A. Application of disaster drills mainly switch production business systems to isaster recovery side, exercise disaster environment is properly available.

B. application disaster drills execution is completed, replication relationship will split, disaster recovery side will take over the production system to run the business.

C. drills in the production process can stop the end of normal business, one-click run fast moving business to disaster.

D. disaster drills will automatically stop production applications and on the Device Manager remove the production host to the storage of production map.

A. fixed prefetching is suitable for the database application.

B. smart prefetching is suit for single data flow reading application, or unable to determine whether the reading application is sequentially scene.

C. prefetch not suitable for multi-user multimedia on demand.

D. variable prefetching is suit for fixed-size size sequentially reading application. Such as multi-user streaming media on demand, users use the same stream.

A. msdb

B. pubs

C. tempdb

D. master

A. It is a known du and df command bug, need to upgrade to the latest version

B. mnt directory is in some open files are deleted

C. mnt directory mount the block device abnormal

D. mnt directory also mount another block device

A. Increase the Extent value

B. Reduce the stripe depth

C. Keep the Extent default

A. FALSE

B. TRUE

A. backup media failure

B. media server is offline

C. The client can't resolve the host name of the media server

A. Engineer A deleted the original collection results compressed file, then the results will be collected directory again all the contents of the zip file format for analysis of log analysis tools.

B. Log analysis tool can run on any PC without interoperability with the storage system. The analysis process time depends on the amount of logs, which may take a long time.

C. After the analysis is completed, all the problems caused by the log analysis will be displayed in the list of problems. The "Details" contains the approximate cause of the problem and suggestions for handling the problem.

D. Log Analysis Tools After starting the analysis, due to other reasons, you need to terminate the analysis task, you can click on the analysis tool to abort this analysis.

A. FALSE

B. TRUE

A. When the business pressure is high, you can increase the high water level appropriately, avoid frequently triggering the high-speed brushing, and make the system stable in the middle and low speed brushing.

B. By default, the low watermark value set by the system is 20. In the Oracle OLTP service scenario, the low water level can be appropriately increased to optimize the write performance.

C. The time that IO stays in the Cache is closely related to the setting of the low water level value. When the low water level is set higher, the issued IO can get more integration opportunities, thus improving the performance of random writes.

D. When the write strategy is write-back, the Cache controls the storage capacity and the brush rate of dirty data through the high and low water levels.

A. Target storage OceanStor V5 currently only supports Linux hosts.

B. The host must use Huawei self-developed multipath

C. The migration target LUN and edevLUN home controller need to be the same.

D. Select "Third-party masquerading" in heterogeneous virtualization operations

A. F_Port: The switch connection port is used to connect two N_Ports.

B. E_Port: Cascading port for cascading (ISL) other switches.

C. GL_Port: Universal port, which can switch between FL_Port and F_Port.

D. FL_Port: fabric port used to connect to other devices on the loop ring.
