Port link-type trunk

Port trunk allow-pass vlan 16 17

According to the above configuration, the following statement is correct (D)

A virtual machine can have multiple virtual network adapters at the same time, corresponding to different virtual switches.

In Huawei FusionCompute, the resources of the cluster are composed of the host and its associated storage and network resources.

Virtualization is divided into computing virtualization, storage virtualization and network virtualization, corresponding to cloud computing cloud host, cloud storage, cloud network

A, yes

B, wrong

As FusionCompute, which one of the following options do not belong CPU resources QoS parameters?

A, CPU share of resources

B, CPU resource limits

C, CPU resource reservation

D, CPU resource reuse

What does not reflect the features of cloud computing on-demand self-service in the following options are

In Huawei FusionCompute, which of the following actions takes effect immediately?

In Huawei FusionCompute, the following incorrect description of port groups and security groups is D

A A virtual machine NIC is connected to a virtual port in the port group, and a virtual machine NIC is associated with a security group

A B-port group is a collection of one or more virtual ports on a DVS, while a security group is a collection of one or more rules

C. A DVS can have multiple port groups and a VM can be protected by multiple security groups

D. Security groups are based on port groups to protect virtual machines /// virtual network cards

The memory and CPU resources used by virtual machines in Huawei FusionCompute can only be provided by the same cluster. Therefore, the maximum available computing resources for virtual machines cannot exceed the sum of resources available to all hosts in the cluster A. TRUE

B. FALSE

The SAN provides the host with a "bare disk" without a file system. What file system is built on it depends entirely on the host's operating system. B

A TRUE

B FALSE

The following are the north-south traffic (multi-select)

Templates can be used to quickly deploy virtual machines. Currently, templates can only be made by converting or cloning virtual machines.

Cloud computing quantifiable services refer to charging customers based on time and volume of use.

In Huawei FusionCompute, the operation of creating a disk using IP SAN includes

Create storage resource

2. Add a storage port on the host

3. Add a data store

4. Create a disk

The correct sequence of operations is

In Huawei FusionCompute, if a virtual machine is bound to a host, the functions that will be affected are (multi-select) .

It is found in FusionCompute that the IP address of a Windows virtual machine is 0.0.0.0, the possible reason is

In a Linux virtual machine. The one who can manage the logical volume is B

A OVM

B LVM

C PVM

D DVM

The following description of distributed storage is correct

A virtual machine generally has a corresponding configuration file, which records the specifications, name and other information of the virtual machine. A

The following description about RAID is correct (multiple choice) BC

Which of the following technologies can increase the link speed on the switch?

For FusionCompute, the incorrect description of the hardware of the bare device is ()

Which of the following is not a feature of big data 4V

NUMA is a memory architecture designed for multiprocessor computers. Memory access time depends on

Processor location, under NUMA, the processor accesses its own local memory faster than non-local memory (the memory is located in

Another processor, or shared memory between processors) is faster.

In Huawei FusionCompute, the following incorrect technical description of CPU QoS is (C)

A The role of "reservation" is to ensure the lower limit of the computing power of the virtual machine, that is, how much resources are used at least

B "Shares" is used to calculate resources based on the relative CPU share values ​​of multiple virtual machines when computing resources are insufficient.

Source balance and adjustment

C "limit" is used to specify the maximum number of hosts

D By adjusting the "Reservation", "Share", "Restriction", to achieve control of the virtual machine CPU resource usage

In Huawei FusionCompute, what is incorrect about the IMC function description is

It is recommended to enable the IMC function when the CPU models of the CNA hosts in the cluster are inconsistent.

B Enabling IMC cannot ensure that the virtual machine is successfully migrated between hosts with different CPU models.

C IMC only supports migration from lower version CPU feature set to higher version

It is recommended to enable the IMC function when the main frequency of the CNA hosts in the cluster is inconsistent.

Both CPU resource QoS and memory multiplexing technologies use different strategies to rationally allocate resources

In FusionCompute, the administrator binds the two network adapters of the CNA host in the active / standby mode. After binding, the transmission rate is equal to the sum of the transmission rates of the two network ports.

Cloud computing is the product of the development of the Internet and computing technology, so cloud computing must be inseparable from the network
