A. Create a virtual snapshot of the slave LUN and activate it, then map the snapshot LUN to the host for authentication.

B. After the snapshot LUN is mapped to the host, the host can read and write the snapshot LUN.

C. After the verification is completed, stop the upper-layer service application, release the LUN mapping, and finally delete the snapshot.

D. Stop the snapshot before the host can write snapshot LUN.

What is correct about the reconstruction of the Huawei OceanStor V3 storage system? (Multiple choice.)

A. It can quickly recover valid data, not updated data does not need to be restored.

B. Complete reconstruction requires data difference log information.

C. Recovery Refactoring uses a scenario where the disk can not be used for downgrade.

Which statement is false about the erasure code N+M redundancy implemented by Huawei OceanStor 9000?

A. Different empty directories can be assigned different data protection levels to protect the data that will be stored in these directories.

B. Data written to an OceanStor 9000 is first divided into chunks at a size of 4 GB if the data size is larger than 4GB.

C. The erasure code algorithm calculates M parity chunks for every N consecutive chunks.

D. The utilization rate of storage space under protection is about N/(N+M), and data reliability is determined by M, where a larger value of M results in higher reliability.

A. True

B. False

Which description of OceanStor V3 storage system tuning process is incorrect?

B. After tuning all the system configuration parameters related to performance bottlenecks, judge whether the tuning goal is completed.

C. Back up business systems and data before tuning.

D. Monitor and analyze performance data by business processes, identify performance bottlenecks and analyze root cause.

A customer production center is in Chengdu with a disaster recovery center in Shenzhen, using VIS 6600T remote replication capabilities to meet the remote disaster recovery. Which of the following about the VIS6600T copy function is correct?

A. DCM (data change map) is mainly used to ensure that the data in the production center is copied to the disaster recovery center according to the order sent by the host to ensure the data consistency

B. Production, disaster recovery data volume and disaster recovery must be consistent, the name can be inconsistent

C. Each business configuration a copy volume group, multiple copy volume group can use the same virtual IP

D. virtual IP and physical IP must be in the same network segment

An MSCS Two-Node Cluster Interconnects with Disk Arrays via the iSCSI Protocol in a Multipathing Environment and Multipathing Software installed on Each Node. You build the cluster configuration using the wizard and part of the description shows that the quorum disk and resource disk can not be online. The following statement is correct regarding this scenario:

A. The shared disk file system uses the GPT format that caused the quorum disk to fail Online

B. The quorum disk can not be online due to the cluster feature that does not enable multipathing software

C. The MSCS Cluster service does not bring the volume resource online. The resource disk can not be online

D. Heartbeat network timeout causes arbitration disk and resource disk probability online
