Huawei HCSP-Presales-Data Center Network Planning and Design V1.0 Sample Questions:
1. Which of the following is not an advantage of the distributed VXLAN gateway networking?
A) Leaf nodes only need to learn the ARP entries of the servers connected to them, reducing resource consumption.
B) A single device does not need to learn the ARP entries of all servers, and the network scalability is improved.
C) A leaf node can function as both a Layer 2 VXLAN gateway and a Layer 3 VXLAN gateway, supporting flexible deployment.
D) Inter-subnet traffic can be centrally managed, and gateway deployment and management are simple.
2. In Huawei ' s CloudFabric Network Virtualization Solution, which of the following software connects to the server virtualization platform?
A) iMaster NCE-Fabric
B) iMaster NCE-FabricInsight
3. (Which of the following statements is false about the underlay and overlay networks?)
A) The devices (such as servers, VAS devices, and external routers) connected to NVEs are unaware of the underlay network.
B) Generally, the overlay network is implemented through VXLAN.
C) The overlay and underlay networks must use the same routing protocol.
D) An overlay network is a logical network defined on a physical bearer network (underlay network).
4. 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
5. Multichassis Link Aggregation Group (M-LAG) bundles multiple physical links connecting ServerA (a device or host) to DeviceA and DeviceB into a logical link, and allows DeviceA and DeviceB to appear to ServerA as a single device, improving link reliability from card-level to device-level.
A) TRUE
B) FALSE
