A. TRUE

B. FALSE

A. Disaster recovery side of the data stored in the cache, not yet written to the hard disk.

B. The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy, and the incremental data link is abnormal during the synchronization.

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

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

A. Device Streams: MediaAgent to storage Media data transfer stream, set in each sub-client

B. The value of Data Reader must be less than the value of Device Streams

C. Data streams: client to MediaAgent data transfer stream, set in the storage strategy

D. data Reader: The flow of raw data read from the client, set in each client

A. should not be arbitrary on the normal operation of the fsck file system

B. By collecting, var / log / message host log information to locate file system failure

C. mount the damaged file system, the direct implementation of fsck to repair

D. Use the mount command to view the file system mount status is read-only

A. Asynchronous replication

B. Simultaneous replication

C. support multiple file system consistency replication

D. Synchronous and asynchronous replication

A. When enabling the snapshot-based backup mode, the NDMP backupfeature requires the file system to support snapshots. Otherwise, the backup task can not be successfully performed.

B. Does not support the system disk backup and recovery operations

C. Based on the snapshot backup, snapshots are created for the current directory. Because the extended attributes of the current directoryreceive the snapshot protection, the current directory extended attributes will be backed up.

D. Does not support the system time zone or other time-related adjustments, does not support daylight saving time.

A. Scenario: Oracle database in the operation of data backup, the data on the LUN bandwidth does not meet the requirements and accompanied by high utilization of hard diskTuning means: the formal creation of POOLto increase the depth of the points

B. Scenario: Sequencing large IO services, especially 1M IO scenarios, with the phenomenon thatthe back-end read bandwidth is much larger than the front-end read bandwidthTuning: Turn off the corresponding LUN prefetch policy

C. scene: the order of pressure reading and writing business conditions, high utilization of hard drivesTuning means: increase the unplug-thresh device hard disk device

D. Scenario: In the case of single concurrent or low concurrent read service, the delay is found to be largeTuning means: change disk unplug 8 Modify unplug - thresh increased from 4 to 8

A. OLAP

B. VDI

C. SPC-1

D. OLTP

A. In the command line configuration, you need to log in to the VTL operating system, the user name is root

B. In the command line configuration management network portdirectory / etc / sysconfig / network-scripts

C. After the command line configuration is complete, you need to restart the network service byrunning the service network restart command

D. The first time you configure and use eth1, you can directly configure the network port IP on the VTL console

A. TRUE

B. FALSE
