As more and more enterprise DCNs step into the AI era, more and more spine switch port bandwidth upgrades to 400G from 100G and leaf switch port bandwidth upgrades to 25G from 10G. If the customer requires the 25G TOR switch, which Huawei model can we propose?
Correct Answer:C
Huawei'sCloudEngine series switchesare designed to meet the evolving demands of modern data center networks (DCNs). For customers requiring25G Top-of-Rack (TOR) switches, theCE6881is the ideal choice.Key details about the models mentioned:
CE6820:A lower-end switch that does not support 25G ports. CE6870:Primarily supports 10G and 40G ports, not 25G.
CE6881:Specifically designed for 25G access and 100G uplinks, making it suitable for AI- era DCNs.
CE6863E:Focuses on high-density 100G/400G switching, not 25G TOR requirements. TheCE6881aligns perfectly with the need for 25G TOR switches, enabling higher bandwidth and scalability for AI and cloud workloads.

Which of the following statements are TRUE about fixed ports and cards of AR routers?
Correct Answer:ABC
Huawei'sAR routersoffer flexible configurations for fixed ports and modular cards, enabling them to adapt to various networking scenarios. Key points include:
LAN-to-WAN switching:LAN ports can be converted to WAN ports using theundo portswitchcommand, allowing greater flexibility in network design.
WAN-to-LAN switching:Some AR router models support converting WAN ports to LAN ports, depending on the hardware and software capabilities.
Layer 2 card limitations:Layer 2 cards configured with VLANIF interfaces can perform basic Layer 3 forwarding but lack advanced features like NAT, MPLS, IPsec, and HQoS.
The claim thatall Layer 2 cards support LAN/WAN switchingis incorrect. Only specific models and configurations support this functionality, making option D false. References:
