Use lossless compression for unnatural images

Can automatically identify unnatural images such as text, Windows frames, lines, etc. in the entire image

Only supports Huawei-specific self-developed image compression algorithms

Lossy compression of natural images such as photos and pictures with an appropriate compression rate

135. Which of the following descriptions about message types and message transmission methods are correct? (Multiple choice)

Broadcast messages can be sent in unicast

Unicast packets must be sent in unicast

Broadcast messages must be sent by broadcast

Unicast packets can be sent by broadcast

136. Which of the following can achieve load balancing among different hosts in the FusionCompute cluster?

DPM

CHA

DRS

137. In Huawei FusionCompute, which one is correct about the description of "role"?

A "role" can have one or more different "operating permissions"

If a "user" has multiple "roles", its "operating authority" depends on the "role" with the highest priority

The "operation authority" of the "role" cannot be modified

A "user" can only have one "role"

138. Setting the port group VLAN ID to 10 in Huawei Fusion Computer represents? (Multiple choice)

De-tag the data frame with VLAN1O tag passing through the port group and forward it

Change the tag of VLAN10 tagged data passing through the port group to VLAN D and then forward it

Discard data frames with non-VLAN10 tags passing through the port group

Label the data frame with VLAN1O tag on the data frame without VLAN tag through the port group and forward it

139. In Huawei FusionCompute, administrators can discover storage devices by scanning or manually refreshing.

141. In Huawei FusionCompute, which of the following descriptions of memory reuse is incorrect?

After memory multiplexing is turned off, the sum of the memory of all virtual machines is less than or equal to the sum of the actual available physical memory

Turning off memory reuse requires that the memory reuse rate of all hosts in the cluster be less than or equal to 100%

The use of memory reuse will degrade the performance of the virtual machine

The administrator can turn on or off the memory reuse function at any time

Hybrid cloud is generally built by operators or cloud service providers, which combines the characteristics of public cloud and private cloud, and is sold or leased for public use

Industry clouds generally have the characteristics of a certain industry, such as large private clouds or small public clouds

Private clouds are generally deployed within the enterprise for use by internal employees

Public clouds are generally built by operators or cloud service providers, and are sold or leased for public use

False

149. Voice recognition, image recognition, and emotional escort robots are all applications of artificial intelligence.

True

False

150. Memory multiplexing technology is the prerequisite for the realization of memory resource QoS.

True

False

Page 16 of 16

True

False

152. Which of the following descriptions can reflect the advantages of virtualization? (Multiple choice)

After using virtualization, the CPU utilization of a physical host can be stabilized at about 65%.

After using virtualization, multiple virtual machines can run simultaneously on a physical host

After using virtualization, multiple applications can run simultaneously on the operating system of a physical host

After using virtualization, virtual machines can be migrated between multiple hosts

153. Which of the following items belong to the underlying virtualization core module provided for the processor in the KVM architecture? (Multiple choice)

kvm.vm

kvm.ko

kvm-amd. ko

kvm-intel.ko
