H13-629 practice questions, page 19 of 20, with answer review and explanations.
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. 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
Question 92
RAID2.0 has the natural advantage of supporting the smart tier, to accelerate the performance of hot data. Which of the following surface description 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 93
In the OceanStor 18000 storage system, a 15K RPM SAS disk is used. Assuming that the average seek latency of this type of disk is 6 ms. This type of disk can provide a single disk IOPS.

Question 94
Huawei OceanStor storage controller BBUs are both 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 95
The client environment is the HP-UX11i v2 operating system, the HBA is the AD193A, and the operating system comes with the driver. The storage array is Huawei OceanStor V3, when the LUN mapping between HP-UX and the storage system is completed, you can not change the topology mode of the FC host interface card on the storage system.
