When the disk is not accessible, what kind of reconstruction method is used when writing to the disk?
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.

sdb5 directory?
The RTO in the disaster recovery system measurement index refers to the point in time when the system and data must be recovered after the disaster begging.
Statement 1: The higher the number used to indicate the RAID level, the higher the overhead
Statement 2: RAID 10 stripes the data, then mirrors the stripe set.
Incremental backup requires the last full backup and each incremental backup to fully restore data. Data reconstruction is therefore slower compared with full backups.
Multipathing software is only needed in SAN solutions with just a single switch.
Which of the following is the advantage of object storage? (Multiple choice)

Synchronous replication in OceanStor V3 devices is based on the snapshot technology.
Which of the following statements about the differences between DAS and SAN is incorrect?
Statement 1: Virtual Tape libraries allow for a highly scaleable backup strategy as storage can be added later.
Statement 2: Virtual Tape Libraries should be used when remote datacenters are NOT available.
Which of the following operating systems can access CIFS shares without installing additional software?

In a clustered NAS architecture, which of the following allows multiple file system to be consolidated and does not need to be managed separately?
Depending on the amount of data to be backed up, which of the types are actual backup methods?
(Multiple Choice)
Which of the following RAID levels has the lowest hard disk space utilization?
Which of the following are deployment modes of cloud computing? (Multiple Choice)
A backup set is a group of data that is backed up in a batch. A backup set can be used for either full backup or incremental backup.
Bank's bill imaging system often stores structured data on a SAN array, and unstructured data
On the NAS array.
Which of the following are the 3 layers of SCSI Initiator Model? (Multiple Choice)
The process of regenerating all user data and check data on the failed disk in the mirrored array or RAID array is called:
What is wrong with the following statement about disaster recovery drills? ,
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.
You are the storage administrator of a media company that stores a lot of media files such as videos. You are asked to propose a proper storage architecture for a new storage system that stores all the video and graphic files of the company. The requirement is that it could run on commodity hardware in a distributed manner for unstructured data. Choose which one of the following architecture would be the better option.
Statement 1: MLC drives are optimal when used for high intensity writes to that disk.
Statement 2: The latency of SSD drives is about 0.1 s.
There are two descriptions about backups:
Description 1: You can use the data backed up on the tape for data recovery at any time, but you can only recover to the backup moment
Historical data, not the data at the time of failure.
Description 2: Using tape as the backup medium is the highest RTO backup method.
Which of the following is wrong about FC SAN network switching technology?
What is wrong with the following description of DAS?
A, DAS refers to the storage device is directly connected to the server through a SCSI cable or Fibre Channel
B. The data in DAS mode is still scattered, and each application has a set of storage devices. Management is decentralized and cannot be centralized
C. When the server and the storage device are directly connected, new application requirements arise, only for the newly added server
Separate storage device configuration, resulting in repeated investment
D, DAS storage space can be fully utilized, storage devices that can be shared by different application servers, fully
Leverage idle storage space
Description 1: The data recovery of the snapshot depends on the source data. If the source data is physically damaged, it cannot be recovered. and
In this case, the clone can still restore the source data.
Description 2: After the source data is damaged, the LUN copy must completely copy the backup data to restore the source data. And clone only
Damaged data needs to be recovered, which greatly reduces the recovery time.
