distribution across large networks.

Static routing : Requires manual configuration and is not scalable for large networks.

IS-IS and OSPF : These are Interior Gateway Protocols (IGPs) used for intra-AS routing, not inter-AS routing.

Thus, the correct answer is B , as BGP is the standard protocol for inter-AS route exchange.

Overview of S5731-L Remote Units (RUs):

The S5731-L series includes remote units (RUs) designed for distributed campus networks. These RUs connect to a central switch via uplink ports.

Uplink Port Flexibility:

The RUs supportoptical, electrical, and hybrid optical-electrical ports, allowing flexible selection based on the distance between the RU and the central switch.

Optical ports are used for long-distance connections, while electrical ports are suitable for shorter distances. Hybrid ports combine both options for maximum versatility.

Conclusion:The statement is TRUE because the S5731-L RUs support multiple uplink port types for flexible deployment.
