Question 425

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

Question 426

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

The initial construction cost of network layer disaster recovery is relatively low, and many manufacturers can provide solutions

Array layer disaster recovery, the arrays at both ends must be products of the same manufacturer, unable to solve the heterogeneous problem

Host layer disaster recovery is implemented on the host side, without considering the compatibility between the underlying devices

Question 427

Regarding the traditional model and cloud computing model, high reliability in the data center and cross-data center disaster recovery methods, the following says What is wrong?

In the traditional mode, the data center relies on component redundancy to achieve high reliability

In the cloud computing mode, the data center relies on component redundancy to achieve high reliability

In the traditional model, cross-data center disaster recovery is mainly based on copying business data, and the recovery process is complicated and the recovery period is long

In the cloud computing mode, cross-data center disaster recovery is the replication of all data in the business data and operating environment.Simple recovery process and short recovery period

Question 428

Regarding the four disaster recovery modes of HyperMetro, Hot Standby, Warm Standby, and Cold Standby, is the following statement wrong?

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.
