NEW QUESTION # 68
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. synchronous replication over dual data centers via Metro Ethernet
- B. asynchronous replication over geographically dispersed dual data centers via CWDM
- C. synchronous replication over geographically dispersed dual data centers via MPLS
- D. asynchronous replication over dual data centers via DWDM
Answer: A
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 # 82
Company XYZ is planning to deploy primary and secondary (disaster recovery) data center sites. Each of these sites will have redundant SAN fabrics and data protection is expected between the data center sites. The sites are 100 miles (160 km) apart and target RPO/RTO are 3 hrs and 24 hrs, respectively. Which two considerations must Company XYZ bear in mind when deploying replication in their scenario? (Choose two.)
- A. VSANs must be extended from the primary to the secondary site to improve performance and availability.
- B. Synchronous data replication must be used to meet the business requirements
- C. Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.
- D. VSANs must be routed between sites to isolate fault domains and increase overall availability.
- E. Target RPO/RTO requirements cannot be met due to the one-way delay introduced by the distance between sites.
Answer: B,D
Explanation:
synchronous data replication must be used to meet the business requirements, is incorrect. As described above, asynchronous replication would be a better choice in this scenario due to the distance between the data center sites and the target RPO/RTO requirements.
asynchronous data replication should be used in this scenario to avoid performance impact in the primary site, is correct. Asynchronous replication would allow Company XYZ to meet the target RPO/RTO requirements while avoiding the performance impact of synchronous replication.
