H3C Deploy and Manage the H3C CAS virtualization platform V3.0 - GB0-713 模擬練習

A. After the cluster enables the HA function, all hosts in the cluster are required to mount the system shared storage

B. HA functionality provides easy-to-use, cost-effective availability for applications running on all virtual machines in a cluster.

C. After the cluster enables HA, all virtual machines in the cluster have HA enabled, and the HA function of a single virtual machine cannot be disabled.

D. After enabling the HA function, CVM will continuously monitor the operation of all server hosts and virtual machines in the cluster. When a host or virtual machine fails, CVM will immediately respond and restart all affected virtual machines on other available hosts in the cluster.

A. Intelligently select idle physical servers

B. The virtual machine automatically restarts

C. Automatically detect physical server failures

D. Automatically detect virtual machine crashes

A. The alarm information records the alarm source, abnormality occurrence time, possible abnormality causes, recovery suggestions, etc.

B. Administrators can manually record maintenance experience

C. When the virtual machine cannot connect, an alarm can be generated

D. When a host goes down, the CVM console will record relevant information and generate an alarm

A. This operation has no impact on the original virtual machine architecture

B. The cloned virtual machine disk is a three-level architecture

C. The Base0 file of the cloned virtual machine disk is not the same as the Base0 file of the original virtual machine disk.

D. The cloned virtual machine disk data may be different from the original virtual machine data

A. Hardware-assisted virtualization

B. Simulation

C. Hyper-V

D. Paravirtualization

A. CVK supports ISCI, FC, and NAS to prevent mounting storage resources

B. CVK host must support hardware-assisted virtualization

C. CVK host does not support USB installation

D. Each server needs to install CVK components

A. Each server needs to install the CVK component

B. When a CVK and the cluster shared file system both fail, cluster HA can still migrate the virtual machines on the failed CVK to other CVKs

C. CVK host must support hardware-assisted virtualization

D. CVK supports ISCSI, FC, and NAS methods to mount storage resources

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

B. 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

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

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

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

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

C. Shared storage is required to implement HA

D. 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
