The weakest data redundancy of the following RAID levels is ()
A. RAID 1
B. RAID 6
C. RAID 0
D. RAID 5
In Huawei FusionCompute, when a host in the cluster fails, the virtual machine on that host will automatically Automatic migration to other hosts in the cluster
A. TRUE
B. FALSE
The SAN provides the host with a "bare disk" without a file system. What file system is built on it depends entirely on the host's operating system.
A. TRUE
B. TRUE
The following incorrect description of memory reuse is
A. memory reuse technology can make the sum of virtual machine memory specifications larger than the sum of physical server specifications
B. memory reuse technology can make the total memory used by virtual machines larger than the total memory of physical server specifications
C. After the C memory reuse function is enabled, the memory reuse rate is inversely proportional to the actual memory usage of each virtual machine.
D. memory reuse single technology includes memory bubbles, memory swap and memory sharing
The following description about making templates in FusionCompute is incorrect .
A. "Virtual machine to template" is to directly convert a virtual machine into a template, all parameters use the current configuration of the virtual machine The virtual machine will no longer exist after conversion
B. When using a virtual machine to make a template, the status of the virtual machine can be "running"
C. "Clone a template as a template" is to copy the template as a new template and support adjustment of some parameter configurations, which can be slightly different from the original template The difference is that the template still exists after cloning is complete
D. "Clone a virtual machine as a template" is to copy the virtual machine as a template and support adjustment of some parameter configurations, which can be compared with the original virtual machine. The virtual machine is slightly different. The virtual machine still exists after cloning is complete.
The function of the Internet of Things is only to collect data generated by various things.
A. Yes
B. wrong
The necessary conditions for a virtual machine to communicate with other virtual machines are (multiple choice)
A. Configure a fixed IP address for the virtual machine
B. Configure the correct IP address for the virtual machine
C. Configure the correct MAC address for the virtual machine
D. Configure the gateway address for the virtual machine
Huawei FusionCompute can sense the use of global physical resources during the running of a virtual machine, and use an intelligent scheduling algorithm to calculate the best host suitable for the virtual machine to run, and run the virtual machine on the best host by means of hot migration, Thereby improving the global business experience
A. True
B. False
In the following description, in line with the characteristics of the virtual package (multiple) the
A. The configuration file of the virtual machine contains information such as CPU type and quantity.
B. Virtual machines can be migrated from one physical host to another
C. Multiple virtual machines can run on one physical host at the same time
D. If a virtual machine has multiple hard disks, each hard disk will generate a corresponding disk file
The storage resource types supported by Huawei FusionCompute are (multi-select)
A. FusionStorage
B. Advanced SAN
C. NAS
D. IP SAN
E. FC SAN
