At ValidExamDumps, we consistently monitor updates to the Huawei H19-301_V3.0 exam questions by Huawei. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Huawei HCSA-Presales-IP Network Certification V3.0 exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Huawei in their Huawei H19-301_V3.0 exam. These outdated questions lead to customers failing their Huawei HCSA-Presales-IP Network Certification V3.0 exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Huawei H19-301_V3.0 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Which of the following statements is TRUE about AirEngine products?
Huawei'sAirEngineseries includes a range of Wi-Fi 6 APs with varying capabilities:
AirEngine 5762-12:Supports a maximum device rate of2.975 Gbps, not 1.775 Gbps, making option A incorrect.
AirEngine 6761-21:Supports a maximum device rate of3.55 Gbps, making option B correct.
AirEngine 5762-12SW:Does support the leader AP feature, making option C incorrect.
AirEngine 5761-11:Does not have 2.5GE ports, making option D incorrect.
TheAirEngine 6761-21stands out for its high performance, making it suitable for demanding environments like large enterprises and campuses.

Which of the following controllers supports unified LAN-WAN management?
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.

Unlike managing a device through a console port, managing a device through Telnet does not require connecting to the device with a cable. The only requirement is that the Telnet client has a reachable address and can communicate with the Telnet service port of the device. Which kind of address should the client have?
Understanding Telnet:Telnet is a protocol used for remote management of networkdevices. Unlike console port management, which requires a physical connection, Telnet operates over the network.
Address Requirement:For Telnet communication to occur, the client must have an IP address. This is because Telnet relies on the TCP/IP protocol suite, and communication is established using IP addresses.
Why Not Other Options?
VLAN:A VLAN (Virtual Local Area Network) is a logical segmentation of a network but does not directly represent an address for communication.
AS:An Autonomous System (AS) is a collection of IP networks under a single administrative domain, not an address type.
MAC:A MAC address is a hardware identifier used at Layer 2 of the OSI model. While important for local network communication, it is not sufficient for Telnet, which operates at Layer 3.
Conclusion:The correct answer is IP, as it is the fundamental addressing scheme required for Telnet communication.

Fat APs need to work with an AC, which is costly to deploy. Managed and configured by the AC in a unified manner, fat APs provide various functions and have high requirements on networkmaintenance personnel's skills.
The statement contains several inaccuracies. Fat APs (Autonomous Access Points) are standalone devices that do not require a Wireless Access Controller (AC) to function. They are fully capable of managing their own configurations and operations independently.In contrast,Fit APs(Lightweight Access Points) rely on a centralized AC for management and configuration. While Fit APs offer centralized control and scalability, they require the deployment of an AC, which can increase costs. Fat APs are simpler to deploy in small-scale networks but may lack the advanced features and scalability of Fit APs.
The claim that Fat APs 'need to work with an AC' is incorrect, making the entire statement false.

Which of the following campus network challenges are enterprises facing as they move towards the all-cloud era?
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.
