1. Which of the following is the encapsulation order of the iSCSI protocol packets?

A. iSCSI->SCSI->TCP->IP->Link

B. Link->SCSI->iSCSI->TCP->IP

C. SCSI->iSCSI->TCP->IP->Link

D. iSCSI->SCSI->IP->TCP->Link

2. Among the following descriptions of the server RAID cards, which is correct:

A. No RAID card is required for establishing RAID0 for server disks.

B. In write back mode, data will be written into the disks directly, featuring high security.

C. RAID card cache needs to be used with cache batteries; otherwise, data may get lost in case of power-down.

D. If FBWC is used, the data retention time will not exceed 72 hours. After power-down, the server shall be recovered and data shall be written into hard disks as soon as possible.

3. Which of the following are features of cloud computing?

A. Self service

B. Resource pooling

C. Flexible dispatching

D. Services quantizable

E. Network distribution

4. What are the values of the virtualization technology?

A. Saves hardware cost and electric power cost

B. High Availability (HA) guarantees continuous operation of services

C. Reduces the planned downtime

D. Breaks through the traditional shaft structure to facilitate horizontal and vertical expansion of resources

5. Which of the following virtualization mode is used by CAS?

A. Hyper-V

B. Para-virtualization

C. Hardware-assisted virtualization

D. Emulation

6. Among the following descriptions of HA of a cluster, which is incorrect？

A. To realize HA, shared storage needs to be used.

B. On the hosts where HA of a cluster is realized, the same shared storage shall be mounted.

C. After HA is enabled, if one host in the cluster is faulty, the system can select another idle server and restart the VMs of the faulty host on the idle server.

D. After HA is enabled in a cluster, if the server and shared file system are both faulty, the service continuity can still be guaranteed.

7. Among the following descriptions of CAS cloud resources, which is wrong?

A. The HA function is realized with cluster as the unit.

B. A physical server is a host on the CAS platform.

C. Shared file system is realized with cluster as the unit.

D. On one host, multiple shared file system storage pools can be added.

8. Among the following descriptions of CVM management functions, which are correct?

A. The VM view management function enables the maintenance personnel to customize VM directories based on actual business scenarios.

B. Cloud services are based on the virtualization capability provided by the CVM component, abstracting physical resources such as computing, storage, and network resources as flexible virtual resource pools which can be provided according to requirements.

C. Host auto discovery task management can automatically search for addable hosts and add them to the cluster of the task.

D. Operation logs can record in details operations performed by all operators on CVM, and provide the download function.

9. Among the following descriptions of VM startup, which is incorrect?

A. If the CVK host does not enable the hardware-assisted virtualization function, VMs cannot be normally started.

B. If the CPU load of a CVK host reaches 87%, the VMs which have been assigned with small virtual CPU can be started.

C. After a VM fails to be started, the startup failure information will be recorded in the “/var/log/libvirt/libvirtd.log” log.

D. After a VM that is in the suspended status is restarted from the dormant status, the VM is still in the suspended status.

10. In the case of VM backup error, which of the following cause is impossible:

A. Insufficient storage resources in the destination path of VM backup

B. Exceeded time specified in backup policy

C. Insufficient storage resources in the temporary path of VM backup

D. Too low priority set for VM backup
