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

Large and midsize campus networks face unique challenges due to their scale, diversity of devices, and evolving service demands. Below is an analysis of each option:

Unknown threats must be detected and contained to prevent intrusion and spread : Security is a top priority in campus networks. Advanced threat detection mechanisms, such as AI-driven analytics and sandboxing, are essential to identify and mitigate unknown threats before they impact the network.

Diversified access terminals and services are calling for a converged network : Modern campus networks must accommodate a wide range of devices (e.g., smartphones, IoT devices, laptops) and services (e.g., voice, video, data). A converged network architecture simplifies management and ensures seamless connectivity across all devices.

As applications and services surge, the network needs to be automated to address the deployment and policy complexity : Automation tools, such as SDN and intent-driven networking (IDN), help streamline network deployment and policy enforcement, reducing manual intervention and minimizing errors.

Network O&M needs to be automated and intelligent to perceive user experience anytime and anywhere : Intelligent O&M solutions leverage AI and machine learning to monitor network performance, predict issues, and optimize user experience in real time.

All four options accurately describe the service requirements of large and midsize campus networks.

Understanding iStack Technology:

iStack is Huawei's stacking technology that allows multiple switches to be managed as a single logical device. This simplifies network configuration, management, and troubleshooting.

Dedicated Stack Ports or Stack Cards:

To enable iStack functionality, Huawei switches require either dedicated stack ports or stack cards. These ports/cards facilitate high-speed interconnection between stacked switches.

Benefits of iStack:

Simplifies network topology by reducing the number of managed devices.

Enhances scalability and reliability through unified management.

Conclusion:The statement is TRUE because dedicated stack ports or stack cards are required to support iStack technology.

MPLS (Multiprotocol Label Switching) is a tunneling technology that enables fast, efficient data forwarding based on labels rather than traditional IP routing. It providesconnection-orientedforwarding using label-switched paths (LSPs), ensuring reliableQuality of Service (QoS).

(A) True– MPLS is connection-oriented and enhances QoS by predefining LSPs through traffic engineering.

(B) True– MPLS useslabel switching, eliminating the need for IP lookups at each hop, significantly improving forwarding efficiency.

(C) False– MPLS is not connectionless; rather, it establishes virtual circuits (LSPs) for traffic. It providesend-to-end QoSthrough traffic prioritization.

(D) True– Labels in MPLS can be eithermanually assignedordynamically allocatedusing protocols likeLDP (Label Distribution Protocol)orRSVP-TE.

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.

Overview of MOX Government Network Scenario:

MOX refers to government ministries and organizations requiring robust, scalable, and secure WAN solutions for their backbone networks.

Recommended Backbone Router:

TheNetEngine 8000 Xseries is specifically designed for high-capacity, high-reliability backbone networks. It supports advanced features like SRv6, FlexE, and large-scale routing, making it ideal for government WANs.

Conclusion:The correct answer is Option C, as the NetEngine 8000 X is the recommended backbone router for MOX scenarios.

Huawei'smulti-DC controllerenablesdistributed multi-cloud and multi-data center managementwith key capabilities:

(A) Hybrid Cloud Simulation and Verification (False):Huawei’s solution doesnotinclude full simulation capabilities but offersreal-time monitoring.

(B) Intelligent O&M (True):UsesAI-driven analyticsto providepredictive maintenanceandfault diagnosis.

(C) Three-Layer Network Visibility (True):Providesend-to-end visibilityat theinfrastructure, network, and service layers.

(D) Uniform Orchestration (True):Automatesnetwork resource allocationacross multiple data centers.

As enterprises transition to cloud-centric architectures, campus networks face several challenges:

Slow fault locating:Traditional networks lack intelligent tools for rapid fault detection and resolution, leading to prolonged downtime.

Wi-Fi discontinuous networking:Poorly designed wireless networks result in coverage gaps and inconsistent user experiences.

Cloud outpacing network:Cloud services evolve faster than traditional networks can adapt, creating bottlenecks.

Difficult network scaling:Legacy networks struggle to scale dynamically to meet growing demands.

Cross-domain fragile infrastructure:Fragmented management across domains (e.g., wired, wireless, WAN) leads to inefficiencies and vulnerabilities.

Addressing these challenges requires modern solutions like SDN (Software-Defined Networking), AI-driven O&M, and unified management platforms.
