NEW QUESTION # 140
An architect receives a business requirement from a CTO that states the RTO and RPO for a new system should be as close as possible to zero. Which replication method and data center technology should be used?
- A. asynchronous replication over geographically dispersed dual data centers via CWDM
- B. asynchronous replication over dual data centers via DWDM
- C. synchronous replication over geographically dispersed dual data centers via MPLS
- D. synchronous replication over dual data centers via Metro Ethernet
Answer: C
Explanation:
RTO and RPO are measures of how quickly and accurately a system can be recovered after a disaster or failure. RTO refers to the amount of time it takes to restore a system to its normal operation after a failure, while RPO refers to the amount of data that can be lost as a result of a failure. In synchronous replication, data is written to both the primary and secondary systems at the same time. This ensures that the data on the secondary system is always up-to-date and ready for use in the event of a disaster or failure. Geographically dispersed dual data centers refer to two data centers that are located in different geographical locations, which can help to reduce the risk of a disaster or failure impacting both data centers at the same time.
NEW QUESTION # 141
