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