The device's MAC address table specifications are greatly challenged by the rapidly increasing number of VMs. In order to solve this problem, we can use VXLAN with large- scale scalability. In a VXLAN scenario, which Huawei model can we propose?
Correct Answer:
A
VXLAN (Virtual Extensible LAN) is a network virtualization technology that addresses the limitations of traditional VLANs and MAC address tables by enabling large-scale Layer 2 networks over Layer 3 infrastructure. It is particularly useful in data centers with a growing number of virtual machines (VMs).
Among the options provided:
CE6881 : This switch supports VXLAN and is designed for high-density data center environments. It provides excellent scalability and performance for VXLAN-based networks, making it the most suitable choice.
CE9860 : While this switch is a high-end model, it is primarily used for core or aggregation layers and may not be the best fit for VXLAN at the access layer.
CE6820 : This switch does not support VXLAN, making it unsuitable for the scenario. CE5882 : This is an older model and lacks the advanced features required for modern VXLAN deployments.
Thus, the correct answer is A , as the CE6881 is the most appropriate model for VXLAN scenarios.

Huawei S5735-L series switches differ from Huawei S5731-S series switches in whether theysupport subcard expansion ports.
Correct Answer:
A
Comparison of S5735-L and S5731-S Series Switches:
Both series belong to Huawei's campus switch portfolio but target different use cases and have distinct features.
Subcard Expansion Ports:
S5735-L Series:These switches donotsupport subcard expansion ports. They are designed for fixed configurations and are suitable for small to medium-sized networks.
S5731-S Series:These switchesdosupport subcard expansion ports, allowing for greater flexibility in terms of port types and densities. This makes them ideal for larger or more complex networks.
Conclusion:The statement is TRUE because the S5735-L series lacks subcard expansion ports, while the S5731-S series supports them.

Which of the following are the hardware characteristics of the S8700?
Correct Answer:
ABCD
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.
