In a data backup management system, in the case of low requirements for backup performance, it is not necessary to configure media services separately

The media server module and the management server module can be installed on the same physical server.

A.

True

B.

Wrong

What is the main difference between using synchronous remote replication and asynchronous remote replication in the Huawei disaster recovery solution?

A.

RTO

B.

RPO

C.

Availability of disaster recovery data

D.

Copy link

After testing, the bandwidth of the two data centers of the customer is 155Mbit/s, the peak write bandwidth of an application is 9.8MB/s, and the average

The write bandwidth is 300KB/s, the average write I/O size is 4KB., and the bandwidth utilization rate is 70%. Colleagues choose active and standby synchronous remote replication for disaster recovery

Scheme, the scheme:

A.

Not feasible, 200Mbit/s is required to calculate the bandwidth.

B.

Not feasible. The primary and standby synchronous remote replication disaster recovery solution requires that the bandwidth utilization rate must be >80%.

C.

Not feasible. The primary and standby synchronous remote replication disaster recovery solution requires that the write I/O size must be less than 2KB.

D.

Feasible, because the conditions meet the requirements of the primary and standby synchronous remote replication disaster recovery program.

The backup plan design process is divided into multiple stages. Which of the following stages is in the correct order?

A.

Demand analysis->Information collection-→>Backup and archiving strategy design-→>Bandwidth and network design

B.

Capacity and storage strategy design->Backup and archive strategy design->Backup system migration design C. Backup system migration design→>Capacity and storage strategy design→>Bandwidth and network design

C.

Capacity and storage strategy design-→>Backup and archive strategy design→>Other feature design

Among Huawei's many disaster recovery solutions, which of the following scenarios can eReplication be used? (multiple choice)

A.

Primary and standby disaster recovery

B.

3DC

C.

Data center active-active

D.

Local high availability

During data backup, in order to save space, single-selection data may be deduplicated, such as repeated data block A and

For block B, only one copy of data is physically saved, and the index corresponding to block A or B will be deleted.

A.

True

B.

False

The following features of HUAWEI cloud storage include: (multiple choice)

A.

Deployment is relatively simple for end customers

B.

End customer investment is small

C.

The network cost of backing up to cloud storage is low

D.

Easy to expand

Which of the following descriptions are correct about the data backup strategy? (Multiple choice)

A.

Any backup needs a full backup as the basis

B.

Differential incremental backup can minimize the use of backup space

C.

Differential incremental backup refers to the backup of the differential data between two backups

D.

Synthetic backup has advantages over incremental backup and recovery time in the same scenario

In the Huawei disaster recovery solution, at which levels can data replication be performed? (multiple choice)

A.

Host-based replication

B.

Based on network layer replication

C.

Based on storage layer replication

D.

Copy based on the file system layer

Regarding deduplication on the target side, which option is incorrect in the following description?

A.

The data block is transferred from the source end to the target end, and the deduplication operation is performed on the target end.

B.

Do not occupy the resources of the source.

C.

Target end deduplication is equivalent to post-processing deduplication (Post-processig).

D.

Can not save transmission bandwidth.

Regarding the storage layer data replication disaster recovery technology, which of the following statements is correct?

A.

Install dedicated data replication software on the server.

B.

Reduce the impact on server performance: Compatibility requirements are relatively high, and options are small.

C.

Mature technology, large selection area, small connection distance limit, and high stability.

D.

Less investment and good compatibility. Affect server performance.

The recommended scenarios for installing iDA in a virtual machine are: (multiple choice)

A.

The storage is directly connected to the virtual machine

B.

The storage is directly connected to the ESXi host

C.

The virtual machine contains a large database

D.

There are a lot of files in the virtual machine

Regarding HyperMetro static priority arbitration mode, multiple choices are correct: (multiple choices)

A.

When an inter-array link failure occurs, or a non-priority site fails, the LUN on the priority site continues to provide services, and the non-priority site

The point LUN stops providing services.

B.

When the priority site array fails, the non-priority site will automatically take over the active-active service.

C.

When the priority site array is actively powered off for maintenance, the non-priority site array immediately takes over all active-active services and the services will not be interrupted.

D.

The static priority mode has higher reliability than the arbitration server mode.

In the Huawei dual-active disaster recovery solution, the peak write bandwidth of an application needs 10MB/s, and the average write bandwidth needs 200KB/s.

A.

A.10MB/s

B.

B.200KB/s

C.

C.2.23MB/s

D.

D.114.3Mbit/s
