An enterprise adopts cloud-level primary and backup data-level disaster tolerance. During business planning, two types of storage can be divided according to actual needs.

LUN: Protected LUN and unprotected LUN, create VMs that need disaster recovery on the protected LUN, and configure only the protected LUN

Set up array replication to save the storage space requirements of the disaster recovery center.

Is the following correct understanding of data and information?

Description 1: The file system of the SAN storage is deployed on the storage side, and the file system of the NAS storage is on the host side.

Description 2: Dynamic tiered storage can achieve data migration between storage media with different performance

The data center is an infrastructure built for accessing and carrying server services. According to the business, the data center can be

Divided into: (multiple choices)

Regarding the steps of SAN synchronous replication, what is the correct order?

(1) The production storage receives the host write request. HyperReplication logs the request. Only the place is recorded in the log

Address information, without recording data content.

(2) HyperReplication waits for both the primary LUN and secondary LUN write processing results to be returned. If both are written successfully, clear

Log; otherwise keep the log, enter the abnormal disconnection state, and then copy the corresponding number of the log address again when starting synchronization

According to the block.

(3) Write the request to the master LUN and slave LUN. Normally, the LUN is in the write-back state, and the data will be written

Cache.

(4) Return the processing result of the host write request, which is subject to the processing result of the write master LUN.

OceanStor V3 series storage can only support iSCSI or FC host links separately, not both

Connect to the network.

86. When using the NFS protocol, adding clients and setting read and write permissions have an impact on performance.

Regarding the benefits and necessity of enterprises doing disaster recovery system construction, is the following statement wrong?

Hybrid cloud is a solution that uses both private and public clouds.

A host connected to a switch port cannot belong to multiple zones, but can only be divided into a zone

in.

What are the current challenges of disaster recovery? (Multiple choice)

A company has sufficient client server resources, but network resources are tight. Which deduplication strategy is suitable?

A, file-level deduplication

B. Byte-level deduplication

C, source deduplication

D. Deduplication on the target side

Host-level disaster recovery has less investment and better compatibility.

Among the following options, what is the correct sequence of the basic business configuration process for data center block storage?

1. Create a mapping view. 2. Create a storage pool. 3. Create a hard disk domain. 4. Create a LUN and create a LUN group. 5.

Create a host group. 6. Log in to DeviceManager

A, 6->2->3->4->5->1

B, 6->3->2->4->5->1

C, 3->2->4->5->1->6

D, 4->5->2->3->1->6

When the disk is read and written, the sector is the minimum addressing unit, and a segment can be written to the first half of a sector

Data, and then write a piece of data to another sector.
