Explanation/Reference:
The EMC RecoverPoint family provides cost-effective, local continuous data protection (CDP), continuous remote replication (CRR), and continuous local and remote replication (CLR) that allows for any-point-in- time data recovery and a new "snap and replicate" mechanism for local and remote replication (XRP).
Native replication support for XtremIO
The native replication support for XtremIO is designed for high-performance and low-latency applications that provides a low Recovery Point Objective of one minute or less and immediate RTO.
The benefits include:
Block level remote or local replication

Asynchronous local and remote replication

Policy-based replication to enable optimizing storage and network resources, while obtaining desired

RPO and RTO
Application-aware integration

Incorrect Answers:
A: OpenStack is the open platform for managing private and public clouds.
B: XtremIO with VPLEX and RecoverPoint is a valid solution, but it would be more costly.
