Huawei HCSP-Presales-Data Center Network Planning and Design V1.0 Sample Questions:
1. Which of the following statements is false about M-LAG?
A) An M-LAG can be established between two devices of different types.
B) If the access device is single-homed to the M-LAG, the M-LAG does not deliver the unidirectional isolation configuration of the corresponding M-LAG member interface.
C) An interface configured as a peer-link interface cannot be configured with any other service.
D) A peer-link is a direct link and must be configured with link aggregation.
2. (Which of the following statements is false about the underlay and overlay networks?)
A) An overlay network is a logical network defined on a physical bearer network (underlay network).
B) The overlay and underlay networks must use the same routing protocol.
C) The devices (such as servers, VAS devices, and external routers) connected to NVEs are unaware of the underlay network.
D) Generally, the overlay network is implemented through VXLAN.
3. Which of the following is not an advantage of the distributed VXLAN gateway networking?
A) A single device does not need to learn the ARP entries of all servers, and the network scalability is improved.
B) A leaf node can function as both a Layer 2 VXLAN gateway and a Layer 3 VXLAN gateway, supporting flexible deployment.
C) Leaf nodes only need to learn the ARP entries of the servers connected to them, reducing resource consumption.
D) Inter-subnet traffic can be centrally managed, and gateway deployment and management are simple.
4. (What are the application scenarios of the overlay network?)
A) Public cloud service (IaaS/PaaS/SaaS)
B) Network NFV cloud (network cloud and SDN + NFV)
C) Private cloud (converged resource pool deployment and data center integration)
D) Hosting services in traditional IDCs
5. In the network virtualization scenario or during secondary orchestration in the cloud-network integration scenario, iMaster NCE-Fabric provides functions such as pre-event verification, simu-lation, and resource consumption estimation for service provisioning. These functions help users determine whether the service orchestration can achieve the expected effect, whether existing services will be affected, and how many device resources will be consumed.
A) TRUE
B) FALSE
