Question 602

The following description of the Huawei OceanStor backup solution, which one is wrong

Compared with disaster recovery, the recovery granularity of backup is finer, files can be used as the recovery level, and multiple recovery versions can be made.

If the format of the source data and the backup data are the same, the backup data can be directly read and written by the host.

The backup software can back up data to tape for offline archiving.

Question 603

In the HyperMetro active-active data center solution, if there is a bad block on a member LUN of an array, the following statement is incorrect Which is it?

When repairing a bad block, you must first apply for read permission and confirm the local read permission of the active-active pair.

When reading the local LUN of the array, if the bad block is read, if the error cannot be repaired, the host read error message will be returned.

When reading the local LUN of the array, after reading the bad block, if the error is repairable, return the read data to the host to ensure Fast return of host response.

When reading the local LUN of the array, after reading the bad block, if the error cannot be repaired, the system will The data is repaired.

Question 604

In the HyperMetro active-active data center solution, if there is a bad block on a LUN of an array member, the following statement is incorrect.

Which one?

When repairing a bad block, you must first apply for read permission and confirm the local read permission of the active-active pair.

When reading the local LUN of the array, after the bad block is read, if the error cannot be repaired, the host read error is returned information.

When reading the local LUN of the array, after reading the bad block, if the error is repairable, return the read data to the host to confirm Ensure that the host responds quickly.

When reading the local LUN of the array, after reading the bad block, if the error cannot be repaired, the system will The data is repaired.

Question 608

Huawei's end-to-end active-active data center solution is divided into 6 logical levels, namely storage layer, computing layer, application layer, and network layer.

Network layer, transport layer and security layer, the design points of each layer include: (multiple choice)

The security layer provides security protection functions such as FW and IDS of the data center through the Huawei USC series.

The storage layer optimizes the standard 1 write I/O 2 round trips to 1 round trip through the FastWrite function to improve write performance.

The computing layer adopts virtualization platforms such as Huawei FusionSphere and VMware to provide cross-data center large cluster technology to meet the needs of enterprises A variety of key business dual-active requirements.

The transmission layer uses dispersion compensation and other tuning methods to ensure the minimum delay of the transmission layer.
