Huawei HCSP-Presales-Data Center Network Planning and Design V1.0 Sample Questions:
1. Which of the following is not a characteristic of high-performance networks?
A) Zero packet loss
B) Low latency
C) Higher GPU computing power
D) High throughput
2. Which of the following network components in OpenStack interconnects with iMaster NCE-Fabric?
A) Neutron
B) Nova
C) Keystone
D) Cinder
3. Which of the following are characteristics of distributed VXLAN gateways?
A) The number of ARP entries supported is a bottleneck. A single Layer 3 gateway is used. For tenants whose traffic is forwarded by the Layer 3 gateway, ARP entries must be generated for the tenants on the Layer 3 gateway, but only a limited number of ARP entries are allowed by the Layer 3 gateway, which impedes data center network expansion.
B) Forwarding paths are not optimal. Inter-subnet Layer 3 traffic between devices connected to the same gateway in a data center must be transmitted to a unified Layer 3 gateway for forwarding.
C) A distributed VXLAN gateway (leaf node) only needs to learn the ARP entries of servers connected to it, whereas a centralized Layer 3 VXLAN gateway needs to learn the ARP entries of all servers on a network. Therefore, the number of ARP entries supported is no longer a bottleneck on distributed VXLAN gateways, and the network scalability is improved.
D) A leaf node can function as both a Layer 2 VXLAN gateway and a Layer 3 VXLAN gateway, supporting flexible deployment.
4. Which of the following statements is false about the overlay network or underlay network?
A) The underlay network is transparent to devices (such as servers, VAS devices, and external routers) that are connected to NVEs.
B) The overlay network has an independent forwarding plane and an independent control protocol, which are VXLAN and BGP EVPN, respectively.
C) The overlay network requires bare optical fibers for links.
D) The overlay network is a logical network that is established over the underlay network through VXLAN.
5. (In the CloudFabric Solution, a PoD or site is a network fault domain managed by the SDN controller. It contains one or more spine-leaf architectures.)
A) FALSE
B) TRUE
