H19-301_V3.0 Practice Exam Questions and Answers

Managing a large number of branches in an enterprise WAN environment presents several challenges. Below is an analysis of each option:

Difficulties in rectifying faults on branch networks : With numerous branches, identifying and resolving network faults becomes complex, especially when relying on manual troubleshooting.

Long time to provision new services in branches : Deploying new services across multiple branches requires significant coordination and configuration effort, leading to delays.

Poor experience with key applications : Limited bandwidth, high latency, and inefficient traffic steering can degrade the performance of critical applications like video conferencing and ERP systems.

High O&M costs : Managing distributed branch networks involves substantial operational and maintenance costs, including personnel, tools, and infrastructure expenses.

All four options accurately describe the challenges faced in enterprise WAN interconnection with large numbers of branches.

Huawei's IoT-enabled Wi-Fi 6 APs integrate wireless networking with IoT capabilities, enabling converged solutions for various industries. Let us evaluate each statement:

Currently, IoT expansion is only available for RFID and Bluetooth protocols : This is false . While RFID and Bluetooth are common IoT protocols, Huawei's IoT-enabled APs support additional protocols like Zigbee and LoRa, depending on the model.

IoT expansion can be implemented through PCIe cards or USB ports : This is true . Huawei APs support IoT expansion modules that can be connected via PCIe cards or USB ports, enabling flexible integration of IoT functionalities.

Radios used by IoT and Wi-Fi do not transmit on the same channel, so there is no need to consider interference between IoT and Wi-Fi signals : This is false . Depending on the frequency bands used, IoT and Wi-Fi signals may interfere with each other. Proper planning and configuration are required to minimize interference.

The outdoor Wi-Fi 6 AP AirEngine 5761R-11 supports IoT expansion : This is true . The AirEngine 5761R-11 is an outdoor AP that supports IoT expansion, making it suitable for scenarios like smart cities and industrial IoT.

Thus, the correct answers are B and D .

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.

Understanding the Network Layer:

The network layer (Layer 3 of the OSI model) is responsible for end-to-end packet delivery, including routing and addressing. Protocols operating at this layer handle logical addressing and path determination.

Explanation of Each Protocol:

IPv6:The next-generation Internet Protocol, which operates at the network layer to provide addressing and routing for packets.

ICMPv6:Internet Control Message Protocol version 6, used for error reporting and diagnostic functions in IPv6 networks. It operates at the network layer.

IPv4:The current widely-used Internet Protocol, which operates at the network layer to provide addressing and routing for packets.

OSPF:Open Shortest Path First is a dynamic routing protocol that operates at the network layer to exchange routing information between routers.

ICMP:Internet Control Message Protocol, used for error reporting and diagnostic functions in IPv4 networks. It operates at the network layer.

Conclusion:IPv6, ICMPv6, IPv4, and ICMP all operate at the network layer. OSPF is also correct because it is a routing protocol that works at Layer 3.
