NEW QUESTION # 55
NetEco management system can automatically calculate the electricity cost of the computer room according to the tiered electricity price strategy.
Answer: A
NEW QUESTION # 56
(What are the application scenarios of the overlay network?)
Answer: A,B,C,D
Explanation:
Huawei data center design documents clearly state that overlay networks (typically based on VXLAN EVPN) are highly versatile and support multiple application scenarios across modern and traditional environments.
In private cloud scenarios , overlay networks enable resource pooling and seamless data center interconnection, allowing flexible workload migration and multi-tenant isolation. For traditional IDC hosting services , overlays provide improved scalability and tenant isolation compared to VLAN-based designs, making them suitable for legacy-to-cloud evolution.
In public cloud environments (IaaS/PaaS/SaaS) , overlay networks are essential for large-scale multi-tenancy, enabling logical network segmentation, automation, and elastic service provisioning. Similarly, in NFV cloud scenarios , overlays integrate with SDN and NFV architectures to support virtualized network functions, service chaining, and dynamic service deployment.
Huawei CloudFabric emphasizes that overlay technology is not limited to a single use case but is a foundational technology across all modern data center architectures. Therefore, all listed options are valid application scenarios.
NEW QUESTION # 57

Answer: B,D,E
NEW QUESTION # 59
In the CloudFabric Solution, firewalls can connect to service leaf nodes or border leaf nodes (combined with service leaf nodes).
Answer: A
Explanation:
In Huawei CloudFabric architecture, service integration and flexible deployment of security devices such as firewalls are key design principles. Firewalls can be deployed in multiple ways depending on service requirements, traffic patterns, and scalability considerations.
Firewalls can be connected to:
Service leaf nodes : These are dedicated nodes used for service insertion (e.g., firewall, load balancer). Traffic can be steered through these nodes using policy-based routing or service chaining.
Border leaf nodes (combined with service leaf role) : In some designs, border leaf nodes (which connect to external networks such as WAN or Internet) can also integrate service functions, including firewall connectivity. This reduces hardware requirements and simplifies deployment.
Huawei supports both centralized and distributed service deployment models , allowing firewalls to be flexibly inserted into the network fabric. Integration is typically achieved using VXLAN, EVPN, and service chaining technologies , ensuring seamless traffic steering and policy enforcement.
This flexibility enhances:
Network scalability
Security enforcement
Operational simplicity
Therefore, the statement is TRUE .
