A media company runs a global content distribution platform using Dell ECS. They want to serve read requests from two geographically dispersed regions while allowing writes to occur at either site. The solution must ensure that both sites can accept writes and that data is eventually consistent across sites. Which geo-replication setup best meets these requirements?

Active-active with synchronous replication between sites

Active-active with asynchronous replication between sites

Active-passive with the passive site used only for reads

One-to-one replication from the primary to the secondary site

A cloud service provider uses Dell ECS to offer storage to multiple tenants. They need to protect against disk failures and also provide a disaster recovery option for tenants who require it. The provider wants to minimize storage overhead for tenants who do not require disaster recovery, while offering replication for those who do. Which approach should they take?

Use synchronous replication for all tenants

Use asynchronous replication for all tenants

Use erasure coding for all tenants and offer replication as an optional add-on
