H13-629_V2.5 Exam Dumps - HCIE-Storage V2.5

Check if the size of the migrated file is the same as the original data.

Check if the number of documents corresponds to the original data

Check if each file with read and write permissions corresponds to the original data

Whether the time for reviewing the case file corresponds to the original data.

OLTP database generally have a large number of random write, it is recommended to choose RAID 10 to store data.

In order to improve write performance, all SQL server database data stored in the LUN write strategy is configured to "write back the image".

Because the size of the SQL server page is 8K, in order to ensure the best performance of the database, NTFS allocated block size should not be less than 8KB.

SQL Server database instance memory size and recovery mode of choice has no effect on the performance of the database.

Reduce the number of snapshots.

Reduce the number of virtual machines per LUN.

Increase the number of LUNs and limit the number of hosts accessing the same LUN.

Change the type of virtual disk created.

It is an object-based approach to data replication

ROW snapshots are based on the cyclical manner of data replication

It can be manually set off by the user or system timing synchronization starting

It supports the Quota quota information of the main file system to the slave, no need to configure the quota.

False

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

Disaster recovery side of the data stored in the cache, not yet 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, and the incremental data link is abnormal during the synchronization.

VxFS is a non-log file system that can support more than 2T files.

File system snapshot using copy-on-write (copy-on-write technology) and other files together, share partition or volume storage space.

Provide file system-level snapshots, copy.

File System Snapshots, Scenarios, Replication, etc. Features are based on Storage Checkpoint.

Create a partition read and write cache the same size

When a file is in the locked state, the file protection duration can be manually prolonged or shortened.

A locked file will shift to the expired state if the file system WORM clock value is greater than the file atime value.

After the WORM file system compliance clock has exceeded the file expiration time, an appending file will shift from the appending state to the expired state.

Only files of 0 byte can shift from the locked state to the appending state.

The shared disk file system uses the GPT format that caused the quorum disk to fail Online

The quorum disk can not be online due to the cluster feature that does not enable multipathing software

The MSCS Cluster service does not bring the volume resource online. The resource disk can not be online

Heartbeat network timeout causes arbitration disk and resource disk probability online

In the backup parameter settings "max open files" parameter defines the maximum number of files to be read in parallel per channel, which is the RMAN MAXOPENFILES parameter

"Command line backup" and "Log Backup" select the storage strategy for the database and archive logs, both need to choose the same storage strategy

The "data files per BFS" parameter in the backup parameter settings specifies the number of data files that can be simultaneously written to the same Back Set number

To achieve Oracle RAC table-level recovery, the backup parameter settings must be in the "option" tab check the "enable table browse "option

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

Disaster recovery data stored in the Cache, not yet 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 recovered

When the node a is found through the sms -v command, the status of the IPStor Authentication Module is FAIL. The service of the node A will be from Move to Node B.

unplug the A node power supply, A node's business will automatically switch to the B node

unplug the A node and the backup server network connection, the A node's business will automatically switch to the B node

A, B nodes can work in Active-Active mode, but can only manually achieve the backup service load balancing between A and B nodes

CIFS does not allow multiple clients to access

The CIFS client writes the shared file and does not write to the storage system immediately. Instead, the file is saved in the local cache and can be read againImprove read rate, improve performance

CIFS does not support anonymous transmission and shared authentication access

CIFS supports a variety of character sets to ensure CIFS can be used in all language systems

The SIR cluster of the VTL6900 supports global deduplication

The deduplication start time of the VTL6900 can be controlled automatically according to the policy

VTL6900 on the specified tape deduplication and remote replication is recommended at the same time

VTL6900 deduplicated tape to do data archiving, the physical tape library in the NC is still non-deduplicated data

Need to understand the business (applications and data, etc.), clear the goal of tuning.

After tuning all the system configuration parameters related to performance bottlenecks, judge whether the tuning goal is completed.

Back up business systems and data before tuning.

Monitor and analyze performance data by business processes, identify performance bottlenecks and analyze root cause.

Snapshot file system can be dedicated as a separate space to the client.

For a file system can create multiple snapshots, support snapshots of the snapshot

Snapshot file system provides only read-only access to external, it cannot provide write operations

File System Snapshot Instantly copy the source file system completely available copy, when due to viruses or man-made misuse and other causes of the original file system is not available, the rollback of the snapshot can restore the original file system.
