Hybrid cloud is a cloud computing model that integrates one or more public or private cloud environments through network connections, allowing data and applications to be shared between these cloud environments.

Core plug-ins of open source OpenStack Neutron integrate Layer 2 network services supported by various vendors and backend technologies and provide basic network services including networks, subnets, and ports.

The CloudFabric intelligent O&M solution can aggregate faults, trace their sources, and automatically locate their root causes.

Which of the following statements is false about the container and VM technologies?

You can use Ethernet switches with all or part of optical ports to build a Fibre Channel storage network.

In the CloudFabric solution for the hybrid cloud scenario, which of the following interconnection modes are supported between the public cloud and private cloud? (Choose all that apply.)

The Linux namespace mainly solves the environment isolation problem. We also need to isolate the usage of computer resources. Which of the following technologies is used to meet this requirement?

Which of the following statements is false about RDMA?

When a server uses local storage devices, which of the following file systems may be used? (Choose all that apply.)

When a centralized storage application writes the original and backup data to multiple servers, 1:N incast traffic is generated.

Based on the change management functions of the CloudFabric solution, which of the following change functions are provided by iMaster NCE-FabricInsight? (Choose all that apply.)

In the Huawei CloudFabric solution, when a tenant orchestrates the VPC communication service, interconnection VRFs may be required. Which of the following statements is true about interconnection VRFs?

In the CloudFabric solution for the Multi-Site scenario, which of the following statements are true when segment VXLAN is used to implement communication? (Choose all that apply.)

Microsegmentation has a finer segmentation granularity than traditional ACLs. Which of the following granularities does microsegmentation support? (Choose all that apply.)

On a DCN, which of the following protocols can be used to dynamically establish VXLAN tunnels?

An OVS is a distributed virtual switch and can help VMs maintain consistent network configurations and policies before and after migration between hosts.

Which of the following statements are true about the consistency check function of iMaster NCE-Fabric? (Choose all that apply.)

In the Huawei CloudFabric solution, distributed VAS resource pools have higher resource utilization than centralized VAS resource pools and are therefore recommended in all scenarios.

Which of the following layers are included in the architecture of the CloudFabric solution for the container network scenario? (Choose all that apply.)

Which of the following is not included in the protocol health evaluation scope of iMaster NCE-FabricInsight?

On a VXLAN network, after the distributed gateway function is enabled on a VBDIF interface, the device where the VBDIF interface resides deletes ARP entries learned from the network side.
