Huawei Updated H19-301_V3.0 Exam Questions and Answers by mckenzie

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.

Understanding SRv6 Support in AR Routers:

SRv6 (Segment Routing over IPv6) is a next-generation networking technology that simplifies traffic engineering and improves scalability in WANs.

Analysis of Each Model:

AR6300:This high-end AR router supports SRv6, making it suitable for advanced SD-WAN and WAN deployments.

AR6140E:This model does not support SRv6.

AR8140:This model also does not support SRv6.

None of the above:This is incorrect because the AR6300 supports SRv6.

Conclusion:The correct answer is Option A, as the AR6300 supports SRv6.

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.
