To configure memory for a virtual machine, the following statement is correct

• A.The virtual machine memory is modified online, and a cold restart of the virtual machine is required to take effect
• B.The memory allocated to a virtual machine can be greater than the physical memory
• C.The memory configuration of all virtual machines on a host may be greater than the total memory of the host.
• D.The virtual machine does not occupy memory when it is turned off

Which of the following descriptions about virtual machine high availability HA is correct?

• A.HA functionality provides easy-to-use, cost-effective availability for applications running on all virtual machines in a cluster.
• B.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.
• C.After the cluster enables the HA function, all hosts in the cluster are required to mount the system shared storage
• 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.

Which of the following statements about CAS characteristics is correct:

• A.HA takes into account the virtual machine CPU, memory, I/O throughput load factors and the virtual machine's affinity to the physical host to dynamically adjust the distribution of business loads and improve system availability.
• B.V2V supports converting virtual machines in various formats such as VMware, Citrix, KVM, etc. into H3CCAS virtual machines
• C.DRX takes into account the virtual machine CPU, memory, I/O throughput load factors and the virtual machine's affinity to the physical host to dynamically adjust the distribution of business loads and improve system availability.
• D.When a server fails, DRS can automatically select a space server and restart the VM on an idle server.

The following statement about modifying a virtual machine is correct:

• A.You can set the virtual machine to start with the host, but this function becomes invalid after HA is enabled.
• B.After the virtual machine is created, you can add hard disks, network cards and other devices to the virtual machine
• C.After the virtual machine is created, the display name cannot be modified.
• D.All types of virtual hard disks support online addition and expansion.

The following are the advantages of SSD hard drives over SATA hard drives:

• A.Large hard disk capacity
• B.Low noise during operation
• C.Good random read and write performance
• D.No mechanical moving parts inside, no fear of vibration
