MACsec (Media Access Control Security) is a Layer 2 encryption protocol that ensures secure communication between devices in a network. It provides data confidentiality, integrity, and replay protection at the Ethernet layer.

The following models in the Huawei CloudEngine S6730 series support MACsec:

S6730-H48X6C : This switch supports MACsec on its high-speed ports, ensuring secure communication for critical applications.

S6730-H24X6C : Similar to the H48X6C, this model also supports MACsec, making it suitable for environments requiring robust security.

S6730-H24X4Y4C : This model also includes MACsec support, providing advanced security features for enterprise networks.

However, the S6730-S24X6Q does not support MACsec. It is designed for scenarios where Layer 2 encryption is not a primary requirement.

Thus, the correct answers are A , B , and D .

The Huawei CloudEngine S12700E series is a high-end modular switch designed for enterprise campus networks. Below are the explanations for each highlighted feature:

Ultra-large buffer and HQoS scheduling, delivering optimal user experience of key applications : The S12700E series features a large buffer and advanced Hierarchical Quality of Service (HQoS) scheduling, ensuring smooth performance for critical applications even under heavy traffic conditions.

Powerful slot forwarding capability, building Wi-Fi 6 high-speed channels : The switch supports high-speed forwarding capabilities, making it ideal for supporting Wi-Fi 6 networks and handling the increased bandwidth demands of modern applications.

Control and switching separation, on-demand configuration, and flexible capacity expansion : The S12700E adopts a control-switching separation architecture, allowing users to configure resources on demand and expand capacity flexibly as needed.

Redundancy design for key components, ensuring 99.999% reliability : The switch includes redundant power supplies, fans, and control boards, ensuring high availability and reliability for mission-critical environments.

All four options are valid highlight features of the CloudEngine S12700E series.

TheUSG6000E-Bfirewall doesnotsupport hardware bypass by default. If hardware bypass functionality is required, anexternal bypass devicemust be purchased and configured.Hardware bypass ensures network continuity in case of a firewall failure by physically rerouting traffic around the device. Since this feature is not included by default in the USG6000E-B, additional hardware is necessary to achieve it.

"One-click fast scheduling, cloud-network coordinated scheduling" refers to the ability to provision services quickly and efficiently using advanced technologies like SRv6 (Segment Routing over IPv6) . This feature enables agile service rollout by automating the configuration and deployment of network services across cloud and WAN environments. With SRv6, services can be provisioned within minutes, significantly reducing the time required for manual configuration and ensuring rapid adaptation to changing business needs.

The other options describe different features of Huawei's solutions but do not directly align with the concept of "one-click fast scheduling." For example:

Option B refers to network diagnostics and troubleshooting capabilities.

Option C highlights resource optimization through SDN and intelligent algorithms.

Option D focuses on network slicing, which is a separate feature for enhancing network flexibility.

Thus, the correct answer is A , as it directly addresses the concept of fast and coordinated scheduling in cloud-network environments.
