A. Access the CAS management platform through a virtual IP

B. The primary CVM only synchronizes the data under the /vms path to the backup CVM in real time

C. CVM hot standby arbitration only supports the simple Ping method, not the advanced arbitration method

D. The CAS versions of the active and standby CVMs can be inconsistent

A. S12500 Create MDC

B. P5000 storage uses 3 hard disks to create a RAID5 array

C. UIS R150 installs CAS to create multiple Redhat virtual machines

D. UIS P8000 creates a Virtual Domain

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

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

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

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

A. ONEstor distributed storage

B. UIS Hyperconvergence

C. CAS Virtualization Platform

D. ClouDOS cloud operating system

A. After HA is enabled, when a host in the cluster fails, the system can select an idle server and restart the VM on the failed host on the idle server

B. Hosts that implement HA in the cluster need to mount the same shared storage

C. Shared storage is required to implement HA

D. The cluster enables HA, which can ensure business continuity even when both the server and the shared file system fail.

A. IOPS

B. Bandwidth

C. Maximum number of luns supported

D. Maximum number of supported servers

A. Cloud resources mainly include computing resources, storage resources and network resources

B. Cloud resource management mainly includes host pool management, cluster management, host management, virtual machine management, virtual machine template management, policy management, storage management and network management

C. You can directly create a cluster under cloud resources and add hosts to the cluster

D. Hosts can be added directly to a host pool or to a cluster

A. HA high reliability ensures business continuity

B. Break the traditional silo architecture and facilitate horizontal and vertical expansion of resources

C. Reduced planned downtime

D. Hardware cost and electricity cost savings

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

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

C. Make sure the CD-ROM drive is disconnected before creating the template

D. There are two ways to create a virtual machine template: converting to a template and cloning. Cloning to a template must be done when the virtual machine is shut down.
