Question #21
Which of the following statements about storage resources is correct? (Multiple choice)
- A . Virtual machines can use storage resources in the form of block devices or files
- B . Two storage systems: defaultpool and ispool, of the local file directory type by default.
- C . Storage pool types include local file directories, LVM logical storage, iSCSI network storage, FC network storage, NFS network file storage, shared file storage and windows shared directories
- D . The identifier of the iSCSI storage adapter of the CVK host needs to be unique
- E . A block device is only allowed to be used by one virtual machine
Question #22
Which of the following statements about shared files is correct? (Multiple choice)
- A . Shared file system types include iSCSI shared file system and FC shared file system
- B . A shared file system is not allowed to be mounted by hosts under different host pools at the same time.
- C . FC shared file system does not support FC multipath
- D . Multiple clusters under a host pool are not allowed to use the same shared file system
Question #23
Which of the following descriptions about virtual machines is correct? (Multiple choice)
- A . A virtual machine is a complete system running on a physical server. It contains its own virtual CPU, memory, disk box, network card and other virtual hard disk resources.
- B . The configuration file of the virtual machine defines the virtual hardware information of the virtual machine
- C . The virtual machine mainly includes configuration files and image files
- D . During the virtual startup process, the system time of the CVK host where the virtual machine is located will not be synchronized.
Question #24
Which of the following statements about virtual devices of virtual machines is correct? (Multiple choice)
- A . The "custom" working mode of virtual CPU can provide optimal migration compatibility and optimal performance for virtual machines.
- B . When the virtual machine uses " virtio hard disk" or " virtio " network card, there is no need to install the virtio device driver.
- C . " virtio network card" has better performance than "ordinary network card". It is recommended to use " virtio network card"
- D . The virtual CPU of the virtual machine uses physical CPU resources through time slice polling.
Question #25
Which of the following descriptions of the virtual machine life cycle is correct? (Multiple choice)
- A . CAS Tools is not installed on the virtual machine, and there may be a problem that the virtual machine cannot be shut down when performing the shutdown operation.
- B . When the virtual machine is working normally, performing a power-off operation may cause the virtual machine operating system and application data to be lost, so it needs to be used with caution.
- C . During normal operation of the virtual machine, if the storage pool where the image file is located is full , the virtual machine will become suspended.
- D . After the virtual machine is moved to the recycle bin, it can be manually restored within the storage period. If the storage period expires, it will be automatically deleted.
Question #26
Which of the following statements about virtual machine templates is correct? (Multiple choice)
- A . A virtual machine template is a copy of a virtual machine and is used to easily create and configure multiple new virtual machines.
- B . The number of CPUs, memory size and storage capacity in the virtual machine template cannot be modified.
- C . Making a virtual machine template includes two methods: converting to a template and cloning to a template. Cloning to a template must be performed when the virtual machine is shut down.
- D . The virtual machine template is saved in the local directory "/ vms /templet" of the CVM host by default.
Question #27
Which of the following statements about virtual machine cloning is incorrect? (Multiple choice)
- A . Virtual machine cloning methods include normal cloning, fast cloning and full cloning.
- B . Cloning is only allowed within the same CVK host
- C . The cloned virtual machine has the same operating system, application system and data as the original virtual machine, and the MAC of the virtual network card is also the same.
- D . The IP address acquisition method of the cloned virtual machine defaults to DHCP, so there will be no address conflicts.
Question #28
Which of the following about virtual machine migration is wrong?
- A . Virtual machine migration refers to manually migrating virtual machines to different hosts. Under data storage, offline migration and online migration are supported.
- B . Virtual machine migration includes changing the host, changing the storage, changing the host and storage
- C . When the virtual machine only changes the host, the destination host must be able to access the image file of the virtual machine.
- D . Changing the host and storage means migrating the virtual machine to another host and migrating the virtual machine image file to other storage on the host. Only offline migration is supported.
Question #29
Which of the following statements about virtual machine online migration is correct? (Multiple choice)
- A . When migrating hosts and storage online, the memory data and image files of the virtual machine are transmitted through the management network.
- B . When migrating hosts and storage online, the memory data of the virtual machine is transmitted through the management network, and the image file is transmitted through the storage network.
- C . When migrating a host online, the virtual machine of the destination host is first sent off in a paused manner, and then the memory data of the original virtual machine is copied. Finally, the original virtual machine is shut down, and the virtual machine of the destination host changes from the paused state to the running state.
- D . When the migration is not completed within the migration timeout, the system will pause the original virtual machine so that it can quickly complete the migration. After the migration is completed, the virtual machine will be restored to the running state.
Question #30
Which of the following descriptions of virtual machine high availability (HA) is correct? (Multiple choice)
- A . HA functionality provides easy-to-use, cost-effective high availability for applications running on all virtual machines in the cluster
- B . After turning on the HA function, CVM will continue to monitor the running status of all server hosts and virtual machines in the cluster. When a host or virtual machine fails, CVM will respond immediately and start all affected hosts on other available hosts in the cluster. virtual machine
- C . After the HA function is enabled in the cluster, all hosts in the cluster are required to mount the system shared storage.
- D . After the cluster enables the HA function, all virtual machines under the cluster have HA enabled, and the HA function of a single virtual machine cannot be turned off.
