If a virtual machine wants to communicate with other virtual machines, which of the following options is necessary?
In FusionCompute, the QoS parameters that can be set for the virtual machine do not include:
In Huawei Fusion Compute, the following incorrect description of memory reuse is
In Huawei FusionCompute, users log in to a virtual machine using VNC and find that they cannot operate normally and are stuck (such as being unable to open files). The most likely cause of this failure is.
The main purpose on open NUMA functions are correct is ()
A, optimize memory access performance of the virtual machine
Computing capacity B, to maximize the physical host CPU
C, to maximize the physical memory of the machine multiplexing rate
VCPU computing power of D, maximize virtual machine
In actual work, which function can VLAN implement
A The virtual machine IXUS belonging to the same VLAN uses the IP address of the same address segment, otherwise it cannot communicate normally
B The virtual machines of the two departments cannot communicate with each other after using different VLANs
C virtual machines belonging to the same VLAN can use IP addresses in different address segments and can use broadcasts to discover each other
D virtual machines belonging to different VLANs can use the same IP address without address conflicts
Which of the following requirements can be fulfilled by Huawei FusionCompute DRS rules C
In computing virtualization, the operating system running in the virtual machine is called the Host OS.
Common disk arrays include (multi-select)
A MAID (massive arrays of Idle disks)
B RAID
C JBOD (Just a bunch of Idle disks)
D SBOD (Switch of bunches Idle disks)
The method used by FusionCompute Installer to deploy VRM virtual machines is (). B
When a virtual machine on a physical host fails, it will not affect other virtual machines on the physical host. Which characteristic of virtualization technology is this?
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. B
A TRUE
B FALSE
RAID 6 enhances the fault tolerance of disks on the basis of RAID 5, allowing two disks to be exported
It is faulty, but the number of disks required must not be less than 4
In KVM, there are two ways for the virtual machine NIC to connect to the physical network: and ()

B address translation, pass-through
C bridge, pass-through
D pass-through, bridge
In Huawei FusionCompute, the tools installed for the virtual machine have nothing to do with the type and version of the operating system used by the virtual machine // System-dependent
Using virtualization technology can virtualize a physical server into multiple virtual machines, thereby improving the hardware performance of the physical server.
In KVM-type virtualization, the following description is correct (multi-select)
A, Guest OS can be Windows
B. Guest OS can be Linux
C, Host OS can be Windows
D, Host OS can be Linux
SSD disks are mechanical hard disks, which have the advantages of fast read and write speeds, low power consumption, and light weight, but they have a limited life span
A virtual machine can have multiple virtual NICs at the same time, corresponding to different virtual switches
NUMA is a memory architecture designed for multiprocessor computers. Memory access time depends on
Processor location, under NUMA, the processor accesses its own local memory faster than non-local memory (the memory is located in
Another processor, or shared memory between processors) is faster.

A The communication between the source host and the destination host is normal
B destination storage for different storage devices
C virtual machine status is "running"
D destination host must have sufficient resources
