H13-624_V5.5 Practice Questions

A.  

When removing the disk, the engineer needs to remove it from its connector, wait at least 60 seconds, and then remove the disk from the chassis.

B.  

Before using SmartKit to replace the disk, the engineer needs to complete the pre-processing as prompted. After that, the engineer can continue the subsequent operations.

C.  

The duration from removing the main storage disk to installing a normal one on the node cannot exceed 10 minutes. Otherwise, heat dissipation of the storage device will be affected.

D.  

The interval between removing the faulty disk and inserting a normal one is at least 10 seconds. Otherwise, the disk may be damaged.

A.  

The internal management network is used for communication between storage and management nodes, including deployment and upgrade, resource configuration, performance alarm reporting, and certificate and key update.

B.  

For the file service in the Distributed Parallel Client (DPC) scenario, the back-end storage network is available for communication with compute nodes to process communication data between the DPC and Object Storage Device (OSD).

C.  

The management network is used for system management and maintenance. It is connected to the customer’s management network.

D.  

The service network is connected to the customer’s application system and accesses the storage through the S3, HDFS, NFS, CIFS, and POSIX interfaces.

A.  

To install the Distributed Parallel Client (DPC), the switch configuration is required before the installation regardless of whether the low level design (LLD)- or wizard-based installation mode is selected.

B.  

To interconnect with FusionCompute during block service installation, storage and compute nodes must be deployed in converged mode, and the management nodes must be deployed in the virtualization environment.

C.  

To interconnect with Huawei Cloud Stack during block service installation, storage and compute nodes must be deployed in converged mode, and the management nodes must be deployed in the virtualization environment.

D.  

To install the file service in the standard protocol scenario, the switch configuration is not required throughout the entire installation process.

A.  

Valid read bandwidth of disks = Read bandwidth of a single disk x Number of disks x (Number of system disks / Total number of disks)

B.  

Valid write bandwidth of disks = Write bandwidth of a single disk x Number of disks

C.  

Valid write bandwidth of disks = Write bandwidth of a single disk x Number of disks x (Number of data disks / Total number of disks)

D.  

Valid write bandwidth of disks = Bandwidth of a single port x Number of ports

A.  

TRUE

B.  

FALSE

A.  

A source LUN and a target LUN form a HyperClone pair, and a source LUN cannot form multiple HyperClone pairs with different target LUNs.

B.  

This feature provides a full copy of the source LUN’s data at the synchronization start time. Hosts can read and write the target LUN immediately, without waiting for the copy process to complete.

C.  

This feature synchronizes data from the source LUN to the target LUN and can also restore data from the target LUN to the source LUN.

D.  

There are significant differences between clone blocks and clone file systems. The former is implemented based on the redirect-on-write (ROW) technology, while the latter is implemented based on the copy-on-write (COW) technology.
