Regarding the four disaster recovery modes of HyperMetro, Hot Standby, Warm Standby, and Cold Standby, is the following statement wrong?
- A. 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.
- B. 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
- C. 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
- D. 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
正解: C
解説:
Analysis: The warm standby technology is implemented on the basis of the active and standby data centers, provided that there are two active and standby data centers.
The standby data center is deployed for warm standby, and application services are responded to by the primary data center.
When the service is unavailable, it is necessary to realize the overall switching of the data center within the specified RTO time. When realizing the main data When the center switches, it is necessary to disconnect the main data center routing link and connect the backup data center routing link to ensure the same time There is only one data center online. The warm-up technology is still a manual method, and someone needs to be on duty 24 hours to complete the operation.
The work effect is low.
