NO.250 FusionStorage Block adopts a unique data block slicing technology, and a data routing algorithm based on DHT Hash, which can evenly distribute the data of the volume to the fault domain of a larger resource pool, so that each volume can get larger The IOPS and MBPS performance also makes the load of each hardware resource relatively balanced.

True

False

NO.251 In the Huawei Oceanstor 9000 system, which of the client types supported by NFS sharing is not included?

Host name

IP address

Net group

AD domain

NO.252 The Erasure code redundancy technology used by Oceanstor 9000 supports higher reliability and more flexible redundancy strategies than traditional RAID algorithms. Which of the following description about the principle of Erasure code N+M is wrong?

When data is written, it is cut into N data blocks with the same size

For every N consecutive data blocks, M check blocks are calculated through the Erasure Code algorithm (M<N)

Check blocks (M<N)

In the Erasure code storage mode, the system supports up to N hard drives

NO.253 An enterprise adopts Huawei OceanStor hybrid flash storage for multi-select storage. In order to facilitate management, the administrator uses SmartQuota technology to create different Quota Trees on the root directory for separate use by departments A, B, and C.
Which of the following statements about setting the quota type are correct? (Multiple choice)

You can set the default directory quota on Quota Tree

You can set user quotas on Quota Tree

You can set directory quota on Quota Tree

User group quota can be set on Quota Tree

NO.254 Which of the following statements about the Thin LUN and multi-select Thick LUN of Huawei Oceanstor storage are wrong? (Multiple choice)

Both Thick LUN and Thin LUN need to be configured with initial capacity

Both Thick LUN and Thin LUN can be configured in the same storage pool

Both Thick LUN and Thin LUN can be greater than or equal to the available capacity of the storage pool where they are located

Both Thick LUN and Thin LUN can be created in batches

NO.255 In the software architecture of Huawei OceanStor 9000, the distributed object storage layer is built based on the distributed file storage layer.

TRUE

FALSE

NO.256 Which of th e following statements about data protection functions provided by Hu awei OceanStor 9000 is false?

Huawei OceanStor 9000 uses the erasure code technique to provide N+M redundant storage of data.

Huawei OceanStor 9000 uses the mirroring technique to provide redundant storage of metadata.

If physical domains are used, the failure of a disk or node in one domain will deteriorate the data reliability of other domains or even cause data loss.

If the protection level is N+1, a cluster requires a minimum of three nodes.

NO.257 Huawei OceanStor 9000 provides a single file system, offering a unified file system namespace.
Which of the following statements about the unified file system namespace provided by Huawei OceanStor 9000 is false?

During the startup of the OceanStor 9000, a namespace is automatically created and its name is the same as that of the OceanStor 9000.

As the root directory of the entire system, a namespace cannot be shared or accessed. However, its subdirectories can be shared and accessed.

The unified namespace provides a unified storage resource pool where storage space can be centrally managed and allocated.

All shared directories are subdirectories in the unified namespace.

NO.258 In a large and medium-sized database application, files such as data, logs, and modification records are stored in the associated LUN1, LUN2, and LUN3 respectively, and remote replication tasks 1, 2, and 3 are created respectively, and the engineer copies these three remotely The task is added to the consistency group.
In this case, which of the following statements are correct? (Multiple choice)

If remote replication task 2 fails during data synchronization, the consistency group will immediately stop remote replication tasks 1 and 3

These three groups of remote replications can only be added to the consistency group on the primary storage system, and all the secondary LUNs of the remote replication must be located on the same remote storage system

If remote replication task 2 fails during the data synchronization process, the consistency group will continue to complete remote replication tasks 1 and 3, and after the troubleshooting is restored, continue to perform remote replication task 2 data synchronization

After a disaster occurs, use the secondary storage system to recover data, and the data in the database is still valid

Cabinet parameters

Cabinet power system

NO.260 Huawei Oceanstor 9000, the client processing the write request will fragment the data according to the protection level specified by the file, write the data fragments to the power-saving memory on the corresponding node, and then calculate the verification data by each node. And write to the power-saving memory of each node. After all nodes write to the power-saving memory successfully, the write operation is successful.

True

False

NO.261 A company has purchased multiple sets of Huawei distributed storage, deployed in multiple data centers, and used object service remote replication to build a disaster recovery system. These distributed storages are planned in the same area, so this area has and only a default cluster, other clusters are non-default clusters.

True

False

NO.262 Users of HuaweiStorageSystem A are requesting higher performance for their OLTP application. The OLTP application is the only system using HuaweiStorageSystem A.
A colleague suggests improving performance by running SmartQOS on the LUNS involved, while decreasing the performance of other services:
This is;

Not a solution to the problem, the other services will no longer work correctly.

A solution, but not the best solution; SmartPartition would be better.

A good solution for the problem; performance will improve.

Not a solution for the problem, since there will be only one queue of I/O.
