NEW QUESTION # 360
A securities company, in order to ensure business continuity, plans to establish a disaster recovery structure with three centers in two places. It is designed to ensure that services can be quickly switched in the disaster recovery center in the event of a circuit failure or fire in the production center, so as to maximize the protection of business. continuous operation of the system. At present, the company has deployed a production data center, an intra-city disaster recovery center and a remote disaster recovery center. The general situation is as follows.
1) A production center: Windows/linux operating system, database, etc.,
2) Disaster recovery center in the same city in location A: 100 KM away from the production center;
3) C remote disaster recovery center: 1000 KM away from the production center. The customer requires RPO=0, RTO=0 between data centers in the same city, and the remote disaster recovery center is used as the data-level disaster recovery center, and the data recovery RPO is less than 10 minutes.
Which of the following statements about the construction of three centers in two places in the project is correct? (Multiple Choice)
- A. WDM equipment needs to be deployed between data centers in the same city
- B. The storage capacity and LUN configuration planning of the same-city disaster recovery center are recommended to be consistent with those of the production center to provide better dual- active performance
- C. In order to meet customer RPO and RTO requirements, the three data centers need to adopt parallel replication (synchronization + synchronization) architecture
- D. Since the customer requires RPO to be less than 10 minutes, the primary data LUN can be initially synchronized to the secondary LUN in full, and then incrementally synchronized to the secondary LUN periodically.
Answer: A,B,D
