A. Hosts of the same virtual resource can be added to the same host group B. Virtual resources KVM and XEN hosts can be added to the same host group C. The same FusionCompute cluster cannot be added to different host groups. D. The same KVM host cannot be added to different host groups.

Correct Answer: A,D

Question 2

When the FusionSphere OpenStack being docking to KVM virtualized environment FusionStorage storage resource, it must perform control transfer through the FusionStorage Manager.

A. True B. False

Correct Answer: A

Question 3

When planning and designing a data center, A company conducts network design based on different business scenarios. The following are some solutions when planning and designing. Which description is wrong?

A. For the DMZ zone, the firewall is connected in series with the gateway. The traffic between the POD and the internal and external access must pass through the firewall. B. Multi-service hybrid deployment, requiring security isolation between services. The gateway can deliver multiple VRFs as needed, and the VPCs and the PODs must communicate with each other inside and outside the POD. C. For the service front-end area, the firewall is deployed next to the firewall, and the virtualization is enabled. The AC delivers the policy route according to the access policy defined by the cloud platform. D. Deploying a single service or deploying multiple services but on-demand isolation between services requires open east-west access and controlled north-south access. You can choose a security policy that does not pass the firewall by default.

Correct Answer: C

Question 4

Which of the following descriptions are correct about the FusionStorage main module MVC? (Multiple Choice)

A. Realize reliable storage of metadata (such as Topology, OSD View, Partition View, VBS View, etc.) through the ZooKeeper cluster. B. Obtaining and notifying the state change of the OSD and the VBS node by interacting with the message between the OSD and the VBS. C. Through the heartbeat detection mechanism, the status monitoring of the OSD and VBS is realized. D. Through the interaction with the agent, the system can be expanded and reduced, status query, and maintenance.

Correct Answer: A,B,C,D

Question 5

Which of the following description of the challenges for the cloud data center network is wrong?

A. Diversification requires an open network B. Cloud data center requires the device to fully support forwarding control separation C. Big data requires big pipes D. Business innovation requires network agility

Correct Answer: B

Question 6

In the operation process of B company, based on cost considerations, it is planned to put some of the business on the public cloud, and some of the business is placed on the private cloud. The following description of the private cloud and the public cloud, which is correct? (Multiple choice)

A. In the private cloud, when the business east-west traffic is large, the security group can be configured to be isolated as needed. B. Public cloud generally divides a VDC into one tenant C. The general north-south traffic in the private cloud must be controlled by firewall. D. POD is divided in the private cloud based on security level or performance level.

Correct Answer: A,B,C

Question 7

In the Huawei SDN solution, which of the following description of the deployment architecture of the vDC active/standby disaster recovery scenario is wrong?

A. Multiple DC calculations and networks are unified resource pools B. Support both network virtualization and cloud network integration scenarios C. The networking architecture of multiple DCs can be different. D. Multiple DCs are end-to-end VXLAN domains

Correct Answer: C

Question 8

An abnormal alarm about the available partition data status is found in the daily monitoring of ServiceCenter. Which of the following is the possible causes?

A. Access component management process service terminated or database inaccessible B. ServiceCenter cloud resource pool connection status is abnormal. C. The user has deleted the corresponding available partition under FusionSphere OpenStack connected to the ServiceCenter. D. Modified the domain name of FusionSphere OpenStack and synchronized the domain name of ServiceCenter

Correct Answer: A

Question 9

About the basic concept of data center resources, which of the following is incorrect?

A. AZ is an independent fault domain within the data center. B. Cluster is the data center virtualization network isolation boundary. C. Region is a region, such as the Asia Pacific region. D. DC is a data center concept, such as Beijing, Hong Kong, and Tokyo data centers.

Correct Answer: B

Question 10

About the description of deployment of Huawei dual active data center network layer, which is correct? (Multiple Choice)

A. Each site deploys a separate GSLB to achieve load balancing between sites. B. Two SLBs are deployed at each site to form an HA cluster to implement load balancing of application layer servers. C. Huawei CloudEngine series data center switches are used as core switches. D. The data center uses a typical Layer 2 or Layer 3 physical architecture network. The core switch is aggregated to access the WDM device through the CSS+ link.

Correct Answer: A,B,C,D

Question 11

In a cloud data center scenario, network isolation between tenants is required to ensure security and avoid attacks. Which of the following description about network isolation measures is wrong?

A. When multi-tenant shares cluster resources, for management reasons, port isolation and Layer 3 isolation do not need to be deployed at the same time. B. Each tenant enjoys exclusive cluster resources for physical network isolation. C. When multi-tenant shares cluster resources, VPN isolation can be used as needed in the data center Layer 3 network. D. When a multi-tenant shares cluster resources, the virtualized network uses VLANs for Layer 2 isolation.

Correct Answer: B

Question 12

The following is about the description of VAS device deployment in Huawei Cloud Data Center, which is correct? (Multiple choice)

A. When the hardware FW is connected to the centralized gateway, the gateway traffic can be selectively directed to the firewall, that is, the traffic that needs to be detected by security is directed to the firewall for processing. B. When the hardware FW/LB is connected to the centralized gateway, all north-south traffic will pass through the firewall, which wastes the interface bandwidth and increases the network fault point. It is more troublesome to expand or rebuild later. C. When the centralized hardware gateway is connected to the VAS device, you need to manually configure the traffic diversion mode on CE. D. When the service leaf is attached to the hardware or software FW/hardware LB, the FW and LB are easy to expand, but the north-south traffic will bypass.

Correct Answer: C,D
