true or false
1. The measurable service feature of cloud computing refers to charging based on time and
usage.
-False
2. When the VM is accessed using VNC, the network is no longer required.
-False
3. The virtualization technology can be used to virtualize a physical server into multiple VMs,
improving the hardware performance of the physical server.
-False
4. Virtualization consists of computing virtualization, storage virtualization, and network
virtualization, corresponding to cloud hosts, cloud hard disks, and cloud networks in cloud
computing
-False
5. Virtualization features include partitioning, isolation, encapsulation, and independence.
-True
6. The Libvirt can connect to various Hypervisors to provide APIs in various languages. It is
completely transparent to upper-layer users.
-True
7. After the disks in an array form a RAID group, the server connected to the disk array
cannot directly access the RAID group. Therefore, you need to divide the disk array into
logical LUNs before allocating them to the server
-True
8. On Huawei FusionCompute, a management IP address must be configured for each DVS
to facilitate unified management.
-False
9. Hybrid cloud is a deployment mode that integrates features of the public cloud and
private cloud. The industry cloud is a form of hybrid cloud.
-False
10. After the memory overcommitment technology is used, the physical memory of the 128G
can provide 150G virtual memory.
-True
11. In the KVM, the I/O virtualization performance is poor by using the QEMU. If the Virtio is
introduced, the NIC rate can be improved.
-True
12. In OpenStack, Ceilometer provides charging capabilities.
-False
13. In Huawei FusionSphere, the memory and CPU resources used by a VM can only be
provided by the same cluster. Therefore, a maximum of computing resources that can be
used by a virtual machine cannot exceed a sum of resources available to all hosts in the
cluster.
