Which of the following is not a disaster recovery manual restart configuration necessary to restore the production system (Multiple choice.)

Question 91

When the database is protected and the virtual snapshots are used from the end to verify LUN data consistency on the production end and the disaster recovery end. However, the disaster recovery end of the LUNd database can not be started normally. What is the possible reason? (Multiple choice.)

After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated at the same time.

Disaster recovery storage side of the database resides in the cache has not been written to the hard disk.

When creating a snapshot on the disaster recovery end LUN, the production end is copying data to the disaster recovery end.

The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy. The incremental data is abnormally interrupted during the synchronization process and has not been repaired.

Question 92

RAID2.0 has the natural advantage of supporting a smart tier, to accelerate the performance of hot data. Which of the following descriptions about the smart tier performance is correct?

When smart LUNs act as backup media, smart tier's performance improvement on this LUN is not obvious.

During the running of the business, the extent size can be adjusted by the size of the hotspot area to obtain better performance.

Literacy ratio in the 1:9 scenario, enabling the smart tier has greatly improved the performance of the business.

Smart tier has no effect on host performance during hot data migration.

Question 94

Huawei OceanStor storage controller BBUs are both in a fault alarm. Which description is correct for the upper application?

System does not work.

If the device is powered off unexpectedly, some of the business data will be lost.

Business performance is not affected.

Upper business IO read and write will not have any impact.

Question 96

In an HPUX system, you use the lv image lvreduce or lvsplit command / dev / vg01 / lv - test within a mirror. Which command will test the implementation of the following command lvsplist / dev / vg01 / lv -, using vgdisplay-v system to see what the lv is.

Question 97

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

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

Complete reconstruction requires data difference log information.

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

In the event of a sudden disk failure recovery reconstruction.

Question 98

A user performs the following operations on an OceanStor 9000:

Create a user group named Group01 and sets a quota for Group01 in the /home/aroup0t directory as follows: Recommended threshold: 10 GB Soft threshold:15 GB.Grace period: 10 daysHard threshold: 20 6B

Question 99

A TV station plans to adopt Huawei OceanStor 9000 as a back-end storage system, with 10 OceanStor 9000 C nodes, planned to be deployed in 4 standard cabinets, with all backends connected to a pair of stacked back-end CE6850 switches. There is no single customer in the existing networking standalone management network. Which of the network IP address planning described below is incorrect?

You can plan back-end storage network for 9000 internal communications, without planning gateway address, and front-end network with the same network segment IP address.

Oceanstor 9000 front-end network and management network can be considered together, planning for the same network segment.

Back-end CE6850 switches need to use four stacked cables for stacking connection to ensure bandwidth requirements

The external NTP server address and the OceanStor 9000 front-end network need to communicate to ensure that the OceanStor 9000 system and client applications maintain time synchronization.

Question 100

Which of the following is not a disaster recovery manual restart configuration necessary to restore the production system (Multiple choice.)

Stop the current production business

Add the remote device to the original production array

With the disaster recovery array as the master LUN and the original production array as the slave LUN, create the remote replication relationship between theDR and the production end and wait for the initial synchronization to becompleted.

Make an incremental synchronization.

Delete the original production array consistency group.
