1. In the FusionSphere OpenStack scenario, “physical network” defines mappings between virtual networks and host physical network ports and the applied networks planes, and a VM can derectly use the physical network.

2. In Huawei cloud computing solution, the “raw devices + logical volumes” mode is the most direct storage virtualization that supports advanced storage function and is wasy to manage.

3. In a large-scale IDC, the DHCP service is deployed to allocate IP addresses to a large number of servers, enabling the servers to go online quickly and simplifying server configuration, IP addresses can be allocated to servers across network segments.

4. FusionCloud UltraVR can be installed on a VM or physical server and it exclusively occupies resources of the VM or physical server.

5. In Huawei SD-DC2 solution, physical data centers are deployed in a distributed manner and there is a federation relationship between data centers. Therefore, the domain concept is introduced. One domain can contain one or multiple VDCs that belong to one or more enterprises.

6. In Huawei UltraVR disaster recovery solution, the following is recommended: At the production and disaster recovery sites, use LUNs that are not configured with remote replication to store VMs that do not need disaster recovery, and use LUNs configured with remote replication to store VMs that needs disaster recovery.

7. OS virtualization architecture, which operates on physical hardware with low loss and high efficiency, will become the mainstream development trend in the future.

8. Huawei SD-DC2 employs the eBackup virtualization backup solution. When a backup agent fails, services are switched to other backup agents.

9. The traffic diversion function is required only when an AntiDDoS device is deployed on out-of-path mode.

10. in a HyperMetro active-active data center solution, which statement is true about the active-active deployment of the B/S application?
