Airflow Design in Data Center Switches:

Airflow design is critical for efficient heat dissipation in data center switches. Front-to-back airflow ensures that cool air enters from the front and hot air exits from the back, aligning with typical data center cooling systems.

Huawei Cloud Engine S12700E:

The S12700E series switches are designed with front-to-back airflow to improve heat dissipation efficiency. This design minimizes overheating risks and ensures stable operation in high-density environments.

Conclusion:The statement is TRUE because the S12700E series uses a front-to-back airflow design.

Huawei'sdata center autonomous driving networkis classified asL3: conditional autonomous network. This level represents a significant advancement in network automation, where the system can handle most tasks autonomously but still requires human oversight for complex or exceptional scenarios.The levels of autonomous driving networks are defined as follows:

L0:Fully manual operations with no automation.

L1:Basic automation with assisted O&M tools.

L2:Partial autonomy, where some tasks are automated.

L3:Conditional autonomy, enabling self-driving capabilities under specific conditions.

L4:High autonomy, capable of handling nearly all tasks without human intervention.

Huawei's L3 implementation ensures efficient and reliable operations while maintaining flexibility for human intervention when needed.

The transition to all-Ethernet data center networks is driven by several IT transformations. Below is an analysis of each option:

PCIe is replaced : PCIe is a local bus standard used for high-speed device connections within servers. Its replacement does not directly contribute to the shift toward all-Ethernet networks.

Storage media evolves from HDDs to SSDs : The adoption of SSDs increases storage performance and reduces latency, making Ethernet-based storage protocols like NVMe over Fabrics (NVMe-oF) viable alternatives to traditional Fibre Channel.

The IT architecture evolves from centralized to distributed : Distributed architectures require scalable and flexible networking solutions, which Ethernet-based networks are well-suited to provide.

The deployment mode evolves from single-cloud mode to multiple deployment modes such as multi-cloud mode : While multi-cloud deployments influence network design, they do not directly drive the shift to all-Ethernet networks.

Thus, the correct answers are B and C .
