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.
- A . True
- B . False
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.
- A . True
- B . False
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.

- B . False
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.
- A . True
- B . False
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.
- A . True
- B . False
FusionCloud UltraVR can be installed on a VM or physical server and it exclusively occupies resources of the VM or physical server.
- A . True
- B . False
As shown in the figure, the two core switches set up a VRRP group and run BFD for VRRP. The BFD feature can shorten the VRRP master/backup switchover time to 50 ms and monitor multiple VRRP group.
- A . True
- B . False
in a HyperMetro active-active data center solution, which statement is true about the active-active deployment of the B/S application?
- A . A unified SLB resource pool is established for the primary and secondary sites, and all web servers are added to this pool.
- B . Web servers at the primary and secondary sites compose a web cluster across sites.
- C . Application servers compose a cluster across sites.
- D . Databases do not need to compose a cluster across sites.
In a HyperMetro active-active data center solution, which statement is false about computing resource virtualization?
- A . Deploy a virtualization cluster in each of the two data centers. After virtualizing computing resources .deploy VMs.
- B . Configure the HA function to protect VMs and enable them to recover automatically upon faults.
- C . Configure dynamic resource schedulers (DRSs) to distribute VMs over multiple host machines based on service requirements
- D . Map the shared storage space provided by the active-active storage platform to all host machines in the virtualization cluster to enhance the flexibility of VMs
Which CPU virtualization will become the mainstream development trend in the future?
- A . Full-virtualization
- B . Para-virtualization
- C . Hosted virtualization
- D . Hardware-assisted virtualization
On the DC network shown in the following figure, a Huawei agile controller is used as the SDN controller to manage the VXLAN service between two CE12808 switches. Which of the following descriptions is incorrect?
- A . The agile controller users and SSL-encrypted channel to deliver commands to and receive information from
- B . The agile controller centralizes the computation on home computation-intensive protocols to the control plane.
- C . The agile controller can use group tables. (A type of openflow flow table) to support additional forwarding behavior (such as select)
- D . CE series switches. When serving as openflow agents. Must have the agile controller address configured locally and connect to multiple controllers to increase stability
In a C/S service model among a VM cluster spanning multiple data centers, which method can not support cross-DC traffic switching upon a VM migration when external users access a data center?
- A . Inject the host route of the VM using CE12800’s RHI feature (EVN all-active gateway features)
- B . Inject the host route of the VM using the SLB’s RHI feature.
- C . Use MPLS tunneling technology to ensure optimal access paths.
- D . Change the service model to B/S and use a GSLB to ensure optimal access paths
