Pass the Huawei HCIE-Storage H13-629_V2.5 Questions and answers with CertsForce

source-side deduplication (backup software)

target-side deduplication (backup software deleted)

Target-side de-duplication (backup software global deduction)

target-side deduplication (backup media deleted)

TRUE

FALSE

scale-out: storage resources on-demand expansion, increase the engine to achieve performance, linear increase in capacity

Full Exchange: The use of PCIE1.0 full switching interconnect, providing sufficient switching bandwidth to meet the stringent performance requirements

Inherent Load Balancing: The controller is alive and well-balanced load sharing to improve storage resource utilization

Full redundancy: Redundancy of all components, intelligent switchover of component failures to meet stringent business continuity requirements

The client must also support the SMB3.0 protocol

If the client has only one network port, you can not use the SMB3 function

If the client has a GE network port with the same type and number of ports, when the client uses SMB3 to access Huawei OceanStor 900, the client will establish multiple connection channels with Huawei OceanStor 9000

If the client has two or more GE and 10GE IB ports of the same type, after the SMB3 is applied, when one of them is disconnected from the network port, business will be interrupted.

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

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

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 POOL to increase the depth of the points

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

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

True

False

Direct use of the root user, in the case of the file system is mounted fsck repair

Using the owner of the user data file, perform an fsck fix if the file system is mounted

Use the owner of the user data file to perform a fsck fix on the device if the file system is unmounted

Using the root user, perform a fsck fix on the device while the file system is unmounted

Correct
