11. When FuisionStorage hardware failure, the possible conditions are:

Single hard disk failure, data loss

Two hard disks on one server fail at the same time, data is lost

Single server failure, data loss

The hard disk on two different servers is faulty at the same time, data is lost.

12. The correct description of FusionServer using of iSCSI storage is: (Multiple Choice)

The storage device used by FusionComputer is a LU

If you are sensitive to performance requirements, you do not need to purchase additional switch and network card

Support storage and host multi-pair connection, and support load balancing

Storage interface uses active/standby mode port binding to increase storage bandwidth

13. A virtual machine has only one hard disk. Users have created 10 snapshots. Then, how many VHD files associated with this virtual machine are saved in the FusionCompute?

14. When backup software backup in the FusionSphere backup and recovery solution, each virtual machine need to install a backup agent and unable to restore the system volume.

TRUE

FALSE

15. Compared to traditional architecture SAN storage, the advantages of Server SAN are:

Non-dependent RAID, high available storage space utilization

Use a pair of servers as storage controller to support high performance CPU and memory

Using distributed Cache to overcome Cache bottlenecks

The hardware is not easily damaged, such as hard disks, power modules, etc.

16. Which three military regulations does Huawei cloud environment emergency treat? (Multiple choice)

the first time to resume operations

problem before positioning clear, without changing the existing network configuration

for critical operations to be careful, to inform customers, to avoid improper handling causing problems expansion

too urgent, and direct operations without obtaining customers permit

17. Which of the following statement about computing resources on-line adjustment in Huawei computing virtualization is wrong? (Multiple choice)

vCPU, vRAM online add function is not supported by all OS

for not support hot add OS, FusionCompute supporting restart of virtual machines take effect

FusionCompute provide CPU, memory heat delete function.

All OS support vCPU, vRAM online add function

18. Which mode of disaster recovery does Huawei cloud computing disaster recovery solution framework contain? (Multiple choice)

based on storage array replication disaster recovery

Virtual Machine Backup

host replication disaster recovery

VIS dual-active disaster recovery

19. Regarding the memory QoS of FuslonCompute, the incorrect statement is:

Through memory QoS, you can solve the problem of resource preemption during memory reuse.

Memory QoS technology is as effective as physical machines

Memory QoS technology is mainly achieved by setting memory reservation and memory share.

After the memory size is set, the memory that the virtual machine can use cannot exceed the size.
