A. Each organization can be allocated multiple cluster computing resources

B. Organization administrators can only approve virtual machine electronic flows within one organization.

C. A cluster can only be assigned to a certain organization.

D. Virtual machines requested by users in the R&D organization only occupy the computing and storage resources of the R&D organization.

A. Services are quantifiable

B. Network distribution

C. Self-service

D. Resource pooling

E. Flexible Scheduling

A. The virtual machine can mount the storage volume on the CVK as a block device

B. Multiple virtual machines can mount the same disk file

C. The virtual machine can directly access physical storage mounts through the network

D. You can create a new file in the CVK mounted storage pool and mount it to the virtual machine for use

A. If both the virtual machine and the cluster set the startup priority (the virtual machine is set to non-default), the startup priority set in the cluster will take precedence.

B. The virtual machine startup priority can be set to: default, low, medium, high

C. If the virtual machine startup priority is set to default, the startup priority set in the cluster will be used.

D. The virtual machine startup priority can be configured on the virtual machine or on the cluster

A. Multipathing can be implemented in two modes: Active-Active mode and Active-Passive mode.

B. The main function of multipath is to improve reliability and achieve load balancing, but it cannot increase link bandwidth.

C. If there is no multipath software, one LUN will be recognized as multiple LUNs on the host side.

D. If the host has two HBA ports, the storage side has two controllers, and each controller has two HBA ports, then the host side can discover a total of 4 storage paths

A. Full backup backs up the most data

B. Differential backup does not support CBT

C. Differential backup The first backup is a full backup

D. Incremental backup is the fastest

A. /var/log/libvirt/qemu stores the log files of the virtual machines running on this CVK host

B. /var/log/ocfs_fence_restart.log records the information of the CVK host restart triggered by ocfs2 ? Fence

C. /var/log/message log records the error log of CVK host system operation

D. /var/log/operation log records the command information executed in the cvk background

A. The virtual machine template is saved in the "/vms/templet" local directory of the CVM host by default

B. There are two ways to create a virtual machine template: convert to a template and clone to a template. The clone to template must be executed when the virtual machine is shut down.

C. The number of CPUs, memory size, and storage capacity in the virtual machine template cannot be modified

D. A virtual machine template is a copy of a virtual machine that is used to easily create and configure multiple new virtual machines.
