Can not save transmission bandwidth.

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:

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

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

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

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

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

In the Huawei backup solution, Server-Free backup networking involves snapshot technology, which component initiates the snapshot creation Build order.

Production storage D. Backup media

In a backup structure with a primary backup domain and multiple branch backup domains, the following description is wrong:

The main backup domain actively collects metadata of each branch backup domain on a regular basis. After the connection network between the branch backup domain and the main backup domain is interrupted and restored, Metadata transmission can be automatically repaired.

Integrate multiple branch backup domains into one primary backup domain, and centrally view the operation reports of each backup domain in the primary backup domain.

Each branch backup domain operates independently, and the connection network failure with the main backup domain does not affect the backup job of the branch backup domain.

The main backup domain actively collects metadata of each branch backup domain on a regular basis. After the connection network between the branch backup domain and the main backup domain is interrupted and restored, Metadata transmission can be automatically repaired.

Register the remote client as an unconfigured client in the primary backup domain. The clients can be hidden and grouped.

Colleagues customized Huawei dual-active disaster recovery solutions for customers. Customers already have a set of OceanStor S5500TV2 and a set of third-party systems.In the storage system, the two sets of equipment are placed in two data centers to implement activeactive disaster recovery. The solution:

Not feasible. The active/standby disaster recovery solution requires at least a set of OceanStor V3 storage.

Not feasible. The active and standby disaster recovery solution requires at least a storage system of OceanStor 5300 V3 and above.

Feasible, the storage device meets the requirements of the active-active disaster recovery solution.

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

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

Capacity and storage strategy design->Backup and archive strategy design->Backup system migration design

Backup system migration design?>Capacity and storage strategy design?>Bandwidth and network design

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

For a replication consistency group in a normal state, before performing a master-slave switchover, what operations need to be performed on the replication consistency group? indivual?

Cancel write protection from the end

Adjust the recovery strategy to manual

Switch directly without any operation

The correct statement about the HyperMetro arbitration server model is: (multiple choice)

In the arbitration server mode, when the heartbeat between the storage arrays is interrupted, the arrays at both ends initiate an arbitration request to the arbitration server, and the arbitration server is The server comprehensively judges which side wins. The party that wins the arbitration continues to provide services, and the other party ceases to provide services.

In the arbitration server mode, if there is a requirement to obtain arbitration first, the site priority can also be configured.

A set of arrays and arbitration fail at the same time, and the surviving arrays continue to run services.

In the arbitration server mode, when the heartbeat between the storage arrays is interrupted, the arrays at both ends initiate an arbitration request to the arbitration server, and the arbitration server is The server comprehensively judges which side wins. The party that wins the arbitration continues to provide services, and the other party ceases to provide services.

The arbitration fails, and the heartbeat link between the arrays is interrupted, and the service is not affected.

In the arbitration server mode, if there is a requirement to obtain arbitration first, the site priority can also be configured.

Which one of the following statements about synthetic full backup is wrong? (single choice)

The recovery time is longer than the full backup time.

On the backup server or media server, combine the previous full backup and other incremental or differential backups to generate a full backup.

Since the full backup is generated on the backup server, there is no pressure on the application server.

The backup space occupied is as large as the full backup.

The recovery time is longer than the full backup time.

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

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.

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.

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.

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

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.

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