Data center networks need to be scalable and efficient to connect tens or even hundreds of thousands of servers to handle the growing demands of cloud computing.
Correct Answer:
A
Moderndata center networksrequirehigh scalability and efficiencyto handle cloud computing workloads. Key requirements include:
Support for large-scale server connectivity(tens or hundreds of thousands of servers). High-bandwidth networking(100G/400G Ethernet links).
Automated network managementusing AI-driven controllers likeiMaster NCE-Fabric. Software-Defined Networking (SDN)for dynamic traffic optimization. Reference:HCSA-Presales-IP Network Official Study Guide, Data Center Network Architecture
Huawei's data center autonomous driving network sits at which level?
Correct Answer:
D
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.

Fat APs need to work with an AC, which is costly to deploy. Managed and configured by the AC in a unified manner, fat APs provide various functions and have high requirements on networkmaintenance personnel's skills.
Correct Answer:
B
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.

What are the three types of resources connected to the data center network?
Correct Answer:
ABC
In adata center network, three primary types of resources are connected: Storage:Includes storage arrays and systems that provide data persistence and retrieval capabilities.
High-performance computing (HPC):Supports compute-intensive workloads like scientific simulations and AI training.
General-purpose computing:Handles everyday workloads such as web hosting, application servers, and virtual machines.
These resources are interconnected through the data center network, enabling seamless communication and resource sharing. Each type serves a distinct purpose, catering to different application requirements.
