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

Geographic Redundancy in SD-WAN Controllers:

Huawei's SD-WAN solution provides geographic redundancy to ensure high availability and disaster recovery.

Analysis of Each Statement:

Option A:This is correct. The active and standby clusters share the same domain name or IP address, enabling seamless failover during an active/standby switchover.

Option B:This is correct. Geographic redundancy requires the active and standby clusters to have the same number of nodes to ensure balanced performance.

Option C:This is correct. Huawei's SD-WAN solution supports only one active cluster and one standby cluster for geographic redundancy.

Option D:This is incorrect. While the active and standby clusters synchronize data in real time, only the active cluster provides services. The standby cluster remains idle until a failover occurs.

Conclusion:The FALSE statement is Option D.

MACsec (Media Access Control Security) is a Layer 2 encryption protocol that ensures secure communication between devices in a network. It provides data confidentiality, integrity, and replay protection at the Ethernet layer.

The following models in the Huawei CloudEngine S6730 series support MACsec:

S6730-H48X6C : This switch supports MACsec on its high-speed ports, ensuring secure communication for critical applications.

S6730-H24X6C : Similar to the H48X6C, this model also supports MACsec, making it suitable for environments requiring robust security.

S6730-H24X4Y4C : This model also includes MACsec support, providing advanced security features for enterprise networks.

However, the S6730-S24X6Q does not support MACsec. It is designed for scenarios where Layer 2 encryption is not a primary requirement.

Thus, the correct answers are A , B , and D .

HuaweiWLAN solutionssupport multiple networking modes to adapt to different enterprise requirements:

(A) Independent Fat AP Networking (True):Each AP operatesindependentlywithout a Wireless Access Controller (WAC). Suitable forsmall-scale networks.

(B) Cloud Management Networking (True):UsesHuawei CloudCampusto manage APs remotely viaiMaster NCE-Campus. Ideal forlarge, multi-branch enterprises.

(C) WAC + Fit AP Networking (True):CentralizedWAC (Wireless Access Controller)managesFit APs, optimizing performance and security.

(D) AC-Free Self-Networking of the Leader AP (True):Aleader APacts as a mini-controller, managing other APs without a WAC. Used insmall to medium networks.

Huawei firewalls come preconfigured with several default security zones, each serving a specific purpose:

DMZ (Demilitarized Zone):A buffer zone between the internal network and external networks, often used to host public-facing servers like web servers.

Local:Represents the firewall itself. Traffic destined for the firewall (e.g., management traffic) is associated with this zone.

Untrust:Represents external, untrusted networks such as the Internet. Security policies typically restrict traffic from this zone.

Trust:Represents internal, trusted networks. Traffic within this zone is generally considered safe.

These zones form the foundation of firewall security policies, allowing administrators to control traffic flows between different parts of the network.

TCP (Transmission Control Protocol) is a connection-oriented protocol with several key characteristics:

Connectionless : This is not a characteristic of TCP. TCP establishes a connection before transmitting data using a three-way handshake.

Flow control and window mechanism : TCP uses flow control and sliding window mechanisms to manage data transmission rates and prevent buffer overflow.

Connection-oriented : TCP establishes, maintains, and terminates connections between endpoints.

Reliable transmission : TCP ensures reliable delivery of data through acknowledgments, retransmissions, and error detection.

UDP, not TCP, is a connectionless protocol. Therefore, the correct answer is A .

TheS5731-HandS5731-Sare part of Huawei's CloudEngine S series switches, but they differ in their software capabilities. Specifically:

S5731-H:Supports advanced features likeVXLAN (Virtual Extensible LAN), which enables network virtualization and scalable overlay networks.

S5731-S:Lacks VXLAN support, making it suitable for simpler deployments without virtualization requirements.

This distinction is critical when selecting switches for environments that require advanced virtualization and cloud integration.

Overview of Huawei CloudFabric Easy Solution:

Huawei CloudFabric Easy Solution is designed to simplify data center networking through automation, ease of use, and scalability. Its key highlights are summarized under the acronym "EASY."

Explanation of Each Highlight:

EasY-Maintenance:The solution simplifies network operations and maintenance, reducing complexity and operational costs.

Expandability:While expandability is important, it is not one of the four "EASY" highlights explicitly mentioned in the official documentation.

Simplification:The solution focuses on simplifying network deployment, configuration, and management.

Easy Sales:This is not part of the "EASY" highlights. The term refers to technical benefits rather than sales processes.

Automation:The solution leverages automation to streamline tasks such as provisioning, monitoring, and troubleshooting.

Conclusion:The four highlights of Huawei CloudFabric Easy Solution are EasY-Maintenance, Simplification, and Automation.

Overview of Huawei CloudCampus 3.0:

Huawei CloudCampus 3.0 is designed to provide a fully-wireless, intelligent, and cloud-based campus network solution. It focuses on improving efficiency, reducing costs, and enabling digital transformation.

Analyzing Each Option:

Option A:"One global network: 40% lower private line costs" is correct. Huawei CloudCampus 3.0 reduces private line costs by leveraging cloud-based technologies and SD-WAN solutions.

Option B:"L3 autonomous driving: 90% fewer complaints" is correct. The solution uses AI-driven automation to minimize network issues and improve user satisfaction.

Option C:"Low-carbon intelligence: 60% smaller energy consumption of the entire network" isnot correct. While Huawei emphasizes energy efficiency, the claim of a 60% reduction in energy consumption is exaggerated and not supported by official documentation.

Option D:"Fully-wireless experience: 40% higher productivity" is correct. The fully-wireless architecture enhances user experience and productivity.

Conclusion:The incorrect benefit description is Option C.

Huawei's L3 autonomous driving solution leverages AI and automation to enhance network performance through intelligent O&M. Below is an explanation of each capability:

Intelligent HQoS : Hierarchical Quality of Service (HQoS) ensures optimal resource allocation for critical applications. Intelligent HQoS dynamically adjusts policies based on real-time traffic conditions, improving application performance and user experience.

Intelligent network optimization : AI-driven algorithms analyze network traffic patterns and optimize routing, bandwidth allocation, and load balancing to maximize efficiency and reduce latency.

Real-time experience visualization : Visualization tools provide real-time insights into network performance and user experience. This enables administrators to quickly identify bottlenecks and take corrective actions.

Precise fault analysis : Advanced diagnostics and AI-powered analytics pinpoint the root cause of network issues with high accuracy, enabling faster troubleshooting and resolution.

All four options represent key capabilities of Huawei's intelligent O&M solution.

Wired and wireless convergence is a key trend in modern campus networks, enabling unified management and seamless connectivity across wired and wireless devices. Huawei switches equippedwithWireless Access Controller (WAC) cardsintegrate wired and wireless functions into a single platform. This integration provides:

Hardware-level convergence:Combines switching and wireless control capabilities in one device.

Software-level convergence:Enables centralized management, policy enforcement, and traffic optimization for both wired and wireless networks.

This approach simplifies network architecture, reduces costs, and improves operational efficiency, making it a preferred solution for converged campus networks.
