QUESTION 46
Regarding storage pools, the following statements are incorrect:

A shared file system can be mounted by multiple servers

ISCSI network storage can be assigned to virtual machines after being mounted on the host

NFS network file system can be accessed by multiple servers

There is no limit on the number of hosts that can mount the same shared file system

QUESTION 47
Which of the following statements about virtual machine online migration is correct?

When migrating hosts and storage online, the virtual machine’s memory data and image files are transmitted through the management network.

When migrating hosts and storage online, the virtual machine’s memory data is transmitted through the management network, while the image file is transmitted through the storage network.

When migrating a host online, the destination host’s virtual machine will be suspended first, then the memory data of the original virtual machine will be copied, and finally the original virtual machine will be shut down, and the destination host’s virtual machine will change from the suspended state to the running state.

If the migration is not completed within the migration timeout period, the system will suspend the original virtual machine so that it can quickly complete the migration. After the migration is completed, the virtual machine will be restored to the running state.

QUESTION 48
When the virtual machine is started, it prompts that the disk does not exist, but it exists in the CAS front-end interface and the disk capacity is also displayed. What may be the reason?

The backing-file of the virtual machine disk has been deleted

The virtual machine disk’s backing-file has been moved to another directory

There is a problem with the front-end interface display

Disk capacity is too small

QUESTION 49
Which of the following descriptions about virtual machines is correct?

A virtual machine is a complete system running on a physical server. It contains its own virtual CPU, memory, disk, network card and other virtual hard disk resources.

The virtual machine configuration file defines the virtual hardware information of the virtual machine

The virtual machine mainly includes configuration files and image files

The system time of the CVK host where the virtual machine is located will not be synchronized during the virtual startup process

QUESTION 50
Which of the following statements about the functions and effects of the CVM module is correct?

Each server needs to install CVM as the hypervisor layer of server virtualization

CVM is responsible for server hardware resource management and virtual machine creation management

If the server is only used for CVM management and not as a CVK computing resource, the server does not need to support hardware-assisted virtualization.

CVM supports high availability (HA), dynamic resource scheduling (DRS), virtual machine backup, network policy templates and other functions

QUESTION 51
The following are the advantages of SSD hard drives over SATA hard drives:

Good random read and write performance

Large hard disk capacity

Low noise during operation

No mechanical moving parts inside, no fear of vibration

QUESTION 52
Which statement about CAS log is correct?

/var/log/message log records the error log of CVK host system operation

/var/log/operation log records the command information executed in the cvk background

/var/log/ocfs_fence_restart.log records the information of the CVK host restart triggered by ocfs2 ? Fence

/var/log/libvirt/qemu stores the log files of the virtual machines running on this CVK host

QUESTION 53
Regarding server RAID cards, the correct statement is:

Server disks do not require array cards to be used for RAID0

write back mode, data will be written directly to the disk, high security

The array card cache must be used with a cache battery, otherwise there is a risk of data loss after a power outage

When using FBWC, data retention time does not exceed 72 hours. If the phone is disconnected, the server recovery data must be flashed to the hard disk as soon as possible.

QUESTION 54
Which of the following virtualization forms are used by CAS?

Hyper-V

Paravirtualization

Hardware-assisted virtualization

Simulation

QUESTION 55
Which of the following belongs to 1 virtualization technology?

UIS R150 installs CAS to create multiple Redhat virtual machines

P5000 storage uses 3 hard disks to create a RAID5 array

UIS P8000 creates a Virtual Domain

S12500 Create MDC

QUESTION 56
Which of the following errors regarding virtual machine migration is

Virtual machine migration refers to manually migrating a virtual machine to a different host and data storage, supporting offline migration and online migration

Virtual machine migration includes changing the host, changing the storage, changing the host and storage

When the virtual machine only changes the host, the destination host must be able to access the image file of the virtual machine

Changing the host and storage means migrating the virtual machine to another host and migrating the virtual machine image file to other storage on the host. Only offline migration is supported.

QUESTION 57
Which of the following statements about alarm management is correct?

When a host goes down, the CVM console will record relevant information and generate an alarm

When the virtual machine cannot connect, an alarm can be generated

The alarm information records the alarm source, abnormality occurrence time, possible abnormality causes, recovery suggestions, etc.

Administrators can manually record maintenance experience

QUESTION 58
Which of the following statements about CAS logs is incorrect?

The operation log records the information of user operations and system background automatic operations, and can be downloaded to the local for analysis

The log file collection page does not support collecting log files for a single CVK host under cloud resources

When the CVM host is abnormal, you can execute the “cas_collect_log_sh” command in the CVK host background to collect the log files of the CVK host.

When cleaning up operation logs, only operation logs older than three months are allowed to be deleted

QUESTION 59
CAS virtualization software includes the following components:

CVM

CVK

KVM

K8S

QUESTION 60
The following modification of virtual switch port information is incorrect.

To modify the host management vswitch address, you need to delete the host from the CVM page.

Modify the host service vswitch binding physical port can be modified directly on the CVM page

Changing the host storage vswitch address requires suspending the shared storage pool

To modify the host management vswitch name, you can directly modify it on the CVM page.

QUESTION 61
HA high reliability technology can achieve the following functions:

Automatically detect physical server failures

Automatically detect virtual machine crashes

Intelligently select idle physical servers

The virtual machine automatically restarts

QUESTION 62
The following description of virtual machine startup is incorrect

If the CVK host does not have hardware-assisted virtualization enabled, the virtual machine will not be able to start normally.

When the CPU of the CVK host reaches 87%, the virtual machine can still be started with less virtual CPU allocated

After a virtual machine fails to start, the startup failure information will be recorded in the “/var/log/libvirtd.log” log

When a suspended virtual machine is restarted after hibernation, the virtual machine remains in the suspended state.

QUESTION 63
The following three major IETF standards related to Overlay technology are:
