Exam 11: HCIE-Storage

A customer wants to deploy one OceanStor v3 storage to meet their capacity and performance requirements. Which of the following should be considered regarding the hard drive configuration? (Multiple choice.)

In Huawei OceanStor 9000, which technologies are used to improve the performance? (Choose three.)

Which of the following is not true about the Huawei OceanStor 18000 Smart Matrix architecture:

A computer center plans to purchase a set of Huawei Oceanstor 9000 products as a follow-up storage system. The requirements are as follows: (1) The minimum storage system needs to provide a total bandwidth of 3-4GB / s (2) storage space can reach 1PB, to meet a single file GB storage (3) computer center room requires control deployed in a cabinet use (4) Internal computer cluster nodes are now all InfiniBand network Based on the above information, which of the following configuration suggestions do you think is more suitable for this project?

In the OceanStor VIS6600T dual-redundant switch network environment, using OceanStor Toolkit inspection found that "multi-path state detection "does not pass the inspection report.  It is found that there are two routes in the 4 paths of the VIS6600T device's 0 node to each LUN of the array. The path status is disabled. According to the analysis, the switch port connected to port 0 of port A0 of node 0 on node 0 of the VIS6600T is visible on the optical switch. The received optical power is much lower than the rated power of the optical module. What actions should be taken to fix this?

OceanStor V 3 storage SmartPatition can allocate independent cache space for different LUNs. The capacity of the cache space is read and write. use.

In an OceanStor V3 system storage array, all the snapshots of a LUN occupy no more space than the LUN.

Using non-deduplication storage based on the disk library strategy, data recovery fails after the data life of the backup has expired.  What is a reason for this?

If you need to automate the DR protection of an Oracle database in Replication Director, the configuration flow is:

Some OceanStor V3 storage resources are mapped to a host as raw devices. The host then creates dedicated file systems on these raw devices. A test tool is used to create a large number of 13 KB files in the file systems. The test tool is also used to read those files randomly for testing the response. In this circumstance, changing the prefetch policy of the tested LUN to constant prefetch and setting the prefetch length to 16 KB can increase the system performance.

The customer needs to create a new OLAP backup database for batch import of online database data at night, and the database software is SQL server 2008. The database file size is 20TB and the storage array is OceanStor v3, which requires a stable write bandwidth of 1800MB / s. What kind of allocation set the most suitable customer requirements?

Using non-deduplication storage based on the disk library strategy, data recovery fails after the data life of the backup has expired:

Two sets of OceanStor unified storage with synchronous remote replication are effective in the following ways to improve host write performance on the primary storage: (Multiple choice.)

Which network connection is wrong for an OceanStor 18000 expansion network?

When using OceanStor V3, you need to mount the file system snapshot to access the snapshot data.

A Huawei OceanStor 9000 is externally shared using NFS and CIFS at the moment. You want to set some parameters to improve the performance of the NFS mounted under the Linux operating system. Which of the following description is correct?

There are multiple types of disks in a hard disk domain in the OceanStor V3 storage system. If you add one SAS disk to the hard disk domain, diagram will be balanced as follows:

In a Huawei disaster recovery plan, in order to implement the one-click disaster recovery operation for Oracle applications, you must configure the recovery in Replciation Director Plan. What configuration actions do you need to do on the Replication Director side before configuring the recovery plan? (Multiple choice.)

Huawei two nodes standard N8500 opened the CIFS service. Which of the following CIFS parameters allows users to view the other users without seeing the headrecord?

On the command line of the N8500 (V200R001) clustered NAS system, you run the NFS> share add rw, no_root_squas / vx / xscmfs command.  Which of the following is correct regarding this?
