NEW QUESTION # 72
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. Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.
- B. VSANs must be extended from the primary to the secondary site to improve performance and availability.
- C. Target RPO/RTO requirements cannot be met due to the one-way delay introduced by the distance between sites.
- D. Synchronous data replication must be used to meet the business requirements
- E. VSANs must be routed between sites to isolate fault domains and increase overall availability.
Answer: A,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.
