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

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

NO.53 Three ways to backup a virtual machine. After multiple backups, which of the following statements is correct?

Full backup backs up the most data

Incremental backup is the fastest

Differential backup does not support CBT

Differential backup The first backup is a full backup

NO.54 Which of the following statements about CVM management functions is correct?

The virtual machine view management function allows maintenance personnel to customize the virtual machine directory based on actual business scenarios

Cloud services are based on the virtualization function provided by CVM components, abstracting physical resources such as computing, storage, and network into elastic virtual resource pools that are provided on demand.

Host auto-discovery task management automatically searches for hosts that can be added and adds them to the cluster to which the task belongs.

The operation log records in detail all operations performed by operators on the CVM and provides a download function

NO.55 Which of the following components does CAS virtualization software include?

CVM

CVK

KVM

CIC

NO.56 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

NO.57 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.

NO.58 Regarding Intel E5-2600v3 CPU, which of the following statements is correct?

belongs to Intel Xeon E series processor

The processor supports up to 2 CPUs

Based on Ivy bridge technology

Each CPU supports 4 memory channels

NO.59 Which of the following statements about CAS characteristics is correct:

When a server fails, DRS can automatically select a space server and restart the VM on an idle server.

V2V supports converting virtual machines in various formats such as VMware, Citrix, KVM, etc. into H3CCAS virtual machines

HA takes into account the virtual machine CPU, memory, I/O throughput load factors and the virtual machine’s affinity to the physical host to dynamically adjust the distribution of business loads and improve system availability.

DRX takes into account the virtual machine CPU, memory, I/O throughput load factors and the virtual machine’s affinity to the physical host to dynamically adjust the distribution of business loads and improve system availability.

NO.60 Which of the following statements about DRS function is correct?

The host uses local storage to store virtual machine files. When the performance exceeds the set threshold, DRS can be triggered and the virtual machine migration can be completed.

DRS prioritizes migrating services with smaller loads

DRS can achieve cross-cluster migration

DRS can dynamically expand new virtual machines

NO.61 The following statement about modifying a virtual machine is correct:

After the virtual machine is created, the display name cannot be modified.

All types of virtual hard disks support online addition and expansion.

You can set the virtual machine to start with the host, but this function becomes invalid after HA is enabled.

After the virtual machine is created, you can add hard disks, network cards and other devices to the virtual machine

NO.62 The virtual machine backup reported an error. The reason cannot be:

Insufficient storage resources in the path of the virtual machine backup directory

The time set by the backup policy has been exceeded

Insufficient storage resources in the virtual machine backup temporary directory

Virtual machine backup priority is too low

NO.63 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

NO.64 After the CVK host restarts, the reason for the fence restart error is TCP disconnected with other nodes, so the reason needs to be eliminated:

Management Network

Business Network

Storage Network

Migration Network

NO.65 Which of the following statements about virtual devices of virtual machines is correct?

The “custom” working mode of the virtual CPU can provide the best migration compatibility and best performance for the virtual machine.

When the virtual machine uses a “virtio hard disk” or a “virtio” network card, it is not necessary to install the virtio device driver

Compared with “normal network card”, “virtio network card” has better performance. It is recommended to use “virtio network card”

The virtual CPU of the virtual machine uses physical CPU resources through time slice polling

NO.66 Which of the following options are indicators of storage product performance:

Bandwidth

IOPS

Maximum number of supported servers

Maximum number of luns supported

NO.67 Which of the following descriptions of the life cycle of a virtual machine is correct?

The virtual machine does not have CAS Tools installed, and the virtual machine may not be shut down when the shutdown operation is performed.

When the virtual machine is working normally, performing a power off operation may cause the virtual machine operating system and application data to be lost, so it should be used with caution.

During the normal operation of the virtual machine, if the storage pool where the image file is located is full, the virtual machine will become suspended

After a virtual machine is moved to the recycle bin, it can be manually restored within the storage period. If the storage period exceeds the limit, it will be automatically deleted.

NO.68 Which of the following statements about configuring a virtual switch is incorrect?

The uplink port of the virtual switch allows all VLANs to pass

The virtual switch uses the vNer0 port of the virtual switch, and the port is configured with VLAN 100. Then the physical switch port connected to the virtual switch must allow VLAN 100 to pass through, otherwise the virtual machine cannot communicate with the external network.

When adding a virtual switch, you must bind a physical interface, and when binding multiple physical interfaces, you must configure link aggregation mode and responsibility sharing mode.

The storage virtual switch must be configured with an IP address, otherwise the CVK host cannot mount the IP SAN storage through the storage virtual switch.

NO.69 Which of the following statements about virtual machine cloning is incorrect?

Virtual machine cloning methods include normal cloning, fast cloning and full cloning.

Cloning is only allowed within the same CVK host

The cloned virtual machine has the same operating system, application system and data as the original virtual machine, and the MAC address of the virtual network card is also the same.

The default IP address acquisition method for the cloned virtual machine is DHCP, so there will be no address conflict problem
