3. The virtual machine network QoS policy provides bandwidth configuration control capabilities, and the QoS function supports traffic restrictions between virtual machines on the same host.

4. Load balancing can share specific services to multiple network devices or multiple links, thereby improving service processing capabilities and ensuring high service reliability.

5. Which of the following can achieve load balancing between different hosts in a FusionCompute cluster?

6. In the early stage of an enterprise's operation, two physical hosts are used to deploy the FusionCompute platform to carry services. The two hosts are in the same cluster. VM 1 runs on host A and VM 2 runs on host B. The service needs to reduce the load on host A, the technician is now migrating VM1 on host A to host B and finds that the migration cannot be completed. Which of the following is the possible reason?

7. Which of the following is not a feature of 5G?

8. A company is migrating its service system to the FusionComute virtualization platform, and the management plane and service plane are on different network segments. However, due to incorrect configuration, services of a Linux virtual machine cannot run normally after the migration. Which of the following methods cannot be used by engineers to log in to the faulty virtual machine for troubleshooting?

9. In the FusionCompute virtualization platform, Tools are installed in the same way on all operating systems.

10. As a rapidly developing technology in recent years, cloud computing has its own unique advantages. The advantages of cloud computing include: on-demand self-service, extensive network access, higher performance, and measurable services.

21. Which of the following descriptions about KVM is correct?

22. Which of the following descriptions about the development of cloud computing architecture is wrong?

23. Which of the following descriptions about cloud computing is wrong?

24. In virtualization, the disk files of the virtual machine will be stored in the file system in the form of files, but from the perspective of the virtual machine operating system, the virtual machine disks, like ordinary disks, can be seen in the "hardware resources" of the system.

25. Compared with mechanical hard disks, solid hard disks have the advantages of good shock resistance, small size, no sound insulation, small heat dissipation and low price.

26. Solid-state drives are suitable for scenarios where data access is very frequent.

27. Under thin provisioning, only the virtual storage space of written data will actually allocate physical storage and virtual storage space of unwritten data does not occupy physical storage resources.

28. A company intends to purchase a batch of hard disk devices, which are mainly used to store archived data. Considering the large amount of data, it is recommended that the company purchase solid-state hard disks.

29. When a user uses a virtual machine, the disk of the virtual machine is the same as a common hard disk on the operating system, and is a hard disk from the user's perspective.

30. In the NAT technology, through the server mapping function, it is possible to realize the requirement that the virtual machine inside the virtualization platform can access the external network service through the public network address.

31. The large 2-layer network architecture can meet the large east-west traffic demand of the data center.

32. The existing two hosts A and B are interconnected through a layer switch, and A and B belong to different VLANs. When host A sends a broadcast message to the network, host B will receive a message whose destination MAC is all "F".

33. When enterprises use KVM virtualization, they can choose the method of device simulation for I/O virtualization, which has good compatibility, no hardware dependence, and the user's operating system does not need to be modified, but the I/O performance will be relatively poor.

34. The IP SAN network mainly builds a storage network with Ethernet as the bearer. And use the iSCSI protocol for transmission.

35. All RAID levels can enhance the fault tolerance of the system and improve the read and write performance of the storage system.

36. When a certain end on a secondary switch is only sending messages, it cannot receive messages from another device.

37. Using Virtio for device simulation can shorten the path of I/O requests and improve the performance of virtualization.

38. Which of the following is not a function of a virtual machine?

39. In FusionCompute, when virtual machines are live migrated across hosts (CPUs of different Intel models), which one of the following policies needs to be set for the cluster?

40. Which of the following descriptions about the expansion requirements of virtual machine disks in Fusion Compute is correct?
