Description 1: The data recovery of the snapshot depends on the source dat a. 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.

description 1 is correct, description 2 is correct

Description 1 is right, description 2 is wrong

description 1 is wrong, description 2 is right

Description 1 is wrong, description 2 is wrong

With the advent of the era of big data, the corresponding storage technology is also undergoing changes.Is the following statement correct? (Multiple choice)

The file system develops from a local file system to a cluster file system and a distributed file system

Traditional NAS, facing PB-level data, complex volume management and unbalanced system capacity allocation, will result in waste of resources

The mass storage system is characterized by a more complicated file system and more complicated management

Having large-scale expansion capability is the characteristic of mass storage system

The file system develops from a local file system to a cluster file system and a distributed file system

Traditional NAS, facing PB-level data, complex volume management and unbalanced system capacity allocation, will result in waste of resources

The mass storage system is characterized by a more complicated file system and more complicated management

Having large-scale expansion capability is the characteristic of mass storage system

What are the challenges facing traditional data centers? (Multiple choice)

The following description of disaster recovery is incorrect?

Regardless of whether disaster recovery or backup solutions are used, compared with data during system failure, data for disaster recovery cannot be lost Avoided

After the disaster, I hope to immediately access the backup on the remote device

The restored data hopes to meet the current work requirements immediately

The traditional use of software for data backup still has usage scenarios

The advantages and disadvantages of the disaster recovery technology of the host layer, network layer and array layer, the following statement is correct? (Multiple choice)

For host layer disaster recovery, host layer replication will occupy certain host resources, which will affect the application system

HyperMetro technology can realize that both the main and backup data centers provide services to the outside world. During normal operation, the business of the two data centers can Do load sharing based on weights, there is no difference between master and backup, and respond to some users separately. The weight can be divided by region, or number According to the center's service capacity or external bandwidth

Warm standby technology. When a data center failure causes the service to become unavailable, within the specified RTO time, you can Automatically switch the service to a backup data center

The hot standby business is responded by the main data center. When a data center failure causes the business to be unavailable, the Within RTO time, the service can be automatically switched to the backup data center

The biggest feature of multi-activity is that it will not cause waste of resources in the data center, and the data center carries application business operations.
